Everyone loves to feel the chilled air blow in a nice cool home after a day out in the heat. But if your central air conditioner has too weak airflow and air doesn’t appear to be blowing as it should, it can get quiet worse, affecting your indoor comfort level greatly.
So, if your central home air conditioner is not blowing enough to cool your indoor space, it is crucial to diagnose and correct the problem at the quickest.
Here is a list of things to check and see whether your central air conditioner needs any repair or replacement works.
Closed or partly closed registers problem
Technically, the chilled air at the evaporator is pushed by a fan through the ducts, which deliver the cool air in your indoor rooms through respective vents or registers. Homeowners can close these registers to avoid cooling when not needed in some part of their houses. But when some of these registers have been unintentionally closed or partially closed, the intensity of airflow will be affected greatly. So, reach out to the registers and make sure they are fully open. This will boost your system’s airflow speed.
If you are still facing weak airflow even when your registers are fully open, then your fan might not be powerful to push enough air through the ducts. This problem occurs when fan motors are not working optimally in producing enough force while blowing. A dirty fan blade may also reduce the intensity of the spins that oftentimes results weak airflow. So, it is important to access your fan motor to check whether it needs any repair or replacement. If you have set the blower fans to low speed, turn it up to the high speed to help increase the airflow.
There are a series of ductworks installed in your house’s basement, ceilings or walls, which serve as the passage of airflow from the blower to vents or registers. If not properly maintained, your duct may accumulate debris, or become leaked. This can greatly reduce the air pressure and minimize the airflow speed reaching to your living space. Having your ductwork checked for leaks or cleanliness can help maximize the air pressure.
If your filter is clogged with full of debris, dust, and lint, it can cause overheating as much of the air remain chocked off through the system, which considerably reduce the air flow pressure coming into your rooms. So, air filters should be timely cleaned or replaced to not only help maximize airflow pressure but also enhance the quality of air.
