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.

AfterFast, Reliable Air Duct Cleaning Across San Dimas
Air duct cleaning in San Dimas typically runs $450 – $850 for a full residential system, and most jobs are completed in four to six hours with one flat price agreed before we enter your home. We serve the entire city: Bonita Avenue, San Dimas Canyon Road, the homes around San Dimas High School and Lone Hill Middle School, 91773. Our crews grease no palms at HOAs – we simply show up on schedule with written pricing and professional equipment, clean what you paid for, and send before-and-after photos. If your registers have started dusting your furniture within days of cleaning, or if the return boot behind your air handler is carrying visible grit every time you slide the filter out, give Omar Haddad’s team a call at (737) 727-2314. We know foothill ductwork and we know what these systems collect.
Why Cardinal Air Duct Cleaning Is San Dimas’s Preferred Air Duct Cleaning Company
San Dimas sits hard against the San Gabriel Mountains. That is not a postcard detail; it is a ductwork fact. The same wind that keeps Puddingstone Lake choppy pushes fine, abrasive grit off the foothills and into the return side of your HVAC system. We see it weekly. Many companies that service San Dimas actually dispatch from flatland offices and treat this city like any other inland suburb. We know better. Our technicians understand the pressure imbalance that foothill homes create and where debris actually packs in. Reviews from San Dimas homeowners repeatedly mention the same two things: we arrived when we said we would, and the price on the written quote matched the final invoice. That is not a trick – it is the standard Omar Haddad builds every San Dimas booking around. We run Rotobrush agitation tools and Nikro HEPA extraction units, not a shop vac bolted to a truck. You can track the live arrival window on your phone before we get to your street. A real person at (737) 727-2314 answers your call without a phone tree.
Air Duct Inspection in San Dimas
Air Duct Inspection in San Dimas is what we recommend before anyone starts quoting you a cleaning price. A camera inspection of the return boot, supply trunk, and farthest register runs $149 and takes about an hour. It tells you what is actually in there: windblown San Dimas grit, pet dander, construction dust from the 1970s and 80s builds near Via Verde, or sometimes very little at all. If your ducts are clean, we will tell you and recommend you save your money. Honest work, in this trade, means refusing paying jobs sometimes. The inspection gives you the evidence to decide.
Camera Inspection of the Return Boot
This is where San Dimas systems fail first. The return boot behind the air handler is the low point in the airflow path, and in foothill homes it collects far more than the supply side. We insert a camera probe through the filter slot or an access panel and show you the live feed on a tablet. You see the same buildup we see.
Whole-Duct Video Walkthrough
After the boot, we run the camera down each main trunk and representative branch lines. We look for separated duct sections, rodent entry points, water staining, and compressed flex duct. You get still images from the footage, date-stamped for your records.
Residential Air Duct Cleaning in San Dimas
Residential Air Duct Cleaning in San Dimas for a typical 1,500 to 2,500 square foot single-family home runs $450 – $850 depending on how many returns and supply runs the house has. That is a flat price per system, not per vent. You receive the written number before we start, and it does not change at the door. For larger homes in the hills above San Dimas Avenue or custom builds near Frank G. Bonelli Regional Park, we quote by the footage and number of runs. The job takes most of an afternoon: we cap each register, connect our Abatement Technologies negative pressure unit to the main trunk, and work the full interior of both the supply and return sides with Rotobrush agitation tools. The loosened debris goes directly into the HEPA-filtered vacuum, not back into your living room.
Full Supply and Return Cleaning
Most San Dimas homes have 8 to 14 supply runs and two to four return drops. We clean every one. No skipping the far guest bedroom because the company wants to finish in 90 minutes. Our written quote lists every run we will clean, so you can check the work register by register.
Air Handler and Blower Cleaning
San Dimas foothill dust does not just sit in the ducts. It migrates into the blower motor fins, the evaporator coil, and the air handler cabinet itself. A duct cleaning that skips the air handler is a half-done job. We remove the blower assembly, clean the motor and wheel, and wash the accessible coil surfaces. This is the part most discount crews quietly omit, and it is the part that decides whether your system breath easy or keeps circulating grit.
Trusted Brands We Service in San Dimas
Our equipment works on all standard residential duct systems in San Dimas, regardless of the hardware brand. We clean and service systems built around Aprilaire filtration housings, Guardsman purifiers, and Honeywell controls. We stock common San Dimas replacement sizes: 16×25, 20×25, and 16×20 filter frames, flexible duct in 6 to 12 inch diameters, and grilles to match the register styles common in 1970s and 80s San Dimas construction. The brands we carry in our vans mean we do not have to make a second trip for common parts. That is the standard we hold across our Air Duct Cleaning work in this city.
Common Air Duct Cleaning Problems We See in San Dimas Homes
- Foothill grit in the first return boot. The inland position at the base of the San Gabriel Mountains funnels wind-driven dust and debris off the foothills into return ducts. The first return boot behind the air handler in San Dimas regularly carries far heavier grit loads than homes a few miles west in Glendora or Covina.
- Pet hair packed around the blower motor. The majority of San Dimas homes we open have had at least one dog or cat inside for years. Hair wraps the blower wheel, reduces airflow, and forces the system to run hotter and longer. It is not a duct issue until the hair becomes a duct issue.
- Discount crews skipping the air handler and blower. Contractors quote a low price per vent but skip the air handler, blower motor, and return boot – the exact places San Dimas foothill grit and lint accumulate most heavily. The register drops get a quick brush and the customer gets a bill but not a cleaning.
- Collapsed or disconnected flex duct in attics. San Dimas summers push attic temperatures past 130 degrees. Flexible duct in older homes can separate or crush. We find these during camera inspections and can spot-replace sections before they leak cool air into the attic for another season.
Pricing for Air Duct Cleaning in San Dimas, CA
A standard full-system air duct cleaning in San Dimas runs $450 – $850 for a home up to 2,500 square feet. The price is flat per system and written before work starts. It covers every supply run, every return drop, the air handler and blower, and a final live-walkthrough of your registers with before-and-after photos. For a home above 2,500 square feet, or one with more than four returns, expect the quote to land between $850 and $1,200. Camera inspection is $149 and folds into the cleaning price if you proceed. The two honest variables are square footage and the number of runs – not the salesman’s mood. Call (737) 727-2314 and give our team three minutes on the phone. You will have a written estimate before the end of the day.

FAQs About Air Duct Cleaning in San Dimas
Most San Dimas homes with a single pet and no history of construction or water damage genuinely need a full duct cleaning every 3 to 5 years. Homes with multiple pets, homes adjacent to open foothill space, or homes that have been through a remodel should inspect every 2 years. If your return boot has never been opened and the house is 20 years old, you likely need at least a camera inspection now. Call (737) 727-2314 for a straight answer on your specific system.
No. We charge one flat price per system, agreed before work begins. We do not price per vent, we do not add charges once the technician arrives, and the written number we send you is the number you pay. The flat price covers every supply run and every return in the home, plus the air handler and blower motor. Call (737) 727-2314 and we will give you a real quote over the phone, free.
We cap each register, connect a HEPA-filtered vacuum unit to the main trunk to set the system under negative pressure, and work the interior of every duct run with rotary agitation tools. The loosened debris is pulled directly into the vacuum containment, not blown back into your living room. Then we clean the blower motor, wheel, and air handler cabinet, which most low-ball crews skip entirely. The job takes four to six hours on a typical San Dimas home.
Yes. Every booking includes before-and-after photos of your own ducts and registers. You see the return boot before we start and you see it after we finish. In one Via Verde home, a 22-year-old system was cycling on high-limit because the return boot behind the air handler was packed with windblown grit and pet hair. Our photos showed that boot going from black to bare metal. If you cannot verify the work, you have no reason to trust the invoice. We make verification standard on every job in San Dimas.
Sometimes, but we do not promise same-day service because we do not run a rush-and-go operation. Air duct cleaning is a scheduled job that takes four to six hours on a normal San Dimas home. What we do promise is a live arrival window you can track on your phone, a real person answering at (737) 727-2314, and a written price before any work starts. If we have a slot open, we will tell you. If not, we will tell you when we can be there and we will actually arrive then.
