A Guide to Common Air Conditioning Problems in Cupertino, CA Homes
Your air conditioner is a complex system. Here are some of the most common issues our Cupertino, CA technicians encounter, and what they might mean for your system.
- Your AC Won't Turn On:Possible Causes: This could be something simple like a tripped circuit breaker or an issue with your thermostat's settings or batteries. It could also indicate a more complex problem with the transformer, a safety switch, or the control board.
- Your AC is Blowing Warm Air:Possible Causes: The most common cause is a dirty air filter restricting airflow. It could also be a sign of low refrigerant due to a leak, or dirty coils that can't properly transfer heat.
- You Hear Strange Noises:Possible Causes: A high-pitched squealing could mean a problem with a belt or motor bearings. A rattling noise might indicate loose panels or debris in the outdoor unit. A loud buzzing sound could be an electrical issue with the compressor.
- Water is Leaking Around Your Indoor Unit:Possible Causes: Your AC system creates condensation, which is drained away. A leak typically means the condensate drain line is clogged, causing water to back up and overflow, which can lead to significant water damage in your Cupertino, CA home.
- Your Utility Bills Have Increased Suddenly:Possible Causes: A sudden spike in your cooling bills can be a sign that your AC is losing efficiency. This is often caused by dirty coils, low refrigerant, or leaky ductwork. A professional air conditioning cleaning can often help.If you're experiencing any of these issues in your Cupertino, CA home, it's best to call a certified professional from Zoop HVAC for a safe and accurate diagnosis.
