Every summer, homeowners call us because their air conditioner is running but not delivering enough cool air to keep the house comfortable. While there are several issues that can cause cooling problems, the most common reason we see requiring AC repair in Memphis, TN is surprisingly simple: restricted airflow caused by a clogged air filter. Fortunately, this is also one of the easiest problems to prevent.
Why a Dirty Air Filter Causes Cooling Problems
Your air filter plays an important role in protecting your HVAC system from dust, dirt, pet hair, and other airborne particles. As the filter captures these contaminants, it gradually becomes clogged.
When the filter gets too dirty, it restricts the airflow moving through your system. Your air conditioner must work harder to circulate cool air throughout the home, which can lead to reduced comfort, higher energy bills, and increased wear on system components.
In severe cases, restricted airflow can even contribute to frozen evaporator coils, causing the system to stop cooling properly altogether.
How to Check and Change Your Air Filter
Checking your air filter is a simple task that most homeowners can perform in just a few minutes.
First, turn off your HVAC system at the thermostat. Locate the air filter, which is typically found in a return air grille, an air handler, or near the furnace. Carefully slide the filter out and inspect it.
If the filter appears covered in dust, dirt, or pet hair, it is time for a replacement. Check the size printed on the side of the existing filter and install a new filter with matching dimensions. Be sure to follow the airflow direction arrows printed on the filter frame when inserting the replacement.
Once the new filter is installed, restore power to the system and resume normal operation.
Check Filters Monthly During Peak Summer Heat
Many homeowners assume air filters only need attention every few months. However, during the hottest part of summer, your air conditioner often runs for much longer periods each day.
We recommend checking your filter at least once a month during the peak cooling season. Some homes may need even more frequent inspections and replacements.
If you have heavily shedding pets, ongoing remodeling projects, construction dust, multiple occupants, or other factors that increase airborne debris, filters can become dirty much faster than expected.
