The compressor air filter is a vital part of any kind of air conditioning system. Because the evaporator coil itself works on convection, the cleaner the filter it gets, the more efficient the air conditioning system. Not all filters are made the same. Some of them can fail to function properly while others might actually harm the unit. If you have ever suffered with any kind of problems, then you know how important it is to ensure that you are doing everything possible to keep the unit running smoothly. Luckily, there are a few different ways to check your filter.
The easiest and most effective way to check a filter is to use a special technique that will work on almost any filter. The process involves inserting the nozzle of the vacuum cleaner that is attached to the coil and slowly pulling it back and forth against the filter. When the filter gets bumped, the motor will pull at the filter and cause it to eventually break down. This method will often show a different filter than what you are used to. If you are not sure which one you have, make sure that you purchase a new one. It might be an electrical filter or a chemical filter. A chemical filter is usually not used on a refrigeration unit.
Another method for checking a new air filter is by using a reverse osmosis system. This is a very powerful system that is designed to use pressure to force the salt out of water. The filter is located at the end of the large pipe that the saltwater is pumped through. Simply insert the water into the system, reverse the pump, and wait. You should hear water being pushed through the entire system. When it gets to the filter, push it back and forth against the filter. If you feel resistance, then it is time to replace the filter.
