Federal Tax Credit for HVAC Systems: How Does it Work and How to Claim (Step-by-Step Instructions)

Here’s the deal. So you bought a new HVAC system in 2020 and you heard you might be able to get a Federal tax credit. But how do you go about it? The great news is you can claim it when you file your income taxes in 2021, so now is the time to act!

The best part? For qualified HVAC improvements, homeowners might be able to claim 25c tax credits equal to 10% of the install costs (up to a maximum of $500).

If you’re unsure of how to get the tax credit you might be eligible for, don’t worry, we’ve got you covered. Read on through this post to learn about the eligibility criteria of the federal tax credit scheme for high efficiency HVAC systems, and find out how you can claim some money back.

What is the Federal Tax Credit for High Efficiency HVAC Systems?

 The Nonbusiness energy property tax credit provides an incentive to homeowners to invest in energy efficient home improvements, such as high efficiency heating, cooling and water-heating equipment. It’s a non-refundable personal tax credit, i.e., reducing taxes, dollar-for-dollar. It was enacted as part of the Energy Policy Act of 2005 and has been expanded multiple times, now to December 31st, 2021.

Why is this important? Well, this means that any purchase of a qualifying high efficiency HVAC system throughout 2021 is covered by the tax credit.

How Does Energy Tax Credit Work and How Much Will I be Given?

Federal Tax Credit HVAC Eligibility Table

 Although it sounds quite complicated, once you get to know the details, it’s not too difficult to understand. Thanks to the tax credit, homeowners will receive a credit against their taxes for an amount equal to

  • 10% of the amount paid or incurred up to $500 or a specific amount from $50 – $300.

I’m not going to lie to you, there are some specifics you need to be aware of. In the following section we use some abbreviations, which are explained below:

  • SEER – Seasonal Energy Efficiency Ratio, it measures how much heat is removed by an AC or Heat Pump in watt-hours. The higher the ratio, the more energy efficient.
  • EER – Energy Efficiency Ratio. It measures how efficient an AC or Heat Pump operates when outdoor temperature is 95F.
  • HSPF – Heating Seasonal Performance Factor. It measures the ratio of heat output from an Heat Pump to electricity used.
  • AFUE – Annualized Fuel Utilization Efficiency. It’s a percentage used to rate furnace’s heating efficiencies. The higher the percentage, the more energy efficient.

How do I find out the SEER, EER, HSPF, and AFUE of my HVAC system?

The best way to find out this information is to contact the HVAC contractor who installed your system. Here at SuperTech, we provide that information in our install contracts, and if you’re unsure you can always give us a call.

Air Source Heat Pumps

You can qualify for tax credit up to $300. They are required to have a minimum of 15 SEER, 12.5 EER, 8.5 HSPF.

Central Air Conditioning

You can qualify for tax credit up to $300. Split systems must have a minimum of 16 SEER and 13 EER whereas packaged systems must meet or exceed 14 SEER and 12 EER.

A split system is split into two units: one that’s inside and one that’s outside.

On the other hand, packaged systems have all of their main components (condenser, compressor, and evaporator) combined together in one single, metal-encased package.

Gas, Propane, or Oil Hot Water Boiler

You can qualify for tax credit up to $150. They must meet or exceed a 95% AFUE.

Gas, Propane, or Oil Furnaces and Fans

You can qualify for tax credit up to $150. They must meet or exceed a 95% AFUE.

Water Heater (non-solar)

You can qualify for tax credit up to $300.

Advanced Main Air Circulating Fan

You can qualify for tax credit up to $50. The advanced main air circulating fan must not use more than 2% of energy.

Am I Eligible to Claim HVAC Rebate?

 It sounds great, doesn’t it? But what’s the bottom line? How do you know if you’re eligible?

First up, if the system meets the qualifications in the section above, it’s energy star certified. This proof is often in the form of an AHRI certificate or a manufacturer certification. As a homeowner, you should keep proof for your own records, but you don’t need to attach to your tax return when you file. If you don’t have the proof, reach out to the HVAC contractor installed your system. In addition, to be eligible for the tax credit, the system must be installed at your existing home, which is also your primary residence.

Unfortunately, tax credits are not available for new constructions or rentals, so it’s only for systems that you replaced or added at your current home.

Also, if you’ve already claimed $500 from the Non-business Energy Property Tax Credit since 2005, you won’t be eligible to claim any more credits.

How to Claim Residential Energy Credit?

First things first, to claim your tax credits, be sure to keep a copy of the AHRI certificate (example shown above) or the manufacturer’s certification statement (example shown above) to show the efficiency ratings of the system. You won’t qualify for the credits without one.

In order to apply for the tax credit, you need to file IRS Form 5695 with your tax return, which we will go through in the following section.
