What to Do Next

Step-by-Step Action Plan

Follow these steps before calling a technician — you may be able to resolve the issue yourself.

1

Visual Inspection

Begin with a thorough visual inspection of your ductwork. Look for visible signs of damage, such as holes or disconnected segments. Check all vents to ensure they are open and unobstructed.

2

Airflow Test

Perform an airflow test by placing your hand near the vents. Compare airflow from different rooms to identify any significant discrepancies that could indicate a duct problem.

3

Check for Leaks

Use duct tape or mastic sealant to seal any visible leaks found during your inspection. This will help reduce energy loss and improve efficiency.

4

Inspect Insulation

Examine the insulation around the ducts, especially in unconditioned spaces like attics or crawl spaces. Ensure it is intact and adequately installed to prevent energy loss.

5

Change Filters

Regularly changing your HVAC filters can significantly improve airflow and prevent blockages. Check and replace filters every 1-3 months, depending on usage.

Pro Tip
Always turn off power to the unit at the breaker before inspecting any components. Safety first — even for simple checks.
