Ductwork Repair, Replacement and Airflow Testing
Ductwork determines whether conditioned air reaches each room at the airflow the equipment needs. CMB HVAC evaluates leakage, damage, insulation, sizing, static pressure, supply and return pathways, and room airflow before recommending work.

Ductwork Repair, Replacement and Airflow Testing
Ducts are the half of your HVAC system nobody sees and every comfort complaint travels through. The most efficient equipment in the world under-delivers through undersized returns, disconnected runs, and crushed flex — and the fix often costs a fraction of the equipment replacement homeowners assume they need first. We measure before recommending: static pressure, room-by-room delivery, and the duct system's actual condition.
A scope note we hold to: we repair, seal, insulate, design, and balance duct systems — duct cleaning is not among our services. If your concern is debris inside the ducts, we'll tell you honestly when cleaning makes sense and when it doesn't, and where to find it, rather than bill you for a service we don't perform.
Duct Work Backed by Numbers
Static pressure first
The duct system's breathing room measured before any recommendation — the number every duct decision hangs on.
Defects documented
Disconnected runs, crushed flex, failed insulation — photographed and written down before the quote.
Accessible vs. concealed, stated
What can be reached and sealed versus what's buried — named on the quote, never discovered mid-job.
Before/after verification
Airflow re-measured after the work — the improvement you paid for, in numbers.
