Don’t Choke the A/C

The first two photos are quite a common occurrence. Mulch packed up and around the unit and encroaching landscaping vegetation. There are times when the plantings are actually growing through the compressors. The mulch is especially a problem because the fine particles will be sucked into the unit and clog the cooling fins.

The lower two photos are examples of bad installations. In the third picture the compressors are too close to each other and the home. The bottom photo the unit is actually touching the foundation wall. Clearance around the unit should be a minimum of one to two feet and above three to four feet.

These problems will decrease the general efficiency of the compressor causing the unit to run longer and work harder. This will result in the home not cooling down sufficiently, especially on extremely hot days, and energy use going way up.

Having the outdoor compressor serviced by a qualified HVAC technician before every cooling season begins is  good, sensible general maintenance. Also not forgetting to service the indoor cooling coil and air handler are equally as important.
