What Are Common Reasons My Heater Is Not Working in My House?

Common heater failures usually come from thermostat settings or a power/breaker issue. A clogged air filter can trip safety switches and stop heat. Gas furnaces often fail from a bad igniter or dirty flame sensor. Boilers may stop heating due to air in lines, low system pressure, or a stuck circulator. Heat pumps can stop in cold snaps from an iced outdoor unit or control faults. We provide same-day diagnostics and repairs in Colorado Springs, Monument, and nearby.

Quick checks:

• Set thermostat to Heat and 2–3°F higher.
• Replace a dirty filter.
• Check furnace switch and breaker.
• Clear snow/debris from outdoor unit.
