Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.
Fast, Reliable HVAC Cleaning Across Davis
HVAC cleaning in Davis typically runs $450 – $850 for a full system clean of both furnace and AC components, and most jobs are completed in a single visit. Davis homes contend with something most California cities don’t: mineral scale from some of the hardest water in the state, which flakes off and settles inside supply registers, return drops, and coil fins. Our HVAC Cleaning team handles both the scale and the standard dust, lint, and pet dander buildup. Call (737) 727-2314 and a live person answers, 24/7.
Why Cardinal Air Duct Cleaning Is Davis’s Preferred HVAC Cleaning Company
Davis homeowners have a specific frustration with HVAC cleaning: a technician shows up, runs a brush through a few ducts, charges a price that changed from the phone quote, and leaves. That doesn’t happen with us. Every booking gets a written price before a single duct is touched, and that price does not change at the door. We clean the full system – air handler, blower, evaporator coil, supply and return ducts – not just the visible vents.
Our technicians are background-checked, uniformed, and you’ll know their name before they arrive. The Relay Standard means you get a live trackable arrival window, before-and-after photos of your own ductwork, and a digital invoice you can pay from your phone. Omar Haddad leads the team, and the 365-Day Done Right Promise applies to every job in Davis: if it’s not done right, we come back and make it right at no charge within a full year.
We work throughout Davis regularly – downtown near the UC campus, East Davis, West Davis, Wildhorse, and Mace Ranch. Dispatch is coordinated from our Sacramento office, but the crews serving Davis are local to the area and know the housing stock: older 1960s and 70s ranch homes with tight mechanical closets in Slide Hill and North Davis, newer two-story builds in South Davis with rooftop condensers, and everything between.
Furnace Cleaning in Davis
Furnace cleaning in Davis debris is a fall essential, and here’s the honest reason: your furnace pulls return air from inside the home, which means it’s sucking in whatever is already in the ducts – dust, lint, and in Davis specifically, fine mineral scale that has settled through the return drops. A full furnace cleaning in a typical Davis home runs $225 – $400 and should cover the blower motor and housing, the heat exchanger surface, the evaporator coil if it’s an AC-combined system, and the supply plenum.
What the job actually involves
Our tech removes the blower assembly, brushes and vacuums the motor housing, and cleans the fan wheel blades where dust builds up and reduces airflow. On the heat exchanger, we use compressed air and soft brushes to lift surface dust without damaging the metal. The negative-pressure vacuum stays running the whole time, so loosened debris goes into the HEPA canister, not back into your living room.
When Davis homeowners schedule it
Most Davis furnaces get used from November through March. The smart window for furnace cleaning is early fall, before the first cold week. If you’ve been running the furnace for a month and you’re noticing a musty smell or more dust than usual on the window sills, the blower and coil likely need attention now, not next season.
AC Vent Cleaning in Davis
HVAC vent cleaning in Davis goes beyond what you can reach with a household vacuum: it covers the full supply and return vent system from the grilles to the trunk lines, plus the air handler on AC-combined systems. A typical AC vent cleaning in a Davis home runs $250 – $450 depending on system size and access. To be transparent: we charge one flat price per system, not a per-vent rate that quietly multiplies on the invoice.
What the job actually involves
We remove and hand-wash each grille and register, then run a Rotobrush agitation tool through every accessible supply and return branch. The system runs under negative pressure the entire time – that’s industry language for “the vacuum is pulling air out of the duct the whole time,” so any debris we loosen gets extracted, not redistributed through the registers. The return drop gets particular attention in Davis. That’s where the mineral flake and lint collects.
How to spot it’s time
If you’ve been running the AC through July and August and you’re seeing black or grey dust streaks near the ceiling vents, that’s a sign of buildup in the supply side. If the air handler in your mechanical closet has a visible dust shell on the housing, or the blower sounds like it’s working harder than it used to, schedule a cleaning before the winter switchover. Waiting means running the furnace through a dirty coil and re-circulating that debris all fall.
Trusted Brands We Service in Davis
We service and clean all major HVAC brands, including Carrier, Trane, Lennox, Rheem, Goodman, and Mitsubishi. We stock common filter sizes and coil treatment products so Davis customers aren’t waiting on parts from a warehouse in another state. Our filtration lineup includes Aprilaire and Guardsman products when a homeowner wants upgraded media or electronic filtration after we’ve cleaned the system.
Common HVAC Cleaning Problems We See in Davis Homes
- Mineral scale in return drops and supply registers: Davis has some of the hardest water in California. Flakes from water heater and boiler flues migrate through the home and settle where airflow slows – return drops, register boots, and coil fins. A brush-only cleaning misses this.
- Dirty blower motor and fan wheel on 1960s-80s ranch homes: Slide Hill, Central Davis, and North Davis have a lot of older single-story homes with mechanical closets, not basements. Tight access means blower cleaning gets skipped by short-cut cleaners, and dust keeps cycling through the system.
- Evaporator coil coated with a mix of lint and scale: In a Davis summer, the AC runs constantly. A coil with scale and lint on the fins loses heat transfer efficiency and drives up cooling costs. It also produces that “dirty sock” odor many Davis homeowners report in August.
- Half-sealed registers after a rushed job: We see this after a cheap cleaning – the tech left the register boots loose or the filter slot is wearing a wrong MERV rating. The homeowner gets a fresh dust plume within weeks. That’s what our 365-Day Done Right Promise corrects at no charge.
Pricing for HVAC Cleaning in Davis, CA
Here are real numbers for the Davis market. A full HVAC cleaning – furnace, AC evap coil, blower, supply and return ducts – runs $450 – $850 for a typical 3-4 bedroom home. If you split it by system, a furnace-only cleaning runs $225 – $400 and an AC vent cleaning runs $250 – $450. Add-on work like a coil treatment or a Guardsman filtration upgrade is priced separately and confirmed in writing before we start. What affects the total: system size, number of return drops, and whether the air handler is in a closet or an attic.

FAQs About HVAC Cleaning in Davis
No, not every year. For most Davis homes, a full HVAC cleaning every 3 to 5 years is appropriate. The exception is a home with pets that shed heavily, recent remodeling, or a Davis-specific condition: dust and mineral scale in the returns from hard water flaking. If you can see mineral scale on the furnace filter or return grille, clean sooner. For an honest recommendation on your system, call (737) 727-2314 and we’ll ask the right questions over the phone.
The scale is removed through agitation plus negative-pressure extraction, not just brushing. We run a Rotobrush tool through the branches while the HEPA vacuum pulls continuous negative air from the trunk. That combination lifts the scale and lint and pulls it straight into the canister. Davis’s hard water means we treat this as a standard step, not an optional add-on.
It’s one flat price per system, agreed in writing before we start. We don’t charge per vent and we don’t quote a low number by phone that quietly grows once the tech is inside. The price covers the full HVAC system: air handler, blower, evaporator coil, supply and return ducts, and all registers. You’ll know the exact dollar amount before a single grille is removed.
Yes. Every Davis job under The Relay Standard includes before-and-after photo documentation of your own ductwork. You’ll see the return drop, the blower housing, and the coil before we clean and after. If you want, we’ll walk you through the photos on site. The proof isn’t optional – it’s part of the booking.
It can be. A noisy blower often means dust and scale buildup on the fan wheel, which imbalances the rotation and causes a hum or rattle. In Davis, mineral flakes from hard water can add to that buildup. We’ll remove the blower assembly, clean it, and test-run it. If the motor itself is failing, we’ll tell you and give you a written repair quote. Call (737) 727-2314 and we’ll schedule a look at it.
