Your home air conditioner is a complex system. Your air conditioner depends on a wide variety of conditions to work correctly and efficiently. These conditions are designed to meet the certain “load” on the house and to have a certain amount of refrigerant to cool appropriately. Your unit is also designed to have a certain amount of airflow across the coils. When any of these things change, your system can develop problems and not be able to keep up with the cooling. If refrigerant leaks out, you will get less cooling and will need to have refrigerant added and possible leak detection performed to diagnose why the refrigerant has leaked out. If your evaporator coil freezes, performance drops and can damage the compressor until it fails, leaving you with an expensive repair bill. Almost every air conditioner has a filter upstream of the coil. As the filter does its job, it gets loaded with particles that can actually affect the efficiency and productivity of your system. If you do not change the filter regularly, the air flow of your system will be reduced and the air conditioner will stop cooling properly. Routine maintenance at the start of or before the cooling season and changing the filter monthly can leave you with a nice cool home during the summer heat. Call us if you need us:
