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.

Cheapest time for full HVAC system replacement in Waco
Installers cut prices in spring and fall because job volume drops and crews sit idle — the opposite happens during a summer heat wave or winter cold snap, when a dead system forces homeowners into a full-price emergency swap.
Why full HVAC system replacement quotes vary — and how to compare them fairly
Price differences on an identical job trace back to the assumptions each contractor made; understand those and the 'expensive' bid often turns out fair.
Why a quote looks high (or low)
- One quote bundles ductwork, electrical, permit and old-unit removal; another quietly leaves them out.
- Equipment tier isn't matched — a 14.3 SEER2 bid will always undercut an 18 SEER2 one for the "same" job.
- Sizing was guessed from square footage instead of a Manual J load calculation, so the equipment is wrong.
Get an apples-to-apples bid
- Ask every bidder for the same SEER2/AFUE rating so you compare like for like.
- Confirm old-unit removal, the permit and startup testing are all included.
- Insist on a Manual J load calculation, not a square-footage guess.
- Require an itemized quote splitting equipment, labor, permit and add-ons.
Questions to ask Waco HVAC pros
Level the field before you choose — ask each bidder the same questions and watch how the answers differ.
- 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?

Budget about $200 for the HVAC permit most Waco jobs like this require — and note it already sits inside the estimate above, not on top of it.
What affects full HVAC system replacement cost the most?
Replacing the complete HVAC system — furnace plus central AC or heat pump — together. Where two homes diverge is in the details below. Your hot climate zone plays a part, but equipment/material grade, the size and complexity of the home, and local labor rates weigh in just as heavily.
How much should you really budget for HVAC in 2026?
Three factors move an HVAC quote more than anything else: how well it's sized, which efficiency tier you pick, and the brand markup. Our editors break down how they weigh each one.
The longevity case
The single biggest cost driver isn't the brand — it's correct sizing and install quality. A properly sized, well-commissioned mid-tier system with annual maintenance outlasts an oversized premium unit that short-cycles. Spend on the install, not the badge.
The efficiency-first case
In a hot-summer or cold-winter region, a higher SEER2/AFUE unit — or a heat pump — earns its premium back in lower bills, and utility and state rebates can still cut into the sticker (the federal 25C/25D credits ended Dec 2025). Run the payback math before defaulting to the cheapest box.
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.
The costly errors in an HVAC job are a bad load calculation and a sloppy install — not the logo you chose. Size it with a real Manual J, let your climate set the efficiency tier, and claim whatever rebates you still qualify for.
