Heating and ac repair
AC repair is something complex and you may need to understand a number of things before you get started. There are many types of air conditioners, the car air conditioner, the wall air conditioner, the central air conditioner, the portable system and the split system air conditioner. Most air conditioners have the following similar parts, the compressor, the condenser, the evaporator, the expansion valve and the drier or accumulator. These parts are interconnected using pipes and valves. Refrigerant is the fluid which is also highly volatile that transports heat from one component to another. The air conditioner basically starts working when you turn on the AC and the refrigerant goes to the compressor where it is compressed and absorbs heat and changes from liquid to gas. Then it goes to the condenser where it is cooled sometimes in some systems the condenser may be fitted with an electric fan. After being cooled and changing back to liquid the refrigerant moves to the evaporator where it is cooled further and then air is blown across it for it to become cool and this cool air is then blown into your environment. The refrigerant then absorbs the heat from the air blown and it reverts to a gas. The drier removes any impurities on the refrigerant using filters and desiccant to absorb any moisture. The expansion valve controls how cool the air you receive will be. Then the process takes place over and over until the room is cooled. This is also referred to as the refrigerative cycle. Before acquiring a unit you should check how energy efficient it is and for some of the appliances industries they offer free installation of your unit.
At some point the air conditioner may start having problems and you should get it repaired by a certified technician from a quality service company near you. They will first do an initial diagnosis before establishing what the problem is and then make recommendations. If you do regular maintenance then they will only be small repairs to do. However, without maintenance you may find yourself having to replace components of the AC system which are quite costly. Most companies have the components there and will easily replace any parts that need to be repaired. They also offer to retrofit your old refrigerant with the newer environmentally safe refrigerant.
Always get a unit that is the perfect size, a small air conditioning unit will not effectively cool the house and a unit that is too large will run your bills too high as it turns on and off unnecessarily. It is always recommended to get a contractor to get you the best deal and for him to check your house for the most suitable type of unit. The contractor will check window dimensions, any previous duct work, the floor surfaces and the overall size of the house. Based on this information he will then select the most suitable fit with a high SEER rating for your house.
