A central air conditioning unit is a complex piece of machinery, but it helps to understand it if viewed as two larger operations working together. First is the refrigeration operation, the part of the AC that handles removing heat from one place (indoors) and then placing it elsewhere (outdoors). The second is the distribution operation, which takes the product of refrigeration (cooled air) and sends it out into the rooms of your house.
Fans are an important part of both operations: they draw air across coils to allow for heat absorption and release, and they send air through the ductwork toward the vents that open onto your living spaces. Without correct fan operation, an air conditioner faces trouble on two fronts. You can lose your cooling power, airflow, or both because of fan issues.
Malfunctions in fans need professional repairs, as do most issues in an air conditioner. For excellent air conditioning repair in Atlanta, GA from a company that always aims for 100% customer satisfaction, call Premier Indoor Comfort Systems.
AC Fan Troubles
A basic problem an AC fan can encounter is having its blades bent because of debris (gravel, stones, etc.) that enters the cabinet. A bent blade will begin to strike its casing, causing more damage—but at least it will create a loud clanging noise to alert you of the trouble.
Older air conditioners have fan belts connecting the blower motors to the fans. These belts will eventually suffer enough wear and tear (especially without regular maintenance) that they will fray and break. Not only will this stop the fan from working, but the belt will snap around the air handler and injure other components. Don’t try to change this belt yourself: it isn’t like fixing the engine belt in a car.
A fan can freeze and stop working because of heavy dirt and dust contamination. You will need a repair technician to open up the cabinet and dismantle the fan to clean it thoroughly. In some cases, the fan’s engine may also need replacement. (To avoid problems like this in the future, regularly change the air filter and schedule annual maintenance to clean the unit.)
Call Repair Technicians to Investigate Fan Problems
Not all fan failures stem from the fan itself: the system may have electrical problems or thermostat issues. When you detect trouble with an AC fan, call for experts to analyze the problem and find a proper solution.
