Central air conditioning can be a hassle to fix when something breaks or a certain component malfunctions. But there are also some very easy preventive maintenance stuff that you can do to evade many common problems that happen in central air conditioners.
One thing that you should know are the main parts that make up residential central air conditioning system. The air handler, which is usually located inside a closet in the house, and the condensing unit which is always located somewhere outside of the house.
The first thing you can do is to make sure that you have a clean air filter at all times. You should check it and replace it once a month, depending on what type of air filter you have. If you have a dirty air filter the air will be restricted and cause your HVAC system to operate less efficient.
Clean out your condensate line in your HVAC system every couple of months. This can be done by purchasing slime tablets, blowing out the line with CO2 or nitrogen, or by using a wet dry vacuum. When a condensate line gets clogged up it could shut down your unit, or flood your house.
If you find that your line backed up and shut down your air conditioning system, or flooded the house you will have to clean the line out. It will probably require a wet dry vacuum to do this, since the slime tablets are mainly made for preventing slime and sludge inside the condensate line.
Make sure that both of the coils on the air handler and the condensing unit are kept clean. For the air handler coils all you have to do is make sure that you always have a clean filter in, then you should be fine. The inside coils in most cases get dirty because of not having an air filter installed at all.
The outside coils usually do not get dirty as often as the ones that are located inside. The problem that happens most is bushes, leaves, plants, that are close to the condensing unit and block the hot air that is trying to be blown out. So make sure your condensing unit has a couple of feet of free space all the way around it.
When your HVAC system is cooling properly, there should be cool air coming out of the vents inside and hot air from the condenser outside. If this is not happening then you could possibly have a Freon leak, which can only be fixed by a licensed HVAC technician.
Those are just a few simple steps that the average Joe can do to keep their central air conditioning running good. There are many things that can go wrong on HVAC systems, so do not neglect preventive maintenance and increase the odds of something breaking.
