We work throughout Pacifica, from Sharp Park to Linda Mar to Pedro Point, and we know these homes. Crawlspace return runs with long, tangled bends. Older sheet metal with corrosion starting at the register grilles. Whole systems that have been breathing fog-moistened air since the house was built. That’s what we clean, and we’ll show you before-and-after photos from inside your own ducts when we’re done.

Why Cardinal Air Duct Cleaning Is Pacifica’s Preferred HVAC Cleaning Company

We’re part of the Relay Home Co. family, founded in 2005, and every Pacifica booking runs on The Relay Standard: a live trackable arrival window, before-and-after photo proof, and a digital invoice you can pay from your phone. Before we touch a single duct, you get a written price. If the work isn’t right within 365 days, we return and correct it at no charge under the 365-Day Done Right Promise. Every job, no exceptions.

Our technicians are background-checked and arrive in uniform with their name on the booking, so you know who’s walking through your door. We run professional-grade equipment, including Rotobrush agitation tools and Nikro HEPA-negative vacuums, not a truck-mounted shop vac with a long hose. That matters in Pacifica, where damp, salt-sticky debris won’t release from duct walls with suction alone. It has to be agitated loose, captured under negative pressure, and removed at the source.

Omar Haddad leads our Pacifica crews. When you call, a live person answers, 24/7. Not a voicemail loop. Not a call-back tomorrow. You’ll speak to someone who can talk about your home’s duct layout, what it’ll cost, and when we can be there, all in one call.

AC Vent Cleaning in Pacifica

AC vent cleaning in Pacifica means more than wiping the register covers. Coastal fog pushes salt-laden moisture into supply and return vents year-round, and it settles inside the vent runs as a damp, sticky film. Over time, that film traps lint, dust, and pet hair, and it starts to corrode the metal. In Pedro Point and Sharp Park especially, we see register grilles crusted with a salty white residue that a paper towel won’t fix. We clean the full vent run, not just the visible faceplate.

What We Pull Out of Your Vents

Using a Nikro HEPA vacuum pulling negative pressure at the register, we extract the loosened debris straight into the collection unit. Nothing recirculates into your living room. The Rotobrush agitation tool runs through the vent run and breaks loose the damp coating that has glued itself to the duct walls. After cleaning, we photograph each vent interior with a camera and you see the result yourself on your phone.

What AC Vent Cleaning Costs

AC vent cleaning as part of a full HVAC cleaning in Pacifica typically runs $450 – $750, depending on the number of supply and return runs and whether your home has crawlspace access. We give you one flat per-system price in writing before any work starts. No per-vent math. No add-on surprises at the door.

Furnace Duct Cleaning in Pacifica

Furnace duct cleaning in Pacifica is where we earn our keep. Most homes here run gas furnaces, and the fog doesn’t stop in summer. The furnace pulls coastal air through the return ducts all year, which means the blower motor housing and the return runs collect a fine, salty grit mixed with lint. That grit is abrasive. It accelerates wear on the blower wheel and clogs the heat exchanger surfaces, and the dampness from the marine layer keeps it packed tight. A dry vac pass won’t pull it out. It takes agitation and real filtration.

The Return Run Problem

Pacifica homes, particularly in older neighborhoods like Rockaway Beach and Fairmont, often have long return runs snaking through crawlspaces. They’re damp down there, and the return ducts pull that damp air in. The result is a return-side coating of clumpy, salt-heavy debris that restricts airflow into the furnace. Restricted airflow means the furnace runs hotter and works harder than it should, which shortens its life. Cleaning the full return run with a Rotobrush agitation tool is the only way to get that coating out completely.

Furnace Duct Cleaning Cost

Furnace duct cleaning for a standard Pacifica single-furnace home runs $425 – $780. The upper end includes homes with multiple return drops, crawlspace work, or a heat pump with both supply and return ducting. We’ll give you your exact number before anyone touches a register. Written price. The number doesn’t move after we arrive.

Trusted Brands We Service in Pacifica

We service and clean around all the major brands Pacifica homes rely on: Honeywell controls, Aprilaire filtration, Carrier, Trane, Rheem, and Lennox equipment. With the coastal air here, we pay particular attention to the filtration side. Many Pacifica homes run a basic fiberglass filter because that’s what was in the slot when they moved in. We’ll tell you honestly if your system would do better with a proper MERV-rated filter from Honeywell or Aprilaire, and we stock the common sizes so we can drop one in while we’re there. No extra trip, no upcharge for the advice.

Common HVAC Cleaning Problems We See in Pacifica Homes

• Salty fog corrosion on registers and grilles. The marine layer deposits salt particles that settle on sheet metal and eat through the finish. We see this on nearly every duct cleaning job in Sharp Park and Linda Mar, and it’s a direct result of living this close to the ocean.
• Damp, clumped debris inside return ducts. Dry, dusty neighborhoods produce dry, dusty ducts. Pacifica produces damp, clumpy debris that sticks to duct walls like paste. It requires agitation-based source removal, not just vacuuming.
• Long crawlspace return runs that never get fully cleaned. Older homes in Rockaway Beach and Pedro Point often have return ducts running through tight crawlspaces. Shorter cleaning routines skip these sections. We camera-inspect and clean the full run, every time.
• Filter neglect that accelerates everything else. The foggy months make people think their systems aren’t working as hard, so filters get forgotten. A clogged filter compounds the salt and moisture problem because airflow slows and debris sticks harder. We replace filters during cleaning and tell you exactly what was in there and what it should be.
