Fan Problems with Your Air Conditioning

While your air conditioning system uses a couple of fans to assist with the cooling process, fans alone cannot cool a home. Instead, fans make you feel cooler because they make it easier for sweat to evaporate from your body. In this guide, we’ll look at how fans help cool your home and why you should call for air conditioning repair as soon as you encounter fan problems.

Air conditioners cool your home using a refrigerant cycle that absorbs heat from your home and releases it into the air. Refrigerant changes from a liquid to a gas at the indoor evaporator coil as it absorbs heat. Then, it changes from a gas to a liquid at the outdoor condenser coil as heat releases into the air.

Fans play an important role in this process. A condenser fan sucks in the outdoor air to help with the condensation process. It then helps the heat to disperse from the refrigerant and into the air. The indoor fan sucks in warm indoor air and cools it over the evaporator coil. The same fan then distributes cool air through the ducts. Here are some of the problems these fans may run into over time.

  • Debris in the Fan Motor: The fans are controlled by a motor that may be affected by debris. If your fan motor makes a grinding noise, there may be dirt in the motor or it may simply need lubrication.
  • Bent or Damaged Fan Blade: A bent or damaged fan blade may interfere with airflow, leading to a frozen evaporator coil and/or limited cooling. If this is the case, you may hear a rattling sound in your ducts or from the outside unit.
  • Overheated Motor: Like all mechanical parts, a motor may eventually fail. If a motor stops working, it most likely needs replacement. You should choose an experienced technician to replace a motor to ensure that it is the proper size for the system.

AC fan problems may reduce the efficiency of your air conditioner, limit the system’s cooling power, or cause you to feel no cool air at all. If you need Frederick MD AC repair, call Larry & Sons, Inc. today!
