Most no-heat issues come from a few basics: wrong thermostat settings, tripped breakers, a clogged filter stopping airflow, ignition or flame-sensor faults, or a failed blower motor or safety control. We service furnaces, heat pumps, and boilers across Denver, Golden, and nearby.
Quick checks:
- Set the thermostat to Heat and raise the setpoint.
- Replace a dirty filter.
- Verify the furnace switch and breaker are on.
- Open return and supply vents.
- If you smell gas, leave and call your utility.
