The first and most basic step to take to extend your air conditioners life is to change the filter. You should change it whenever it gets filthy. Depending upon the use, that could range from every 3 to six months. There are some filters out there which can last up to a year. Ask someone in the hardware store for more pointers.
Once a year, make certain that you check the evaporator coil found inside the air handler to make certain there is no dust build up. When the weather condition starts to cool, you should check the outside of the a/c unit. You should check around the unit and make certain there is no debris on the surface area of the condenser, as that will stop air movement. Also, you should check in between the fins of the condenser to see that its not clogged with dead bugs or pollen Go to this website . Spraying the condenser with a hose will typically be good enough to get rid of all the particles.
Although lots of air conditioners today utilize direct drive motors, it is a good idea to check the belt in the air handler. You might need to change it. If no change is needed, you might only need to oil the motor bearings once a year.
It is also good to check the contactors and various other electrical parts; many of them are found inside the condensing unit. The contactor operates the compressor, and the contacts get pitted and need to be changed occasionally. Various manufacturers utilize different types of contactors, so review the handbook to discover what kind you need.
