Furnace repair

Furnace won't heat

If the furnace won't heat, run the same safe checks we already tell Denver metro homeowners: thermostat on heat and set above room temperature, a fresh filter, and vents open and not blocked. If it still won't fire, it's a service call — see the city pages below.

Safe checks before we roll

  1. 1

    Thermostat

    Set it to heat, then set the temperature above the room. If it isn't calling for heat, the furnace won't start.

  2. 2

    Fresh filter

    A clogged filter can starve the unit and trip a limit. Swap it if you have a spare.

  3. 3

    Vents

    Keep supply and return vents open and not blocked by furniture, rugs, or boxes.

When to shut it down

If it is still cold, there is a weird smell, or the breaker trips, shut it down and get a pro. Do not open panels.

How the visit works

We diagnose first, then give a plain-language finding. Repair happens only with the homeowner's OK.
