Furnace Repair in Salt Lake City

Blowing cold air. The blower runs but there's no heat. Usually an igniter, a dirty flame sensor, or a gas valve fault.

Won't start at all. Thermostats, control boards, limit switches, or a tripped safety.

Starts then shuts off after a minute or two. Short cycling. Commonly a dirty flame sensor or a blocked flue, and sometimes a badly oversized system. The flame sensor is a cheap, quick fix.

Loud bang on start-up. Delayed ignition — gas building up before it lights. Worth looking at promptly rather than living with.

Blower runs constantly. Fan limit switch or thermostat wiring.

Weak airflow. Usually a filter nobody has changed in a while. Sometimes a failing blower motor or capacitor.

A flame sensor confirms the burner has lit. Over a season it builds up a film of residue, stops detecting the flame, and shuts the furnace down as a safety measure. The furnace isn't broken — it just can't see itself working.

It's one of the most common and least expensive furnace repairs we do.

Check the filter. A clogged filter restricts airflow and causes a surprising share of heating complaints. If it's grey and matted, replace it and see whether that fixes things.

Check the thermostat. Batteries, and that it's set to heat.

Check the furnace switch. It looks like a light switch, usually near the unit, and it gets knocked off more often than you'd think.

If those are all fine, call us.
