Basically a tie — focus on the contractor
This is a statistical tie on furnace replacement cost, so let contractor reputation and project timing decide, not geography.
Furnace replacement by type: Brentwood vs Nashville
Each furnace replacement option, priced separately for both metros — the same local labor, climate and permit adjustments applied per city, so you can compare like for like.
| Type | Brentwood | Nashville |
|---|---|---|
| Gas furnace | $3,800–$6,900 | $3,800–$6,900 |
| High-efficiency gas furnace | $3,400–$6,900 | $3,400–$6,900 |

Treat these as 2026 localized estimates for furnace replacement, not quotes from a contractor.

| Size | Brentwood | Nashville |
|---|---|---|
| 1,000 sq ft (≈45,000 BTU) | $2,950–$5,250 | $2,950–$5,250 |
| 1,500 sq ft (≈68,000 BTU) | $3,400–$6,000 | $3,400–$6,000 |
| 2,000 sq ft (≈90,000 BTU) | $3,900–$7,000 | $3,900–$7,000 |
| 2,500 sq ft (≈110,000 BTU) | $4,500–$7,950 | $4,500–$7,950 |
| 3,000 sq ft (≈130,000 BTU) | $5,050–$8,900 | $5,050–$8,900 |
| 3,500+ sq ft (≈150,000 BTU) | $5,650–$9,900 | $5,650–$9,900 |

What hvac pros earn in each metro
With labor making up about 60% of a furnace replacement job, wage differences between metros do most of the work here. These figures are real BLS OEWS installer wages, not modeled estimates.

Cheapest time for furnace replacement in either city
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.
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 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 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 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.
Skip the brand debate. A correctly sized system, an efficiency tier that fits your climate, and a properly commissioned install will save you more than any label ever could.
