Problems with airflow prevent your HVAC system from distributing warm or cool air, making your home less comfortable. Understanding what causes it can help minimize the strain on your furnace, heat pump, or air conditioning system. Doing so also helps prevent energy bills from skyrocketing. Here are some common causes of poor airflow and what you can do to fix them.
1. Blocked Condenser Unit
The condenser unit of a residential HVAC system is located outdoors, which means it is prone to blockages as a result of overgrown shrubs or grass near it. When this happens, the unit will have to work harder to disperse the heat, affecting airflow. Before it overheats, make sure the surrounding area is clear of any obstructions and perform the necessary lawn maintenance.
2. Obstructed Vents
The return and supply vents in every room in your home must be unobstructed to ensure consistent air distribution. Make sure the dampers aren’t closed and pieces of furniture aren’t blocking airflow. If your vents are open but not blowing enough air, the fan’s motor may be at fault. To be sure, get in touch with your local HVAC technician to have your system inspected.
3. Dirty Air Ducts
Failure to maintain your HVAC’s air ducts can lead to the accumulation of dust and debris inside them, affecting indoor air quality and airflow. Be sure that the local heating repair technician you work with for your scheduled HVAC maintenance performs a thorough duct inspection and cleans dirty ductwork.
4. Clogged Filter
HVAC filters remove dust and allergens from the air. However, they can get clogged over time, reducing airflow. Make it a habit to change filters once every three months, though you may have to do it more frequently if you have pets at home or family members who suffer from allergies. When finding a replacement air filter, consider checking its MERV rating, which measures how effectively the filter stops dust and other contaminants from entering your HVAC system.
