Rooms that never match the thermostat, dust settling hours after you clean, and a system that runs and runs are classic duct problems. We do ductwork repair throughout San Diego, sealing crushed and disconnected runs, replacing collapsed flex in hot attics, and opening up returns that were undersized from the day the tract was built. You can confirm your vents are open and your filter is fresh before we arrive. From there we measure static pressure and airflow room by room.

Ductwork Repair in San Diego — quick answers

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 soon can you get to my San Diego home?

Call us and we will give you a real window rather than a guess. Same-day visits are often possible in San Diego proper, and we group calls by area, so a Clairemont or North Park address may fill sooner than an outlying one. Heat and no-cooling calls get moved up. If you smell gas, leave the house first, call 911 or SDG&E from outside, then call us.

How it works

  1. 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.

  2. 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.

  3. 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.
  • All major brands, gas & electricFrom Carrier and Trane to Lennox, Goodman, Rheem and Bryant, serviced independently.
  • Straight answersWhen a replacement beats a repair, we tell you, sometimes before we roll a truck.
