Ducts & airflow
A new system on leaky ducts is a new system that still cannot cool the back bedroom. We test leakage first, then replace, seal or resize.

Questions
Asked on most site walks.
Can you just seal what is there?
Sometimes. Under 20% leakage and the right sizes, sealing is enough. Crushed, undersized or 1970s ducts get replaced.
Why is the back bedroom always hot?
Almost always a long undersized run with no return path. We fix the run and add a jump duct or transfer grille.
Does this need a permit?
Yes, with a HERS test. We handle both.
