A failing air conditioner can quickly become a huge energy waster. For instance, when the unit has not been well maintained and the refrigerant is low, it can cause the condenser to cycle more frequently than normal. Of course, this is a simple example of an AC failure. There are many other things that can go wrong with these comfort appliances because air conditioners are extremely complicated pieces of equipment. This is why AC Repair in Derby KS should always be handled by a professional.

The most common appliance for cooling the air in a home is the HVAC (heating, ventilation and air conditioning) system. This appliance typically comes in two major pieces, although larger systems may have more. The main portion is the condenser unit that is installed outside of the building. The purpose of the condenser is to compress a refrigerant so that it can collect heat. There are several ways that this unit can fail including a burned out condenser and faulty switches. Keep in mind that the condensing unit cycles on and off quite often and that modern refrigerants require extremely high pressures.

A common reason for AC repair in Derby, KS is freezing. This problem frequently occurs around the evaporator coil or the fittings that connect it to the condenser. Freezing can happen when the refrigerant level is low, but a more common cause is dirt. Dust and debris slip past any filter and a filter that is already dirty makes this issue worse. Plus, the AC creates condensation as a side effect of thermal transfer and this moisture collects around the coil. Dirt and moisture create a thick grime that cakes up on the evaporator coil. When the cold refrigerant passes through the coil, it can freeze this gunk solid.

A frozen coil can cause several problems. First, the ice can block the flow of air through the coil and hinder efficiency. Second, the metal of the coil can fracture and leak refrigerant. A ruptured coil cannot be repaired, it must be replaced. A technician can reduce the chance of freezing by removing the coil and cleaning it in an acid bath and charging the refrigerant level every year. Contact Kelley and Dawson Service for more details.
