The federal tax credit for a refrigerated air upgrade is gone as of 2026, but you still have real ways to save in Albuquerque. If you install a qualifying heat pump instead of a straight AC, New Mexico’s Sustainable Building Tax Credit can knock up to $1,000 off your state taxes, or up to $2,000 if you qualify as low-income. PNM rebates and a state rebate program stack on top of that.
Here is where a lot of Albuquerque homeowners get caught. The big federal 25C credit that used to cover heat pumps and central AC expired on December 31, 2025. If you are pricing a swamp cooler conversion in Albuquerque right now, the savings you count on need to come from New Mexico and PNM, not the IRS.
This matters because the type of system you pick changes what you can claim. A plain refrigerated air conditioner and a heat pump both cool your house the same way in summer. But the state credit and the richer rebates are written around heat pumps, since a heat pump also heats. Choosing a heat pump over a straight AC can be the difference between qualifying for a state credit and qualifying for nothing. We walk every customer through that math before we quote a job.
Albuquerque sits in a spot that makes this switch make sense. Bernalillo County falls in the North-Central climate zone, so our winters are cold enough to matter but mild enough that a modern heat pump handles most heating days on its own. Our dry desert air is exactly why swamp coolers were everywhere here for decades. It is also why they struggle once monsoon humidity rolls in each July. That is the season most people finally decide to convert.
What are the tax credits in New Mexico?
New Mexico’s main tax credit for a refrigerated air upgrade is the Sustainable Building Tax Credit, specifically the Energy Conserving Products part. It covers qualifying air source and ground source heat pumps, heat pump water heaters, insulation, and ENERGY STAR windows and doors installed in existing homes. For a qualifying ENERGY STAR air source heat pump, the credit runs up to $1,000 for most households and up to $2,000 for low-income taxpayers. That amount includes both the equipment and the installation labor.
A few things to know before you count on it:
- The credit is nonrefundable for most people, so you can only claim back what you owe in state tax. You can carry unused credit forward for up to 7 years.
- If your income is under 200% of the Federal Poverty Level, the credit is refundable, meaning you can get it even if you owe little or no state tax.
- You must get a Certificate of Eligibility from the New Mexico Energy, Minerals and Natural Resources Department before you file.
One thing worth flagging: how a heat pump is paired with a gas furnace can affect whether it qualifies for the state credit, and the guidance on that is not black and white. If the state credit is a goal for you, we confirm eligibility for your exact setup before we quote the job.
What HVAC system qualifies for tax credit in 2026?
For the New Mexico credit in 2026, a qualifying ENERGY STAR certified air source heat pump is your path, not a standard air conditioner. The state’s Energy Conserving Products credit is written for heat pumps, so a plain refrigerated AC will not earn it. The federal credit that once helped both is a separate story: the federal 25C credit for HVAC expired at the end of 2025 and is not available for systems installed in 2026.
Qualifying is about efficiency, not just the ENERGY STAR label. The equipment has to meet ENERGY STAR performance values, or the equivalent performance values for our climate zone, and you verify the exact model through the ENERGY STAR product website or the AHRI directory. A model that looks similar on paper can fall one efficiency tier short and lose the credit. This is a big part of what we do when converting a swamp cooler to refrigerated air. We confirm the model qualifies before it goes on your roof, and we give you the AHRI documentation you need to file. Keep the itemized invoice and the manufacturer certificate with your tax records.
Are AC upgrades tax deductible?
For your primary home, a refrigerated air upgrade is not a tax deduction. A deduction lowers your taxable income. What New Mexico offers here is a tax credit, which is better in most cases because it reduces the tax you owe dollar for dollar. If your state tax bill is $600 and you claim a $600 credit, you owe nothing.
The word people should really care about is not “deductible.” It is “credit” and “rebate,” because those are what actually cut the cost of an Albuquerque conversion. A tax credit shows up when you file. A rebate is money off closer to the time of install. New Mexico’s Sustainable Building Tax Credit is a credit. PNM cooling incentives and the state HEAR program are rebates. The difference matters for planning, because a rebate helps your budget now while a credit helps at tax time. If you rent out a property or the system serves a business, different rules apply and some costs can be treated differently, so that is a question for your tax professional. For most homeowners upgrading the house they live in, think credits and rebates, not deductions.
What is the New Mexico rebate program?
New Mexico’s headline rebate program is the Home Electrification and Appliance Rebates program, or HEAR, funded through federal money and run by the state. Income-eligible households can receive up to $14,000 in total rebates for qualifying upgrades, with up to $8,000 available just for installing an ENERGY STAR certified heat pump. A swamp cooler conversion to a high-efficiency heat pump is exactly the kind of project this program was built for. HEAR requires you to use an approved program contractor and to meet income limits, so it is not for everyone.
On top of HEAR, PNM runs its own cooling rebates. Depending on the SEER2 rating and unit size, you can receive up to $600 for refrigerated air or heat pump systems, and PNM has more than one path to get there, including its Midstream program and the Home Energy Checkup. As a certified PNM rebate partner, we sign our customers up directly and handle the paperwork. These layers can often be combined, so the right heat pump can pull a state tax credit, a PNM rebate, and, if you qualify, a HEAR rebate. If you want to explore a full conversion to refrigerated air or a ductless mini-split, both can be built around these incentives. You can also reach us through our contact page to talk it through.
Leaving a swamp cooler behind in Albuquerque is not just about summer comfort, it is about which upgrade actually earns you money back in a market where the federal credit no longer helps. At Tru Mechanical, we handle every swamp cooler conversion in Albuquerque and match it to the incentives you qualify for, from the state Sustainable Building Tax Credit to PNM cooling rebates, and we handle the rebate paperwork as a certified PNM partner. We also offer financing through Wisetack if you want to spread the cost. Call us at (505) 328-0743 and we will map out exactly what your refrigerated air upgrade can save.
