Air filter replacement. Heating and cooling systems rely on air filters to remove dust, pollen and other particulates from the air. This is so that dirt deposits do not form on the evaporator coil or get circulated throughout the house. Each air handler unit in your system will have its own air filter. Some HVAC system air filters are reusable, while others must be replaced when they get dirty. We can tell you which type of filter you have, confirm that the correct size is being used, and show you how to replace or clean the filter.

Coil cleaning. A central air conditioning system has an evaporator coil located inside each air handler, and a condenser coil located outdoors. Each coil contains a long, serpentine run of copper tubing, covered by aluminum fins that promote good heat exchange. Dirt that collects on coils and fins can reduce your system’s cooling capacity by 30%, forcing your A/C system to work longer and harder. Because A/C coils are tricky to clean (and prone to damage), it’s best to have coils professionally cleaned by us.

Condensate drain cleaning & clearing. In addition to cooling your interior air, your A/C system also removes excess humidity from the air. Water condenses out of the air and needs to drain outside; or to an interior drain. Part of regular A/C system service should include cleaning the condensate drain and making sure there are no clogs or obstructions that might cause backups.

Duct sealing and duct insulation. Has your ductwork system been checked for leaks or undergone leak-sealing improvements? If not, consider having this work done by DLC  Air Conditioning. Leaky ductwork can diminish the performance of forced-air heating or cooling by as much as 40%. If some of your ducts are located in unconditioned spaces like crawl spaces and attics, also consider having these ducts insulated to improve.
