Ductwork Repair, Sealing & Design
Finding and fixing the leaks and restrictions that keep good equipment from delivering comfortable air.
Duct systems in existing homes commonly leak a meaningful share of the air the equipment moves — often into attics and crawl spaces, where it does nothing for comfort. Sealing that leakage is usually the cheapest capacity you can buy.
Total external static pressure is the duct system's blood pressure. When it is high, the blower cannot move design airflow, and every symptom that follows — weak vents, iced coils, short furnace cycles — is downstream of that one number. Measuring it first keeps a duct problem from being misdiagnosed as an equipment problem.
Where a room simply cannot be satisfied, the fix may be a new run, a larger return or a dedicated ductless head rather than more balancing at the registers.
What the visit covers
- Static pressure testing to find restrictions
- Leakage inspection at plenums, boots and joints
- Sealing with mastic rather than cloth duct tape
- Insulating ducts in attics, crawl spaces and garages
- Repairs and redesign for rooms that never get enough air
Signs you need this
- One or two rooms are always hotter or colder
- Weak airflow at registers far from the equipment
- Rooms are dusty even with a clean filter
- Visible disconnected or crushed flex duct
- Whistling or roaring from the return when the fan runs

Questions
Ductwork & Sealing questions
Common questions about Ductwork & Sealing. Anything else, call (602) 203-2395.
Not covered here? Ask us directly — describing the symptom over the phone is usually faster than reading about it.
(602) 203-2395Once a year for a single-function system (cooling or heating), and twice a year for a heat pump or a system that does both, since it runs year-round. Manufacturers commonly require documented annual maintenance for warranty coverage — check the paperwork for your equipment.
A one-inch filter typically needs replacing every 1–3 months, sooner with pets or during heavy use. Thicker four- or five-inch media filters usually last 6–12 months. A filter that is dark across its whole surface is overdue, and a restricted filter costs you capacity and efficiency immediately.
Age, repair history and the cost of the specific repair drive the decision. A system past 12–15 years with a major component failure (compressor, heat exchanger) is usually worth replacing; a newer system with a failed capacitor or contactor is worth repairing. You should always be given both numbers and left to choose.
