Here are the most common causes…
-Your thermostat is set to “Heat” instead of “Cool”
-Your fan is set to “On” instead of “Auto”
-Your outside compressor/condenser is clogged. (the box shaped unit located outside)
How to fix:
1. Ensure your thermostat is set to “cool.”
2. Make sure the fan mode is set to “auto.”
3. Clean the compressor/condenser.
How to clean your HVAC Compressor/Condenser
Rinsing off the compressor/condenser with a garden hose is the best way to clean the unit. Use a gentle flow of water, do not use high pressure. If you do not have a hose, use a broom or vacuum to remove visible dirt and debris from the outdoor compressor unit. Trim any bushes, branches, or shrubs that could be restricting airflow near your compressor. The aluminum fins you see behind the casing of your compressor/condenser can be easily bent or damaged. When cleaning the unit, use care and caution to not damage the fins.
Additional possible problems
1. Compressor/Condenser has failed or broken
2. Low refrigerant. Leaks are common in older systems.
3. Dirty AC Filter. Change the filter and re-test.
If you have low refrigerant/Freon levels, you will need to call a qualified HVAC company to test and refill. It is unlikely you will be able to do this yourself. It is also important to turn off your HVAC system. It is not a good idea to run your HVAC when experiencing these symptoms, because you may increase the chances of damaging the unit.
