3 Causes of Low Air Flow in Your AC Unit

When it comes to comfort from an air conditioning system, it isn’t only cooling power that’s necessary to keep you cool. The air conditioner must be able to blow out enough of that conditioned air through your vents to provide an even spread of lower temperatures through your home. If you notice that the flow of air from the vents has dropped, something is wrong and you should contact specialists to look into it.

When you need repairs for your air conditioning in Millcreek, UT, pick up the phone and call Design Comfort right away. You can trust our trained staff with all your home comfort concerns.

3 Reasons You Might Experience Low Airflow

  • Clogged filter: This is one of the more common troubles that can afflict an air conditioner, and fortunately it is one that you can easily prevent. The filter is designed to catch outside particles that enter the return vents and stop them from entering the AC’s cabinet. If the filter isn’t changed often enough, it will catch enough debris that it will start to cut off the flow into the AC, and that will cut down on the flow out of the AC as well. Along with lowering airflow a clogged air filter will force the system to work harder and could trigger icing across the coils. Change the filter once a month to prevent this from happening; should serious trouble start, call for repairs.
  • Blower fan malfunction: The blower fan in the air conditioner’s air handler send air from the return vents across the evaporator coil and then into the ventilation system. This is the work horse of airflow, so if the fan malfunctions because of a broken motor or mechanical problem, you’ll need to have trained repairs to restore it and your airflow.
  • Broken ductwork: The ducts that carry the air from the air handler to the rooms must maintain a tight seal along their length so they will not lose air pressure. It only takes a small hole of gap between sections to lead to a drop in the air pressure that will result in lowered airflow from the vents. Breaks need professional indoor air quality technicians to repair and seal them (no, duct tape isn’t the answer) not only to restore the AC’s airflow, but to protect the ducts from dust and debris contamination.

Call for the Right Repair Technicians

Because a drop in airflow can come from either problems in the air conditioning or the ductwork, make sure that when you call for repairs from technicians with skill in both HVAC work and indoor air quality services.
