Additional furnace replacement costs to budget for
Treat them as possibilities, not certainties — the ones that reach your quote follow your property's age and setup.

| Gas line run or upgrade | $250 – $800 |
| Chimney liner (for high-efficiency venting) | $600 – $2,500 |
| Smart thermostat | $150 – $500 |
Typical national add-on ranges; confirm locally during your quote.
What's included
- The furnace unit and burner assembly
- Removal and disposal of the old unit
- Installation labor and basic ductwork connections
- Thermostat connection and system startup/testing
What affects the cost
- Condition of existing ductwork and venting
- Fuel type (gas vs electric) and AFUE efficiency rating
- Heating capacity (BTU) needed for your square footage
- Whether a chimney liner or new gas line is required
Ways to save on furnace replacement in Florence
- Look for utility rebates on high-efficiency models
- Get at least 3 quotes — installed prices vary widely
- Right-size the unit; oversizing wastes money and cycles hard
- Schedule in the off-season (spring/summer) for better rates
How long does furnace replacement last in Florence?
Gas furnaces typically last 15–20 years; well-maintained units can reach 30.
An annual tune-up keeps efficiency up and protects the warranty.
Signs you need furnace replacement in Florence
- The furnace is 15+ years old (near or past its service life)
- Heating bills keep climbing despite no change in usage
- Some rooms are warm while others stay cold (uneven heating)
- Frequent repairs — you've called for service more than once or twice recently
- Banging, rattling or screeching noises on startup
- A yellow or flickering burner flame instead of steady blue (have it checked immediately)
- More dust, dryness, or a stale smell when the heat runs
Repair or replace in Florence?
Repair if…
- The unit is under ~10 years old and otherwise efficient
- The fix is a single inexpensive part (igniter, flame sensor, capacitor)
- It's still under manufacturer warranty
Replace if…
- It's 15+ years old and needs a major part
- The heat exchanger is cracked (a safety issue — replace, don't repair)
- The repair costs more than about half of a new system
- It's an 80% AFUE unit and your fuel bills are high in a cold climate
Rebates & incentives in Alabama
Most 2026 rebates reward switching to a heat pump, not a like-for-like gas furnace. Replacing a gas furnace, your savings are mainly utility efficiency rebates (high-AFUE models) — but pricing out a heat pump often qualifies you for far larger 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 furnace replacement in Florence
Crews are busiest — and priciest — exactly when it's hottest or coldest, since that's when systems fail under load. Book in the mild months and you're negotiating from a position of choice, not a broken furnace.
Why furnace replacement quotes vary — and how to compare them fairly
One bid high, one low, same house? The variable is scope. Here's what pushes the figure up or down and how to get quotes you can actually compare.
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.
- Sizing was guessed from square footage instead of a Manual J load calculation, so the equipment is wrong.
Get an apples-to-apples bid
- 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.
- Get at least three written bids before you sign.
Questions to ask Florence HVAC pros
Quotes only compare cleanly when every bidder is pricing the same work — put these to each of them before you commit.
- 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?
Furnace Replacement in Florence
How much does furnace replacement cost in Florence, AL?
Most Florence homeowners pay around $4,850 for furnace replacement, though 2026 quotes stretch from $3,450 to $6,200. The figure is adjusted for local labor rates, hot-climate factors and permit fees.

Do I need a permit for furnace replacement in Florence?
A HVAC permit is standard in Florence for this kind of work, at roughly $175. You won't need to add it on top of the estimate above — it's already there.
What affects furnace replacement cost the most?
Here's the short version: replacing a residential furnace, including the unit and installation labor. 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?
Get the sizing wrong or the efficiency tier mismatched to your climate, and the price drifts fast in either direction. Below, a look at how those choices — plus brand markup — shape the real number.
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 longevity case
The most expensive variable on the quote isn't the logo — it's whether the system is sized right and installed well. Oversize a premium unit and it short-cycles, wears fast and underperforms; commission a correctly sized mid-tier one and keep up the annual service, and it simply lasts longer. Spend on the installation, not the badge.
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.
Match the efficiency tier to your climate, insist on a real load calculation, and stack every rebate you qualify for. The expensive mistakes are wrong sizing and a rushed install — not picking the "wrong" brand.
