Why Isn't My HVAC System Cooling My Home Properly?

HVAC Technician Troubleshooting HVAC System

When your HVAC system lets you down in the middle of a hot summer day, your first instinct is to put your troubleshooting/problems solving skills to the test. However, there are certain situations in which it is better to wait for professional help.

If you feel confident in your skills and handiness, and you have some basic understanding of how the HVAC system works, you can undertake simple tasks like duct cleaning or filter changing. However, you should leave any problems related to the coolant or the electrical system to professionals.

Here are the most common scenarios related to HVAC system failure in cooling homes properly and the troubleshooting and problem solving steps that may help:

  1. The air condenser does not run: Make sure it is plugged in and check to see if the circuit breaker is tripped or the fuse is blown. Restore power and check again. Check the thermostat by lowering the temperature by five degrees and observing it until the unit kicks on. When it does not, the reason could be a compressor or motor malfunction that should be dealt with by professionals.
  2. Improper air cooling: Lower the thermostat temperature by five degrees and wait for improvements. If there are none, the evaporator could be dirty. Clean it and leave it running for a couple of hours. No improvements could mean your HVAC system is improperly sized.
  3. Unit is running but not cooling the air: The thermostat should be your starting point. The condenser is your next best guess. It could be blocked or dirty and in need of cleaning or blockage removal. When all of these fail, the compressor or the lack of refrigerant is to blame, but you should leave the matter to professionals.
  4. Air unit going on and off repeatedly: The cause could be a blocked or dirty condenser or dirty evaporator. If the cleaning process provides no results, a professional intervention should be scheduled.
