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

The right first steps when a home heater isn’t working are to verify power, thermostat settings, and airflow before calling a technician. Most no-heat calls start with a simple control issue or a tripped breaker, not a failed heater.

Our team services homes throughout the Space Coast, including the Merritt Island area.

Try these quick checks before you schedule service:

• Confirm the thermostat is on Heat, set above room temperature, and has fresh batteries if applicable.
• Check the HVAC breaker and the indoor unit’s power switch; if a breaker trips again, stop and call.
• Replace a dirty air filter and make sure supply and return vents are open.
• Look for water in the drain pan or a tripped float switch; clear standing water if safe.
• For heat pumps, make sure the outdoor unit is clear of debris and not iced over.

If you smell gas, hear arcing, or see smoke, shut off power, leave the home, and contact emergency services first.
