Is the price difference a dealbreaker?
At 1%, this gap is small enough that it's usually swallowed by normal quote-to-quote variation for furnace replacement — focus on the contractor, not the city.
Furnace replacement by type: Chattanooga vs Hendersonville
Every furnace replacement type gets its own localized price for each metro, using the same labor, climate and permit adjustments — a true apples-to-apples comparison.
| Type | Chattanooga | Hendersonville |
|---|---|---|
| Gas furnace | $3,750–$6,800 | $3,800–$6,900 |

Treat these as 2026 localized estimates for furnace replacement, not quotes from a contractor.
Furnace replacement by home size: Chattanooga vs Hendersonville
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 | Chattanooga | Hendersonville |
|---|---|---|
| 1,000 sq ft (≈45,000 BTU) | $2,900–$5,200 | $2,950–$5,250 |
| 1,500 sq ft (≈68,000 BTU) | $3,350–$5,950 | $3,400–$6,000 |
| 2,000 sq ft (≈90,000 BTU) | $3,850–$6,900 | $3,900–$7,000 |
| 2,500 sq ft (≈110,000 BTU) | $4,400–$7,850 | $4,500–$7,950 |
| 3,000 sq ft (≈130,000 BTU) | $5,000–$8,800 | $5,050–$8,900 |
| 3,500+ sq ft (≈150,000 BTU) | $5,550–$9,800 | $5,650–$9,900 |

What hvac pros earn in each metro
Roughly 60% of what you pay for furnace replacement is labor, which is why local wages explain most of the price gap. The numbers below are actual metro wages for skilled installers, sourced from BLS OEWS — not guesses.

Cheapest time for furnace replacement in either city
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.
How much should you really budget for HVAC in 2026?
An HVAC budget isn't one number — it's a set of trade-offs between sizing accuracy, efficiency tier and brand. Our editors walk through how each one moves the price.
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 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.
Get the sizing and the commissioning right and the brand debate mostly disappears. Insist on a Manual J, pick an efficiency tier your climate can justify, and pocket every incentive that still applies after the federal credits lapsed.
