Easy Fixes For Common HVAC Issues

August 23, 2023

Every now and then, the HVAC system will show signs it’s not working properly. At this point, homeowners can choose between making simple DIY repairs or calling in a professional technician for HVAC services in Kansas City. For tech-savvy homeowners, here are some easy fixes for common HVAC issues.

Replace the filter

The air filter is the primary cause of issues with the air conditioning or heating system in your home. If it’s clogged, the system has a harder time passing air into the home, thereby increasing wear and tear and leading to premature breakdown. Air filters should be replaced once every three months, or at the beginning of each season.

Replace thermostat batteries

The thermostat is another important component of the HVAC system that affects the entire system. If the batteries are dead, the thermostat will stop sending signals to the HVAC system and your home won’t be cooled or heated to your desired temperature.

Run a power test

You can run a simple power test by setting the thermostat to “fan” mode. If the fan doesn’t turn on, the furnace may not be receiving power. In this case, you’ll need to inspect the furnace.

Check furnace codes

New furnaces have fault codes that correlate to a specific type of problem. Look for codes or flashing lights and consult the owner’s manual to identify the problem.

Check the circuit breaker

A tripped breaker can cut off power to the HVAC system. Flip the breaker back to the “On” position to turn on the HVAC system.

Clean the igniter

Hot surface igniters can become covered in dust. Use a straw to blow air at the igniter without removing it. Avoid touching the igniter because it breaks easily.

Inspect the condensate pump

If the condensate pump isn’t running, reset the GFCI outlet that powers it. If this doesn’t turn the pump back on, you may need to replace the pump.

Check the safety switch

If the furnace cover panel is removed or even slightly ajar, the system may automatically activate a safety switch. Make sure the panel is fully closed.

Unblock registers

If you have furniture blocking air vents and registers, the HVAC system will not be able to properly cool or heat a room. Move furniture and heavy drapes out of the way so that airflow isn’t restricted.
