Keep Your Home Comfortable With the Help of Your Local AC Repair

Some of the most expensive appliances in your home are the comfort appliances that keep it cool in the summer and warm in the winter. In many instances these are a combined unit referred to in the industry as an HVAC (Heating, Ventilation and Air Conditioning) and often called a central air or forced air unit by the homeowners. These units are typically split into two main cabinets where the inside unit is connected to the ducts and thermostat.

Central air works by using a compressed coolant which is circulated through the outside condensing system into the inner cabinet. The inner cabinet holds the furnace and an air exchange where the compressed coolant circulates through the evaporator coil. This coil picks up any local heat surrounding it and transfers it to the refrigerant where it is cycled back outside. Once the coolant is outside the house it runs through a larger coil so the heat can be transferred to the atmosphere.

While the process seems rather simple there are a number of mechanical parts on your HVAC that may require AC Repair. For example, the compressor or condensing unit can freeze up after extended use. Likewise, the blower fan inside the home can wear out or the motor could burn out. This blower actually services both heating and cooling functions so it sees service throughout the entire year. However, the most vulnerable components in any HVAC are the electronics. Your system could have controlling electronics in both the outdoor unit and the indoor one.

When the AC Repair technician has to fix these components they typically replace the boards to avoid further failure with electronics on the bad board. In many cases it is usually more cost effective to do this than to actually try and repair the board itself. Another source of electronic problems in some modern HVAC’s is the thermostat. Many older systems used a mechanical or switch operated system, but modern central air systems can make use of an electronic thermostat for better control and efficiency. Of course, with the help of air conditioning contractors like Rocky Top Air your older HVAC can easily make use of an electronic thermostat.
