Carrier air conditioner
Air conditioners alter the temperature of air helping you get more comfortable in your environment. Sometimes they break down and you feel lost and unable to fix them. Here is how to check for a few problems and fix them on your own before calling a professional.
AC units vary depending on where they are situated because they are made in different sizes to accommodate different buildings. 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. 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.
Ac repairs can consist of recharging and fixing and replacing parts. First the technician will carry out a diagnosis where he will inspect the parts, then he will check the pressure of the system using PSI, then he will do a performance check by checking the outlet temperature and from the pressure readings he will be able to determine what is wrong with the system. Sometimes it can be a leak and leak can be detected using a special dye that is added to the refrigerant and using a special back light the technician will add this mixture to the system and use the light to check for leaks. Leaks are fixed by fixing any holes within the system and filling it with the specified amount of refrigerant. Leaks when not detected early they can become corrosive and damage the compressor which would be costly to repair.
The technician will also get rid of any air in the system that could be affecting pressure readings and interfere with the performance of the system. The technician can also change the old refrigerant to the newer R-134a refrigerant which is environmentally friendly.
