What Should I Do If My Heater Is Not Working in My House?

Start with a few quick checks, then book service if it still won’t run. We offer a $89 HVAC Repair Diagnostic with a Next Day Guarantee, and the diagnostic charge is waived with service. This applies to homes in Phoenix and surrounding areas.

Quick checks:

• Set thermostat to Heat and 3–5°F higher.
• Replace/clean the air filter.
• Check the breaker and furnace switch.
• Ensure vents are open and returns clear.
• For gas units, confirm the gas valve is on and the pilot/ignition works.
