When you run your air conditioning, you expect to hear two sounds from it: the hum of the compressor (when the cooling cycle is on), and the whir of the fans. The blower fans are an essential part of both how an air conditioner cools down a home and how it distributes the conditioned air throughout the rooms.
Fans are the largest mechanical components inside an air conditioning unit. Like any mechanical device, they can suffer from operating issues leading to breakdowns. Losing any fan in an AC will cause a plunge in cooling ability and airflow, and you need to have the problems addressed as soon as possible. This requires work from an AC professional: never attempt fixes to complex mechanisms on your own without proper training.
Here are some ways to tell you have fan trouble in your AC. Whatever the issue, you can depend on South Air Inc. to assist you with your air conditioning in Atlanta, GA. Our team has more than a decade of experience with repairs on cooling systems of all brands and sizes.
Indicators of AC fan problems
- Drop in airflow from the vents: One of the earliest warnings you’ll receive that a fan has slowed or stop working is when the airflow from the vents feels weaker than it should. The air may still feel cold, but you will discover rooms will take longer to reach their target temperature, resulting in uneven cooling.
- Grinding and slapping noises: Bizarre, loud, and unpleasant sounds from an AC cabinet are almost always signs of repair needs. These sounds can mean a number of different problems for an air conditioning fan. On older ACs with fan belts, it could indicate a loose belt striking other components. Bent fan blades (which can occur because of debris in the cabinet) will cause the blades to hit the fan casing. Dying blower motors will create grinding sounds. Whatever the disruptive sound, you’ll need to call for repairs right away.
- Airflow/cooling stops entirely: These are signs of a fan that has completely stopped working. Listen to the cabinet to find out if the fan is moving. Often, a full fan breakdown is due to motor failure or a problem with an electric relay. Let a professional repair technician troubleshoot this for your and find out why the fan has stopper turning.
To help head off potential fan dilemmas, sign up for regular maintenance on your air conditioner. The majority of fan troubles stem from excess dirt and dust inside the cabinet, and regular maintenance from a professional will provide the cleaning and adjustments necessary to reduce this and keep your fans turning without excess strain.
