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

Air Duct Cleaning Company in Berkeley, CA

Air duct repair in Berkeley usually means addressing decades of deferred maintenance, not just sealing a loose joint. Homes here, particularly the 1900s through 1940s bungalows and brown-shingle Craftsman houses, still run on original sheet-metal ducting that was never designed for modern filtration or a sealed building envelope. At Hallmark Air Duct Cleaning, we match Rotobrush and Nikro extraction systems to the specific condition of your ductwork, and we repair the structural problems we find rather than vacuuming around them.

Why Berkeley Homes Are Different

Berkeley’s housing stock predates forced-air heating as we know it. Most of the flatlands and hills were built between 1900 and 1940, and many homes started with gravity furnaces that were later retrofitted with blowers and early flex duct. The result is uninsulated, undersized ducting with gaps at every joint. In the Berkeley Hills, ZIP codes 94707 and 94708, duct runs often pass through unconditioned crawlspaces and attics where damp marine air from the fog belt collects. That moisture, combined with rodent activity, creates contamination most flatland crews rarely see. Down in 94705 and 94709, dense lot-line additions mean retrofitted ducting snakes through tight spaces with disconnected joints and collapsed sections. Cleaning here is really a restoration job on century-old systems.

Berkeley’s mild climate also means HVAC systems sit idle for long stretches. Dust, pollen, and debris settle and accumulate undisturbed. When the heat or AC does kick on, all of that moves through the living space at once. And in pre-1950 homes, we frequently encounter asbestos-wrapped ducts or transite flue connections that require specific handling protocols before any cleaning begins. Our home service approach accounts for all of this from the first inspection.

Our Main Berkeley Services

Berkeley homeowners call us most about two things: cleaning the ductwork that has gone decades without attention, and clearing dryer vents that pose a genuine fire risk. Both jobs get the same equipment-serious approach.

Air Duct Cleaning in Berkeley

We clean the full duct system in homes across Berkeley, from flatland bungalows in 94705 to hillside properties in 94707 and 94708 where original ducts run through damp crawlspaces. Our process uses Rotobrush rotary-brush extraction for sheet-metal ducting and Nikro industrial equipment for larger or heavily contaminated systems. Abatement Technologies negative-air and HEPA-filtration equipment contains what we dislodge, so contaminants are captured rather than redistributed through your living space. For the full scope of what this involves in Berkeley’s older homes, see Air Duct Cleaning in Berkeley.

Dryer Vent Cleaning in Berkeley

A dryer vent in a Berkeley home is typically a long, narrow run through a crawlspace or out a roof, and it collects lint steadily. In hillside neighborhoods, vents often exit through roofs with screen caps that trap debris. We treat dryer vent cleaning as a fire-safety service, not a filler add-on. The work includes clearing the full vent run, checking the termination point, and confirming airflow. Berkeley’s older laundry rooms frequently have vent runs that were retrofitted poorly, with sags and kinks that hold moisture. See Dryer Vent Cleaning in Berkeley for specifics on how we handle these conditions.

Air Duct Repair in Berkeley

Air duct repair in Berkeley addresses what cleaning alone cannot: the structural failures that cause air loss, contamination entry, and wasted energy. In a 1920s Craftsman near the Elmwood or a 1930s bungalow in central Berkeley, disconnected joints and rusted-through sheet metal are common. Hillside homes in 94707 and 94708 add another layer: duct runs through unconditioned crawlspaces that are active habitat for roof rats and deer mice. We routinely find nests and droppings inside ducts that look fine from the register. Repairing the duct system is the root-cause fix. For a deeper look at the full repair scope, see Air Duct Repair.

HVAC Duct Installation

Signs you need it

Your Berkeley home still runs on gravity-furnace ducting or a patchwork of early flex runs that cannot move air efficiently, and rooms at the end of runs stay cold or hot.

What it costs in Berkeley

HVAC duct installation in Berkeley typically ranges from $2,500 to $6,800 depending on the number of runs, access difficulty in crawlspaces and attics, and whether asbestos abatement is required.

How we do it

We remove old duct sections, size new runs to the system’s actual CFM, install sealed and insulated ducting, and balance airflow at each register.

Air Duct Replacement

Signs you need it

Duct sections in your Berkeley crawlspace are crushed, rusted through, or so contaminated by rodent activity that cleaning cannot restore them to safe condition.

What it costs in Berkeley

Air duct replacement in Berkeley generally runs $1,800 to $5,200, with hillside crawlspace access and asbestos-wrapped duct disposal pushing costs toward the higher end.

How we do it

We remove and legally dispose of old duct material, install new sealed ducts sized for the system, and verify airflow with a post-installation static pressure check.

Ductwork Repair

Signs you need it

You feel weak airflow from specific registers, hear whistling at joints, or see dust streaks around vent covers in your Berkeley home.

What it costs in Berkeley

Ductwork repair in Berkeley typically falls between $350 and $1,400 per section, with prices varying by access difficulty and the number of joints that need sealing.

How we do it

We locate leaks with a pressure test, seal joints with mastic or foil tape, reconnect separated sections, and add support hangers where ducting has sagged.

Duct Replacement

Signs you need it

Flex duct in your Berkeley addition or retrofit has collapsed, is torn, or has been chewed through by rodents in the crawlspace.

What it costs in Berkeley

Duct replacement in Berkeley runs $1,500 to $4,800 on average, with crawlspace and attic access in hillside homes requiring additional labor time.

How we do it

We pull damaged flex runs, install new R-6 or R-8 insulated flex sized correctly, seal connections with mastic, and strap the run to prevent future sagging.

Ductwork Installation

Signs you need it

You are adding a room or ADU in Berkeley and need new duct runs connected to the existing system, or your current ductwork is too undersized for the blower.

What it costs in Berkeley

Ductwork installation in Berkeley generally starts at $2,500 and runs to $6,800, with multi-story homes and dense lot-line additions adding complexity.

How we do it

We design the shortest effective run layout, install sealed and insulated ducting appropriate for Berkeley’s damp climate, and balance the system at completion.

What Air Duct Repair Costs in Berkeley

Duct repair pricing in Berkeley moves with access difficulty, system size, and whether pre-1950 asbestos handling rules apply. We give one flat price per system before any work starts, so you know the full cost going in.

What is the most common duct problem in Berkeley homes?

Disconnected joints and rodent damage in crawlspace duct runs. In hillside ZIP codes 94707 and 94708, roof rats and deer mice nest in unlined crawlspaces, and ducts there are frequently chewed through or filled with droppings. Flatland homes more often have rusted sheet metal and collapsed flex from retrofit additions.

Do I need asbestos testing before duct repair in Berkeley?

In many pre-1950 Berkeley homes, yes. Original ducts may be wrapped in asbestos insulation or connected to transite flues. Alameda County rules require specific handling before any repair work can touch those materials. We identify suspect materials during inspection and coordinate proper testing and abatement before proceeding.

Brands We Service in Berkeley

We work across Berkeley with duct systems and air quality equipment from Honeywell and Aprilaire, plus Guardsman components. Parts for common configurations are stocked locally in our Oakland shop, which means most repair jobs in Berkeley can start without waiting on a distributor shipment. See our brands for the full range of equipment we service.
