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.

Duct Questions, Answered Straight

How do I know whether ducts are leaking?
The signs stack up quietly: rooms starved of airflow, an attic or crawlspace that's oddly warm in winter, dust that returns days after cleaning, utility usage that keeps climbing without a usage story. But the honest answer is measurement — static pressure testing and a physical survey of the accessible runs find leaks that no symptom can localize. Most Wasatch Front homes with ducts in attics or crawlspaces have real leakage; the question is how much, where, and whether it's worth reaching. The inspection puts numbers on all three.
Can ductwork cause hot and cold rooms?
It's one of the most common causes. A room fed by a crushed or disconnected run will never keep up; a room whose return is starved will never shed heat; and a branch sized for a different floor plan underserves whatever got added later. But uneven rooms can equally be equipment, insulation, or control issues — which is why airflow testing and balancing comes before duct redesign on our list. Measure first: some rooms need ducts, some need balancing, and some just need the damper two rooms over set honestly.
Should ducts be repaired or replaced?
Repair wins when defects are localized and accessible — a disconnected run, a failed joint, crushed flex in one bay. Replacement enters when the system is fundamentally undersized for the home, contaminated by an event, unreachable for repair, or built for equipment the house no longer has. The decision is made with measurements, not age: static pressure, room delivery, and the condition survey. When it's genuinely close, we'll show both scopes — targeted repair against partial or full replacement — with their honest limits.
Will new equipment require duct changes?
Often, and the equipment survey catches it before install day. High-efficiency furnaces and variable-speed systems have specific airflow requirements; a heat-pump conversion changes the airflow picture entirely; and a new coil or cabinet can shift the connection geometry. The quote visit measures static pressure and reviews the duct system against the candidate equipment — so duct corrections appear as their own line items if they're needed, not as surprises while the install crew stands in your yard.
Do you clean ducts?
No — duct cleaning isn't among our services, and we'd rather say that than sell it. The honest context: cleaning addresses what's inside the ducts, while most dust complaints trace to return-side leaks pulling attic and crawlspace air into the system — which is a sealing job, not a cleaning one. When a home genuinely needs cleaning (post-renovation debris, an event), we'll tell you it makes sense and point you to a company that does it daily. Then sealing the leak that fed the mess is often the part that keeps it from coming back.
