Heater Not Working in Las Vegas: Furnace and Heat Pump Fixes and Costs

Updated 2026-11-05 · For Las Vegas homeowners

Las Vegas winters are short, which is exactly why heaters fail on the first cold night: they have sat unused since March. Most of the fixes are small.

Gas furnace: the usual suspects

Heat pump: different symptoms

Many newer homes in the northwest and southwest heat with a heat pump, the same outdoor unit that cools. If it cools fine but will not heat, the reversing valve or its control is a common cause ($400 to $1,000). Mild warm air that feels weak is normal for a heat pump on a cold night; ice on the outdoor coil that never clears is not.

Smells and noises

A dusty burning smell for the first few minutes of the season is normal. A smell that persists, a rotten-egg gas smell, or a carbon monoxide alarm means shut it off and call. Every gas-heated home should have a CO detector.

What to ask

Whether the technician services your kind of system (gas, heat pump, or a dual-fuel setup), and whether a fall tune-up is included in a maintenance plan, since most of these failures are caught then.
