Furnace and heating repair in Tucson
Tucson heating gets little use, so problems tend to show up on the first cold night of the year. Fixr puts a typical furnace repair at $349 to $650, with a $485 national average.
How Tucson homes heat
About 51% of occupied homes in the ZIP codes we cover heat with utility gas and 44% with electricity (Census ACS 2020-2024). Gas homes usually have a furnace paired with the air conditioner. Electric homes have a heat pump or heat strips in the air handler. From 2016-2025, January at the airport averaged a low of 39.8°F.
Common problems
- Furnace won't light: a dirty flame sensor, a failed igniter, or a pilot or gas valve problem.
- Burning smell on the first run of the season: usually dust burning off the heat exchanger or strips. If it doesn't clear quickly, shut it off and call.
- Heat pump blows cool air in heat mode: often a reversing valve or the thermostat setting. Heat pumps.
- Blower runs but no heat, or heat but no blower.
If you smell gas, leave the house and call 911 or your gas utility from outside. Don't flip switches on the way out.
What it costs
Fixr's figures put furnace repair at $349 to $650, with a $485 average. Its full range runs from $66 to $2,673, depending on the part. Since the same company usually services both, it makes sense to have heating checked in fall if your system gets a spring AC tune-up.
