A Guide to HVAC Repair and Replacement Costs

Many homeowners rely on their HVAC system year-round, especially during the summer and winter months. The thought of your HVAC breaking down and having to replace it can be nerve-racking, especially during a hot or cold spell. If you have a unit that needs an HVAC tune up or to potentially be replaced, you’re in the right place.

We’ll dive into all the things you need to know about HVAC replacement, from how much a new HVAC system is, to how to determine whether replacement is necessary, to whether a home warranty will replace your 
AC unit.

HVAC Unit
How much does an HVAC replacement cost?
If you’re considering replacement, you may be wondering how much a new HVAC system is. HVAC replacement costs can range up to $6,000* for an individual unit or up to $15,000 for a whole new system if you don't have a home warranty. HVAC service costs are one of the priciest when it comes to heating units or AC replacements, so you can expect about a third of the price of installing a new unit to go to labor. But if it looks like you need an entirely new HVAC unit, it’s safe to assume you’ll be spending thousands.

*Repair/Replacement costs ranges are the twentieth and eightieth percentile of U.S. costs as reported in A Study of Homeowners’ Appliance and Home Systems Service Experiences, a nationwide survey of homeowners conducted in 2024 by ClearVantage for American Home Shield. Further reproduction or use is expressly prohibited.

Considerations that affect HVAC replacement costs
Knowing how much a new HVAC system is might make you to think twice before you make your final buying decision. When your HVAC is on its last leg, it’s important to consider how the details of your current system and lifestyle will factor into AC replacement cost. Before diving into this big decision, here are a few important things to think through:

Type and size
From split systems and heat pumps to ductless mini-splits and packaged units, there are many types of HVAC systems. The one you choose should align with your home’s layout, your local climate, and your comfort needs.

Size matters, too. A system that’s too small won’t keep up on hot days, while one that’s too large could short-cycle—turning on and off more than it should—which wears out parts faster and wastes energy. A qualified independent repair Pro can perform a Manual J calculation (a fancy term for figuring out the right size based on your home’s specifics) to help you get it just right.

Fuel
The fuel you use to heat and cool your home also affects your HVAC replacement cost and long-term energy bills. Common fuel types include:

Electric: Often used in areas with mild winters. Easy to install, but can be more expensive to run depending on local utility rates.
Natural gas: Typically more cost-effective for heating in colder climates.
Oil or propane: Less common but still used in rural areas without natural gas lines.
Dual-fuel systems: Combine electric heat pumps with gas furnaces for efficient performance in varying temperatures.
Additional repairs, replacements, and additions
HVAC replacement isn’t always a one-and-done job. Depending on the age and condition of your existing system, you might need to replace or update additional components like the ductwork, thermostat, the electrical/gas connections, or your home’s insulation.

These add-ons can affect your AC replacement cost or total HVAC replacement cost, so it’s smart to get a detailed estimate upfront.

Energy efficiency
A newer system is more efficient as well as more reliable. That means potential savings on your monthly utility bills and a smaller carbon footprint. For peak efficiency, look for a high SEER (Seasonal Energy Efficiency Ratio) or AFUE (Annual Fuel Utilization Efficiency) on the units you’re considering. And keep an eye out for ENERGY STAR® certified systems, which are recognized for meeting strict efficiency guidelines.

While higher-efficiency systems may come with a higher upfront price tag, they often pay for themselves over time in energy savings, and can even boost your home’s value.

What is the best time to replace your HVAC system?
It may be obvious that it’s time to replace your HVAC system. Your unit may have needed several repairs over the past couple of years. Or maybe it’s not so obvious:

Your energy bills may be costing more than they usually do this time of year, or you’re finding yourself constantly adjusting the thermostat. This can be especially frustrating when trying to stay cool during a heat wave or warm during the winter.

Even if you perform regular DIY HVAC inspections, it’s not always easy to know when exactly your HVAC system needs an upgrade. But there are some common signs that it’s time for an HVAC replacement, or at the very least, an HVAC tune-up:

Weak airflow from the vents
Grinding, squealing, grating, or other weird sounds
Blowing warm air instead of cool or cool air instead of hot air
Moisture where it shouldn’t be, either from a leak in the outdoor unit or increased humidity in the ductwork
Smelly ductwork. Mildew or mold smells are common if the ductwork is getting moist, but burning smells are also a warning signal that your AC or heating unit could be dangerously malfunctioning
How often should you replace your HVAC?


ENERGY STAR recommends that homeowners replace HVAC systems every 10 to 15 years. That’s typically how long it takes for major HVAC components in modern systems to show wear to the point where it’s more cost-effective to replace them. And when you’re staring at that big HVAC replacement cost, remember that newer systems are more efficient, so at least your power bill should be lower.

Do I just need an HVAC filter replacement?
Generally, HVAC filters should be replaced anywhere from every 30 days to every six months, depending on the type of filter. The frequency of your HVAC filter replacement also depends on the air quality where you live, if you have pets, and the size of your home. Use a website like Filter buy or discounted offers from FiltersFast (AHS members save 10% and free shipping on every order) to find the right HVAC filter for your system. Once you have your new filter, a trusted AHS Pro can help you install your new HVAC filter.

What to look for when buying a new HVAC unit
With so many HVAC options out there, deciding which unit to purchase can be overwhelming. Here are some important considerations:

1
Use the right professional repair Pro
Your new HVAC unit’s efficiency can be determined by its installation, so it’s imperative that you work with a quality pro. Interview several candidates and get detailed quotes from each.

2
Determine the correct unit size
The best way to get an accurate size estimate is to have your home professionally evaluated. Make sure your Pro performs a load calculation, which takes into account the size of your house, the climate, the roof material, the orientation of the unit, the number of units, and more. An HVAC installation Pro will consider factors like whether or not your home has a crawlspace or basement, how much insulation there is in the attic, how many floors it has, the number of people living there, what kind of doors and windows it has, how high the ceilings are, and what your desired indoor temperature is. Most homes will need a new HVAC unit sized around 20 BTUs per square foot.

3
Don’t ignore the SEER rating
The higher the Seasonal Energy Efficiency Ratio (SEER) rating, the more efficient the unit. Although a unit with a higher SEER rating may be more expensive, it could end up saving you more money in the long run.

How to save money on a new HVAC unit
Replacing your HVAC system isn’t a small expense. Luckily, there are smart ways to soften the blow. For starters, if your current unit is on its way out, you could qualify for federal tax credits just by choosing an energy-efficient system. Look for air conditioners and heating units labeled ENERGY STAR® Most Efficient, which meet the standards required for the tax credit.

Beyond federal tax incentives, many states and utility providers offer additional rebates that can help lower your HVAC replacement cost even further. It’s worth checking what’s available in your area—you might be able to get a portion of your installation costs back just for choosing a more efficient system.

Will a home warranty help replace your AC unit? The American Home Shield® New HVAC Program can help take the sting out of needing a new unit. If your covered system can’t be repaired, we can help with AC replacement costs, helping you stay in control of your home and your budget. Combine that with the protection our home warranty plans provide for your other appliances and systems—no matter their age—and it’s a solid step toward saving money today and protecting your peace of mind tomorrow.

What to keep in mind after the HVAC replacement
Nothing says “investment” like a home system that you paid a pretty penny for. Whether you just replaced a tired old unit or upgraded to something high-efficiency, one thing’s for sure: you’ll want to keep it running at its best for as long as possible.

Even the most reliable systems can hit a snag now and then. That’s why regular maintenance is key—and why having a plan in place to protect your budget from surprise repair costs can give you serious peace of mind.

Here are a few simple ways to take care of your new system:

Change your air filters regularly—usually every 1–3 months, depending on usage.
Keep the outdoor unit clear of debris like leaves, branches, and dirt.
Schedule professional tune-ups at least once a year (spring for AC, fall for heat)
Seal up drafty windows and doors to keep your system from working overtime.
Check your thermostat settings to make sure your system isn’t running harder than it needs to.
Of course, even with great care, breakdowns can still happen. For covered breakdowns, that’s where we come in.

12 Questions to Ask an HVAC Installer When Replacing Your Unit

Your heating and cooling system plays a crucial role in your home, so when it’s time for an HVAC replacement, you have to do your homework. Start by researching HVAC companies near you to compare quotes, find licensed technicians with positive reviews and choose one best suited for your needs. Ask for itemized cost estimates to understand where your money is going and protect yourself from unexpected costs.

No matter what kind of system you’re considering, it needs to fulfill two duties — keeping your family as comfortable as possible and your bills low. Luckily, choosing a system that does both can be as easy as asking the right questions.

Building your understanding of HVAC systems helps you make efficient and cost-saving decisions concerning your home’s cooling and heating. Ask your HVAC contractor the following questions and you’ll be on the right track to a new installation that’s perfect for your home:

1. What Size Central HVAC Unit Do I Need?
Ask the technician how they analyze your space to determine the correct size that will maximize your home’s efficiency.

While a one-year warranty is the industry standard, HB Home Service Team offers special plans of up to three-year warranties for labor, parts and 24-hour emergency response.

4. What Equipment Do You Recommend, and Why?
HVAC contractors are experts in their field. After performing installations in many different homes for years, they can make an educated recommendation about what will work best in your home!

5. Do You Have a Service Plan to Maintain and Protect My System?
Your relationship with your HVAC company shouldn’t end after installation. Check if they offer service plans to keep your system running smoothly over the years. A company that provides all services under one roof saves you the hassle of researching again the next time your equipment needs inspection and repairs. HB Home Service Team offers preventive maintenance and comfort agreements with our Gold Shield Plans.

6. How Efficient Will My New HVAC System Be?
Efficiency is key to long-term savings. Discuss factors such as the system’s SEER rating, lifetime operating costs and filter types to ensure you choose a system that balances upfront costs with long-term energy savings.

7. What Payment Options Are Available?
Find out what kind of payment and financing plans your HVAC company offers. It’s important to be aware of these options from the very beginning of the process. Some companies partner with financial providers to bridge the gap between the cost of a new system and available cash. This helps ease the stress on your cash flow while ensuring a successful home improvement project.

8. How Can I Improve My Indoor Air Quality?
Your HVAC system plays a crucial part in your home’s air quality, in addition to heating and cooling. If you struggle with allergies or humidity, an HVAC technician can offer advice on creating a healthier environment. For instance, disposable, washable HEPA filters can improve indoor air quality and safeguard your family’s health.

9. Are There Any Special Offers or Rebates That I Can Claim?
From tax and utility rebates to special equipment discounts, your HVAC contractor will be able to tell you if you qualify for any money-saving offers.

10. Are There New Technologies I Should Consider?
Ask about cutting-edge advancements in new HVAC technology that can benefit you. A qualified technician can suggest other upgrades such as insulation, programmable thermostats and duct sealing to enhance your system’s performance. Consider options like renewable energy systems, geothermal and advanced zoning solutions, which are becoming more affordable and can improve your home’s comfort and efficiency.

11. What Brands Do You Sell and Service?
Knowing which brands your contractor sells and services allows you to research their reliability and performance, helping you make a more informed choice. Request a list of brands your contractor recommends and reasons why.

12. Can I Use My Current Air Ducts?
Reusing existing air ducts can save you money, but only if they are in good condition and compatible with the new system. Have your contractor assess their suitability to ensure optimal performance.

Yes, winter HVAC replacement is often worth it because you get better pricing, faster service (less busy season), immediate comfort before extreme cold, and long-term savings from higher energy efficiency, plus you avoid the rush and potential supply chain issues of summer. It's a smart move to upgrade an old, inefficient system for peace of mind and lower bills all year.
Benefits of Winter Replacement

Should I Replace My AC Unit In The Winter?
Replacing your air conditioning system isn’t something you look forward to unless you’ve been doing without. AC replacement is an investment that involves a lot of decision-making and finding a trustworthy HVAC company. However, you can make the process easier in a way you might not expect: by choosing when to replace your system.

Determining When The Investment Is Worth It
Purchasing a new cooling system is a sizable investment. So in many ways, your decision comes down to weighing the cost and time needed versus what you get out of the deal.

Major considerations include:

The age of your current system: Cooling equipment can be expected to perform effectively for 10 to 15 years when they’re properly maintained. Past this point, you’ll see more frequent repairs and overall weaker performance.
Whether your current system can keep up: Does your system struggle to keep your home cool, or does it leave your home feeling humid? If so then there’s no reason to keep paying the upkeep on it. Just replace it for better results.
Your current average utility costs: Noticing a trend of higher energy costs with each summer? This is a sign that a replacement will save you cash in the long run.
How often you need repairs: A single cooling repair, depending on the nature of the issue, is usually reasonable. But that changes when you need repairs yearly or even more often.
How costly the current repairs are: Some repairs, such as compressor replacement, can cost you an arm and a leg. When repair costs start to cost around $400 to $500 or more, it’s best to discuss replacement with your HVAC contractor.
The Perks Of A Winter Purchase
Winter is one of the prime off-season times for cooling systems. Along with fall, purchasing a cooling system in off seasons can present you with some considerable benefits.

Many contractors and manufacturers offer incentives for purchasing and pursuing a new installation in the off-season, which can give you immediate perks like reduced labor or parts costs, improved warranties, and similar benefits.

Replacing in the winter can also give you another underrated asset: time. Time to pick the perfect system for your needs, time to shop around (both for a contractor and the ideal system), and time to make sure you’ll be prepared for summer.

Should You Replace Your AC & Furnace At The Same Time?
Many homeowners choose to replace their furnaces when replacing their AC, which has several benefits. There are two main things to consider when weighing your options:

Age of both units: If both of your units are more than a decade old, it might make sense to replace your furnace along with your air conditioner to get ahead of expensive repairs as your furnace ages.
Energy efficiency: If you’re upgrading to an energy-efficient cooling system, it makes sense to do the same with your furnace to maximize your home’s energy efficiency.
However, if your furnace is less than 10 years old and works fine, we don’t recommend bundling your furnace replacement with your new AC installation. If you’re looking for cost-efficient heating upgrades, you could also consider a heat pump installation.

Repair Or Replace: How To Make An Informed Decision When Your Commercial HVAC System Is Down During Winter

When your commercial HVAC system is down, it can be hard to decide whether it needs to be repaired or replaced, and if it’s down during winter, it’s especially important to get it up-and-running as soon as possible.

If your HVAC system has leaks, makes odd noises, or has any kind of similar defect, you’re usually faced with two options: repair or replace it. While replacement parts can be costly, there are some instances where this is the best, and even most cost-effective option, especially during winter. Continue reading to find out more.

Why Might I Need To Repair Or Replace My Commercial HVAC System?
Whether your commercial HVAC system needs major repairs or replacement parts entirely depends on what’s wrong with it, the age of the unit, the circumstances surrounding it, and the extent of your budget. For example, if your HVAC system is down during the winter, not only could your operations be put on hold, but your building will also run much less efficiently, costing you money. In these cases, fixing the problem as soon as possible is the best course of action, so if it’s repairable, this is usually the quickest and most immediately affordable option.

Sometimes, however, continually repairing faulty components can end up costing you more than replacing them with higher quality parts. This may be more expensive up-front, but it will save you money in the long run by extending the work life of your HVAC system and optimizing its performance.

The life expectancy of your HVAC system depends on several factors, including:

Whether there’s been regular maintenance of the HVAC system
The  amount of use (load on system), which determines how likely it is to break down
The quality, wear life, and durability of its components
Overall design of system and any changes in building
It’s also important to remember that different parts of an HVAC system have different life expectancies. Mechanical or moving parts, for example, have a much shorter wear life than structural parts because of how much friction they experience. Structural parts, like a typical air conditioning compressor, on the other hand, have a lifespan of around 10 to 15 years.

So, as a rule of thumb, you should always opt for replacing an HVAC component if it’s reached its optimal life expectancy. This should mean that your system will always be running safely and efficiently. Similarly, you should repair a component if it’s relatively new and the defect or damage isn’t too severe. In most cases, you can save money if you choose to repair something – just make sure that the system or component can be repaired without sacrificing reliability and longevity of your entire commercial HVAC system.

How Do I Decide Whether To Repair Or Replace My System?
Deciding whether to replace or repair your HVAC system pretty much boils down to the economic factor, which, of course, is crucial when you’re running a business. The first thing you should ask yourself is whether or not you will be able to save money in the long term.

As we’ve just explained, repairs are usually sufficient – but if your system is old, inefficient, and needs constant repairs, you’ll be better off choosing to replace the problem part in your HVAC system. This will ultimately save you money and quite a lot of effort, but always consult experts in HVAC systems before you decide.

Of course, there’s always the last resort – do you actually need to replace your entire HVAC system? If it’s so old that it is run on R-22 refrigerant or  seemingly built from replacement parts, it  is worth investing in a new system. With the EPA phase out of R-22, the refrigerant and replacement part costs will only continue to skyrocket. In the long run, it will be more efficient and you’ll start seeing savings on your energy bills which will go a long way in offsetting the cost of having a new system fitted.

What Should I Consider?
There are several things to consider when deciding to either replace or repair components in your HVAC system. These are primarily concerned with the life expectancy of the system, and include:

The age of the system: Older systems are less efficient and are usually prone to breakdowns. If your HVAC system falls into this category, you’d be better replacing it or the specific part, especially if it’s older than decade.
Environmental factors: Extreme weather conditions, from long winters to sudden heat waves, can take a toll on the performance of your commercial HVAC system. While very high temperatures makes the A/C work harder, low temperatures mean more work for the heater. Other environmental factors to consider are humidity and sea mist, which can cause corrosion.
Airflow: The compressor or condenser in your HVAC must be placed in a location that has sufficient airflow. If not, the motor will have to work a lot harder, leading a shorter wear life as it will be exposed to more friction and corrosion.
Energy efficiency of the components: Some components that have been installed for over ten years are less efficient compared to high-quality components on the market today. If you’re struggling to fix your HVAC system, first figure out how much you would save on repairs and electricity bills if you upgraded to more efficient components.
Size of the system: HVAC systems that are properly measured and fitted for the building they’re meant to service are more likely to last longer. This is because the performance of these systems will be optimized for the space they’re in, meaning that they won’t under or over perform.
Regular maintenance: HVAC systems that are regularly maintained will have better longevity than those that are ignored – or only looked at when something goes wrong. Quarterly or semi-annual checkups are necessary if you want to correct minor defects before they become major breakdowns. From inspecting electrical components to checking for leaks, periodic maintenance will significantly extend the service life of your HVAC system.
Is It Cheaper To Repair Or Replace Parts In My HVAC System?
Generally speaking, it’s more affordable to opt for repairing your HVAC system than to replace it. However, repairing an old system is usually not cost-effective over a long period of time. Not only will this burden you with constant repairs, it will also drive up your building’s electricity bills because of the inefficiency of the system. With that in mind, replacing parts in your HVAC system is more cost effective if they’re outdated or experience frequent problems.

Replacing an HVAC system before summer is smart to avoid peak-season delays, get better scheduling, take advantage of spring deals/rebates, ensure reliability before heavy use, and upgrade to more efficient, quieter models for lower bills and better comfort. It prevents breakdowns in extreme heat, offers more choices, and improves indoor air quality, making spring the ideal time for this investment, says Fleetwell USA.
Benefits of replacing before summer
Avoid peak demand: Contractors are less busy in spring, so you get faster, more flexible scheduling and avoid costly emergency fees during heatwaves.
Save money: Take advantage of spring sales, manufacturer rebates, and potential tax credits before summer prices rise.
Boost efficiency: New systems offer significant energy savings (up to 40%) over older models, reducing your summer energy bills.
Ensure comfort: A new unit provides consistent cooling and better humidity control before the heat becomes intense.
Prevent breakdowns: Replace an aging, unreliable system proactively to avoid mid-summer failures, notes Gentry Air Conditioning.
Signs your system needs replacing soon

This article will outline why replacing your HVAC system before summer hits is the best move and allow you to continue your journey to finding the right AC and HVAC company for you.

​​Why It’s Smart to Replace Your AC Before Summer
If your air conditioner is nearing the end of its life or you’ve been considering an upgrade, the time to act is before the summer heat sets in, not during it.

Here’s why scheduling your AC replacement in the spring, or even late winter, is one of the smartest decisions you can make for your home’s comfort and safety.

1. You Can Avoid Peak-Season Delays
Summer is the busiest time of year for AC companies, especially in Texas. With the extreme heat pushing systems to their limits, technicians are booked out for weeks with emergency calls and last-minute replacements.

By planning ahead and replacing your system in the off-season, you’ll beat the rush and avoid the stress of waiting in the heat for an appointment.

This is also a sure way to avoid going without heat during the summer in case your AC completely shuts down.

2. You Have Easier, More Flexible Scheduling
During spring and early fall, otherwise known as the off-season for HVAC companies, there are typically more openings in companies’ schedules.

That means you get more flexibility to choose a day and time that works best for you, not just the first available slot. This makes the whole process a lot more convenient, and, again, allows you to avoid the stress of waiting for a replacement when you really need it.

3. You Have More Time to Make the Right Choice
When you’re not under pressure to fix a broken system in the middle of a heat wave, you have the time to shop around and compare systems and their features and thoroughly research the right HVAC company to work with.

Finding the right company to work with is one of the most important parts of your AC replacement. Even if you choose the highest-rated system, if it isn’t installed properly, it will fail, making your project more costly and frustrating.

Thoughtful planning can lead to better long-term results and reliable comfort with a company you can trust.

4. You Can Avoid Emergency Breakdowns
Older systems are more likely to break down when they’re working hardest, which is exactly what happens in the middle of a Texas summer.

Swapping out your aging unit before temperatures hit over 100 means peace of mind, reliable comfort, and no unexpected emergency service calls.

If your system is over 10 years old, scheduling an inspection before summer will allow a professional to assess your equipment and provide you with the right solution.

5. You Can Improve Energy Efficiency Before High Usage
Newer AC systems are significantly more energy efficient than older models. In fact, a new HVAC system can potentially reduce annual energy bills by 30%, according to the U.S. Department of Energy.

By upgrading before the warmer months begin, you’ll immediately start saving on your utility bills right when you’re using your system the most.

6. You Receive Access to Potential Seasonal Savings
Many HVAC companies offer discounts, rebates, or special financing options in the off-season to keep their technicians and installation teams busy before the summer surge.

That can translate into hundreds or even thousands of dollars in savings when you time your replacement right.

Is Now the Right Time to Replace My HVAC System?
Now you have a full understanding of the benefits of replacing your HVAC system before the peak summer season and can continue your research to find the right products and company to work with.

Replacing your HVAC system is a large investment in your home, and it’s important to thoroughly research different products, models, and companies in your area before making a quick decision.

If you’re considering replacing your HVAC system, it’s also essential you understand the common signs it’s time for a replacement to know how this investment will benefit you.

Some of the most common signs it’s time for a replacement include:

Your system is 10-15 years old
You’ve noticed higher energy bills
You notice more dust in your home
The unit is loud and noisy
You’re spending a lot on constant repairs
Replacing your old, worn-out AC won’t only improve your home’s comfort but will also save you on energy bills in the long run.

So, if you’re ready to replace your HVAC system, understanding when and why you should do it now is the first piece of the puzzle. The next thing you want to know is how much it’s going to cost.

Because this project is an investment, it’s important you not only see the price tag but completely understand all that it encompasses.

The Best Time of Year to Replace Your HVAC System

Sometimes, it’s easy to know when you should get a new HVAC system.

If it’s early August, your ancient AC won’t turn on, and the HVAC technician says the problem is an expensive part or an R-22 refrigerant leak, it’s probably time to replace your air conditioner.

To do otherwise would be like buying a new transmission for a 1996 Dodge Stratus. There’s just no use in throwing money at something likely to break down again the next day.

But there are other times when the choice isn’t so cut and dry — like when your old system still works, but you feel like it’s about to start giving you problems.
Or when it already is causing problems.

Signs it’s time to replace a working HVAC system
Before we discuss the best time of year to replace your HVAC system, let’s consider why you might replace an air conditioner or furnace that still works:

The system is over 15 years old: This is the point at which many ACs and furnaces start having problems. Often, the problems are small things like a dead capacitor or control board that can easily be switched out. But small issues are often a harbinger of bigger things to come. If you’ve got a fifteen-year-old system with a bad compressor or a refrigerant leak, replacing it is a no-brainer.
You’ve already spent a lot of money on repairs and now there’s another problem: This is the same point at which you would sell your old car as-is and get another one.
You’re ready for a more efficient system: Compared to the HVAC system you bought during the Bush administration, today’s options — even at the budget level — are significantly more efficient. In addition to variable speed and two-stage systems, you can get a new AC with a SEER of up to 25! More furnaces also have variable speed blowers and modulating gas valves.
The AC uses R-22 refrigerant and leaks: Ever since the EPA ban on R-22, the old type of freon has gone up in price. Adding R-22 to an old AC is pretty expensive, especially when you consider that an old system is likely to leak again. It’s usually more cost-effective to just get a new AC that uses the future-proof R-410A refrigerant.
You already need to replace either the AC or the furnace for some reason: When your air conditioner and furnace are the same age, it’s usually more cost-effective to replace both at the same time.
So, yes. There are times when you might want to replace a working furnace and/or AC. And if you’ve decided to do so, there is absolutely the best time of year to do so.

There are two.

You can replace your HVAC system during any season, but these two are the best.
Fall and spring. Those are the two best times of year to replace your HVAC system.

After that, any time other than what HVAC companies describe as “peak season” is a pretty good time. Here in Atlanta, the peak seasons for HVAC service are the hottest weeks of summer and the coldest weeks of winter. And of the two, summer is busier by far. That’s just the way it is here in the sweltering South.

Why fall and spring? Here are a few reasons:

You may be without AC or heat for a few days. That might sound horrible. And in July or January, it is horrible! But in March or October, it’s usually not a big deal to have your HVAC system replaced. Most people do just fine without AC or heat for a few days in the spring or fall.
Your HVAC company isn’t very busy. At PV Heating, Cooling & Plumbing, we field the most service calls during peak summer and, to a lesser extent, peak winter. These are the times of the year when ACs and furnaces are working the hardest. By the same token, it’s when they tend to break down. If you want to replace your AC in the spring or fall, there’s a good chance we can get you on the schedule right away.
Better pricing: Since there’s less demand for HVAC system replacement in spring and fall, your HVAC contractor might even offer their own savings incentives.
Manufacturer promotions: Less demand for installations leads to some pretty compelling incentives from equipment manufacturers. Trane, for example, regularly offers special financing and rebate opportunities during the shoulder seasons.
There are lots of good reasons to replace an HVAC system in October instead of, say… August. The installation can usually happen on your schedule; you save money, and nobody has to suffer from extreme heat or cold during the process.

Aren’t sure your AC is cut out for another summer? Worried your furnace might struggle through the winter?
At PV Heating, Cooling & Plumbing, we can analyze your HVAC system and let you know whether now a good time is to replace it.

If your AC and furnace still have life in them, we’ll let you know.

In many cases, there aren’t any apparent problems that need to be addressed before the AC is tasked with another summer of cooling or the furnace switches on for another winter. But other times, there are. We’ll always engage you in a candid, fully transparent conversation about what is or isn’t going on with your old HVAC system.

Signs your HVAC is failing include strange noises, frequent/costly repairs, higher energy bills, uneven heating/cooling, poor airflow, weird smells, and the unit being over 10-15 years old, indicating it's time to consider replacement over constant fixes.
Performance Issues
Runs Constantly or Short Cycles: The unit runs non-stop or turns on/off frequently (short cycling) but can't maintain temperature.
Uneven Temperatures: Some rooms are hot while others are cold.
Weak Airflow: Air coming from vents feels weak or inconsistent.
Poor Humidity Control: Your home feels stickier or more humid.
Blowing Warm Air (AC): The AC blows warm air instead of cool air.
Sounds & Smells
Banging, Grinding, Squealing: Indicates loose parts, motor issues, or worn-out components.
Hissing/Whistling: May signal duct leaks or refrigerant problems.
Musty/Moldy Smell: Often means moisture/mold in the system.
Burning Smell: Can point to electrical issues, requiring immediate attention.
Rotten Egg Smell: Could be a dangerous natural gas leak (furnace).
Cost & Age
Rising Energy Bills: The system works harder and uses more energy to do its job.
Frequent Repairs: Calling for service multiple times a season signals the system is on borrowed time.
Age: Units typically last 10-15 years (AC) or 15-20 years (furnace), so systems near or past this age are prime candidates for replacement.
When to Replace vs. Repair
If repairs are becoming constant and expensive, investing in a new, energy-efficient unit often saves money long-term compared to constant fixes on an old system.
Consider the cost of ongoing repairs versus the long-term savings and increased comfort of a new system with a warranty.
