Air conditioners are available in several types and sizes but all have similar components and have to be often cleaned to obtain maximum performance and extend the life of the unit. Since units vary in size and style on site common sense and some mechanical ability are needed.
The most fundamental part of maintaining any air conditioner is cleaning the coils. All air conditioners will have two coils, one called the condenser coil and the other called the evaporator coil. In window type air conditioners the coils are extremely close with the evaporator coil being the one inside the conditioned space behind the filter.
The condenser coil is the one that is outdoors and declines the heat. The evaporator coil is typically pretty accessible with out removing much of the a/c outer cabinet. The condenser coil nevertheless is more difficult to get at the side that most of the dirt will develop on. You should attempt to eliminate the a/c devices’ external shell by removing any screws that are holding it. As soon as you have eliminated the outer cabinet you should have the ability to see the rear end of the condenser coil that may be so unclean it may not even look like a coil surface.
In many houses central air conditioning type air conditioners you condenser coil lies in the part of your air conditioner that sits outside. You might need to remove some louvered panels to get at the coil fins. The evaporator coil is located in an air handler of some sort in side the home. This might remain in the duct above your furnace or in an air handler in an attic. The evaporator coil can some times be a difficulty to obtain at. Constantly shut off power to the device and ware safety glasses along with gloves.
Now that you have access to both coils it’s time to clean them. Start by brushing off as much of the heavy dirt with a small compact stiff bristle brush so that the coil cleaner can be injected into the coil. Now damp the coils with a sprayer or garden tube being careful not to utilize excessive water pressure as to flex over or damage the fins. If you find that some fins are harmed you can fix them with a coil fin comb. Now spay on a categories quantity of coil cleaner injecting it into the coils so that it can start to loosen up the dirt. Coil cleaner in an aerosol is terrific for injecting the cleaner deep into the coil.
Sometimes a liquid concentrate or powder cleaner that can be mixed in a sprayer works well likewise since the wand of the sprayer fits into tight areas. These coil cleaners, brushes, coil finish treatment and condensate pan treatment can be purchased online at cooling and heating up keep & products. After letting the cleaner soak for 5-7 minutes it best to then rinse or flush the coil with water. If you utilize a no rinse type cleaner and strategy to run the a/c after you do not need to rinse the evaporator coil. I constantly advise flushing the condenser coil the help eliminate dirt. Repeat this process up until you see clean water coming out of the coil while flushing.
After you coils are clean you can apply a coil finish treatment that will keep dirt from sticking in the future in turn minimizing the frequency of coil cleaning. Descent on is a terrific product that turns you coils into self cleaning coils. Make certain to then clear the condensate drain that might be a drain tube coming from the evaporator or a weep hole in the window type a/c system pan. I also advise putting some type of condensate pan treatment tablets or pads in the evaporator pan to prevent future drain clog. Now reassemble your air conditioner and your all set.
