Possible Causes of Low Air Flow in My Air Conditioner

Your air conditioner serves two basic functions in performing its duties: cooling the air, and then blowing that air through the ductwork that extends throughout your home. Many air conditioning repair calls focus on the first part of the equation, but the second is just as important. After all, what good is the ability to cool the air if you can’t pass it on to the space in your home? Here in La Habra, CA, our mild temperatures can mitigate some of that, but you still need to pay attention when the air flow from your air conditioner drops. It can cost you a great deal in wasted energy, as well as increasing the strain on your system overall. There are numerous possible causes of low air flow in your air conditioner, a few of which are listed below:

  • A bent or broken fan. When your fan blades get bent or broken off, or the fan itself is moved out of position, the air flow will drop. In most cases, the fan itself will need to be repaired.
  • A faulty fan motor. The fan motor may experience problems that prevent it from powering the fan adequately. They’re often electrical in nature—such as frayed wires or lose connections—but can also include over heating due to friction or objects jammed into the mechanism.
  • A loose fan belts. Fan belts in your air conditioner act just like fan belts in your car, and when they get loose or break, they can’t turn the fan blade the way you need them to.
  • Blockages. Blockages anywhere along the air passages will disrupt air flow. This includes build-up in the ducts, dents in the ducts and air filters which haven’t been cleaned in a long while.

Never attempt to correct a low air flow problem yourself. Instead, turn off the system and contact the pros at JC Mechanical Inc. immediately!
