When Is the Best Time to Buy New HVAC Equipment?

Replacing an old HVAC unit is a significant decision that requires a lot of thinking and planning. Since you’ll be spending thousands of dollars on a new system, you need to make sure that you’re really putting your hard-earned money into a worthy investment. Moreover, you have to ensure that the replacement is really necessary.

In this post, HVAC installation expert Custom Air Systems shares a comprehensive guide for buying a new HVAC unit. We discuss the best time of the year to make a purchase, the different signs that will tell you when it’s time for a replacement, other important considerations to think about when making a decision and a few essential tips on buying an HVAC system.

During the Off Season

It’s common for people to think that the best time to buy an air conditioner is during the winter, and the best time to buy a heating system is in the summer. The rationale is pretty simple — since air conditioners aren’t in use during cold weather and heating systems aren’t needed when the weather’s hot, stores will be selling them at lower prices. This is not always the case, however.

Remember that winter and summer are usually the seasons when HVAC systems are heavily used. This means that many HVAC companies are also busy during these times of the year carrying out repairs and maintenance as well as selling units. Business is generally at its peak in the summer and winter, so many HVAC companies are less inclined to offer discounts and sales. Booking their services might be a problem also.

This leaves spring and fall as the ideal times to get an HVAC replacement. During these seasons, most people aren’t running their heating and cooling systems as often, so HVAC services and products aren’t in much demand. HVAC companies may decide to reduce the price of their units so as to move stock quickly. This is especially the case when suppliers and manufacturers need to clear older stock because new models will be arriving the following season. Naturally, with cheaper HVAC units, contractors are able to pass along the savings to their customers.

That said, if you aren’t in a hurry and your HVAC system doesn’t necessarily need urgent attention, you might want to consider scheduling your heating or air conditioning replacement in the fall or spring.

Signs to Look Out For

To give you an idea of when an HVAC replacement is urgently needed, here are a few signs to watch out for:


HVAC systems can only last for so long. Typically, they’re designed to last for approximately 10 to 15 years, depending on the care and maintenance they receive. So if your HVAC system is around 15 years old and is no longer heating or cooling the way it used to despite regular upkeep, it might be time to get a new unit.

Frequent Repairs

If you’ve found yourself calling a technician several times over the past several months or even the past year because your HVAC system is repeatedly acting up, you might want to consider the possibility that it’s time to replace the entire system. Constantly repairing your failing HVAC unit will only cost you more in the long run, so you might want to put your money into a new system instead. In addition to saving you from costly repairs, this can also eliminate the frustration and hassle that you have to deal with.

Other Factors to Consider

It may also be a good idea to buy a new HVAC system in the following circumstances:


If you’re doing a renovation project, you might want to kill two birds with one stone by installing a new HVAC system as well. This way, you’ll only have to deal with a major disruption once. This can also provide you with an opportunity to reassess the energy efficiency of your home and incorporate designs and systems that will better serve your energy efficiency goals.

Purchasing a New Home

If you’re purchasing a new-build home, you have the freedom to choose everything, including the type and brand of HVAC system that you’re going to use. If you’re buying a previously-owned home, this could also be an opportunity to get a whole new HVAC system since the existing one may no longer be in top condition. In addition to the HVAC system, make sure to have an expert check for issues in the home that could potentially affect the performance of your HVAC system, such as air leaks or inadequate insulation.

Special Offers

It doesn’t hurt to always be on the lookout for specials and discounts that may be offered by HVAC companies. These could happen any time of the year; some deals are even offered year-round. At Custom Air Systems, we run a bunch of promos that can provide value for your money. We have a 10% senior citizen discount on any type of HVAC replacement, a 15% discount on any replacement or repair for military, veteran and first responders; a special rate for AC and heating tune-ups; and many more.

Tips on Buying a New HVAC System

Once you’ve made the decision to purchase new HVAC equipment, there are certain considerations that you have to take into account to ensure that you’re getting the right unit for your home. That said, make sure to consider the following:

Type of Unit

Different types of HVAC systems are available on the market, so if you feel like your old HVAC system isn’t able to meet your needs and you want to upgrade, make sure to do your research about these various types of HVAC systems. Your choices include ductless mini-split systems, window units and heat pumps.


Ensure that you’re getting an HVAC unit with a capacity equal to the amount of space that you have. If your unit is too small or too big for your home, you won’t be able to make the most of it. It’s best to have an HVAC professional take a look at your home to determine the right size since it takes more than just square footage to do so.


The cost of a new HVAC system depends on the type of system you need as well as the features it has. The price difference between lower-end central cooling systems and premium models can be great, and it’s usually based on factors like the brand, the type of system, the size of your home and other additional products that you might want to get like air purifiers, humidifiers and smart thermostats.

Tax Credits & Rebates

If you’re switching to a more energy-efficient HVAC system, you might be able to qualify for tax credits and rebates — which could lower your expenses. Make sure to ask your HVAC contractor about these tax credits and rebates.
