Rebates & incentives in Texas
The largest 2026 HVAC incentives target heat pumps; other equipment mainly qualifies for utility efficiency rebates.
The federal 25C tax credit (up to $2,000 for heat pumps; $600 for high-efficiency AC or furnaces) and the 25D credit ended December 31, 2025 under the One Big Beautiful Bill Act — neither is available for 2026 installs. The remaining federal help is the IRA Home Electrification & Appliance Rebates (HEAR): up to $8,000 toward a heat pump for households under 150% of area median income, paid at point of sale where a state has launched its program.

A furnace or AC that dies mid-heat-wave gets replaced at whatever the on-call crew charges. One that gets swapped in April or October gets a competitive, unhurried quote instead.
Why full HVAC system replacement quotes vary — and how to compare them fairly
Two contractors can price the same job thousands apart. Almost always it's the scope each assumed — here's what drives the gap and how to close it.
Why a quote looks high (or low)
- Sizing was guessed from square footage instead of a Manual J load calculation, so the equipment is wrong.
- Equipment tier isn't matched — a 14.3 SEER2 bid will always undercut an 18 SEER2 one for the "same" job.
- One quote bundles ductwork, electrical, permit and old-unit removal; another quietly leaves them out.
Get an apples-to-apples bid
- Require an itemized quote splitting equipment, labor, permit and add-ons.
- Insist on a Manual J load calculation, not a square-footage guess.
- Confirm old-unit removal, the permit and startup testing are all included.
- Get at least three written bids before you sign.
Questions to ask Rockwall HVAC pros
Before you pick, make each contractor answer the same things — gaps in their replies tell you as much as the price.
- 1Did you run a Manual J load calculation to size the system, or estimate from square footage?
- 2What AFUE/SEER2 rating is this unit, and what's the payback vs. the next tier up?
- 3Is removal of the old equipment, the permit, and startup testing included in the quote?
- 4Will my existing ductwork and venting work as-is, or is repair/resizing needed?
- 5What's covered under the labor warranty vs. the manufacturer's parts warranty?

How much should you really budget for HVAC in 2026?
Ask five contractors for an HVAC quote and you'll get five different numbers — usually because they disagree on sizing, efficiency and equipment tier. Here's how our editors think through those trade-offs.
The efficiency-first case
Where you face brutal summers or hard winters, a higher SEER2/AFUE system or a heat pump runs enough hours to claw back its premium through lower bills — and utility or state rebates can still trim the sticker even though the federal 25C/25D credits closed at the end of 2025. Do the payback arithmetic before you reach for the cheapest box on the lot.
The longevity case
Brand is a footnote; sizing and install quality write the story. A right-sized mid-tier system that's properly commissioned and serviced once a year will outlive an oversized premium unit that short-cycles itself to an early grave. Put the money into the crew and the setup rather than the nameplate.
The budget-first case
Run a Manual J load calculation, then buy the standard tier — 80% AFUE, 14.3 SEER2 — and stop there. Where summers are short and winters are gentle, the equipment idles most of the year, so premium efficiency never gets enough runtime to earn back its price. Paying for SEER2 you'll rarely tap is the classic way a mild-climate homeowner overspends.
Climate decides the efficiency tier; a proper load calculation decides everything else. Nail both, stack the rebates you can, and you've sidestepped the two mistakes — wrong size, rushed install — that actually inflate the lifetime cost.
