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 Air Duct Cleaning Across Covina
Air duct cleaning in Covina costs between $450 and $900 for a typical single-family home, and the honest truth is that not every house actually needs it. Our process starts with a camera inspection, not a sales pitch. We hand you a written price for the whole system before a single duct is touched, and you get before-and-after photos of your own ducts when we’re done. Call (737) 727-2314 and you’ll reach a live person who can schedule your inspection.
We know Covina’s homes because we work in them. The 1950s and 60s tract houses near downtown have different ductwork than the newer infill along the 10, and that changes how a cleaning should be done. Omar Haddad leads our team, and he insists on one standard for every job: total visibility from booking to invoice.
Why Cardinal Air Duct Cleaning Is Covina’s Preferred Air Duct Cleaning Company
Covina homeowners tend to be direct about what they want from a trade. They want to know who’s showing up, what it costs, and whether the work was actually done. That’s why our technicians arrive in uniform, background-checked, and running professional equipment: Rotobrush agitation systems paired with Nikro HEPA-rated negative-pressure vacuums. The technician’s name is sent to you before arrival, so there’s no mystery when the van pulls up on Citrus Avenue or Badillo Street.
Our bookings run through The Relay Standard, a system built by the Relay Home Co. family, which has stood since 2005. You get a live trackable arrival window from your phone, a written price before work starts, and before-and-after photo documentation of the job. If a repair is part of the work, it carries a written guarantee and a free second visit if that repair fails. That’s the 365-Day Done Right Promise, and it applies to every booking without exception.
We don’t ask you to trust us on faith. We show you the work. That’s the difference between a company that cleans ducts and one that documents them.
Air Duct Inspection in Covina
Air Duct Inspection in Covina is where every honest job should begin, and it’s the service we recommend for any homeowner who hasn’t looked inside their ducts in years. A camera goes through the supply and return runs, and we check for construction debris, rodent activity, failed tape joints, crushed flex, and the layer of fine dust that indicates whether a cleaning is actually warranted. This is not a formality. In Covina’s older stock, we often find the return side carrying more load than the supply side, because original sheet-metal trunks were sized for gravity furnaces, not the higher-velocity blowers installed later.
A full video inspection in Covina runs $99 to $175 when booked as a standalone service. If you proceed with a cleaning, that inspection fee is credited toward the job.
Camera Inspection First, Sales Pitch Second
We don’t recommend cleaning a system we haven’t looked at. A 1990s Covina build with clean flex runs and a properly sized MERV filter often just needs a filter upgrade, not a full source-removal job. We’ll tell you that plainly, because selling you a service you don’t need is how this industry earned its reputation.
What the Inspection Report Shows You
After the camera work, you get still images and a verbal walkthrough of what we saw. You decide what happens next with a written price in hand. No pressure, no “while we’re here” add-ons.
Residential Air Duct Cleaning in Covina
Residential Air Duct Cleaning in Covina means source removal, not surface blowing. We connect a Nikro HEPA-rated negative-pressure unit to the trunk line, which pulls the loosened debris straight into the vacuum, not back into your living room. Then we run Rotobrush agitation tools through every reachable supply and return branch to break the dust and debris free before it’s extracted. The process typically takes 3 to 5 hours for a 1,500 to 2,000 square foot home, and it’s done right the first time, or we come back under the 365-Day Done Right Promise.
For homes near the downtown core, this often means more time in the return side than the supply side. Those original 1950s and 60s sheet-metal trunks with undersized returns collect dust differently than newer flex duct, and a proper cleaning has to account for that.
Full System Cleaning With Before-and-After Photos
We photograph the interior of your ducts before we start and again when we finish. You see exactly what was removed. That’s the Relay Standard, and it’s written into every booking.
The 365-Day Done Right Promise
If the work isn’t right within a full year, we return and correct it at no charge. That’s the longest-standing satisfaction window in the trade, and it covers every residential job we do in Covina.
Trusted Brands We Service in Covina
We service and clean ductwork connected to all major HVAC brands, including systems paired with Honeywell, Aprilaire, and Guardsman filtration products. Our crews carry Abatement Technologies containment units on jobs where the dirt load is heavy, which keeps dust from migrating through the house during cleaning. For Covina homeowners with Aprilaire media cabinets or Honeywell electronic air cleaners, we’ll pull and inspect the filter housing as part of the job and tell you if the filter itself is doing its job or just adding resistance. Having the right equipment, and knowing how each brand’s duct system behaves, means fewer surprises mid-job and a cleaner result at the end.
Common Air Duct Cleaning Problems We See in Covina Homes
- Construction debris from remodels. Homes near Charter Oak and along Covina Boulevard frequently show drywall dust and drywall screws in the return trunks after renovations. A camera inspection catches it before the dust keeps recirculating through the blower.
- Undersized return duct on 1950s and 60s tract homes. The original sheet-metal returns were sized for older, lower-speed furnaces. When a modern blower goes in, it pulls harder, which pulls more dust through the system and raises static pressure. The return side gets dirtier faster.
- Pet hair and dander build-up in flex duct. Newer Covina homes with flex runs and multiple pets often show hair matting at the first bend from the register. This cuts airflow room by room, and a standard filter won’t catch what’s already past it.
- Rust and moisture staining in older metal trunks. Covina’s dry summers and occasional heavy winter rain create condensation cycles in uninsulated ductwork that runs through attics. Rust flakes inside the trunk mean the duct lining is breaking down and needs evaluation, not just a quick brushing.
Pricing for Air Duct Cleaning in Covina, CA
A standard whole-system Air Duct Cleaning for a typical Covina home runs $450 to $900, depending on square footage, number of returns, and how much debris is actually inside. We charge one flat price for the entire system, agreed before we start. You will never see a per-vent price on our invoice, because per-vent pricing is how bait-and-switch operators make a $79 coupon turn into a $900 surprise once the technician is in your living room.
Older homes near the downtown citrus-packing core with original metal ductwork and undersized returns tend to run toward the higher end of that range. Newer infill construction along the 10 freeway corridor with clean flex runs often lands lower. Either way, the price you approve is the price you pay. No change at the door. Call (737) 727-2314 for a free estimate, and we’ll put the number in writing.

FAQs About Air Duct Cleaning in Covina
Most Covina homes need a full source-removal cleaning every 5 to 8 years, and that’s a real number, not a sales script. If you have pets, recent remodeling, or a 1950s-60s home with original metal ducts, you may need it sooner. If your home was built in the 1990s or later, has clean flex runs, and you run a MERV 8 or better filter, you may only need an inspection and filter check, not a full cleaning. Call (737) 727-2314 and we’ll tell you honestly which camp you’re in after a camera look.
One flat price for the whole system, agreed in writing before we start. We do not price per vent, per register, or per room. Per-vent pricing makes it impossible to compare bids fairly, and it’s the most common way Covina homeowners get surprised with a much bigger invoice than the coupon they called about.
Yes, and that’s not an add-on. The Relay Standard includes before-and-after photos of your own ducts, taken with the inspection camera. You see the debris before agitation, and you see the same duct runs after extraction. We hand you the images on the spot, and the digital invoice you pay by link includes that documentation.
We schedule Covina jobs on a booked basis, which means we can’t promise same-day service or a guaranteed dispatch window that we’d be making up. What we can promise is a live arrival window you can track from your phone once your appointment is set. A real person answers our line around the clock, so you’ll never leave a voicemail and wonder if anyone heard it.
The inspection covers the supply and return trunks, branch runs, register boxes, and filter housing. We’re looking for debris load, mold staining, failed tape joints, crushed flex, and whether the system is actually dirtied enough to justify a full cleaning. If it isn’t, we’ll say so. You get still images and a straight recommendation, plus a written price if cleaning is the right call.
Ready to find out what’s actually inside your Covina ducts? Call (737) 727-2314 for a free estimate, and you’ll talk to a person, not a phone tree. We’ll schedule an inspection, hand you a written price before anything gets touched, and show you the proof when the job is done.
