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.

Why Cardinal Air Duct Cleaning Is Hobart’s Preferred HVAC Cleaning Company
We’re part of the Relay Home Co. family, founded 2005, which means every Hobart job is held to the Relay Visibility Guarantee, even though this location is independently owned and operated. That guarantee is simple: you get a live trackable arrival window, a written price before work starts, photos of your ducts before and after, and a digital invoice you can pay from your phone. Hobart homeowners don’t have to wonder who’s coming or what the final number will be.
Our lead tech on Hobart jobs is Omar Haddad, and he runs a professional-grade fleet: Rotobrush rotary brush systems for agitation, Nikro HEPA vacuums for negative-pressure extraction, and Abatement Technologies containment units so debris doesn’t re-enter your living space. Response time to most Hobart addresses is typically one to three business days, depending on how the week’s route through the southeast King County corridor is scheduled. Dispatch and scheduling are coordinated from our Seattle office; crews serve Hobart locally and know the area well.
AC Vent Cleaning in Hobart
AC vent cleaning in Hobart homes is the part of the job most people see first: the supply and return registers, grilles, and the accessible duct runs behind them. When a Hobart homeowner notices dust streaking across walls near registers or a musty smell when the AC cycles on, the vent surfaces are usually involved. This stage is included in our full HVAC cleaning, not billed separately, and for a typical Hobart home it falls within the $425 – $700 flat system price.
One thing that surprises people: vent cleaning alone rarely solves an AC airflow problem. If the blower motor and evaporator coil are caked, clean vents won’t change much. We always inspect the full pathway, not just the part you can see from the hallway.
Registers, Grilles, and Branch Runs
We remove and clean each register, hand-wipe visible grille surfaces, and agitate the first several feet of branch ducting. In Hobart’s older rural properties, these branch runs often sit in crawlspaces that haven’t been opened in years, so we document what we find with the camera before and after.
Supply vs. Return Pathways
Most Hobart homes we see have returns that pull from a central hallway or a single large return near the furnace. Those return pathways collect far more debris than supply runs, because they carry unfiltered air back to the handler. We treat the two differently, and the photo record shows it.
Furnace Duct Cleaning in Hobart
Furnace duct cleaning in Hobart means cleaning the full duct network tied to your heating system, including the air handler interior, blower assembly, heat exchanger surfaces, and all connected supply and return runs. For Hobart homeowners on well water and septic with long driveways between properties, the furnace tends to run hard through the damp fall and winter months. That runtime pulls whatever is in the crawlspace or garage into the duct stream.
Every furnace duct cleaning here is a flat per-system price, not an hourly rate. The work includes HEPA-filtered negative-pressure extraction, which means loosened debris goes straight into the vacuum rather than back into your living room. The full job runs $425 – $700 for most Hobart homes, with the written quote locked before we begin.
Air Handler and Blower Assembly
The blower wheel and air handler cabinet are where we find the heaviest accumulation in Hobart systems, especially in homes where the furnace sits in a garage or dirt-floor crawlspace. We use compressed air and brush agitation to break the caked layer loose, then capture it with the Nikro HEPA unit. This is not a quick vacuum pass; it’s the part of the job that takes the longest and makes the biggest difference.
Heat Exchanger Surfaces
When a Hobart furnace’s heat exchanger gets coated with dust and pet hair, it runs less efficiently and can give off that burnt-dust smell on the first cold morning. For safety reasons, we inspect and clean the accessible exchanger surfaces as part of the flat system price. We do not offer combustion or gas-line work; that’s a licensed HVAC contractor’s job, and we’ll tell you straight if you need one.
Trusted Brands We Service in Hobart
We service and clean systems connected to every major furnace and AC brand found in Hobart homes, and we stock common filter sizes and Guardsman filtration products for same-visit replacement. When you book, tell us the brand and model on your equipment tag; the tech arrives knowing what he’s walking into. That applies whether you’re running a newer Carrier heat pump off Tiger Mountain Road Southeast or an older Rheem unit in a farmhouse near the Cedar River watershed. No guessing games on arrival day.
Common HVAC Cleaning Problems We See in Hobart Homes
- Long duct runs through unsealed crawlspaces. Hobart’s older rural properties often have ductwork running through vented crawlspaces where dust, rodent debris, and moisture wick through gaps in the joints. We find this in at least half the pre-2000 homes we clean here, and it’s the main reason debris returns faster than homeowners expect.
- Mixed-age equipment in the same system. Because Hobart is a patchwork of original farmhouses and recent rural-residential builds, we see a lot of systems where the furnace was replaced a decade ago but the ductwork is original. That mismatch often means flex duct sagging under its own weight, which traps debris in pockets.
- Pet hair and dander concentrated in return paths. Homes with multiple dogs or cats, common out here, build up a felt-like layer on return duct walls. It doesn’t just restrict airflow; it becomes a persistent odor source that returns in a year if the return path isn’t actually cleaned, not just vacuumed at the register face.
- Construction dust left over from new builds. In newer Hobart subdivisions near the Cedar Grove area, we regularly find drywall dust and sawdust inside ducts that were never cleaned after construction. Builders don’t always protect duct openings during sheetrock and trim work, and that dust coats every surface when the system fires up.
Pricing for HVAC Cleaning in Hobart, WA
A full HVAC cleaning in Hobart, WA runs $425 – $700 for a standard single-system home. That’s one flat price per system, agreed in writing before we start, and it doesn’t change when we’re standing in your kitchen. What moves the number within that range: the size of the home, the number of systems, the length of ductwork, and whether there’s a crawlspace or an attic run. We don’t quote per vent, and we don’t run a bait-and-switch coupon. The written quote comes before any tool leaves the truck, and if the job scope expands because we find something unexpected, we show you the camera footage and get your sign-off before proceeding. Call (737) 727-2314 for a free estimate.

FAQs About HVAC Cleaning in Hobart
No. We charge one flat price per system, not per vent, per register, or per duct run. That means the $425 – $700 quote you get for a standard Hobart home is the number on the invoice. Per-vent pricing is how duct-cleaning quotes become unpredictable, especially in Hobart homes where duct layouts vary so much from one property to the next. Call (737) 727-2314 and we’ll give you a written, flat system quote.
Every four to seven years for most Hobart homes, assuming the filters are changed regularly and there’s been no major remodeling work. Hobart’s damp fall and winter months can push that toward the shorter end if your furnace sits in a vented crawlspace or garage. If you just did a big renovation, get it cleaned once afterward; drywall dust never leaves on its own. We’ll tell you honestly if your system doesn’t need cleaning yet.
Yes. Every Hobart job includes before-and-after camera photos of your own ducts, not a generic set from another house. You’ll see the supply runs, the return pathway, the blower assembly, and the coil surfaces before we start and after we finish. The photos arrive with your digital invoice, viewable from your phone. That’s part of the Relay Standard on every booking.
No, and for a reason. A proper HVAC cleaning takes three to five hours on site, plus setup and containment. Rushing it to fit a same-day promise means cutting corners on camera inspection, negative-pressure setup, or blower cleaning. We schedule Hobart jobs one to three business days out most weeks, and we give you a live trackable arrival window so you’re not waiting around on a four-hour promise.
NADCA is the National Air Duct Cleaners Association, and their standard is the industry benchmark for source removal: agitate the debris, capture it with negative pressure, and document the result. We follow that standard on every Hobart system we clean, using Rotobrush agitation and Nikro HEPA extraction. It’s not a marketing badge we put on the website; it’s the actual method our techs, led by Omar Haddad, use on every job.
If your Hobart home’s ducts haven’t been inspected in years, or you’re seeing dust blow from the registers every time the heat kicks on, call (737) 727-2314. You’ll get a straight answer, a written flat price, and photos of your own system before and after. That’s the whole job.
