About this service
Furnace repair often involves the igniter, flame sensor, gas valve, blower motor, or thermostat. A dirty flame sensor and a failing igniter are among the most common residential furnace issues.
Before requesting service, check the thermostat batteries and setting, confirm the breaker is on, and make sure the air filter isn't clogged — a dirty filter can cause the furnace to shut down for safety.
Denver's cold, dry winters make a reliable furnace essential, so addressing heating issues early matters for everyday comfort.
