If your air conditioner is low on refrigerant, either the system was undercharged at installation or it leaks. If it leaks, simply adding refrigerant is not a solution. A trained technician should fix any leak, test the repair, and then charge the system with the correct amount of refrigerant. Remember that the performance and efficiency of your air conditioner are most significant when the refrigerant charge exactly matches the manufacturer’s specification and is neither undercharged nor overcharged. Refrigerant leaks can also be harmful to the environment.
If you allow filters and air conditioning coils to become dirty, the air conditioner will not work correctly, and the compressor or fans are likely to fail prematurely. Just a simple checkup now and then can prevent you from needing unsightly repairs that can cost thousands of dollars. Don’t wait to call Custom Air Systems if you need any info or advice on A/C maintenance.
Electric Control Failure
The compressor and fan controls can wear out, especially when the air conditioner turns on and off frequently, as is common when a system is oversized. Because corrosion of wire and terminals is also a problem in many systems, electrical connections and contacts should be checked out during a professional service call.
Room air conditioners feature a thermostat sensor, located behind the control panel, which measures the temperature of air coming into the evaporative coil. If the sensor is “knocked out of position,” the air conditioner could continuously cycle or behave erratically. The sensor should be near the coil but not touching it; adjust its position by carefully bending the wire that holds it in place.
When it’s humid outside, check the condensate drain to make sure it isn’t clogged and is draining properly. Room air conditioners may not drain properly if not mounted level.
