If you think there are hot and cold spots throughout your space, or your air conditioning unit blows warm air, this may be due to poor AC airflow. This can make your home feel hot and humid and cause your energy bills to rise. Should you ignore the problem for too long, the strain on your system can also lead to compressor failure.

Read on as Cool Zone Air Conditioning & Heating, a leading provider of top-quality AC replacement services, shares four reasons behind poor AC airflow.

  • Clogged Air Filters – The air filters ensure good indoor air quality by removing small particles like dust and pet dander and keeping them out of your equipment and ducts. Over time, however, your air filters can get overloaded and clogged. This can impede your HVAC airflow and lead to hot and cold spots and stuffy air. Make sure to replace your AC filters every two to three months, depending on where you live and how many people and pets live in your home.
  • Blocked or Leaky Ducts -If your AC filters are clogged, dust can accumulate in the ductwork. Keep in mind that ducts that are too narrow or small can become easily clogged. In older buildings, rodents, birds, or insects can also build nests in HVAC ducts. As time passes, the walls of the ductwork can develop holes or cracks where air leaks out, reducing airflow further. Get in touch with an AC maintenance technician to have your ducts inspected, cleaned, and sealed.
  • Dirty Condenser Coils – Your air conditioner’s condenser unit and its coils release the heat that is removed from your indoor space. However, since it’s part of the outdoor unit, the coil can get so dirty that it cannot release heat effectively. This can cause the unit to work harder to cool your indoor space, resulting in AC airflow issues. If your condenser coils look dirty, turn them off inside, sweep up around the area, and wash off the remaining dirt with water from a garden hose.
  • Wrong AC Unit Size

When it comes to HVAC sizing, bigger is not always better. If the AC is too big, it runs inefficiently and cycles on and off too frequently. They never run long enough to eliminate humidity from the space, making your indoors feel uncomfortable and stuffy. Meanwhile, if the AC is too small, it has to work harder and longer. This can shorten the lifespan of your unit and lead to increased utility bills.
