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 HVAC Cleaning Across East Foothills
HVAC cleaning in East Foothills means pulling the oak pollen, diablo-wind dust, and fog-season matting out of your air handler, blower wheel, and evaporator coil. A standard whole-system cleaning for a typical East Foothills home runs $380 – $650, and the job takes a full day when done properly, not an hour. We’re the local crew that shows up with Rotobrush agitation whips and Nikro HEPA vacuums, hands you a written price before touching a single duct, and leaves you with before-and-after photos of your own system.

Why Cardinal Air Duct Cleaning Is East Foothills’s Preferred HVAC Cleaning Company
East Foothills homeowners call us because they’ve already been through the bait-and-switch routine somewhere else: a $49 coupon that somehow became $600 once the tech was inside the house. That doesn’t happen with us. Omar Haddad runs this operation on one rule – a written price before any work starts, and that price doesn’t move. We’re part of the Relay Home Co. family, founded 2005, which means every booking carries The Relay Visibility Guarantee: a live trackable arrival time, before-and-after photo proof of the work, and a digital invoice you can pay from a link on your phone.
Our techs are background-checked, uniformed, and you’ll know their name before they knock. We run professional equipment – Rotobrush brush systems for duct agitation, Nikro HEPA-rated vacuums for extraction, and Abatement Technologies containment units when the job calls for it. And because we’re an HVAC Cleaning specialist serving East Foothills specifically, we know what these hills do to a system across the seasons.
Every job is backed by the 365-Day Done Right Promise. If the work isn’t right within a full year, we come back and make it right at no charge. That’s not a sales line – it’s a written guarantee on every booking, no exceptions.
AC Cleaning in East Foothills
AC Cleaning in East Foothills is source removal of everything that’s accumulated on your cooling side through the dry season and into the fog months. Around here, that’s a specific cocktail: oak pollen from the Alum Rock corridor, fine dust blown in by the dry diablo winds, and then moisture off the bay that turns all of it into a damp mat on your evaporator coil. A proper AC cleaning for an East Foothills home runs $220 – $400 depending on system size and access.
What the job actually includes
We open the air handler, inspect the coil and blower with a camera, and then remove debris at the source. The supply and return ducts get agitated with Rotobrush whips under negative pressure – meaning loosened debris goes straight into the Nikro HEPA vacuum, not back into your living room. The evaporator coil gets HEPA-vacuumed and treated if the buildup is heavy, and the blower wheel comes clean before the system reassembles.
When East Foothills homeowners call
Most calls start with a symptom: one bedroom staying warmer than the rest of the house, weak airflow from the registers, or a system running longer to hold the same temperature. If you’ve lived in the same home for three or more years and haven’t had the AC side cleaned, the coil is likely carrying a layer of that dry-season pollen and dust. That layer cuts efficiency and forces the compressor to work harder through every heat wave.
Evaporator Coil Cleaning in East Foothills
Evaporator Coil Cleaning in East Foothills targets the specific component where the dry-to-damp cycle does its worst work. The evaporator coil sits inside the air handler, and in this area it absorbs a full season of oak pollen and dry dust before summer fog adds enough moisture to cake everything into a felt-like layer. If you only clean the ducts and skip the coil, you’ve fixed the pipes but left the restriction in place. A standalone coil cleaning in East Foothills runs $180 – $300.
Why the coil matters more here
East Foothills sits at the eastern edge of the Santa Clara Valley, where the return side loads heavily with pollen from spring through fall. Then cool-season fog off the bay carries fine moisture that mats that debris directly onto the blower wheel and evaporator coil. That alternation – dry debris first, damp matting second – means a real HVAC cleaning here requires mechanical agitation and HEPA-filtration recovery, not a quick blow-through. A tech who skips the coil leaves the exact surface where heat transfer happens running at a fraction of its rated efficiency.
What we check while we’re in there
While the coil is exposed, we inspect the drain pan and condensate line for the sludge that forms when that matted debris washes down with coil condensation. A blocked line backs up into the pan and eventually into your ceiling or closet – a common East Foothills summer failure. We also check the filter rack seal, because a gap there lets unfiltered dust pull straight onto the coil the moment the system runs after we leave.
Trusted Brands We Service in East Foothills
Whether your East Foothills home runs a Carrier, Lennox, Trane, Rheem, or Goodman system, our techs are trained on all major residential equipment and we carry common replacement filters, seals, and condensate fittings on the truck. We also install and service Honeywell filtration upgrades and Aprilaire media filters for homeowners who want a better barrier against pollen before it reaches the coil. If your system needs a specific part, we source it fast so you’re not waiting a week with the system down. We know the equipment in these hills – from the 1970s ranch houses off Alum Rock Avenue to newer builds along McKee Road – and we service them all.
Common HVAC Cleaning Problems We See in East Foothills Homes
- Per-vent pricing that quietly excludes the air handler, blower motor, and evaporator coil. Those are the exact components that need source removal first in East Foothills’s dry-to-damp seasonal cycle. A company that quotes per vent is often quoting for the ducts only and leaving the most fouled parts untouched.
- Blow-and-go crews that skip negative pressure and HEPA filtration. Without proper containment, the debris displaced from the supply and return ducts simply resettles on the registers and into the living space. That’s why we run Nikro HEPA vacuums in line with Rotobrush agitation – the debris goes into the machine, not back into your house.
- Same-day service quotes with no camera inspection. A tech who arrives without a camera can’t see a failing flex run or a matted coil until the system’s already open. By then, you’ve committed to what may be the wrong scope. We scope with a camera first so the written price reflects what’s actually in the ducts.
- Dry-season dust pulled back through a low-MERV filter. If no one checked the filter rack seal before cleaning, the system pulls unfiltered air around the filter and redeposits dust on the coil within weeks. We check that seal on every job in East Foothills.

FAQs About HVAC Cleaning in East Foothills
A home in East Foothills needs a full HVAC cleaning every 3 to 5 years if you run a decent filter and change it regularly. If you have pets, live near the open hillsides off Alum Rock Avenue where oak pollen loads heavily, or haven’t changed your filter in a while, plan for every 2 to 3 years. If the system was cleaned in the last year and you’re not seeing airflow problems, you probably don’t need it yet. We’ll tell you if a cleaning is genuinely unnecessary – we’d rather have you call us when it actually matters. Call (737) 727-2314 for an honest read on your system.
We charge one flat price per system, agreed in writing before any work starts. Per-vent pricing is the old trick that quietly excludes the air handler, blower motor, and evaporator coil – the exact components that need source removal first in East Foothills’s dry-to-damp seasonal cycle. Your written quote includes the full system, not a partial pass through the ducts. Call (737) 727-2314 for a system-level quote.
Negative pressure means the cleaning equipment creates suction at the point the debris is loosened, pulling it directly into the vacuum instead of pushing it into your living space. HEPA filtration captures 99.97% of particles down to 0.3 microns – that’s the fine pollen and dust that a basic shop-vac just recirculates. In practice, we connect a Nikro HEPA vacuum to the system, agitate the ducts with Rotobrush whips, and the loosened debris goes straight into the machine. You finish cleaner, not dustier. Call (737) 727-2314 and we’ll show you what your system looks like on the camera.
AC Cleaning covers the entire cooling side – ducts, air handler, blower wheel, and coil. Evaporator Coil Cleaning targets just the coil itself, which is the component where heat transfer happens and where East Foothills’s dry-to-damp seasonal cycle does the worst buildup. If your ducts were cleaned recently but airflow is still weak, the coil is likely the culprit, and a standalone coil cleaning may be all you need. We’ll scope it with a camera and tell you which service fits. Call (737) 727-2314 for a straight answer.
We can often schedule within a few days, and occasionally same-day when the schedule allows. We don’t promise same-day service as a marketing line because a proper HVAC cleaning is a scheduled job, not an emergency call, and cutting corners to hit a same-day promise is exactly how East Foothills homes end up with half-done work. We’d rather book you for the day we can do it fully – with camera inspection, Rotobrush agitation, HEPA extraction, and before-and-after photos of your own ducts. Call (737) 727-2314 and we’ll get you the next available slot.
