Basic Troubleshooting of HVAC Systems

Although most problems related to HVAC systems require professional intervention, there are some which can be fixed with minor troubleshooting. It is important that you are knowledgeable about the particular type of HVAC system present in your home so that you can easily determine the exact location of the problem before deciding to call in the big guns. That being said, here is what you should do when a problem arises on your HVAC system:

First, turn off and unplug your HVAC system before you begin with the troubleshooting. After which, thoroughly check the radiators and pipes to ascertain that they slope back to the boiler. When your HVAC system produces a hammering sound and is not heating properly, then its slope connection must be corrected.

If you suspect leaking due to repeatedly low water levels in your system, then the best thing to do is to close the water valve, and monitor your HVAC unit for several days. In the event that the unit’s water level continuously drops even if you have already closed the valve, immediately seek the help of a professional HVAC technician.

Gently touch the expansion tank to examine the amount of air present inside. A good indication that it is functioning properly is when the lower portion of the tank feels warmer than the top. However, if the tank feels hot all over, then it means that you need to drain it because it is already filled with water.

If you hear a hissing sound in your HVAC system, open the air vent valve, with aid of a screwdriver, to remove the trapped air inside the radiator. After that, close the vent and re-open the unit to check if the hissing sound is gone.

In case your unit requires serious and extensive ventilation, air-conditioning or heater repair, it is best that you hire the services of an experienced Atlanta HVAC technician to ensure that the problem would be properly addressed.
