Rebates & incentives in Alabama
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 Florence
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
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)
- Equipment tier isn't matched — a 14.3 SEER2 bid will always undercut an 18 SEER2 one for the "same" job.
- Brand, warranty length and whether startup/commissioning is included all move the number.
- One quote bundles ductwork, electrical, permit and old-unit removal; another quietly leaves them out.
Get an apples-to-apples bid
- Insist on a Manual J load calculation, not a square-footage guess.
- Get at least three written bids before you sign.
- Confirm old-unit removal, the permit and startup testing are all included.
- Ask every bidder for the same SEER2/AFUE rating so you compare like for like.
Questions to ask Florence HVAC pros
The only honest way to compare is to hold every quote to one checklist. Start with these.
- 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. Price swings mostly come down to equipment or material grade, the size and complexity of the home, local labor, and the hot climate zone.
How much should you really budget for HVAC in 2026?
What you pay for HVAC hinges less on the badge than on how the quote is built — the load calculation behind it, the efficiency tier, and the markup. Our take on where each one lands.
The budget-first case
In a temperate region the smart move is to size the job correctly with a Manual J and take the base efficiency tier. A system that spends most days coasting can't recover the cost of a high-SEER2 compressor, because the savings only show up under heavy load you don't put on it. Match the equipment to how little you actually run it, not to the brochure's top number.
The efficiency-first case
High runtime changes the math. In a demanding climate the extra efficiency of a heat pump or a top-tier SEER2/AFUE unit gets paid back month after month on the utility bill, and state and utility incentives can shave the upfront figure further now that the federal 25C/25D credits have expired. Price the lifetime bills, not just the tag, before you default down.
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.
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.
