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 Boyes Hot Springs’s Preferred HVAC Cleaning Company
We’re part of the Relay Home Co. family, founded in 2005, and we operate under The Relay Visibility Guarantee. That means every booking in Boyes Hot Springs includes a live trackable arrival time, before-and-after photos of the actual work, and a digital invoice you can pay from your phone. No four-hour windows. No wondering who’s showing up. Our technicians are background-checked and arrive in uniform, and you’ll know the tech’s name before they ring the bell.
Omar Haddad, our owner, has built the Boyes Hot Springs operation around transparency. The 365-Day Done Right Promise applies to every job here without exception: if the work isn’t right within a full year, we return and correct it at no charge. We also put a written guarantee on every repair, with a free second visit if that repair fails. Homeowners around Boyes Boulevard, Fetters Hot Springs, and Agua Caliente have told us the same thing: they’re tired of vague estimates and pricing that shifts once a technician is inside. We operate differently because the standard in this trade is too low, and Boyes Hot Springs deserves better.
AC Coil Cleaning in Boyes Hot Springs
AC coil cleaning in Boyes Hot Springs is one of the most frequent calls we get, especially in August when the evaporator coil has been running full tilt for months and the system just can’t keep the house below 80 degrees. The job involves pulling the coil access panel, inspecting the evaporator and condenser coils, and removing the caked-on dust and film that strangulates heat transfer. In Boyes Hot Springs specifically, summer heat lingers in the valley bowl, so AC systems run longer cycles than coastal homes, which means coils here collect more debris in a single season.
Evaporator Coil Cleaning
The evaporator coil sits inside the air handler and absorbs heat from your indoor air. When it’s coated with dust and pet hair, your system runs longer to hit the same temperature, pushing up your PGE bill. A typical evaporator coil cleaning in Boyes Hot Springs runs $180 – $240 as a standalone service, or it’s bundled into a full HVAC cleaning at a better value.
Condenser Coil Cleaning
The condenser coil lives outside in the unit by your house, and in Boyes Hot Springs it takes a beating from cottonwood fluff, dust kicked up from unpaved driveways off Lovall Valley Road, and grass clippings. We clean it with a low-pressure rinse and coil-specific cleaner. Expect $120 – $190 for condenser coil cleaning as a separate job.
AC Cleaning in Boyes Hot Springs
AC cleaning in Boyes Hot Springs means cleaning the entire air conditioning side of your HVAC system: both coils, the blower wheel, the blower housing, the condensate drain line, and the air handler cabinet. We recommend it when you’re seeing dust accumulate on registers, noticing weak airflow, or when the system has cycled through a smoky wildfire season or a winter of fireplace use without any professional attention. A full AC cleaning in Boyes Hot Springs runs $350 – $520 depending on system accessibility and how much buildup we’re dealing with.
Blower Cleaning
The blower wheel moves air through your entire house, and if it’s caked with dirt, it moves less air while pulling more electricity. We remove the blower assembly, clean each blade, and clean the housing so air actually flows the way the system was designed to. Blower cleaning as a standalone service runs $150 – $220 in Boyes Hot Springs.
Air Handler Cleaning
Older Boyes Hot Springs homes, especially the 1940s and 1950s builds off Boyes Boulevard, often have air handlers tucked into tight closets where dust and debris collect for years undisturbed. We clean the cabinet interior, the condensate pan, and the drain line, which prevents the mildew smell and water damage that follow a clogged drain. Air handler cleaning typically runs $180 – $260.
Trusted Brands We Service in Boyes Hot Springs
Our crews run professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, not truck-mounted shop vacs. The Nikro HEPA-filtered negative air system captures the dirt we dislodge instead of pushing it back into your living room, and the Rotobrush agitation system breaks up packed debris inside the ductwork before extraction. We also service and install filtration products from Honeywell, Aprilaire, and Guardsman, which matters in Boyes Hot Springs where fine particulate from wood burn and wildfire smoke makes good filtration a real health consideration. Parts for the major brands are stocked locally for our Bay Area dispatch, so if we find a chipped blower blade or a torn filter rack during cleaning, you’re not waiting a week for a part to ship.
Common HVAC Cleaning Problems We See in Boyes Hot Springs Homes
- Smoke residue in supply ducts. Winter inversions trap wood-smoke particulate in the valley, and homes with fireplaces or wood stoves pull that fine residue into the return and push it back out through supply registers. We see a gray film inside ducts here more than nearly any other part of Sonoma County.
- Retrofitted systems with mismatched duct layout. Many Boyes Hot Springs homes were built before central AC, then retrofitted decades later, leaving air handlers in closets and duct runs that don’t match the original floor plan. Without a camera inspection first, a cleaner can miss entire sections of disconnected or collapsed ductwork.
- Lint and debris packed around the air handler cabinet. When the air handler sits in a utility closet or garage, household lint, dust, and even pest debris collect around the cabinet and get pulled through the system. In older homes, that buildup can be thick enough to reduce airflow by half.
- Clogged condensate drain lines from mineral-heavy water. The water here carries a fair amount of mineral content, and over a season that leads to scale buildup in the drain line. A clogged line backs up into the air handler pan, which creates the damp smell homeowners describe as a musty odor.

FAQs About HVAC Cleaning in Boyes Hot Springs
How do you decide if my Boyes Hot Springs home actually needs HVAC cleaning?
We run a camera inspection through your ductwork before recommending anything. In Boyes Hot Springs homes built before the 1970s, we often find the ducts have never been opened since installation, so there’s no way to know what’s inside without looking. If the camera shows light dust, we’ll tell you honestly that cleaning can wait. If it shows packed debris, smoke residue, or mold growth, we’ll show you the footage and quote one flat price per system. No pressure, no phone call the next day to upsell you.
Do you charge by the vent or by the system?
By the system. Per-vent pricing is how homeowners in Boyes Hot Springs get burned, because a house off Boyes Boulevard with a retrofitted HVAC system can have 14 registers where the original floor plan had 8, and the crew counts every one. We quote a flat per-system price before we start, and it does not change no matter how many registers we find. Call (737) 727-2314 with your home’s rough square footage and we can give you a tighter range over the phone.
What does the cleaning process actually involve?
We start with a camera inspection, then set up negative-pressure extraction, which means the debris we loosen gets pulled directly into the HEPA-filtered vacuum instead of back into your living room air. We agitate the duct walls to break up the packed layer, clean the evaporator coil and blower wheel while the system is open, and then take before-and-after photos so you can see the work was actually done. The whole job usually takes 3 to 5 hours for a standard Boyes Hot Springs home.
How often is HVAC cleaning genuinely needed in Boyes Hot Springs?
For most homes here, every 3 to 5 years is the honest answer. Homes that run the AC constantly during the valley’s hot summers, use a fireplace regularly, or have pets and older ductwork may need it closer to every 2 to 3 years. If you’ve just finished a remodel off Lovall Valley Road or replaced your flooring, the construction dust alone justifies a full cleaning sooner. We’ll tell you if you don’t need it yet, because a job done honestly is worth more to us than one done often.
Can you come out the same day I call?
We can’t promise same-day service, because proper HVAC cleaning in Boyes Hot Springs is a scheduled job that requires careful work with professional equipment, not a rushed half-hour visit. What we can promise is a live person on the phone at (737) 727-2314, a trackable arrival window through The Relay Standard, and a written price before any work begins. If your system has stopped working entirely, tell us when you call and we’ll work with you on the soonest available appointment.
