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 Mountain View
HVAC cleaning in Mountain View typically runs $325 – $575 for a single system in a standard ranch or Eichler-style home, and the job usually takes two to four hours. That price covers the full system: supply ducts, return ducts, air handler, blower, evaporator coil, and treatment. If you’re in Monta Loma, Cuesta Park, or off Shoreline and your system hasn’t been touched in years, call us at (737) 727-2314 and we’ll give you a written quote before any work starts.
We know Mountain View’s housing stock better than most. The difference between a 1958 ranch on Devonshire Avenue and a 2015 townhouse in North Whisman isn’t just square footage; it’s the ductwork, the return sizing, and the amount of construction dust and pollen that’s settled inside. Our crews live and work in this area, and we schedule around your day, not the other way around.
Every visit starts with a camera inspection, not a sales pitch. You’ll see your own ducts on screen before we recommend anything. That’s the standard here, and it’s why our HVAC Cleaning process always begins with what the system actually needs rather than what we’d like to sell.

Omar Haddad runs our Mountain View operation with a simple rule: the price you’re quoted is the price you pay.

Omar started with the Relay Home Co. family back in 2005, and he’s built the Mountain View crews around technicians who show up in uniform, background-checked, and carrying the equipment we actually use: Rotobrush rotary brush systems, Nikro HEPA vacuums, and Abatement Technologies containment units.
Mountain View homeowners call us because the booking experience matches how they live.

Furnace Cleaning in Mountain View
Furnace Cleaning in Mountain View means opening the cabinet, pulling the blower assembly, cleaning the blower wheel and motor housing, brushing the heat exchanger, and extracting debris with negative pressure rather than blowing it around your home. A typical furnace cleaning here runs $175 – $350 as part of a full HVAC cleaning job, depending on furnace type and how many years of buildup we’re dealing with. Mountain View’s older ranches in Monta Loma and Cuesta Park often have original mid-century furnaces with blower wheels caked in decades of fine dust, and those take longer to clean properly.
Blower Cleaning and Heat Exchanger Care
The blower wheel is where most of the resistance builds up. A dirty blower moves less air, which makes the furnace run longer and work harder. On 1950s and 1960s furnaces in Mountain View, we regularly see blower wheels so coated that airflow drops 30% or more. We remove the blower, clean each blade, and verify the motor is pulling the right amperage before we close it up.
The heat exchanger gets brushed and inspected during every furnace cleaning in Mountain View. Surface rust and dust are normal; cracks are the thing we’re checking for. If there’s any doubt about heat exchanger integrity, we’ll tell you on the spot and recommend a licensed HVAC technician before we proceed further. Safety comes first.
Return Duct and Air Handler Cleaning
Mountain View’s older homes often have undersized return ducts, which means they pull harder and collect more dust per square inch than modern systems. We spend extra time on the return trunk and the air handler because that’s where the real work hides. A clean return and a clean blower do more for your airflow than thirty minutes of register vacuuming ever will.
AC Vent Cleaning in Mountain View
AC Vent Cleaning in Mountain View involves removing each register, brushing the boot and the first few feet of duct, and cleaning the supply runs back to the main trunk. For a standard single-system home in Mountain View, expect $125 – $275 when done as part of a full HVAC cleaning. The price stays flat; we quote per system, so you won’t see the number creep up when we count your registers.
Mountain View’s homes split hard by era. The Eichler-style and early ranch homes north of El Camino Real and in Monta Loma were built with hard-ducted returns that run through crawlspaces, and those systems pick up dust and moisture differently than the sealed mechanical closets in newer North Whisman builds. A 1957 home with six registers might need more time on the return trunk than a 2018 home with twelve registers and tight ductwork. Two houses four blocks apart can need completely different scopes of work.
Supply Run Cleaning and Register Sealing
Supply runs in Mountain View’s older homes often have gaps at the register boots, which lets dust from the crawlspace get pulled into the living space. We seal those gaps during AC vent cleaning and show you the difference in the after photos. You shouldn’t pay for a cleaning that leaves the same leaks that caused the dust in the first place.
Evaporator Coil and Condenser Cleaning
In Mountain View’s mild climate, the AC coil still gets a film of dust and pet hair every season, which cuts cooling efficiency. We clean the evaporator coil with a coil-safe treatment when we’re already in the system, and we’ll clean the condenser unit outside if it’s part of your package. A clean coil makes a real difference in how quickly your home cools down in July and August, when Mountain View can push past 85°F for weeks.
Trusted Brands We Service in Mountain View
We service every major HVAC brand found in Mountain View homes: Carrier, Trane, Lennox, Rheem, Goodman, Bryant, and York, plus the mini-split systems we see everywhere in newer Mountain View additions. We stock common filters and coils for these systems locally, so most jobs don’t wait on parts. For filtration, we carry Honeywell, Aprilaire, and Guardsman products, and our crews run Rotobrush brush systems and Nikro HEPA vacuums. If you’ve got an older system in a Cuesta Park home or a newer inverter unit in a North Whisman condo, we’ve worked on it before.
Common HVAC Cleaning Problems We See in Mountain View Homes
- Crawlspace duct leaks in Monta Loma and Cuesta Park. The 1950s hard-ducted systems in these neighborhoods run through crawlspaces, and the flexible connectors at the trunk degrade over time. Dust, moisture, and sometimes rodent activity get pulled straight into the HVAC system. We camera-inspect those runs before cleaning so we know what we’re dealing with.
- Oversized filters masking undersized returns in Eichler-style homes. Homeowners install high-MERV filters to catch dust, but the original return ducts can’t handle the added resistance. The blower strains, airflow drops, and the filter frame cracks. We see this constantly in Mountain View’s Eichler tracts. We’ll recommend the right filter for your system, not the thickest one on the shelf.
- Construction dust in newer North Whisman and downtown Mountain View builds. Renovations and teardown-rebuilds are constant in Mountain View, and that fine drywall dust works its way into neighboring systems through shared walls and open windows. A new coat of paint doesn’t remove what’s settled inside the ducts. Newer homes need cleaning too, just for a different reason than the old ranches.
- Unbalanced air handlers pulling lint from cracked filter frames. Our crew recently worked a 1958 ranch on Devonshire Avenue in Monta Loma where the homeowner was convinced her HVAC needed an all-day deep clean. A camera inspection down the supply and return ducts showed light surface dust but a badly unbalanced air handler pulling lint from a cracked filter frame. We set up negative pressure and HEPA filtration, performed source removal on the return trunk, sealed the filter frame, and showed her the before-and-after photographs. She paid one flat price for the system, not per register, and we told her the supply runs genuinely did not need touching for another few years.

FAQs About HVAC Cleaning in Mountain View
Every three to five years is honest for most Mountain View homes, depending on pets, construction nearby, and whether the ducts draw from a crawlspace. Older ranches in Monta Loma and Cuesta Park with crawlspace ducting tend to collect dust faster than newer sealed systems. If you’ve had a renovation, or if your filters are coming out gray and fuzzy every month, you’re probably due. Call (737) 727-2314 and Omar can talk through your situation in two minutes, no obligation.
Per system, always. A flat price covering the full HVAC system, quoted in writing before we start, and it does not change. We don’t do per-vent pricing because on Mountain View’s small 1950s ranches with six to ten registers, that model charges you for the cheap part and hides the real work in the return and air handler. One price, one system, no surprises at the door.
Partly, and it depends where the dust is entering. If the dust is coming from a leaking return duct in the crawlspace or a cracked filter frame, a proper cleaning with sealing will cut it down significantly. If the dust is from old carpets, open windows on Shoreline Boulevard, or a shedding pet, duct cleaning helps with the airborne circulation but won’t eliminate the source. We’ll tell you honestly what to expect after the camera inspection.
We start with a camera inspection down your supply and return ducts so you and we see exactly what’s inside. Then we set up negative-pressure containment using a Nikro HEPA vacuum, brush the ducts with a Rotobrush system, clean the blower, air handler, and coils, and seal any gaps we find. You get before-and-after photographs of your own ducts, not stock images. The whole visit usually takes two to four hours for a single system.
We don’t promise same-day or next-day HVAC cleaning. Source removal done right takes time, and rushing a two-system Eichler or a crawlspace-ducted ranch without camera inspection is exactly how blowers stay caked and homeowners see no airflow change. We schedule based on what your system actually needs and we’ll give you a live trackable arrival window so you know exactly when we’re coming. To book, call (737) 727-2314; a live person answers around the clock.
