How much should this gap actually matter?
That 4% gap is small — for furnace replacement it's usually less than the spread between two local contractors' quotes, so the metro matters far less than who you hire and when you buy.
Furnace replacement by type: Birmingham vs Florence
We localize each furnace replacement type separately for both metros, applying the same labor, climate and permit adjustments each time, so you're comparing like for like.
| Type | Birmingham | Florence |
|---|---|---|
| Gas furnace | $3,550–$6,400 | $3,350–$6,100 |
| High-efficiency gas furnace | $3,150–$6,400 | $3,000–$6,100 |
| Electric furnace | $2,000–$4,250 | $1,900–$4,050 |
These are 2026 planning figures for furnace replacement, localized to each city — not formal quotes.
Furnace replacement by home size: Birmingham vs Florence
Furnace cost scales with the heating capacity (BTU) your home needs — roughly 40–45 BTU per square foot in a mixed climate. Larger homes need a bigger unit and more ductwork.
| Size | Birmingham | Florence |
|---|---|---|
| 1,000 sq ft (≈45,000 BTU) | $2,700–$4,850 | $2,600–$4,650 |
| 1,500 sq ft (≈68,000 BTU) | $3,150–$5,600 | $3,000–$5,350 |
| 2,000 sq ft (≈90,000 BTU) | $3,600–$6,500 | $3,450–$6,200 |
| 2,500 sq ft (≈110,000 BTU) | $4,150–$7,400 | $3,950–$7,050 |
| 3,000 sq ft (≈130,000 BTU) | $4,700–$8,300 | $4,450–$7,900 |
| 3,500+ sq ft (≈150,000 BTU) | $5,250–$9,200 | $5,000–$8,750 |

Cheapest time for furnace replacement in either city
HVAC demand collapses in the mild shoulder seasons, so installers discount to keep crews busy. The most expensive time to buy is during a heat wave or cold snap, when a dead system forces a full-price emergency replacement.
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 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
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.
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.
If there's one takeaway, it's this: sizing and install quality decide whether an HVAC system performs, not the badge on the box. Get the load calculation right, match efficiency to climate, and take the rebates on offer.

Should I choose where to live based on furnace replacement cost?
That would be a stretch. $200 is a one-time difference, not an ongoing one, and off-season buying plus apples-to-apples bids in Birmingham can close a good chunk of it. What matters more long-term is energy costs, climate and the condition of the home.
