Dirt is the biggest enemy of your furnace. It can waste fuel and drastically lower efficiency. Dirt affects all three basic components of your furnace, so cleaning is the most important part of regular maintenance. The three parts of the furnace that should be cleaned are the filter system, the blower, and the motor. A certified technician from Park Mechanical can handle the maintenance of your unit so you don’t have to deal with the hassle.
The furnace filter should be replaced or cleaned at the beginning of the heating season and about once a month during periods of continuous use. To check the filter, the technician would take it out and hold it up to the light. If it looks clogged, it’ll be replaced with a new filter of the same type and size regardless of the length of time it has been used.
The technician would then clean the blower assembly, belts and pulleys to the blower, and motor housing. Cleaning the blower is critical if your furnace has a squirrel-cage fan, because openings in this type of blower often become clogged with dirt. To clean the blower, the panel that covers filter will be removed to gain access to the blower or panel on front of the furnace. This panel may be using slip-fit on hooks or it may be held by a series of screws. Access to the inside of the blower is usually gained by sliding out the fan unit. If the power cord to fan assembly is not long enough to permit the fan unit to slide all the way out, then the cord will be disconnected. Wipe the motor housing clean to prevent any heat build up in the motor.
