Frequently Asked Questions

If your heater is not working in your house, start with simple checks before calling for repair. The most common causes are incorrect thermostat settings, a tripped breaker, or a clogged air filter limiting airflow. Del-Air provides heating repair and troubleshooting for heat pumps, ductless mini-splits, packaged units, and thermostats, and we also offer maintenance agreements to prevent surprise outages. We service homes across West Orlando, including Winter Garden, so help is nearby.

Try these quick steps before you schedule service:

  • Set the thermostat to Heat, raise the setpoint, and replace its batteries if it has them.
  • Check the HVAC breaker and the furnace/air handler switch; reset once if tripped.
  • Replace a dirty air filter to restore airflow.
  • Make sure the outdoor heat-pump unit has clear space around it and no heavy ice buildup.
  • Note any thermostat or mini-split error codes for the technician.
  • Call a pro if breakers keep tripping, there’s a burning smell, water is pooling, or there’s no airflow.

If you smell burning or the breaker trips again, turn the system off and schedule a technician visit.
