Why Does My HVAC System Have a Weak Airflow?

There are various causes for weak airflow in an HVAC system.  Some causes are easily corrected by homeowners, while other causes necessitate the skill of a trusted professional.  If you detect a weak airflow, there are a few things to consider before making a call for help.

First, it is important to check the air filter on the unit.  A dirty air filter can easily restrict airflow.  Also, check with the manufacturer to ensure that the unit has the appropriate air filter installed.  Sometimes, homeowners accidentally install the wrong filter, which can affect performance. 

Another possibility is that there is a problem with the power source.  Try checking the circuit breaker to determine if there is a problem with the power source.  Sometimes, simply shutting the power off at the circuit breaker and then turning it on again can fix the problem.  In these instances, sometimes the HVAC system is running on less than optimal amounts of power. 

Be sure to check the vents in the house.  Closed, or partially closed, vents can lead to weak airflow, and simply opening them can remedy the situation. 

Other problems, such as a faulty or dirty blower motor, can impact performance.  Sometimes, the blower wheel can accumulate dirt or dust, which results in weak airflow.  A worn fan belt and pulley malfunctions are some other fairly common causes for weak airflow in HVAC systems.  Additionally, dust can accumulate in the ducts your ducts over the years, so a build-up could be blocking airflow.

If you are experiencing less than optimal airflow in your HVAC system, consider checking the filter, vents, and power source.  If the airflow remains weak, contact the experts at A Quality HVAC Services to request an estimate from a skilled HVAC specialist.
