Air conditioners are hard-working appliances and part of this is due to the way that the AC functions. Comfort systems such as the HVAC (heating, ventilation and air conditioning) system use a condenser unit to compress a chemical refrigerant. Compressing the refrigerant causes it to change state and this change of state allows the refrigerant collect heat. Heat transfer is possible because changing the state of the refrigerant lowers its temperature, so it is colder than the air that surrounds the evaporator coil. Unfortunately, this step in the cooling process can strain the compressor unit and force the need for Residential Air Conditioning Repair in Covina CA.
Air conditioner systems generate condensation as a byproduct of the cooling process. By itself, this would not be a problem as long as the moisture can be drained off. However, the constant movement of air through the appliance will bring dust into the environment. This can be a larger problem than many people think because the dust and moisture mix together and the resulting muck sticks to the evaporator coil. Not only does this inhibit airflow, the moistened dirt can freeze on the evaporator coil. Frozen spots reduce the efficiency of the appliance, but they can also lead to a very expensive Residential Air Conditioning Repair in Covina CA because freezing can cause the coil to rupture. Ruptures in the evaporator coil cannot be fixed. Instead, the coil will need to be removed and replaced.
One of the best ways to reduce the need for HVAC repairs is maintenance. Servicing the AC at least once each year ensures the appliance is clean and functioning as expected. This often requires the skill of trained technicians like those employed at Cypress Heating & Air Conditioning because the appliance may need additional refrigerant. A low refrigerant level can damage the condenser system and may affect the efficiency of the appliance. There are other areas where cleaning is critical. For example, clearing the area around the condenser unit and rinsing off the external coil can help the system eliminate any accumulated heat as quickly as possible. Cleaning the inside of the air handler improves air quality and removing any dust from around the filtration system when replacing the filter reduces the amount of dust that can collect inside of the appliance.
