Airflow problems with your HVAC system can leave you dealing with discomforting issues like hot or cold spots, uneven temperatures in different rooms, and/or a drop in conditioned air output from the registers. What starts out as a gradual loss of comfort can escalate into a costly equipment breakdown or failure, so it’s vital to have the problem addressed. Here’s a look at some of the most common causes or airflow issues and what to do about them:
Obstructed Registers and Duct Openings
If you’ve closed some registers, or your return ducts are covered by furniture, drapes, throw rugs, toys or other items, it can cause temperature inconsistencies in different areas of your home and a damaging imbalance in system airflow. You can fix this by wiping down each vent cover and vacuuming out the duct openings, and then checking that your louvered registers are completely open and all supply and return vents are free from obstructions.
Clogged Air Filter
If you’ve neglected to change your system’s air filter and it’s become clogged by dust and debris, you’ll notice a drop in airflow at the registers. Restricted airflow can also increase your HVAC equipment’s workload and energy consumption, or even ruin a component. Checking the filter monthly and replacing it whenever it looks dirty is the best way to prevent such problems.
A ductwork system that’s poorly designed, damaged, or leaking can hinder proper airflow through your HVAC system. A trained HVAC technician should inspect your ductwork to determine the cause and the right remedy, which may involve repairing, sealing and insulating or replacing the ductwork.
If your existing HVAC system wasn’t sized properly, it may be too large to effectively heat or cool your home. HVAC components with too much capacity will short cycle, resulting in a decline in airflow from the registers every time they cycle off. To solve this, a knowledgeable HVAC professional will need to complete a detailed load calculation and install correctly-sized new equipment.
