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.

Call (737) 727-2314 and we’ll give you a written price before anyone touches a single duct.
That price is the whole point. No per-vent pricing, no surprise line items once the blower is open, no bait quote that triples at the door. You get one flat price per system, agreed to in writing, and before-and-after photos of your own duct runs when we finish.
Why Cardinal Air Duct Cleaning Is San Jacinto’s Preferred HVAC Cleaning Company
Cardinal Air Duct Cleaning is the air duct specialist in the Relay Home Co. family, founded 2005, and every San Jacinto booking runs through The Relay Standard. That means you get a live arrival window you can track from your phone, a uniformed tech whose name you know before they knock, and a digital invoice you can pay by link. The 365-Day Done Right Promise applies to every job we do here, no exceptions: if the work isn’t right within a full year, we come back and correct it at no charge.
Our crews carry Rotobrush rotary brush systems and a Nikro HEPA vacuum set up for negative-pressure extraction, which means the loosened debris goes straight into the vacuum, not back into your living room. We also carry Abatement Technologies containment units for homes with older return plenums or tight attic access. Omar Haddad leads our team, and every technician is background-checked and arrives in uniform. Calls are answered by a live person, not a voicemail loop.
San Jacinto homeowners have a specific set of complaints by the time they call us: gray dust on vents, weak airflow in mid-summer, a blower that sounds like it’s working harder than it should. We’ve cleaned systems in every part of this valley, so we know what a 14-year-old air handler off Cottonwood Avenue looks like versus a five-year-old unit in a newer build near the Soboba Casino corridor. That matters when you’re deciding whether a cleaning is worth it or whether something else is going on.
Furnace Duct Cleaning in San Jacinto
Furnace Duct Cleaning in San Jacinto means pulling the accumulated dust, pet dander, and pollen out of the full supply and return duct runs, the air handler, and the blower assembly. Even though San Jacinto rarely sees hard freezes, winter mornings in the valley still dip into the 40s, and every heating cycle pushes warm air through whatever has settled in those ducts since the spring. Our HVAC Cleaning team cleans the furnace ductwork using source-removal methods: agitation brushes combined with negative-pressure HEPA extraction, never just a shop vac at the register.
A furnace duct cleaning in San Jacinto typically runs $450 – $650 depending on the number of returns and the length of trunk line. Homes with a single return and a compact single-story footprint fall on the lower end; older two-story homes or properties with long supply runs toward the garage fall higher.
Full Source Removal, Not Blowing Dust Around
We clean the metal from the inside, not the surface. The brush agitates the dust caked to the duct walls, and the Nikro HEPA vacuum pulls it out under negative pressure. The dust never re-enters your home.
Blower And Return-Side Attention
Furnace cleaning is incomplete if the blower motor and return plenum are skipped. In San Jacinto homes, return-side dust is the heavier load, so we open and clean the return boots and the blower wheel as part of the flat per-system price.
AC Coil Cleaning in San Jacinto
AC Coil Cleaning in San Jacinto is usually the single highest-impact step for a system that runs hard from May through October. When valley temperatures push well past 100°F, the evaporator coil is doing the only work that matters, pulling heat and humidity out of the air. A coil caked with fine gray dust starves the system of airflow and drives electric bills up. We clean the evaporator coil, the condenser coil, and the blower assembly as one job, and the price range is $350 – $700 depending on access and coil condition.
If you’re near Hemet border or off the Ramona Expressway corridor where newer builds sit exposed to open field dust and Santa Ana wind events, expect heavier coil fouling than older, tree-shaded lots near downtown. That’s not a guess, it’s what we see when we open the air handler.
Evaporator Coil Inspection And Cleaning
We pull the access panel, camera-inspect the coil, then clean it with the correct coil-safe process. If the coil is matted, we’ll show you the before photo before we start. You’ll see the after photo when we’re done.
Condenser And Coil Treatment
The outdoor condenser gets a full fin cleaning and a coil treatment that slows dust re-adhesion through the summer. In San Jacinto’s dry heat, a treated coil stays cleaner longer than an untreated one.
Trusted Brands We Service in San Jacinto
Our technicians work on every major HVAC brand installed in San Jacinto, from Trane and Carrier to Lennox, Rheem, Goodman, and Bryant. We carry common filters in standard MERV ratings and stock parts for the brands we see most often, which usually trims a repair or replacement into a single-visit job. We service Honeywell, Aprilaire, and Guardsman filtration products, so whatever filter cabinet is mounted in your closet or attic, our team can service and replace it correctly. No need to wait on a third-party supplier or get bounced between a duct cleaner and an HVAC contractor.
Common HVAC Cleaning Problems We See in San Jacinto Homes
- Heavy gray dust accumulation from valley wind events. The same Santa Ana winds that push summer temps past 100°F also drive fine dust and pollen into return-side gaps, and the load we pull here runs noticeably finer than in coastal cities. It settles into the blower motor and coil faster than most homeowners expect.
- Clogged filters due to San Jacinto’s dusty season. A 1-inch filter on an older return grille clogs fast in this valley. We see Aprilaire and Honeywell media cabinets packed solid with gray dust, often several months past a reasonable change interval.
- Restricted airflow from improperly sized or mismatched filter replacements. A cheap, high-MERV filter can starve a San Jacinto blower motor, especially on older single-speed systems. We check static pressure and ensure the filter you have isn’t killing your airflow.
- Dirty coils and blower assemblies from long run cycles. Because San Jacinto systems run nearly year-round, dust bakes onto the evaporator coil and blower wheel. This shortens system life and raises cooling costs all summer long.

FAQs About HVAC Cleaning in San Jacinto
Most San Jacinto homes need a full HVAC cleaning every 3 to 5 years, and some need it sooner. The valley’s dry heat, fine valley dust, and long cooling season mean systems here accumulate dust faster than in coastal or mountain homes. If you have pets, live near open fields, or run your system year-round, aim closer to every 2 to 3 years. Call (737) 727-2314 and we’ll talk through what you’re seeing at the registers.
We price per system, never per vent. A per-vent price punishes San Jacinto homes with long supply and return duct runs, which are common in this valley. You get one flat price per system in writing before work starts, and it covers the full air handler, coils, blower, and duct runs. No surprise line items, no door-knock upsell.
We start with a camera inspection of your air handler, coils, and duct runs. Then we use rotary agitation brushes to loosen dust and a Nikro HEPA vacuum under negative pressure to pull it out. The loosened dust goes straight into the vacuum, not back into your living room. After cleaning, we reassemble everything and hand you before-and-after photos of your own ducts. A typical San Jacinto home takes one visit, usually a few hours.
Yes. Every San Jacinto job includes before-and-after photo documentation of your own duct runs, coils, and blower assembly, delivered through the same digital link as your invoice. The photos are of your actual system, not a stock image. That’s part of The Relay Visibility Guarantee on every booking.
We don’t promise same-day service, because a proper HVAC cleaning in San Jacinto is a scheduled job, not an emergency dispatch. What we do promise is a live arrival window you can track from your phone, so you aren’t sitting around for four hours wondering if anyone is coming. Call (737) 727-2314 and we’ll get you on the schedule for the next available slot.
