Ductwork Repair in San Bernardino, CA — Book a Visit Today

One room that never gets cool while the hall register blasts is almost always a duct problem, not a thermostat problem. We do ductwork repair throughout San Bernardino, and in this area the usual finds are crushed flex runs in a 150-degree attic, disconnected boots, and tape that gave up years ago. Leaky ducts dump your cooled air where nobody lives while your system runs and runs. Confirm every supply vent in the house is open, then let us pull the attic hatch and trace it. Call us or send the quote form with the problem rooms listed.

Power here comes from Southern California Edison, gas from Southwest Gas.

Before you buy, look at SCE residential efficiency rebates and Southwest Gas efficiency rebates. We will not promise something that closed last quarter, but we will tell you what is running when we quote.

Replacements fall under California Title 24, Part 6 and normally need a permit, with HERS verification and CF2R/CF3R registration on most changeouts. City of San Bernardino Building and Safety Division handles them.

The federal 25C Energy Efficient Home Improvement Credit applies to qualifying equipment, and the efficiency tier it requires is worth checking before you choose a system.

Ductwork Repair in San Bernardino — quick answers

How do you find a leaky duct?

We start with a static pressure reading and room-by-room airflow, then inspect the accessible runs in the attic or crawlspace. Where needed we pressurize the duct system to measure total leakage and locate it, instead of guessing from the vents.

Is sealing enough, or do I need new ducts?

It depends on the condition of the material. Sound flex and metal with failed tape and loose joints seals up well. Runs that are brittle, crushed, rodent-chewed or holding wet insulation get replaced, because sealant on failing duct will not hold.

How long does ductwork repair take?

Targeted sealing and a few reconnections are usually a same-day visit. A full replacement in an average home commonly runs one to two days depending on attic access, layout and how many runs there are. We give you a timeline before we start.

Will fixing my ducts help my energy bills?

Leaking supply ducts push conditioned air into unconditioned space, so sealing them means more of what you paid to cool ends up in your rooms. We will not put a number on it, but the comfort difference in problem rooms is usually obvious.

How soon can you get to my San Bernardino home during a heat wave?

Call us and we will give you a real window rather than a guess. During July and August heat runs we book heavy, so morning calls usually land same day or next day, and we prioritise homes with no cooling at all, especially where there are elderly residents or small children. If you are waiting, close blinds on the sun side, keep vents open in every room and leave the fan setting on auto so the system is not fighting itself.

How it works

Step 1
Tell us the symptom
Call or fill in the quote form. We ask what changed, when it started, and what the thermostat reads. That tells us whether to bring parts for a cooling fault or a heating fault.
Step 2
We diagnose on site
A technician checks the thermostat, the electrical side, airflow through the filter and coil, refrigerant pressures, and the outdoor unit. You get told what failed and why, in plain words, before anything is replaced.
Step 3
Repair and verify
We make the repair, then run the system and measure the results at the vents. If a part needs ordering, we say so and give you a realistic window instead of a vague promise.

Why homeowners call us

Built for real valley heatWe work in areas where afternoons sit above 110 degrees and systems run for months without a break. That shapes how we size repairs, check capacitors and contactors, and judge whether a compressor is genuinely done.
Attic and package unitsPlenty of homes across the region run attic air handlers or rooftop package units instead of a garage furnace and a side-yard condenser. We are used to the access, the duct runs, and the drain issues those setups bring.
Dust and debris we expectAg dust, cottonwood fluff and grass clippings pack condenser coils and starve a system of airflow. We clean what we find and show you the difference, rather than adding refrigerant to a unit that just could not breathe.
Heating too, not only ACFurnace repair, heat pump faults and no-heat calls get the same attention as summer work. Ignition problems, cracked or failing components and short cycling all get diagnosed before we recommend anything larger.
