If your heater is not working in your house, Aire Care Mechanical Heating & Cooling recommends a few quick safety checks first, then professional service if it still won’t run. The most common causes are an incorrect thermostat setting, a tripped breaker, or a clogged air filter limiting airflow. We service homes across the Knoxville area, including Corryton, with repairs, tune-ups, and full replacements, and priority after-hours service is available.
Try these simple checks before you call:
- Set thermostat to Heat, raise the setpoint, and replace batteries if it has them.
- Confirm the furnace/air handler switch is on and reset any tripped breaker once.
- Replace a dirty filter and make sure supply/return vents are open and unblocked.
- If you smell gas, hear a CO alarm, or see scorching, leave the home and call emergency services.
If basic checks don’t restore heat, avoid repeated resets and schedule a diagnostic to prevent further damage.
