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 East Palo Alto
Air duct cleaning in East Palo Alto typically costs $425 – $850 for a standard single-family home, and most jobs wrap up in 4 – 7 hours. We work on the ranch homes and small apartment buildings that fill the Weeks, Gardens, and University Square neighborhoods, so we know exactly what’s inside those attic runs and return plenums.

Why Cardinal Air Duct Cleaning Is East Palo Alto’s Preferred Air Duct Cleaning Company
We’re the air duct specialist in the Relay Home Co. family, founded in 2005 and built around one principle: total visibility from booking to invoice. That means you know the technician’s name before they arrive, you get a live trackable arrival window, and you receive before-and-after photos of your own ducts. No other duct cleaner in East Palo Alto operates under that standard. Our technicians are background-checked, uniformed, and carry professional-grade equipment: Rotobrush rotary brush systems for agitation, Nikro HEPA vacuums for negative-pressure extraction, and Abatement Technologies containment units when the job calls for it. Omar Haddad, who leads our East Palo Alto operations, insists on the 365-Day Done Right Promise for every booking, no exceptions. If the work isn’t right within a year, we return and correct it at no charge. That’s not a sales pitch. It’s the Relay Standard, and it covers every job in East Palo Alto.
We answer calls with a live person, 24/7. No voicemail loops. No phone tag. When a homeowner on Daphne Way or a property manager on East Bayshore Road calls, they get a straight answer about scheduling and pricing immediately.
Residential Air Duct Cleaning in East Palo Alto
Residential Air Duct Cleaning in East Palo Alto usually involves the full supply and return duct system, not just the visible register openings. In a mid-century ranch on the flat grid streets east of Highway 101, that means accessing the attic, inspecting the main trunk line and metal laterals, and removing years of accumulated fine dust, pollen, and the occasional tenant’s lint. Most standard single-family homes here run $425 – $650. Larger two-story homes or properties with heavily soiled systems run $650 – $850. The price is one flat rate per system, agreed in writing before work begins.
Single-family homes and older ranch layouts
East Palo Alto’s housing stock skews toward post-war ranches with long, shallow attic runs. These systems trap debris in the return side first, which is where we focus our camera inspection before any cleaning starts. The goal is source removal: loosening and extracting the debris at its origin, not just vacuuming what’s visible at the register.
Apartments and small multi-unit buildings
Many East Palo Alto renters live in four- to eight-unit apartment buildings with shared or adjacent duct runs. We clean those systems with containment setups from Abatement Technologies so debris from one unit doesn’t migrate into the next. Property owners get before-and-after photos for each unit, which makes move-out turnovers faster to document.
Commercial Air Duct Cleaning in East Palo Alto
Commercial Air Duct Cleaning in East Palo Alto covers the small retail shops, offices, restaurants, and medical suites that run along University Avenue, East Bayshore Road, and the light-industrial blocks near the 101. These spaces often have drop ceilings, rooftop HVAC units, and duct layouts that haven’t been touched since the building went up. A typical small commercial space under 2,500 square feet runs $650 – $1,200 depending on the number of rooftop units and the length of duct runs. Larger single-story commercial buildings run $1,200 – $2,800. Every quote is one flat price per system, written before any work starts.
Retail and office spaces
Retail storefronts on University Avenue deal with constant foot traffic, which means more dust, more frequent filter changes, and faster buildup on blower assemblies. We schedule commercial work around operating hours so there’s no disruption to customers or staff.
Restaurant and food-service kitchens
Restaurants in East Palo Alto contend with grease-laden air that deposits on duct walls and reduces airflow. We’ll recommend the right filtration, typically Aprilaire media filters, after the cleaning is done. The 365-Day Done Right Promise applies to commercial work exactly as it does to residential.
Trusted Brands We Service in East Palo Alto
We service and clean systems using any major brand, and we stock replacement filters for Honeywell, Aprilaire, and Nikro at our Bay Area dispatch center. That means when we finish a cleaning and recommend a new MERV 8 or MERV 11 filter, you won’t wait a week for it to arrive. Our Nikro HEPA vacuums handle fine particles down to the level that cheaper shop-vac setups simply miss, and our Rotobrush agitation systems reach the full length of the duct run in East Palo Alto’s shallower attic spaces. We don’t cut corners on equipment because the Baylands dust in this city doesn’t respond to half-measures.
Common Air Duct Cleaning Problems We See in East Palo Alto Homes
- Fine silica dust from the Baylands and Highway 101. East Palo Alto sits between the freeway and the bay, and the dry months pull a constant stream of fine dust into return plenums. This dust is far smaller than typical household dust, so it passes through standard fiberglass filters and settles deep in the ducts.
- Clogged blower motors that never get cleaned. On older ranch homes, the blower motor sits downstream of the filter, so any bypass dust cakes onto the blades. This reduces airflow and shortens motor life, and the homeowner notices weak air at the far end of the house first.
- The bait-and-switch per-vent price. Some companies quote a low per-vent price, then count all the vents in a long attic run once they’re in the attic. East Palo Alto’s ranches have a lot of register openings for their square footage, and the total balloons fast. We quote one flat price per system, in writing, before we begin.
- Return-side debris that never gets touched. In mid-century homes, the return ducts often route through wall cavities, and they accumulate lint and dust where nobody looks. Without a camera inspection before and after, that debris stays put. We document everything with photos of your actual ducts.
Pricing for Air Duct Cleaning in East Palo Alto, CA
Most standard air duct cleanings in East Palo Alto run $425 – $850 for a single-family home and $650 – $2,800 for commercial spaces, depending on square footage, number of systems, and how much buildup has accumulated. The biggest variable is whether prior cleanings actually happened or whether a previous company just vacuumed the registers. If you’ve never cleaned the system in a 1960s ranch, expect the first cleaning to take longer. If it’s been maintained, it’ll go faster and cost less. You’ll get a written price before any work begins, and that price does not change once the technician is inside. Call (737) 727-2314 for a free estimate on your East Palo Alto property.
One more thing: we never charge per vent. Per-vent pricing is how the bait-and-switch happens. One flat price per system, agreed in writing before we start. That’s how Omar Haddad runs every job, and it’s why our 365-Day Done Right Promise means something real in East Palo Alto.

FAQs About Air Duct Cleaning in East Palo Alto
Every 5 to 7 years for most East Palo Alto homes, and closer to every 3 to 4 years if you live between Highway 101 and the Baylands, where fine dust accumulates faster. Homes with pets, recent renovations, or occupants with allergies will benefit from more frequent cleaning. If you’ve never had it done in a 1960s ranch home, schedule it now and then reassess after two or three years. Call (737) 727-2314 and we’ll help you determine whether it’s actually due or whether you can wait.
One flat price per system, written down before any work starts. We never quote per vent, because East Palo Alto’s ranch homes have long attic runs with many register openings, and per-vent pricing is where the invoice quietly doubles. The price you agree to is the price you pay. Call (737) 727-2314 for a written quote.
We start with a camera inspection of the supply and return ducts to see exactly what’s built up and where. Then we set up negative pressure with Nikro HEPA filtration to capture everything we loosen. We run Rotobrush agitation tools through each duct run, clean the blower motor if it’s accessible, and finish by replacing the register grilles and showing you before-and-after photos of your own ducts. Most ranch homes take 4 to 7 hours. Call (737) 727-2314 for an exact timeline on your property.
East Palo Alto sits directly between a major freeway and the salt marshes, and the prevailing winds push fine silica dust and pollen across the city during dry months. That dust is smaller than typical household dust and passes through most standard filters. Then it settles in the return plenums and blower assemblies. We see it on almost every job here, and it’s a big part of why camera inspection and HEPA extraction matter more in East Palo Alto than in cities with more tree cover. Call (737) 727-2314 to schedule an inspection.
Yes, we regularly bundle a residential cleaning with a small commercial cleaning on the same day, especially for East Palo Alto property owners who live near their shop or own a building with an attached unit. You’ll get a separate written price for each system, and both are covered by the 365-Day Done Right Promise. Call (737) 727-2314 to set up a combined quote.
