Frequently Asked Questions
How do I know if my ducts are leaking?
Signs of duct leakage include rooms that won't heat or cool evenly, high energy bills, dusty rooms near duct runs, and the HVAC system running longer than expected. We can test your system to quantify leakage.
How much energy do leaky ducts waste?
Studies estimate that leaky ducts waste 20–30% of conditioned air in a typical home. Sealing them is one of the most cost-effective HVAC improvements.
Can I seal my own ducts?
You can apply HVAC mastic or metal-foil tape to accessible duct connections in unconditioned spaces. However, ducts inside walls and ceilings require professional attention.
Do you seal ducts in finished areas?
We access ducts through existing openings and in unfinished areas. For ducts inside finished walls, we work with what's accessible.
