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 Plano
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
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.
- 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.
Get an apples-to-apples bid
- Get at least three written bids before you sign.
- Insist on a Manual J load calculation, not a square-footage guess.
- Confirm old-unit removal, the permit and startup testing are all included.
- Require an itemized quote splitting equipment, labor, permit and add-ons.
Questions to ask Plano HVAC pros
A fair comparison starts with identical questions. Ask each contractor the following before anything gets signed.
- 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?

What affects full HVAC system replacement cost the most?
Here's the short version: replacing the complete HVAC system — furnace plus central AC or heat pump — together. What moves the price most: equipment or material grade, your home's size and complexity, local labor rates, and the hot climate zone.
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
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 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 budget-first case
Size the system to your home with a Manual J calculation and buy the standard efficiency tier (80% AFUE / 14.3 SEER2). In a mild climate the cheaper unit pays off because you rarely run it hard — paying for premium efficiency you won't use is the most common way to overspend.
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.
