Understanding Your Furnace

Furnaces typically function using electricity, gas, or oil to heat air, which is then distributed throughout your home. Identifying the type of furnace you have will help you determine the correct troubleshooting steps.

Common Furnace Problems and Solutions

Furnace Not Producing Heat

If your furnace is not producing heat, start by checking the thermostat. Ensure it is set to 'heat' and the temperature is set higher than the current room temperature. Replace the thermostat batteries if necessary.

• Check the Power Supply: Ensure that the furnace is receiving power. Check circuit breakers and fuses.
• Inspect the Pilot Light: If your furnace has a pilot light, make sure it is lit. If it's out, relight it by following the manufacturer's instructions.

Furnace Cycles On and Off Frequently

This issue often stems from a dirty air filter. Replace or clean the filter to improve airflow. If the problem persists, the thermostat may be faulty, or the blower motor may need attention.

When to Call a Professional

While some furnace issues can be handled with basic DIY methods, certain situations require professional intervention. For complex problems like a faulty heat exchanger or gas line issues, contact a qualified technician. Visit technician ac for expert assistance.
