Air Duct Cleaning Company in Kensington - One Flat Price, Before-and-After Photos

Air Duct Cleaning Company in Kensington, CA

If your Kensington home has rooms that never quite heat or cool the way they should, the problem is often in the ductwork itself, and that’s where air duct repair comes in. Kensington isn’t a tract-home town. It’s a hillside enclave of architect-designed houses built between the 1920s and 1960s, many expanded over the years, almost all running on older segmented sheet-metal duct systems. When those systems leak, sag or separate, we clean it, and if it’s broken, we fix it. Call (844) 459-0252 for a free estimate. We answer 24/7.

Why Kensington Homes Are Different

Kensington’s ductwork was engineered for a different HVAC era. The forced-air and gravity furnace systems in these 1920s to 1960s hillside homes were sized and laid out for the equipment of that time, not for the modern furnaces and heat pumps that have replaced them. Add decades of renovations and additions, and you get segmented runs that don’t line up cleanly anymore. Original trunks branch in ways a current system never would.

Then there’s the terrain. These lots are sloped, so duct runs snake through crawlspaces and attics on grades that collect hillside dust over time. And the East Bay hills have a smoke season. Late-summer and fall wildfire smoke is a recurring reality here, and fine ash works its way into returns and settles in the ductwork. Homeowners often chalk it up to “the house just being dusty.” Usually it’s a clogged return and a leaking joint. In a heavily owner-occupied town where people stay in their homes and remodel rather than move, the duct system carries the accumulated history of every change made to the house. Cleaning and sealing it is retrofit work, not routine maintenance.

Our Main Kensington Services

Two jobs come up again and again in Kensington homes: cleaning out decades of hillside dust and smoke ash, and clearing the dryer vent before it becomes a fire risk.

Air Duct Cleaning in Kensington

In Kensington, cleaning ductwork means dealing with segmented sheet-metal runs that have pulled in hillside dust and, in smoke seasons, fine ash. We agitate the ducts mechanically with Rotobrush rotary brush systems, then capture what’s loosened with Nikro HEPA-rated vacuum equipment, held under negative pressure with Abatement Technologies machines so contaminants don’t drift back into your living space. Filter-clogged returns that look like “the house is just dusty” often turn out to be the real culprit. For a fuller picture of how we approach the work, see air duct cleaning.

Dryer Vent Cleaning in Kensington

Your dryer vent is a fire hazard waiting to be cleared, and in older Kensington homes the vent run is often longer and more convoluted than the builder intended, especially after an addition or a relocated laundry room. Lint packs into those bends and cuts airflow, which makes the dryer work harder and run hotter. We clear the full run, not just the first few feet, and confirm airflow at the exterior termination. Property managers with multiple units on a hillside lot should treat this as scheduled safety work rather than a someday chore. Details are on our dryer vent cleaning page.

Air Duct Repair in Kensington

Air duct repair in Kensington is really retrofit work. Original 1920s to 1960s sheet-metal systems were built for a much older HVAC era, and decades of additions and equipment swaps have left joints that no longer seal, trunks that sag, and runs through crawlspaces and attics that have quietly separated. Smoke season makes every gap matter more: a leaking return pulls hillside dust and fine ash straight into the system. We clean it, and if it’s broken, we fix it. That’s the core of our air duct repair work, and it’s the reason we can diagnose a structural problem rather than just vacuum around it.

Ductwork Repair

Signs you need it

You notice a room that never warms or cools like the rest of the house, whistling or rattling at the registers, visible dust streaks around a joint, or higher energy use without a change in how you run the system.

What it costs in Kensington

Minor ductwork repair in Kensington typically runs $150 to $450, while larger repairs on segmented sheet-metal runs often land between $400 and $900, with the written estimate setting the final price.

How we do it

We inspect the accessible runs under negative pressure, identify the failed joints, crushed sections or disconnected segments, then seal, reconnect or rebuild the affected sections and verify airflow at the registers afterward.

Air Duct Replacement

Signs you need it

The ductwork is so deteriorated that patching it would only buy a season, with collapsing flex, rusted-through sheet metal, or a layout that simply doesn’t match the current furnace or heat pump.

What it costs in Kensington

Replacing a duct run typically costs $450 to $1,200, and a full system replacement ranges from $2,500 to $6,500 in Kensington, with the written estimate setting the final price.

How we do it

We map the existing layout, remove the failed sections, install new ducting sized for the current equipment, seal the joints and returns, and confirm pressure and airflow before we leave.

What Air Duct Repair Costs in Kensington

Can you fix a duct problem in an older Kensington hillside home without replacing everything?

Usually yes. Most 1920s to 1960s Kensington duct systems can be repaired section by section, sealing and reconnecting the failed runs while leaving sound sheet metal in place. We only recommend replacement when the ducts are too deteriorated to hold a repair.

Why does my Kensington house feel dusty even after cleaning?

Because the dust is coming in through the ducts, not settling from the rooms. On a sloped Kensington lot, returns often pull dust and smoke-season ash through a leaking joint or a filter-clogged return. Repairing the leak is what stops it.

Brands We Service in Kensington

We work with indoor air quality equipment including Honeywell and Aprilaire systems, and we bring Abatement Technologies containment gear to every job. If your Kensington home has a whole-home air quality setup, we can service it alongside the ductwork. We don’t claim to stock parts locally, so turnaround depends on the part; see our brands for the full list.
