AC Troubleshooting

Even homeowners who keep up with regular AC maintenance may experience air conditioning issues. Fortunately, many common issues can be fixed with some simple tricks, including:

My Thermostat Is Blank

A blank thermostat screen makes it difficult to control your home’s temperature. The first step is to check to see if the unit needs new batteries. If this isn’t the cause of the issue, we recommend checking the condensate overflow safety reservoir. This pan is located at the air handler and can trip the safety switch if it’s full of water. Homeowners can restore function by suctioning the water out. 

A tripped breaker is another common issue. Look for a switch halfway to the OFF position on your electrical panel. Reset it by moving it all the way to OFF and then back to ON.

My AC Unit Isn’t Cooling

An AC unit that isn’t cooling is a major inconvenience. You can attempt to restore your system by checking for common issues. Start by confirming that your thermostat is working and set to COOL with a desired temperature lower than the current temperature.

The fan should also be set to AUTO. Then, check if your air filters need to be replaced or if the breaker is tripped. Finally, check the air handler to see if it’s frozen. If it’s cold and sweating, turn the system off for four to five hours to allow it to defrost.

One Room Is Warmer Than the Others

There are several reasons why one room in your home may be warmer than another. Temperature fluctuations can occur with reduced airflow, so confirm that your air filters aren’t clogged. You should also check that the supply-air and return-air grilles in the room are fully open and not blocked by furniture or decor. 

For homeowners with zoned cooling systems, the issue could be the thermostat settings for that specific zone. However, there’s also a chance that the temperature issues aren’t AC-related. The excess heat could also be due to gaps in doors or direct sunlight coming through the windows. 

None of the Above Suggestions Have Fixed My AC

If these tricks don’t restore your system, you may need professional AC repairs. Until an expert can handle the issue, you can stay cool by opening windows, using fans, or staying in shaded areas of your home. If the heat is unbearable or unsafe, consider temporary alternative accommodations.

The technician was on time, polite, professional, and thorough. He explained what he was doing and went beyond simply correcting the problem by making sure the system was working properly. I have used Del-Air before and they don’t disappoint.
