How Can I Seal a Leaking Air Duct to Improve HVAC Efficiency?

You can seal leaking ducts by scheduling professional Aeroseal duct sealing with ABC Plumbing, Air & Heat. We list Aeroseal and duct cleaning among our Tampa Bay HVAC services, and our NATE-certified technicians diagnose duct-related airflow issues like uneven cooling. For a quick check, you can look for obvious gaps at visible duct joints, but hidden leaks usually need pro sealing.

Quick checks:

  • Look for separated or loose duct joints you can see.
  • Replace a dirty air filter to help airflow.
  • For hidden leaks, book Aeroseal duct sealing.
