Signs That Your Air Conditioner May Need Repairs

As the sun reemerges and temperatures start to heat up in San Mateo, CA, it is clear that summer is here! You’ll want to be certain that your air conditioner is ready to keep you comfortable all summer long. But how do you know if it needs some TLC? If you experience any of the following symptoms, your air conditioner is probably in need of repair:

Not Cooling/Producing Warm Air

If the air passing into your vents isn’t as cool as it once was, your system is working overtime to keep temperatures comfortable. It may be caused by various factors, including leaking or low refrigerant, condenser problems, and duct leakage.

Insufficient Airflow

Your fan, which is in charge of moving all the beautiful, cold air into the ductwork, will contribute to various problems that can drastically reduce airflows, such as a dirty air filter, a broken blower engine, or a defective fan control board.

Leaking Water

If you detect a leak, the device can have a clogged or defective condensate drain, which requires immediate attention.


When most air conditioners start-up and shut down, they make a low-level sound. However, noisy, abrupt, or unexpected noises may indicate serious issues with your cooling system.


Weird odors may be caused by various problems, including pest penetration, burned-out wire insulation, and mold growth inside. Take care of these as soon as possible to ensure your family’s welfare.

High Utility Bills

Your air conditioner is the most energy-intensive appliance in your house. If it was working well last season, but your electricity costs have increased this year, it is a clear sign that your cooling system needs to be inspected.
