An AC reduces indoor temperatures and distributes cool air via a ventilation system throughout your space. However, low airflow from the vents creates an uncomfortable environment with hot and cold spots. Since a weak airflow from your aircon points to an underlying malfunction, you must hire an AC repair contractor to evaluate your system and remedy the issue to improve airflow in your home. The following are a few possible causes of low airflow in your AC.
Dirty Air Filter
Air filters trap dust, debris, and other contaminants from the air as they can damage the AC's components. However, the trapped particles will accumulate over time, clogging the filters. As a result, airflow is restricted into the aircon, causing a weak airflow from the vents. Since the air filters clog after a while, contacting an AC repair expert is important to clean your air filters. If you have disposable filters, they will replace them for proper airflow in your home.
Blower Fan Issues
The blower fan powers airflow in your system by drawing air from the return vents and sending it into the system for cooling. Subsequently, it circulates the air to the ducts and blows it to your home through the vents. However, when the blower malfunctions due to a blown capacitor, frayed wiring, or a defective relay, it will lack the power to distribute air through the ducts—hence a weak airflow. This will not only cause the fan to run constantly, but it will also wear it down faster, consuming more energy and increasing your utility bills.
Ducts are passages running across the walls through which cool air from the air handler circulates to the vents. A leak in the ductwork will cause a pressure imbalance, resulting in low airflow from the vents. This is due to the ducts degrading over time, construction damage, or constant expansion and contraction due to frequent temperature fluctuation. Therefore, it is vital to engage an AC specialist to seal the ducts to prevent cool air from accessing unconditioned spaces.
Blocked Vents and Registers
Over time, dust particles from your home may accumulate on the vents, partially obstructing airflow from the AC. Moreover, you may accidentally block a register by placing furniture or other items, impeding airflow into the room. Thus, it is advisable to contact an AC repairer to vacuum the vents and registers to prevent compromising airflow in your home.
You do not have to withstand uneven cooling in your home. Instead, you should employ AC repair services such as Baton Rouge Air Conditioning & Heating to regularly service your unit for proper airflow throughout your space.
