Midsummer air conditioner breakdowns are inconvenient, uncomfortable and expensive. The best way to prevent a breakdown and the following issues is to schedule preventive maintenance with a qualified HVAC professional.
Low refrigerant level.
If your air conditioner was properly charged during its installation, a low refrigerant level means you have a leak. A technician can find and fix a leak, then test the repair and top of your systems refrigerant to match the manufacturer recommended level.
Drainage problems.
During periods of high humidity your condensate drain may become clogged resulting in an overflow and system shutdown. The clog can be removed with a plumber's snake. Any water damage will have to be completely dried to control and prevent the growth of mold.
Electrical control failure.
Corroded terminals/wires and loose electrical connections can prevent your system from working efficiently, or entirely even. Have a technician take a look and tighten the electrical connections, inspect the terminals and wires, and test the electrical control to ensure proper cycling.
Dust buildup.
Over time dust can build up in your air conditioner, causing the fan, motor or condenser to fail. An annual tune-up includes dust removal and between maintenance you can prevent dust build up by doing the following:
• Check your air filter monthly and replace it when it's dirty.
• Keep the area around your indoor unit free of dust.
• Hose down your outdoor unit monthly to remove debris and dirt from the coil and fins.
• Remove obstructions such as plants growth from around the unit.
Sensor Problems
Room air conditioners have a sensor that tells the unit when to cycle. If this sensor because bent or damaged, open the panel and bend it so that it's close to the coil but not touching it.
If you haven't had annual maintenance in the past year, or just want to be sure your system is running efficiently this summer,
