What Causes Weak Airflow in Your HVAC System?
A lack of airflow through your HVAC system can be maddening, especially during the hottest summer days. The last thing you want is a malfunctioning cooling system that doesn’t provide the relief you were expecting.
This blog will dive into why your HVAC system may be experiencing weak airflow and how to fix it.
Dirty Air Filters
One of the most common culprits behind weak airflow is dirty air filters. Over time, dirt and debris can build up on your air filter, causing blockage and reducing airflow. To avoid this issue, check your air filters regularly and replace them when needed.
Duct Leaks
Another potential cause of weak airflow is duct leaks or cracks in your HVAC system’s ductwork. Duct leaks can cause the conditioned air to escape before it reaches its destination, resulting in weak airflow and higher energy bills due to wasted energy.
Check for any visible signs of damage or wear and tear in your ductwork, such as tears or holes, and repair them promptly if necessary.
Closed Dampers
Another issue causing weak airflow is closed dampers associated with zoning systems in multi-level homes or buildings with multiple rooms with different temperature requirements throughout the day.
Check that all dampers are open when increasing airflow throughout your home or building for maximum indoor efficiency and comfort.
Outdoor Unit Issues
Suppose there’s an issue with the outdoor unit itself. In that case, this could also result in weak airflow inside the home or building due to a lack of power being supplied to the fan motor located inside the unit itself—which pulls air through the evaporator coil—or an obstruction blocking air from getting into the unit at all (such as debris).
If you suspect an issue with the outdoor unit, contact a professional HVAC technician immediately for assistance resolving it quickly and safely.
Blocked Vents
Another common problem that can lead to weak airflow inside a home or building is blocked vents due to furniture placement or items covering them up entirely–for example, curtains covering vents near windows or couches blocking heat registers near walls or floor vents throughout living areas of a house.
To prevent blocked vents, ensure that all vents are unobstructed for optimal air flow throughout every room in your home or building for maximum comfort levels indoors all year long.
Refrigerant Leaks
Leakage from refrigerant lines within an HVAC system can lead to the following:
Reduce its ability to cool properly.
Weaker-than-expected airflow throughout indoor spaces.
Higher energy bills due to the inefficient operation caused by less refrigerant within its lines.
If you suspect something like this may be happening, contact a professional so they can inspect everything thoroughly before making any necessary repairs.
