3 Causes of Low Air Flow

One of the major warning signs that an air conditioning system (or a forced-air heater) has developed a serious malfunction is when the airflow coming from the registers into the rooms drops. You will probably first notice this as uneven cooling in the rooms and an extended period required to reach the desired temperature. When you check on the vents and find that air is only sluggishly coming out, it’s time to call for experts in AC repair to investigate the problem.

There are a few different reasons that the airflow from your cooling system might drop, and it will take trained professionals to identify the specific cause and address it. Rely on the HVAC experts at Air On Demand when you need air conditioning repair in South Miami, FL. We have a staff of NATE-certified technicians to make sure you receive the best quality repairs for your cooling, done fast and right the first time.

3 Possible Reasons for Low Airflow

  • Clogged air filter: This is the most common cause of low airflow, and also one that is easily preventable. The air filter in your air conditioner catches particles inside the air that come through the return vent to prevent them from harming the interior of the cabinet. After a month of regular cooling, the filter will have a large amount of dust, lint, and other debris inside it, and this will close off airflow into and out of the system. Change the filter once a month throughout the summer (and any other time that the AC runs regularly) to keep this from happening, and call for repairs if it has caused a severe reduction in airflow.
  • Leaky ductwork: The problem may not originate inside the air conditioner itself, but from the ventilation system that distributes the air. Leaks from breaks and holes inside the ductwork will cause air pressure to drop inside the ventilation system, sometimes as much as 50%. This needs special ductwork repair technicians to handle: they will track down the leaks in the ventilation system and seal them.
  • Blower troubles: The blower in the air handler (the indoor unit of an air conditioner) sends air from the return vents past the evaporator coil and then into the ductwork. If the blower begins to fail due to problems with its motor or the electrical system, the airflow will start to plummet. This also means less efficient cooling because of the reduction of air across the coil. Blower problems need skilled technical work to fix.
