The most common reasons a home heater stops working are thermostat issues, power loss, a clogged air filter, blocked vents, or ignition/pilot problems. Dirty flame sensors, failed blower motors, or safety shutoffs can also stop heat. In the Denver area, we offer same-day and 24/7 emergency heating service. Routine maintenance helps prevent breakdowns.
Quick checks:
- Set thermostat to Heat and replace batteries.
- Ensure the furnace switch and breaker are on.
- Replace a dirty filter and clear supply/return vents.
- If you smell gas, leave and call for help.
