When you’re trying to stay cozy during harsh winter temperatures, the last thing on your mind is your air conditioner. But if your AC unit is showing signs of disrepair or old age, it’s wise to consider the best time to buy an air conditioner. Let’s take a look at the best time to buy an HVAC system, plus some tips on when to hire an AC installer and which type of unit is right for you.

When Is the Best Time to Buy an Air Conditioner?

The best time to purchase an air conditioner is the fall or spring. HVAC installers in your area will be busy during the summer and winter months when outdoor temperatures are the most extreme. 

Avoid these busy periods and you’ll likely find better deals before consumers start swarming stores looking for air conditioning units. This is because retailers are always looking to get rid of the previous year's models to make space for newer versions.

Additional Times to Save on Buying a New AC System 

There are many other optimal times to buy a new AC system aside from seasonal shifts. For example, you should consider replacing the AC unit when renovating your house, especially if you’re changing the interior layout. 

If your AC unit is showing warning signs that it’s slowing down, such as burning smells, strange sounds, or refrigerant leaks, it’s easier to replace it during renovation or new addition projects than retrofitting them after the work is done. To snag an even better deal, consider buying a new AC when you need to replace your furnace or other parts of your HVAC system for a potential bundling opportunity.

Ways to Save When Buying an AC Unit

If you’re searching for ways to cut costs when purchasing a new AC unit, try these tips:

  • Check for tax credits and rebates: According to Energy Star, you can receive up to a $300 tax credit for installing a new AC unit that meets energy efficiency standards and guidelines. Plus, some states and local utility companies provide rebates for replacing an outdated AC system.

  • Consider your needs: If you only use a few rooms in your home, you might think about installing a ductless split system (rather than central AC). You won’t get whole-house cooling, but you could save a fair bit on installation.

  • Think long-term: When purchasing a new unit, ask the sales company about free upgrades to your unit or discounts on future services. 

  • Bundle services: If your furnace is nearing the end of its life, consider replacing it when installing your new air conditioner. This lets you avoid separate HVAC service calls and ensures that the different parts of your HVAC system work together seamlessly.

  • Improve your home’s insulation: If your house has poor insulation, the cool air coming out of your AC unit is more likely to leak outside, increasing your energy costs. Fortunately, there are several simple ways to improve your home’s insulation, including weather-stripping doors and windows, adding thermal curtains, and sealing electrical outlets.

How to Pick an AC Unit That Meets Your Needs

As you search for an air conditioning unit during the offseason, now is the best time to evaluate your home’s cooling needs. Some factors to consider before buying a new unit include:

  • Your home’s size

  • Current HVAC unit type

  • Climate in your area

  • Upgrades

  • Energy efficiency

  • Necessary system features

  • Budget

Calculating your home’s cooling needs requires the help of an HVAC professional. They use Manual J guidelines, which can be pretty complex for homeowners, and any errors could cost you money in the long run.

DIY vs. Hiring a Pro

Purchasing and installing an air conditioner is a job best left to the pros. We recommend hiring an air conditioner installer near you to ensure your system is installed correctly and functions properly. You’ll pay $1,500 on average in labor costs for an HVAC replacement. However, you’ll have peace of mind knowing that your new system will work properly and safely.

Frequently Asked Questions

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs. 

On average, an AC unit will last between 10 and 20 years. However, air conditioner lifespans depend on a few factors, including the type of AC you have, how often you run it, and how well you maintain it. For example, central AC units last between 12 and 17 years, while window units last for eight to 10 years. Also, the more you run your AC, the quicker it will wear out, but keeping up with regular maintenance can help it last longer.
