Ductwork Repair — Book a Visit Today
We repair, seal and replace residential ductwork across Arizona, California and Nevada, and the usual culprits are attic runs that have pulled loose at the boot, crushed flex between joists, and old tape that gave up years ago. A visit starts with your complaint. If one room never keeps up, we measure temperatures at the registers, look at return sizing, then get into the attic or crawlspace with a light and a camera to find the leaks and the disconnects. Some homes need a few hours of sealing at plenums and boots. Others have brittle flex that is past saving, and we quote replacement of the affected runs. Call us and describe which rooms are the problem and we will bring the right materials.

The ductwork symptoms we hear most
- One bedroom is always hotter than the rest of the house Disconnected or crushed branch run, or a leaking boot dumping air into the attic
- The AC runs and runs but the house never gets there Supply leakage in unconditioned space, undersized return, or duct loss across long attic runs
- Dust settles on everything a day after cleaning Return-side leaks pulling attic and wall-cavity air into the system
- Registers barely move air even on high fan Kinked flex, collapsed liner, closed dampers or a restricted plenum takeoff
- A whistle or rumble starts every time the system kicks on Loose fittings, torn flex sleeve, or too much air trying to move through too little duct

Safe things to check first
Worth a look before you call — sometimes it saves you the visit.
- 1Change the air filter and note the date, since a loaded filter mimics a duct problem by starving airflow.
- 2Walk the house and confirm supply and return vents are open and not blocked by furniture, rugs or drapes.
- 3Check the thermostat is set to COOL or HEAT with the fan on AUTO, and swap the batteries if the screen is dim or blank.
- 4Look at the breaker panel for a tripped breaker on the air handler or outdoor unit, and clear leaves and debris away from the outdoor unit so it can breathe.

How do you find a leaky duct?
We start with your symptoms, then measure airflow and temperature at the registers to see which runs are underperforming. From there we inspect the attic or crawlspace directly, checking plenum joints, takeoffs and boots, and we can pressure test the duct system when the layout calls for it.
Is duct sealing enough, or do I need replacement?
It depends on the condition of the duct itself. If the flex is intact and the leaks are at joints, boots and the plenum, sealing solves it. If the inner liner is torn, the insulation is shredded or runs are crushed flat, we replace those sections instead of patching.
Can I just use duct tape on the joints I can see?
Duct tape fails in attic heat, usually within a season or two. Proper repair uses mastic or approved foil tape with mechanical fastening at the collar, and the leaks that cost you the most comfort are often at boots and plenums you cannot reach safely.
Will fixing my ducts help the rooms that never cool?
Often yes, because a hot room is frequently a run that came loose at the boot or got crushed during other work in the attic. We verify the cause before promising a result, since some rooms also need a larger return or a damper adjustment to balance properly.
How long does ductwork repair take?
Sealing a typical system takes a few hours once we have access. Replacing several runs is usually a one-day job, and a full duct replacement in a larger home can run two days. We tell you the scope after the inspection, before any work starts.
Do leaky ducts affect indoor air quality?
They can. Return-side leaks pull air from attics, garages and wall cavities, which brings dust, insulation fibers and odors into your rooms. Sealing the return side is often the single biggest IAQ improvement we make on an older home with attic ductwork.
How it works
- Step 1
Tell us the symptom
Call or fill in the quote form with what you notice. Warm air, no air, short cycling, a smell, a noise. Details like when it started help us bring the right parts on the first visit.
- Step 2
We diagnose on site
A technician checks the thermostat, the electrical side, refrigerant performance, airflow and the return sizing. We test rather than guess, then explain what failed and why in plain language before any work starts.
- Step 3
Repair and verify
We make the repair, then measure temperatures and airflow at the vents to confirm the system holds. If a duct or return is starving the equipment, we tell you what it would take to fix it.

Why homeowners call us
- We know stucco tract homesMuch of the housing we service was built fast with returns too small for the tonnage installed. That single duct in the hallway explains a lot of weak airflow complaints, and we look at it before we sell you equipment.
- Marine mornings, inland afternoonsCoastal condos fight humidity and salt air, while inland homes run long afternoon cycles in triple digits. Same system, different failure patterns. We set expectations for the climate your house actually sits in.
- Diagnosis you can followYou get told which part failed, what it does and what happens if it waits. No hurry, no scare talk. If the honest answer is that the system has a few seasons left, we say that.
- Repair before replacementMost calls end in a repair, not a new system. We quote replacement only when a repair will not hold or the cost stops making sense, and we explain the reasoning either way.
