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 San Bernardino
HVAC cleaning in San Bernardino means dealing with a specific kind of contamination: fine Mojave desert sand that blows through Cajon Pass, settles into your ductwork, and recirculates through your home every time the system kicks on. Most San Bernardino homes we inspect have enough grit in the supply and return runs to fill a coffee can, and the evaporator coils are usually worse. We clean the entire system – coils, blower, air handler, plenum, and every duct run – and we photograph the inside before and after so you can see exactly what was removed. Call (806) 606-6902 for a written price before any work starts.
Why CleanRun Air Duct Cleaning Is San Bernardino’s Preferred HVAC Cleaning Company
Since our first job in 2013, we have held one rule that matters more than any marketing promise: the inside of every duct run gets photographed before and after cleaning. San Bernardino homeowners see the tan grit, the collapsed flex duct, the separated sheet-metal seams – not a vague assurance that the system is “cleaner.” Our crews know the older Westside housing stock, the post-war tract homes along Highland Avenue, and the Muscoy area properties where wind-driven sand finds every gap in aging trunk lines.
Every technician who arrives in San Bernardino is background-checked, uniformed, and identified by name before they step out of the truck. You get a written price before a single panel comes off. And because we work under Haven Standard Clause 3 – Verified Crews – you know who is in your home and what they are doing there. That matters in a city where too many companies send a subcontractor with a shop vac and a coupon.
Our HVAC Cleaning Services in San Bernardino

Evaporator Coil Cleaning
In San Bernardino, evaporator coils take a beating. The South Coast Air Basin ranks worst in the nation for PM2.5 and ozone, which means the air moving across your coil carries fine particulates that bake onto the fins. A coated coil loses heat transfer efficiency, so your system runs longer and your summer bill climbs. We remove the coil, clean it with professional-grade equipment, and show you the before-and-after photos. A typical evaporator coil cleaning in San Bernardino runs $180-$320 depending on access and buildup.

Air Handler Cleaning
The air handler is where desert grit accumulates fastest. After a Santa Ana event, we frequently find the blower housing caked with tan sand that made it past the filter. That grit scores bearings, unbalances the blower wheel, and shortens motor life. Air handler cleaning in San Bernardino typically costs $220-$380, and it includes removing the blower assembly, cleaning the housing, and clearing debris from the condensate pan and drain line.

Blower Cleaning
A blower motor covered in fine Mojave dust is working harder than it should. We see it constantly in San Bernardino homes – the fan blades coated, the housing full, the airflow dropping even when the filter looks fine. Cleaning the blower restores static pressure and airflow, which means your system delivers the air volume it was designed for. Blower cleaning as a standalone service runs $150-$280. As part of a full HVAC Cleaning, it is included at no extra charge.

Condenser Cleaning
Your outdoor condenser sits in the path of everything the Cajon Pass wind carries. Cottonwood fluff from the Santa Ana River wash, dust from the 215 corridor, sand from the high desert. A clogged condenser coil drives head pressure up and cooling capacity down. We clean the fins, straighten what can be salvaged, and verify the system is moving heat properly. Condenser cleaning in San Bernardino generally runs $140-$260.

Common HVAC Cleaning Problems We See in San Bernardino Homes

- Tan Mojave sand in the plenum and return runs. After a wind event through Cajon Pass, the plenum often holds a gritty deposit that looks like beach sand. That signature means unfiltered outside air is entering through separated duct seams, and cleaning alone will not fix it – the seam needs to be sealed too.
- Collapsed or disconnected flex duct in post-WWII tract homes. Many San Bernardino houses built from the late 1940s through the 1970s still have original sheet-metal trunks, with flex duct added during remodels now sagging, kinked, or fully separated. Air you paid to condition never reaches the register.
- Evaporator coils layered with combustion ash. Post-wildfire events from the San Bernardino National Forest add fine carbon particles to the desert dust already in the air. That ash film on the coil reduces efficiency and can hold moisture, which becomes a microbial problem the next time humidity rises.
- Blower motors caked with fine particulates. Even homes with MERV 11 filters show significant buildup because wind-driven sand bypasses standard filtration during high-velocity gust events. The blower wheel gets coated, unbalanced, and noisy – and airflow drops throughout the entire system.
Pricing for HVAC Cleaning in San Bernardino, CA
We publish our price ranges because Haven Standard Clause 1 requires a written price before any work starts – not a “call for a quote” runaround. In San Bernardino, a full HVAC cleaning covering the evaporator coil, blower, air handler, and all duct runs typically runs $650-$1,200 depending on system size, accessibility, and how much buildup is present. The final written price is agreed before we touch anything, and it does not change when we find more contamination than expected. That is the whole point of the written estimate. Call (806) 606-6902 and we will put the number in writing.
What affects the price in San Bernardino specifically: the age of the ductwork (post-war sheet metal needs more sealing work than newer flex), how many returns the home has, and whether desert grit has reached the blower assembly. We also offer a free second opinion on any written estimate you have from another company – bring it to us and we will put our number next to it.

FAQs - HVAC Cleaning in San Bernardino

Your home is pulling in desert sand through gaps in the duct system itself. San Bernardino sits at the mouth of Cajon Pass, and during Santa Ana wind events, gusts reaching 60-80 mph force fine Mojave sand past even tight window seals. But the sand you find in the plenum is not coming through the windows – it is entering through separated seams, disconnected flex duct joints, or gaps at the return-air chase. The tan, gritty deposit is the signature of unfiltered outside air entering the duct run, and the only real fix is cleaning plus sealing the leak. Call (806) 606-6902 and we will send a camera down the run to find exactly where the sand is coming in.
No. Fogging a sanitiser into ductwork without removing the material that feeds microbial growth is a temporary cosmetic treatment. In San Bernardino, the nutrients are desert grit, combustion ash, and organic debris trapped in the duct run. Moisture from a wet winter combines with that material and supports continued growth, and a fog cannot eliminate the food source. Source removal with negative-pressure extraction, followed by mechanical agitation and HEPA filtration, removes the material. Only after the debris is gone does sanitizing make sense. We document the removal with before-and-after photos so you know what was actually removed, not just sprayed.
Homes in San Bernardino’s wind corridor should have a full HVAC cleaning every 2-3 years, not the 5-7 year interval common elsewhere in Southern California. The Mojave sand and South Coast Air Basin particulate load in this specific geography means ducts in Rialto or Riverside accumulate contamination roughly 30-40% slower than homes directly in the wind path. If you are near the 210/215 interchange or in the northern reaches of the city close to the pass, err toward 2 years. We can inspect the plenum with a camera and tell you exactly where your system stands – free inspection with any cleaning.
Your air filter stops particles before they enter the system. The evaporator coil is downstream, and in San Bernardino, fine desert sand and PM2.5 from the air basin get past even MERV 11 filters during high-velocity wind events. That material coats the coil fins, reducing heat transfer and forcing your system to run longer. Changing the filter does nothing for the coil. Coil cleaning removes the baked-on film, restores efficiency, and in our San Bernardino jobs typically drops the system’s temperature differential back to manufacturer spec. We show you the coil before and after so there is no ambiguity about what was there.
Because during a Santa Ana event, wind-driven sand is moving fast enough to bypass even a properly seated MERV 11 filter. The filter catches what it can, but the fine particles slip through and accumulate on the blower wheel and motor housing. We see this pattern constantly in San Bernardino homes – the filter looks dirty enough to be doing its job, but the blower wheel is coated in fine grit that is wearing the bearings and reducing airflow. Cleaning the blower assembly restores airflow and extends motor life. We include blower cleaning in every full HVAC Cleaning job, and we photograph the wheel before and after.
