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.

HVAC cleaning in East Palo Alto typically runs $425 to $875 for a full system on a single-family home, and most jobs are completed in one visit. That’s the honest range before we see the ductwork.

Call (737) 727-2314 and a live person answers, 24/7.
What makes East Palo Alto different from every other city on the Peninsula? The housing stock. We’ll get into that below, but the short version is this: older ranch homes and apartment buildings with retrofit duct runs need a specific kind of cleaning, and most companies do the wrong thing. We do the right thing, document it with photos, and stand behind it for a full year.
Why Cardinal Air Duct Cleaning Is East Palo Alto’s Preferred HVAC Cleaning Company
East Palo Alto homeowners call us after they’ve already had a frustrating experience elsewhere, or because they’re tired of phone quotes that don’t match the final invoice. We run The Relay Standard on every single job: a live trackable arrival window, before-and-after photos of your own ducts, and a digital invoice you pay from a link. No ambiguity, no guessing.
Omar Haddad leads our team, and he’s built the East Palo Alto service area around one principle: the price we write down before work starts is the price you pay. That’s not a slogan. It’s the operational reality of every booking. If you live near Cooley Landing or over by Bell Street Park, the technician you meet will be background-checked and uniformed, and their name is on your confirmation before they arrive.
We run professional-grade equipment on every job: Rotobrush rotary brush systems for agitation, Nikro HEPA vacuums for negative-pressure extraction, and Abatement Technologies containment units where the ductwork demands it. This matters in East Palo Alto specifically, where tight retrofit runs in attics and crawlspaces push a lot of companies to cut corners. We don’t.
Every HVAC cleaning in East Palo Alto carries our 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 satisfaction window in the trade, and it applies to every job, no exceptions.
AC Cleaning in East Palo Alto
AC cleaning in East Palo Alto is usually the first thing a homeowner needs when cooling season starts and the registers are blowing weak or smelly air. On older ranch homes east of Bayshore Freeway and the smaller apartment buildings near University Avenue, dust and debris accumulate inside the supply side of the system, which forces the blower to work harder and pushes particulate back into living spaces. A full AC cleaning here means cleaning the return and supply ducts, cleaning the evaporator coil, and finishing with a coil treatment that slows future buildup. Expect to pay $350 to $650 for a standard AC cleaning on a single-story East Palo Alto home.
Pre-Season Tune-Up Work
Before East Palo Alto’s summer heat, homeowners near Jack Farrell Park and Pioneer Park often schedule an AC cleaning combined with evaporator coil cleaning. This is when systems that haven’t run since the previous year dump their accumulated dust load all at once. The coil gets caked first, and when that happens, cooling efficiency drops fast. We inspect the coil with a camera before recommending whether cleaning alone is enough or whether the full duct run needs source removal.
Post-Renovation Cleaning
East Palo Alto has seen a steady stream of renovation and remodeling work, especially around Clarke Avenue and the redevelopment areas off 101. Drywall dust, construction debris, and paint overspray get sucked into return ducts and settle inside short retrofit runs that were never built for that kind of abuse. We do a deep clean on both supply and return sides, then verify with camera footage that the runs are actually clear before we pack up.
Evaporator Coil Cleaning in East Palo Alto
Evaporator coil cleaning in East Palo Alto is the single highest-impact job we do for cooling efficiency. The evaporator coil sits inside the air handler, and on older systems in East Palo Alto, it’s frequently coated in a thick paste of dust and condensation by August. A dirty coil reduces heat transfer, raises energy bills, and shortens compressor life. Coil cleaning alone runs $225 to $400 depending on the size of the system and how accessible the coil is. If it’s paired with full duct cleaning, the coil work is typically priced as part of the flat per-system quote, not as an add-on surprise.
Coil Inspection and Treatment
Before we clean an evaporator coil in an East Palo Alto home, we inspect it with a borescope camera so you can see what we see. Then we clean it with professional-grade coil cleaning solutions, flush the drain line, and apply an antimicrobial coil treatment to slow regrowth. This is the job that fixes the “musty smell when the AC kicks on” complaint we hear all the time in this city.
When a Coil Clean Isn’t Enough
Some coils in East Palo Alto are so old and corroded that cleaning them is a band-aid. If our inspection shows deep pitting or refrigerant leaks, we tell you honestly rather than selling you a clean that won’t hold. The camera footage is yours to keep, and you’ll know exactly what condition the coil is in before you spend a dollar on service.
Trusted Brands We Service in East Palo Alto
East Palo Alto’s HVAC installations span decades, and we regularly service and clean systems from every major brand you’ll find here: Trane, Carrier, Lennox, Rheem, Goodman, and York. Because we stock parts for the most common configurations in East Palo Alto homes, turnarounds are shorter than they’d be if we had to order everything from a distributor. When we install filtration products, we use Honeywell, Aprilaire, and Guardsman components. And for the cleaning itself, we don’t show up with a shop vac. The Rotobrush rotary brush systems and Nikro HEPA units are built for exactly this work, and they’re on every truck.
Common HVAC Cleaning Problems We See in East Palo Alto Homes
- Retrofit duct runs with tight bends and non-standard sizing. East Palo Alto’s older homes were often built before central HVAC, so ductwork was added later, sometimes routed through impossibly tight attic and crawlspace paths. Debris collects in those bends, and a surface blow-through won’t get it out. Source removal with camera verification is the only honest fix.
- Dust on registers within days of a “cleaning” done elsewhere. This is the signature failure of companies that push compressed air through ducts instead of extracting debris under negative pressure. The dust gets moved around, not removed. We hear this constantly from East Palo Alto homeowners who paid a low per-vent price and got nothing for it.
- Musty odor from the air handler when cooling starts. This is almost always an evaporator coil caked with biological growth and dust. It’s common in East Palo Alto because of the humidity the bay brings in mornings and evenings. A coil clean with antimicrobial treatment solves it.
- No proof the job was actually done. Homeowners in East Palo Alto tell us they’ve had technicians climb into an attic for 40 minutes and hand over an invoice with no documentation. The Relay Standard requires before-and-after photos of your ducts on every job, and we won’t run a booking without them.

FAQs About HVAC Cleaning in East Palo Alto
Every 3 to 5 years for most homes, and sometimes sooner if you’ve done remodeling, have persistent allergy symptoms, or notice visible dust accumulating on registers within days of wiping them. East Palo Alto’s older housing stock, with retrofit duct runs and tight attic clearances, tends to collect debris faster than newer construction. If your system is newer and you change filters regularly, you may not need cleaning for 5 years or longer. Call (737) 727-2314 and we’ll talk honestly about whether cleaning is actually needed on your system.
Because per-vent pricing is a quote structure, not a service. Companies that price per vent in East Palo Alto are often low-balling you over the phone and then inflating the invoice once the technician is on-site. We give you a written price for your entire system before any work begins, and that price does not change at the door. No per-register math, no per-run surcharges. One flat price per system. Call (737) 727-2314 for a free written estimate.
Source removal means the debris inside your ducts is physically loosened and extracted under negative pressure, not just blown around with compressed air. On older East Palo Alto homes with retrofit runs and tight bends, a blow-through often pushes debris toward the air handler and blower motor rather than removing it. We use Rotobrush agitation tools with Nikro HEPA vacuum extraction, then verify the ducts are actually clear with camera footage. You see the before and after.
Yes, every job. Before-and-after photos of your own ductwork are part of The Relay Standard and included in every booking. You’ll see the returns and supply runs as they were when we arrived and as they are when we leave. No other duct cleaning company in East Palo Alto offers this as a standard on every job.
We don’t promise same-day service. HVAC cleaning is a scheduled job, and doing it right takes time we won’t compress to hit a dispatch window. What we do offer is a live trackable arrival window on the day of your booking, and scheduling that works around your life in East Palo Alto. Call (737) 727-2314 and our team will find the earliest slot that actually works, not the fastest one we can fake.
