How to Troubleshoot Central Heat?

Central heat malfunctions do not necessarily always require expensive HVAC repairs. Sometimes, the central heat issues need a self-inspection, DIY solution, or less costly repair service. Failure to resolve the issue may require heating replacement in Yuma, AZ. If your heating system is performing poorly, consider following the steps to troubleshoot the central heat.

Steps To Troubleshoot Central Heat

After the heating installation in Yuma, AZ, you get hassle-free and smooth heating performance over a few years. Usually, the central heat’s condition degrades, and the furnace malfunction starts after 8 to 10 years.

If the system is poorly maintained and lacks annual professional maintenance, it can show signs of repair before the mentioned period. You will have to follow a few steps to troubleshoot your furnace system.

Air Filter

If the problems you are facing are weak air, partial heating, and poor indoor air quality, the root cause is the dirty air filter. The primary function of the air filter is to collect dirt and prevent it from entering the other parts of your furnace. It fails to do this task when it gets accumulated with dirt.

Remove the air filter. If it is reusable, clean it and place it back. If the air filter is disposable, replace it with a new one. The furnace needs filter replacement at least twice annually. The need also depends on the number of people in your house, the number of pets, and the surroundings of your location.

Fix the pilot light

The gas furnace lights the flame to provide heat. The ignitor light performs this particular task. If your thermostat is set to the heating mode and the temperature settings are also as required, but you see weak or no flame in the pilot light, check the ignitor.

Turn the gas reset valve OFF for a few minutes (ideally for 5 to 6 minutes), and turn it ON. If this doesn’t resolve the problem, there is insufficient gas, or the ignitor needs a replacement. Contact the technician to know the exact solution.


After the heating installation in Yuma, AZ, the thermostat accompanies the furnace for approximately ten years. The thermostat is responsible for the indoor temperature. If your thermostat is not working properly, reset it. When resetting didn’t help, check the circuit breaker. The breaker should not be tripped.

A blown fuse can also cause this problem. Restart the circuit breaker by flipping it down for a few minutes and switching it ON again. Also, if your thermostat works with batteries, replace the dead batteries.

Condition of air registers

The air registers need to be open for proper airflow. If it is blocked, restricted, or closed, it will hinder the furnace’s performance.

Look at the other components

After ensuring the quality check of the main components responsible for furnace performance, check the secondary components to troubleshoot your HVAC. The motor may need belt replacement.

If you sense cold patches in the radiator, bleed the radiator out. The build-up of sludge also causes radiator issues. Use a sludge remover to get rid of this problem.
