Reduced Airflow: The Common Culprit Behind Inefficient Air Conditioning

Reduced airflow is a common issue that many homeowners encounter with their air conditioning units. It happens when the air passing through the filter is obstructed or restricted, making the AC unit less efficient in cooling down a room or a home. Here are some of the most common reasons for reduced airflow:

  • Dusty or clogged filters: Air conditioning filters tend to accumulate dirt, dust, and other debris over time. This buildup can clog the filter and restrict the flow of air. A clogged filter not only reduces airflow, but it can also put unnecessary strain on the AC unit, leading to higher energy bills and even system breakdowns.
  • Wrong size or type of filter: Using a filter that doesn't fit properly, or using the wrong type of filter, can also cause reduced airflow. A filter that's too small or too large won't be able to effectively capture airborne particles, while choosing a filter with the wrong MERV rating (minimum efficiency reporting value) can lead to decreased airflow.
  • Blocked air vents: Sometimes, reduced airflow can be caused by blocked air vents. Make sure that there's nothing (furniture, curtains, etc.) blocking the air vents and preventing air from circulating freely.

If you notice reduced airflow in your air conditioning unit, it's important to address it as soon as possible. Not only will this help keep your home comfortable during the hot summer months, but it can also prevent more serious problems from occurring down the line. Regularly cleaning or replacing your air conditioning filter, making sure the filter fits correctly, and clearing out any blocked air vents are all easy steps you can take to maintain optimal airflow and keep your AC unit running smoothly.
