Lately, you may have found that your home is no longer staying as cool as it once did even though the air conditioner is running constantly. After further investigation, you may have also found that the volume of air coming through your vents has decreased significantly. If so, below are a couple of possible causes and simple solutions for the reduced airflow coming from your central A/C unit.
1. Clogged up Air Filter
The first thing you should always check when trying to determine the cause of reduced airflow from your air conditioning unit is the filter. If the filter has become clogged up with dirt, dust, pollen, and pet hair, the air will be at least partially blocked.
Even if you have recently changed or cleaned your air filter, depending on whether you use disposable or reusable ones, check and change/clean the filter to see if it makes a difference. If so, try to remember to take care of the filter at least once a month. If you live in a dusty part of the country or have several pets, you may need to change it as often as twice a month.
If you have tried changing or cleaning your filter and find no increase in the airflow, there is another problem causing the issue.
2. Issues with the Blower Fan
The next thing you may want to check when trying to find the cause of reduced airflow is the blower fan. Since the fan is responsible for circulating air throughout the air conditioning unit and throughout your house, any problems with it will result in decreased airflow. Even if the fan blades are dirty, this can slow them down and impede their function.
To check the blower fan, turn off the air conditioner using the switch on the unit and unplug it or turn off the breaker. Then, remove the top of the unit so that you can better visualize the fan blades.
If the blades are dirty, use a mild detergent to clean them thoroughly. Then, replace the top and turn the air conditioner back on. If you still do not see a difference in the flow of air, there may be a problem that requires the help of a professional.
If changing the air filter and cleaning the blower fan does not increase your airflow, there may be an issue with the blower motor or condenser. If you suspect that this is the case, contact an air conditioning company that offers repair services like Aggressive Mechanical Contractors, Inc., and have them find and fix the underlying cause.Share
