How much does a furnace replacement cost in Tucson?

No one can price your furnace before seeing the house, and there’s no published Tucson figure. National cost guides give a rough frame. HomeGuide lists $3,500 to $7,500+ installed for a standard-efficiency furnace, and HomeAdvisor lists $2,823 to $6,897 for a furnace replacement, both as national figures (checked October 2026). The written quote from the pro is the number that counts for your home.

Cost depends on the equipment, the duct condition, venting, the permit and access. A written quote that lists each of those lets you compare two contractors fairly. Climate Pros Tucson doesn’t set prices. The licensed pro you’re matched with does.

Should you replace a furnace with another furnace?

Tucson’s heating load is mild: about 1,333 heating degree days a year against 3,424 cooling degree days, and fewer than 12 nights a year at or below 32F (1991-2020 normals at the airport). The AC runs far more than the furnace.

That makes a heat pump a sensible default for a Tucson-basin home. It heats and cools with one system. In Arizona, a central furnace is the main heat in 55% of homes and a central heat pump in 25% (statewide, 2020, EIA), so both are common. Gas stays an option, and Southwest Gas serves the area.

Mount Lemmon and Summerhaven are the exception. At that elevation, backup heat is a question for the pro.

Gas pack vs split system

A gas pack is a single rooftop or ground cabinet with the furnace and AC combined. A split system has an indoor furnace or air handler and a separate outdoor unit. Which you have decides what a replacement costs and how it’s done. See package unit heat pump vs gas pack and split system vs rooftop package unit.

What belongs on the quote

  • Make and model numbers for every piece of equipment.
  • The load calculation. The City of Tucson requires load and sizing calculations for new and replacement HVAC equipment.
  • The permit. City of Tucson permits are listed for furnaces, heat pumps and ACs, new or replacement, and the contractor pulls it. The City’s fee schedule, effective July 1, 2026, lists a $150 trade permit for an air conditioner or heater repair or replacement (checked October 2026), and it shows up on the contractor’s written quote.
  • Duct changes, venting, gas line, electrical and thermostat.
  • Removal of the old equipment.
  • The manufacturer warranty and any labor warranty, in writing.
  • A start-up and test.

Rebates and credits

As listed by TEP in October 2026, heat pump quality installation was eligible for up to $720 through a participating Efficient Home contractor. Confirm with TEP before you sign. The Southwest Gas 2026 Arizona rebate application lists showerheads, clothes washers and windows, and no furnace or HVAC rebate. Ask the contractor to confirm for your address. The federal 25C credit ended for installs after 2025.

When a repair is enough

If the furnace is failing but not dead, compare a repair against replacement. See furnace repair cost and signs your furnace is going out. Related: gas furnace to heat pump conversion. Service pages: furnace repair and heat pump service. Area overview: Tucson HVAC hub.
