Q: How do I maintain and care for my furnace?

A: Every heating system is different so be sure to follow the guidelines and recommendations found in your manufacturer’s manual. Here are some general suggestions: Clear out any clogs or blockages in the filters and drains monthly. Always have a carbon monoxide detector in your home to ensure safety and have a professional HVAC technician complete an annual maintenance check-up once a year.


Q: My thermostat isn’t working. What do I do?

A: Try changing the batteries, rebooting, or turning the breaker switch off for 30 seconds before turning it back on.


Q: How do I change a dirty furnace filter?

A: An old filter can drive up your energy bill and cause a host of other issues. Remember to change your filter often; length varies by your unit.


Q: My furnace isn’t igniting. How can I fix it?

A: Check the power, turn off the gas to the furnace, and remove the front panel to find the ignition sensor (usually near the burners.) Take a photo to remember how it’s attached before removing the ignition sensor. Rub it with steel wool to remove residue, being careful to not damage it. Then put it back exactly as you found it and replace the panel before turning the gas back on. If you don’t feel comfortable trying this, call Air Pros at (843) 225-6052.


Q: Why does my furnace keep tripping the breaker?

A: If your furnace keeps tripping the breaker or blowing the fuse when the heat kicks in, it’s most likely an electrical issue. To keep you and your family safe, call Air Pros at (843) 225-6052 to diagnose the cause.
