Nashville Furnace Repair

If your furnace turns on but shuts off quickly, it could be due to a dirty flame sensor, a clogged filter, or an overheating issue. A faulty thermostat or a malfunctioning pressure switch may also cause the system to short cycle. Regular maintenance can help prevent these problems and keep your furnace running smoothly.

Check to make sure your thermostat is set correctly and that the gas supply is on. If the pilot light is out or the ignition system fails, the furnace won’t produce heat. A professional technician can diagnose the issue and repair or replace the faulty components.

A loud banging sound when your furnace starts could mean delayed ignition, which happens when gas builds up before igniting. Expanding and contracting ductwork or a dirty burner can also cause loud noises. If you hear repeated banging, it’s best to have a professional inspect your system for safety.

Condensation leaks are common in high-efficiency furnaces with clogged drain lines or faulty pumps. A heat exchanger issue or a malfunctioning humidifier can also cause water to pool around your unit. If you notice leaks, turn off the system and call a professional to prevent further damage.

Signs of a failing blower motor include weak airflow, unusual noises, or the system not turning on at all. If your furnace runs but doesn’t distribute warm air properly, the motor may be overheating or wearing out. A technician can test the blower and determine if it needs repair or replacement.

A burning smell when you first turn on your furnace is usually dust burning off the heat exchanger, which should go away after a few minutes. However, persistent burning odors could indicate electrical issues, overheating components, or a clogged filter. If the smell doesn’t fade quickly, shut off the system and have it inspected.

Yes, a dirty air filter can restrict airflow, causing your furnace to overheat and shut down. It can also put extra strain on the blower motor, leading to higher energy costs and potential breakdowns. Replacing your filter regularly is a simple way to prevent unnecessary furnace repairs.

If your furnace keeps tripping the breaker, it could be due to an overloaded circuit, a shorted wire, or a failing motor. A dirty filter or blocked airflow can also force the system to work too hard, drawing excess power. If resetting the breaker doesn’t solve the problem, call an HVAC professional to inspect your furnace.
