Furnace Replacement Cost in Tampa Bay

The headline price for a furnace replacement is only part of the story in Tampa Bay. A handful of site conditions can swing your final invoice by several thousand dollars in either direction, and most of them have nothing to do with the furnace itself.

If your home has never had natural gas service, running a new gas line from the meter to the air handler closet adds $25 to $42 per linear foot installed, including trenching, pipe, fittings, leak testing, and the gas company tie-in. A typical Tampa run is 25 to 60 feet, so plan on $1,500 to $3,500 just for the line. Homes on propane need a tank set, regulator, and stub-up, which runs $900 to $1,800 on top of the furnace itself.

Venting changes are the next big swing. If your old atmospheric furnace vented through a B-vent up the chimney chase, switching to a modern 90%+ AFUE direct-vent unit means cutting two PVC penetrations through the wall, sealing the old chase, and pitching condensate properly. That swap typically adds $800 to $2,400 versus a like-for-like replacement.

Permit and inspection fees vary by county. Hillsborough County mechanical permits run $175 to $295 for a furnace swap. Pinellas County is $195 to $345. Pasco County tops out around $395 once plan review and re-inspection fees are stacked. We pull every permit ourselves, so the price you see on the quote is the price you pay.

Old equipment removal, haul-off, and refrigerant recovery on a paired AC system typically runs $150 to $400 depending on access. Heat strip backup for a heat pump replacement may require a 60-amp double-pole breaker upgrade and 8-gauge wire pull at $300 to $750. Condensate drains routed through finished ceilings or walls cost more than garage installs because of drywall patching. Attic installs run roughly 15% to 25% higher than garage or closet locations because of physical labor and safety platforms.

Heads up on R-454B refrigerant: the federal phase-down of R-410A starting January 2026 means new heat pump systems use the new refrigerant, and the equipment itself runs about 8% to 12% higher than 2025 R-410A pricing. We carry both during the transition window.

The sticker price is rarely what you actually pay. Stacking incentives correctly can knock thousands off a furnace or heat pump replacement, but the paperwork has to be filed at install, not after. That is on us, not on you.

Federal 25C Energy Efficient Home Improvement Credit pays 30% of the project cost up to $2,000 per year on heat pumps that meet CEE Tier 1 efficiency. Most of the Goodman and Daikin variable-speed systems we install qualify. The credit runs through 2032 and is claimed on IRS Form 5695 with your tax return. We provide the AHRI certificate and the manufacturer efficiency documentation at install so your CPA has everything in hand.

TECO Energy rebates run $200 to $1,000 on heat pumps rated 16 SEER2 or higher, with bigger rebates for variable-speed inverter systems. Duke Energy runs a similar program with comparable amounts. We submit the rebate application directly so you do not have to chase TECO or Duke.

For income-qualified households, the Inflation Reduction Act HEEHRA program (High-Efficiency Electric Home Rebate Act) layers additional point-of-sale rebates of up to $8,000 on heat pump installs. Florida is rolling this out through DEO in phases. We track eligibility windows and apply on your behalf when you qualify.

On financing, we partner with GreenSky and Wisetack. GreenSky offers 0% APR promotional plans for 12 to 18 months on qualified buyers and longer fixed-rate plans up to 144 months for budget-friendly monthly payments.
