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 Ductwork

Begin by visually inspecting your ducts for any obvious signs of damage or disconnection. Look for gaps, holes, or crushed sections that may impede airflow.

Check Air Filters

Examine your HVAC system's air filters and replace them if they are dirty. Clogged filters can significantly reduce airflow and system efficiency.

Seal Duct Leaks

Use mastic sealant or foil tape to seal any visible leaks around joints and seams in the ductwork, ensuring a tighter fit and improved airflow.

Clear Blockages

Ensure that all vents are unobstructed. Remove any furniture or items blocking airflow to promote better distribution of heated or cooled air.

Assess Insulation

Check the insulation around your ducts. If it appears old or damaged, consider replacing it to prevent condensation and improve energy efficiency.

Monitor System Performance

After making adjustments, monitor the performance of your system for a few days to identify any further issues or improvements in airflow and temperature consistency.

Pro Tip

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