Air Conditioners – Some Things to Know
It often happens that the air conditioner in the house is neglected until the day you notice no cool air coming from it. This is usually during the hot days of summer, when your AC unit is most needed. You try to crank down the settings to force some cool air, but nothing. Your air conditioner is broken and you need a qualified HVAC contractor to fix it (or replace the broken AC unit with a new, efficient model).
This need not happen if you know some basic facts about air conditioners and how to properly maintain them. Let air conditioning repairs be done on the most complex of things, for example, if the system needs refrigerant because of low levels due to a leak. The detection of the leak and the handling of the refrigerant are best left to professionals.
What you have inside your room is called the evaporator of the air conditioning unit. This is where the cool air comes from. In front of the evaporator, there is an air filter. As the name implies, it filters dust and other particles from the air before the air enters the unit. The most basic maintenance you can do is to clean this filter regularly. The occurrence of this task depends on how often the unit is used. To be safe, cleaning the filters should be done on a monthly basis. Running water will do. Typically, air conditioner manuals have instructions on how to properly maintain the filter. It is best to consult the manual if ever there are special instructions on how to do so.
Your professional also recommends having no obstructions in the path where the air is coming out of the unit. In fact, this is also true for air coming into the unit. There should be a complete, unimpeded air flow to the air conditioner. Any blockage to this flow will result in a decreased performance leading to air not being cooled and even icing of the evaporator.
On the outside, this is where you are likely to find the other two main components of an air conditioner. These are the compressor and the condenser. The former is the heart of the system which pumps refrigerant throughout the unit. It is this flow that gives the air conditioner its cooling ability. If this flow is restricted, cooling is affected. The latter is where the heat taken by air from your room is taken out into the surroundings. If you have tried to put your hand into the air coming out of the condenser, you will notice that it is hot. It should be. If not, then there are problems to the unit. Problems to these two units usually require Las Vegas air conditioning repairs.
There is not much maintenance you can do to these two units outside except to ensure that there are no restrictions to the air flow of the condenser and that its coils are clean. If you want to be sure, give us a call.
