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 HVAC Cleaning Across San Ramon
HVAC cleaning in San Ramon typically runs between $450 and $1,400 for a full system, depending on square footage and the number of zones. Most jobs on Dougherty Valley and Gale Ranch homes take one full day. If you’re calling from San Ramon, we answer live at (806) 606-6902 and will quote a written price before any work starts. No exceptions.
We know San Ramon’s housing stock better than most companies that pass through on I-680. The master-planned communities here, especially Dougherty Valley and Gale Ranch, were built fast between 2000 and 2015. The duct systems in those homes share a specific contamination profile that we see on nearly every first visit. We’ll walk you through exactly what that means before a single panel comes off.
Why CleanRun Air Duct Cleaning Is San Ramon’s Preferred HVAC Cleaning Company
San Ramon homeowners don’t want a $79 coupon and a shop vac. They want documentation. That’s how CleanRun has operated since 2013: every job ends with a photographic record of every duct run, before and after. You see what was inside. You see what it looks like when we leave. The photos are yours, included as a standard deliverable under Haven Standard Clause 4.
Our HVAC Cleaning team works throughout San Ramon every week, from the Dougherty Valley neighborhoods east of Dougherty Road to the older sections near San Ramon Valley Boulevard. Led by Tomas Reyes, our crews are background-checked and uniformed. They arrive with professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies. And every job carries the 365-Day Done Right Promise in writing: if it’s not right, we make it right. Not a policy subject to manager approval. A written guarantee.
San Ramon presents a specific challenge that companies based in Oakland or San Jose rarely understand: the sheer size and zoning complexity of homes here. A 4,000-square-foot Gale Ranch home with four zones and long flex-duct runs is a fundamentally different job than a 1,800-square-foot 1960s ranch in Hayward. We quote for the system as it actually exists, not by a per-vent price that balloons by the time the van door closes.
Our HVAC Cleaning Services in San Ramon
Evaporator Coil Cleaning
The evaporator coil sits inside your air handler and is the single most common efficiency killer in San Ramon homes. During a six-month cooling season, the coil in a Dougherty Valley system collects pollen from the Diablo Range foothills, wildfire ash, and whatever your filters miss. A dirty coil adds measurable load to the compressor. In San Ramon, we clean coils using the same negative-pressure extraction methods used on the ductwork itself. Typical coil cleaning here runs $150 to $350 as an add-on to a full system cleaning, or $250 to $500 standalone depending on access.
Air Handler Cleaning
The air handler is the box that houses the blower motor, the evaporator coil, and often the filter rack. In the large 2,500-to-4,500-square-foot tract homes that dominate San Ramon, air handlers are typically installed in attics or dedicated closets. Construction dust from the buildout years settles inside these units and recirculates through every supply register. Every air handler cleaning includes the blower wheel, the housing interior, and the condensate pan. We photograph the inside of the air handler before we start and after we finish. Air handler cleaning in San Ramon runs $200 to $450 when bundled with full duct cleaning.
Condenser Cleaning
Your outdoor condenser in San Ramon faces a year-round assault: summer heat, Diablo wind dust, grass clippings from HOA-maintained lawns, and wildfire ash in the fall. We remove the fan guard, clean the coil fins with professional-grade coil cleaner compatible with manufacturer specs, flush the coil, and clear the condensate line. In San Ramon, condenser cleaning is priced as a flat $175 to $325 depending on unit size and condition. If the fins are severely impacted or the unit sits against a fence line that restricts airflow, we’ll show you photos of the problem before quoting additional work.
Blower Cleaning
A clogged blower wheel doesn’t just reduce airflow. It throws the whole multi-zone system out of balance, which is why some rooms in San Ramon homes run five degrees warmer than others. Blower cleaning involves removing the wheel, degreasing the blades, and rebalancing. San Ramon blower cleaning runs $200 to $400 as part of a full system service. If your system is older and the blower motor bearings are worn, we’ll note it in the written record and leave the replacement decision with you. No pressure. Just documentation.

Common HVAC Cleaning Problems We See in San Ramon Homes
- Construction dust in long Dougherty Valley runs. Homes built between 2000 and 2015 routinely show a 2-to-3-inch layer of drywall and insulation dust in the main trunk line. Filters look fine because this dust predates the current filter. It’s been sitting there since the drywall crew left.
- Gray staining around registers from leaky flex duct. In Gale Ranch homes specifically, we find original flex duct that was never pressure-tested. Attic insulation fibers get pulled into supply air and deposit as gray staining around every register. This is not dirt from inside the house. It’s attic infiltration.
- Wildfire smoke re-coating cleaned ducts within weeks. San Ramon’s inland valley position pulls Northern California wildfire smoke into the basin. Homes running AC during fire season pull that particulate load directly through the return plenum. Low-MERV filters can’t stop it, and ducts that were cleaned in March look dirty again by September.
- HOA scheduling conflicts in planned communities. Dougherty Valley and Gale Ranch HOAs often restrict parking, require advance notice for contractor vehicles, and designate specific access hours. We handle that coordination. If your HOA needs a certificate of insurance before scheduling, we’ll provide it same day.

FAQs - HVAC Cleaning in San Ramon
Dougherty Valley homes were built between 2000 and 2015 using long flex-duct runs and multi-zone systems that were rarely pressure-tested for leaks. Walnut Creek’s older housing stock, by contrast, tends toward metal duct and shorter runs. The Dougherty Valley systems require substantially more labor to clean thoroughly and almost always reveal construction-era contamination that older homes simply don’t have. If you’re getting a quote, make sure the company knows which kind of house you actually have. Call (806) 606-6902 and we’ll ask the right questions.
Gray staining around supply registers in Gale Ranch homes is a sign that the original flex duct was never pressure-tested at the seams. Attic insulation fibers get pulled through those seams and into the supply air stream, depositing as a fine gray film around every register. It is not household dust and it is not mold. It is attic contamination. The fix is duct sealing at the seams plus full source removal of the accumulated material inside the ducts.
Yes. San Ramon’s inland valley position funnels wildfire smoke and Diablo wind-driven particulates into the basin, and running air conditioning during fire season pulls that load directly through the return plenum. Coastal cities like Hayward get significantly less particulate deposition because the marine layer scrubs some of it out. San Ramon homes running modern AC during a fire event can re-contaminate cleaned ducts within a single season if the filtration isn’t upgraded at the same time.
Condo and apartment HVAC cleaning in San Ramon requires coordinating with building management and sometimes the HOA board, because shared plenums or stacked duct runs mean your unit’s system may connect to neighbors’. We typically need access confirmation and sometimes a certificate of insurance filed with the property management office before scheduling. We handle that paperwork on our end. The cleaning itself is usually faster than single-family work because the duct runs are shorter.
In stacked condo buildings common throughout San Ramon, dryer vents run through shared chases and vertical stacks. A clogged vent in one unit can create back-pressure that affects units above or below. That makes dryer vent cleaning a shared-infrastructure issue, not just a personal maintenance item. We include dryer vent inspection and cleaning as an option on every multi-unit HVAC job, with pricing based on vent length and access.
