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.

Inspect Vents and Registers

Begin by checking all accessible vents and registers for dust buildup, blockages, or visible mold. Make sure they are fully open.

Change Air Filters

Replace your HVAC system's air filters. A clogged filter can impede airflow and worsen air quality, making it essential to change them regularly.

Test Airflow

Turn on your HVAC system and feel for airflow at each vent. Uneven airflow may indicate blockage or duct issues that need addressing.

Check for Odors

Turn on your HVAC system and notice if any unpleasant smells emanate from the vents. If you detect a musty or strange odor, further inspection is needed.

Evaluate Energy Bills

Review your recent energy bills for significant increases. If your usage has risen without an increase in usage, this might indicate duct issues.

Pro Tip

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