Yes, Las Vegas has a heating season
It is short, but it is real: from late November through February, valley nights regularly fall into the 30s, and a working heater is the difference between a cold house and a comfortable one. Valley homes heat with two technologies — gas furnaces (the majority of older housing stock) and heat pumps (increasingly common in newer construction and high-efficiency upgrades). This page covers repair for both.
Why furnaces fail here: the dormancy problem
Las Vegas furnaces have an unusual life: they sit idle from March through November, then get asked to fire up perfectly on the first cold night. That long dormancy is what kills them — igniters weaken and crack with age rather than use, dust and spider webs foul burners and flame sensors, and control board connections corrode. It is why so many furnace failures happen on the same first cold snap of the year, valley-wide. A fall tune-up catches most of it for less than a repair call.
Common furnace repairs
- Hot surface igniter — the most common failure; the furnace clicks but never lights
- Flame sensor — burners light, then shut off after a few seconds; usually just needs cleaning
- Inducer motor — the draft fan that clears combustion gases; failure means no ignition
- Control board — the brain; error codes on the LED point the diagnosis
- Limit switch — tripped by overheating from dirty filters or weak blower airflow
Heat pump heating repairs
Heat pumps run the same refrigeration circuit as your AC, reversed. Heating-mode failures are usually the reversing valve (stuck in cooling mode), defrost controls (outdoor coil ices up and never clears), or low refrigerant charge affecting both seasons. Because the same compressor does both jobs, a heat pump failure in December often traces back to a weakness that showed up during summer cooling.
Carbon monoxide: the check that matters most
Every gas furnace visit should include a combustion safety check. A cracked heat exchanger can leak carbon monoxide into the airstream — colorless, odorless and dangerous. Symptoms of concern: soot around the furnace, a yellow or flickering burner flame (should be steady blue), or family members with unexplained headaches and nausea when the heat runs. Every home with gas appliances needs working CO detectors on each floor. A cracked heat exchanger is not a repair — it is a replace decision, full stop.

Frequently asked questions
Do I really need heating repair in Las Vegas?
Yes — desert winters are colder than visitors expect. December and January nights regularly drop into the 30s, and overnight lows below freezing happen most winters. A dead furnace on a 35°F night is a real problem, especially for young children and elderly family members.
What are the most common furnace repairs in Las Vegas?
Hot surface igniters and flame sensors top the list — both are wear items. Inducer motors, control boards and limit switches follow. Valley furnaces sit idle eight-plus months a year, and that long dormancy is hard on igniters and lets dust foul flame sensors — many “furnace died” calls are a dirty sensor, a fast and inexpensive fix.
Is a gas smell from the furnace an emergency?
Yes. Leave the house without touching switches, and call the gas utility’s emergency line from outside. Once the utility clears the home, an HVAC technician can repair the furnace-side cause. Do not run the furnace again until both have checked it.
Should I repair or replace my furnace?
The $5,000 rule applies: age times repair cost. Furnaces last longer in Las Vegas than in cold climates because of low run hours — 20-plus years is common — so repair usually makes sense unless the heat exchanger is cracked, which is a replace decision for safety reasons.
How much does furnace repair cost in Las Vegas?
Common repairs run $150–$1,100: igniters and flame sensors at the low end, inducer motors and boards in the middle. The diagnostic visit is $75–$200. Sourced ranges are on the cost page.
Do you repair heat pumps in heating mode too?
Yes. Heat pumps handle both seasons in one unit; heating-side failures are usually the reversing valve, defrost board or sensors. “Blowing cold air in heat mode” and “outdoor unit frozen in winter” are the classic heat pump heating complaints.
