Air Duct Cleaning Company in Kensington, CA
Most Kensington homes were built before 1960, which means most duct systems weren’t designed for modern forced-air HVAC. We’re Duct Cleaning Santee, and we’ve served Kensington since 2017. Our focus here is Air Duct Repair, because older ductwork leaks, separates, and pulls in dust from crawl spaces and attics before cleaning can even make sense. If your storybook or Spanish Colonial home still runs on original galvanized ductwork, call (833) 542-0752 and we’ll tell you honestly what’s worth fixing and what’s worth replacing.
Why Kensington Homes Are Different
Kensington sits on terraced hillside lots shaded by mature oaks and eucalyptus. That canopy is beautiful, but it loads the air with pollen and fine debris that settles into ductwork. The mild, fog-influenced climate means furnaces and air handlers don’t run hard most of the year, so whatever gets into the ducts tends to stay there. There’s no constant airflow to flush it out. Homes here were mostly built from the 1920s through the 1950s, first with gravity furnaces and later with early forced-air systems. Many were retrofitted over the decades, and those retrofits often left mismatched duct sizes and leaky connections at the transitions. When we open a return or supply plenum in Kensington, we expect to find a history of partial upgrades. That’s the job: clean what’s there, seal what’s leaking, repair or replace what can’t be saved. Crawl spaces are tight, attics are cramped, and hillside access means we carry equipment in carefully. None of that changes the work; it just changes how we plan the day.

Our Main Kensington Services
Kensington homeowners call us most often for two things: cleaning the decades of dust and pollen out of their ducts, and clearing dryer vents that have become packed with lint. Here’s what each job looks like in this city.
Air Duct Cleaning in Kensington
Most Kensington duct systems hold years of fine dust, oak pollen, and construction debris from past remodels. We connect professional-grade Rotobrush and Nikro agitation and vacuum equipment directly to the ductwork, creating negative pressure that pulls contaminants out without blowing them into the living space. In older homes, we inspect first. Ducts with separated joints or crushed returns need repair before cleaning, or the vacuum simply pulls in more attic and crawl space air. For the full picture of this service, see Air Duct Cleaning in Kensington.
Dryer Vent Cleaning in Kensington
Dryer vents in Kensington homes are often long, with multiple bends to reach an exterior wall from a hillside laundry room. That adds up to serious lint accumulation, which is a fire risk. We run rotating brushes and high-pressure air through the full length of the vent, then confirm airflow at the termination point. We treat every Kensington dryer vent as a safety issue, not an add-on. Full details are on Dryer Vent Cleaning in Kensington.
Air Duct Repair in Kensington
In Kensington, air duct repair is usually the first thing we discuss, not the last. Homes built in the 1920s through the 1950s with gravity furnaces were later converted to forced air, and those conversions rarely replaced the original ducts. The result is what we see constantly on Kensington hillsides: undersized returns, separated joints, rusted sections, and duct runs that were never intended to carry pressurized air. Cleaning alone won’t fix a system that’s leaking 20 or 30 percent of its airflow into an attic or crawl space. That’s why we offer Air Duct Repair as its own service, with the same equipment and attention we bring to cleaning.
Ductwork Repair
Signs you need it
You notice weak airflow in certain rooms, dust accumulating quickly after cleaning, or a musty smell when the system runs.
What it costs in Kensington
Ductwork repair in Kensington typically runs $290 – $620 depending on the number of joints and the accessibility of the crawl space or attic.
How we do it
We locate leaks with pressure testing or visual inspection, then seal joints with mastic and mesh, replace damaged sections, and re-support sagging runs before re-testing airflow.
Duct Replacement
Signs you need it
Your ducts are rusted through, crushed, or so undersized that sealing can’t restore proper airflow to the room.
What it costs in Kensington
Full duct replacement in Kensington generally ranges from $2,900 to $7,400 depending on system size, layout complexity, and whether the job includes new boots and plenum connections.
How we do it
We remove the old runs, size new ducts to the actual airflow needs of each room, seal every joint with mastic, and insulate where needed before reconnecting and testing the full system.
HVAC Duct Installation
Signs you need it
You’re adding a room, finishing a basement, or replacing a gravity furnace with a modern forced-air system that requires properly sized supply and return ductwork.
What it costs in Kensington
New HVAC duct installation in Kensington typically falls between $3,400 and $7,400 for a whole-home system, with smaller additions priced proportionally.
How we do it
We design supply and return layouts for balanced static pressure, install rigid or flexible duct properly supported and sealed, and then commission the full run by measuring airflow at each register.
What Air Duct Repair Costs in Kensington
| Item | Typical range in Kensington |
|---|---|
| Ductwork repair (sealing, joint repair, re-support) | $290 – $620 |
| Duct replacement (full system) | $2,900 – $7,400 |
| HVAC duct installation (new system) | $3,400 – $7,400 |
Can you repair ducts without replacing the whole system?
Usually, yes. Most Kensington homes have specific failure points: separated joints, crushed returns, or rusted sections. We repair those individually and leave solid runs in place. Replacement only makes sense when the duct is unsalvageable or badly undersized. Call for an honest assessment.
How long does duct repair take in Kensington?
Most repairs finish in one day, usually four to eight hours depending on crawl space access and how many joints need sealing. Full replacement of a large system may take two days. We’ll give you a clear schedule before work starts.

What Kensington Customers Say
"Quoted per system rather than the bait and switch per vent pricing everybody else in town uses. The number I was told on the phone was the number on the invoice."
- Stephanie Reed"Found a disconnected run in the crawlspace while they were in there and told me about it rather than cleaning around it."
- Paige Ackerman"Did the dryer vent while they were here for a small add on price. The dryer now finishes a load in one cycle instead of two."
- Daniel Thompson
