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

Fast, Reliable Air Duct Cleaning Across Berkeley

Air duct cleaning in Berkeley usually runs $450 – $900 for a full residential system, and most jobs are completed in a single visit. The pre-1940 housing stock here changes everything about how that work should be done. Most Berkeley homes still have their original 1920s – 1950s sheet-metal or early flex ducting running through crawlspaces that were never sealed, never wrapped, and never designed for the filtration standards we expect today. Our crews work in these systems weekly, from the flatlands around San Pablo Avenue to the switchbacks above Grizzly Peak. If you’re noticing dust settling back on furniture within days of cleaning, or if certain rooms never reach temperature, call Nelson Briggs at Hallmark Air Duct Cleaning at (833) 467-6681.

Why Hallmark Air Duct Cleaning Is Berkeley’s Preferred Company

We’re not a generalist HVAC shop that added duct cleaning to the invoice. We’re a dedicated Air Duct Cleaning contractor, and the difference shows up in the equipment we roll out. Every Berkeley job runs on Rotobrush rotary-brush extraction paired with Nikro industrial collection, and we run Abatement Technologies negative-air units on the majority of our work here. That containment matters in Berkeley more than almost anywhere else we operate.

Our familiarity with Berkeley’s building stock runs deep. We know what a gravity-furnace conversion looks like in a 1920s North Berkeley bungalow. We know that a 1940s duplex near Ashby has different duct pathologies than a 1960s apartment building near the University. And we know that hillside homes in 94707 and 94708 present access challenges and contamination profiles that flatland crews rarely encounter. Nelson Briggs built the company around one standard: every job is meant to be a mark of quality, not a minimum-effort visit. Berkeley customers who’ve hired us consistently mention the camera inspection we run before and after every cleaning because you shouldn’t have to trust that the work happened. You should get to see it.

Air Duct Cleaning Services in Berkeley

Air Duct Cleaning Services in Berkeley begin with a video inspection of the full supply and return network, then source removal using rotary-brush agitation and HEPA-filtered negative-air containment. What we dislodge, we contain. It doesn’t get recirculated through your living room. A standard single-family home in Berkeley takes four to six hours, and we quote one flat price per system before work begins. No per-vent upcharges. No bait pricing.

Residential Duct Cleaning

For Berkeley’s wood-frame houses, we clean supply ducts, return ducts, and the plenum. Older homes often have disconnected joints in the crawlspace, so we include a basic integrity check and can quote Air Duct Cleaning in Berkeley repairs on the spot if we find gaps pulling in crawlspace air.

Commercial Duct Cleaning

Multi-unit buildings, offices, and retail spaces need scheduling that respects tenants and building hours. Our commercial teams work the same HEPA-containment standard and provide before-and-after video documentation for building files.

HVAC Duct Cleaning in Berkeley

HVAC Duct Cleaning in Berkeley means treating the entire distribution path, not just the visible registers. In our climate, that path often runs through an unconditioned crawlspace where damp winter air has been working on uninsulated metal since the Coolidge administration. The mild marine air means furnaces cycle less than inland systems, so what settles in the ducts sits there for years. Cleaning here isn’t routine vacuuming. It’s frequently a restoration job on a system that was never sealed or wrapped.

Full System Cleaning

We clean every component: supply and return ducts, registers, grilles, plenums, and the blower cabinet. Berkeley’s older furnaces often don’t have modern filtration, so the blower fan and heat exchanger carry years of accumulation that keeps circulating even after the ducts themselves are addressed.

Video Inspection

Every Berkeley job includes camera inspection before and after. You see the condition of the ducts, we identify damaged sections, and after cleaning we document the result. It turns a trust-based service into a verifiable one.

Trusted Brands We Service in Berkeley

The equipment in your Berkeley home matters to us, not just the ducts themselves. We maintain working familiarity with Honeywell and Aprilaire air quality systems, which means we can evaluate whether your current filtration is doing anything meaningful for a century-old duct run, and with Lennox in Berkeley systems as well. Many Berkeley customers run Aprilaire media filters or Honeywell bypass humidifiers, and we can integrate those into the broader question of whether your clean ducts stay clean. If you’re in Berkeley and your system includes these components, we’ll assess them as part of the whole picture rather than cleaning around them.

Common Air Duct Cleaning Problems We See in Berkeley Homes

• Rodent nests and droppings in hillside crawlspace ducts. In 94707 and 94708, original ductwork frequently runs through unlined crawlspaces that are active habitat for roof rats and deer mice. Our techs routinely find nests lodged inside return ducts, and source removal has to be thorough plus disinfection or the contamination lingers.
• Asbestos-wrapped ducts in pre-1950 homes. Many Berkeley houses built before mid-century have asbestos paper or wrap on duct sections, and some have transite flue connections. These trigger Alameda County lead/asbestos handling rules before any cleaning can begin, and a standard cleaning that ignores that requirement creates a hazard, not a fix.
• Disconnected joints and gaping seams in retrofitted additions. Dense lot-line-adjacent additions in the flatlands often have ducting that was extended on a budget. Gaps pull crawlspace air directly into the living space, which undoes any cleaning within months.
• Shared dryer vent stacks in multi-unit buildings. Berkeley has thousands of duplexes and small apartment buildings where dryer vents run through a shared stack. Lint accumulates in the run, not just the trap, and that’s a fire hazard in a wall cavity. Standard cleaning that only addresses the unit’s accessible portion misses the actual risk.
