Rebates & Savings on a New HVAC System

A high-efficiency system can qualify for federal tax credits and local utility rebates. Here's how the savings generally work — and how to confirm what you'll actually get.

This is general information, not tax or financial advice. Credit and rebate eligibility depends on your situation and the exact equipment installed, and program rules change. Confirm current details with a tax professional, the IRS, and AEP Texas before counting on a specific amount.

Upgrading to a high-efficiency AC or heat pump can unlock real savings — through a federal tax credit, local utility programs, and the way you finance it. The exact dollars depend on your equipment and your situation, so treat the figures below as the framework and confirm the specifics before you decide.

What is the federal 25C tax credit?

Through 2032, the federal Energy Efficient Home Improvement Credit (often called 25C) can cover 30% of the cost of qualifying high-efficiency equipment, with annual caps:

Up to $600 for a qualifying high-efficiency central air conditioner.
Up to $2,000 for a qualifying heat pump (heat pumps have their own, higher annual limit).

Your equipment has to meet specific efficiency requirements, and you claim the credit on IRS Form 5695 when you file. Because it's a tax credit, the benefit depends on your tax situation — confirm eligibility with a tax professional and current IRS guidance. We'll give you the model details and AHRI documentation you need.

Are there local utility rebates?

Yes — AEP Texas, the Valley's electric utility, runs energy-efficiency programs that can include rebates for qualifying high-efficiency HVAC equipment, usually delivered through participating contractors or program sponsors. Program names, requirements, and rebate amounts change from year to year, so check the current offers directly with AEP Texas before you count on a specific figure. We can point you to the active program when you get your estimate.

What about the newer federal rebate programs?

Two newer federal programs (commonly called HOMES and HEAR) were created to help fund energy-efficient upgrades, but they roll out state by state. As of this writing they were not yet available to Texas homeowners. Check the official Texas program status before assuming you can use them.

Don't overlook financing as a "savings" tool

Spreading the cost over low monthly payments protects your savings and lets you buy the more efficient system that costs less to run. We offer financing through Optimus with fast approval and no prepayment penalty. And our VIP plan keeps the new system efficient and the warranty valid — saving you money over its whole life.

How do I find out what I actually qualify for?

The honest answer: it depends on the equipment and your home. Book a free estimate — we'll recommend qualifying options where it makes sense and hand you the paperwork to claim what you're owed. See also what SEER2 means and our AC replacement cost guide.

Plain-language definitions — see the full HVAC glossary.

SEER2: Seasonal Energy Efficiency Ratio 2 — the current U.S. rating for how efficiently an AC or heat pump cools over a season. It replaced the old SEER scale in 2023 using a tougher, more realistic test. Higher SEER2 means lower running cost for the same cooling.
Heat Pump: An AC that can run in reverse to heat as well as cool. Because it moves heat instead of burning fuel, a heat pump is an efficient way to handle both jobs in a mild climate like South Texas.
EER2: Energy Efficiency Ratio 2 — efficiency measured at a single hot operating point (about 95°F) rather than across a season. In a place like the Rio Grande Valley, where it's hot for months, EER2 is a useful real-world number to look at alongside SEER2.
