If left unmaintained, coils will be unable to transfer heat effectively when covered with dirt & debris, causing all sorts of mounting problems such as your system overheating, compressor failing, and higher energy consumption.
For the coils to transfer heat effectively, the surfaces must be clean. The condenser coil is part of the outdoor unit and is always exposed to pollution, debris picked up by wind, and grass clippings from mowing, are all contributing factors that can hinder your condenser coil from performing at its optimal. If neglected, can slowly fill up with dirt, grime, trapping the heat inside; consequently, damaging the part. Even if your unit is located inside a mechanical room, they are constructed with louvers to provide outdoor air, still exposing your condenser coil to the elements.
For evaporator coils without proper cleaning, overtime it will be unable to effectively remove heat and humidity from the air in your space. While it may be a component situated indoors, it’s still exposed to dust in your building or home. If you don’t regularly replace your filters as recommended, it very easy for airborne particles to clog up the evaporator coil preventing it from cooling as effectively.
