When the heat of summer rolls around, the most important appliance in the home is the air conditioner. The AC works by compressing a chemical refrigerant and cycling it through a series of coils. The compression of the chemical causes a state change and allows it to collect heat. However, it places a lot of stress on the appliance because of the high pressures involved. The harder the system works, the more likely it is that something will break and require the need for HVAC AC repairs in Cobot AR.
The typical HVAC (heating, ventilation, and air conditioning) system comes as two units. The first is placed outdoors and houses the condenser. This is where the heavy work is handled and the main area where heat is released from the refrigerant. Along with the condenser is a fan to circulate air and a coil that allows the refrigerant to cool. There will also be a few electronics that controls things. Typical maintenance on this portion of the system should include cleaning the coil and testing the charge of the refrigerant. If the level is too low, then the system may operate inefficiently.
The interior unit houses the plenum or air exchanger, the evaporator coil, and the blower. This is the area where the treated air is gathered for distribution. When the HVAC is in cooling mode, the change in temperatures can create condensation, and this can lead to a clogged coil. One of the best HVAC AC repairs in Cobot AR is the cleaning of this coil because it improves the efficiency of cooling and the flow of air. Cleaning the evaporator coil can be difficult because some models will place the coil where it is difficult to access. In this case, it may be necessary for the AC technician to remove the coil and clean it in an acid bath. An HVAC is an expensive purchase that is designed to last for many years. One way to ensure that this happens is to keep it well maintained. Because this comfort system is two appliances in one, it is better to have it serviced at least twice each year. In fact, most manufacturers recommend that the AC portion is serviced in the early spring, and the furnace receives its service in the late fall.
