Cottonwood season and spring in general can be brutal on your outdoor air conditioning unit! This before and after picture from one of Air Mechanical’s yearly maintenance calls displays how important an annual equipment service call really is! In our northwestern suburb region of Anoka and Washington counties (Ham Lake, Blaine, Andover, Anoka, Forest Lake) cottonwood trees are “blooming” this time of year. Their particular brand of cotton fluff accumulates everywhere including onto your condenser.
An air conditioner needs to breath meaning a proper flow of air is necessary to keep your system working efficiently. If the area where warm, indoor air is clogged; like this before picture; the fan motor on your furnace will be working very hard to push out that warm air through all of this gunk. Eventually, the motor will wear out prematurely.
Similarly, your furnace filter should also be relatively clean and free of debris for the same reason. A build up of debris causes the furnace to work harder to move the air inside your home. This raising of static pressure is damaging to your equipment and causes a real dollar loss in utility dollars.
Two simple things to ensure optimal efficiency and life span of your heating and cooling equipment:
- Have your equipment professionally cleaned and maintained annually (furnace in the fall, air conditioner in the spring).
- Change your furnace filter regularly. (Generally monthly for a 1″ filter, quarterly for a 4″ filter.)
