Fast, Reliable HVAC Cleaning Across Pomona
HVAC cleaning in Pomona typically costs $280–$580 for a complete system service, and most jobs are completed in a single visit. Richard Anderson personally leads every job as lead technician — no subcontractor crews, no handoffs.
We’ve been driving out to Pomona from Bell for 14 years, and we know the difference between a home up near Cal Poly and one down in the 91766 tract neighborhoods off Holt Avenue. The valley geography here changes everything about how your system gets dirty. If you’re in Pomona and your vents are pushing dust, your energy bills are climbing, or your system just smells stale when it kicks on, call us at (833) 958-5022. We’ll give you a straight answer about whether cleaning will solve it or if your ductwork needs more.
Our HVAC Cleaning team handles the full scope: evaporator coils, blowers, condensers, air handlers, and heat exchangers. We bring Rotobrush and Nikro professional systems — the same equipment commercial restoration contractors use, not a shop vac with a brush attachment.
Why Landmark Air Duct Cleaning Service California Is Pomona’s Preferred HVAC Cleaning Company
Richard Anderson shows up. Not a crew you’ve never met. That’s the difference between an owner-operator and a franchise dispatch board.
Our 4.9-star average across 364+ verified reviews didn’t come from cherry-picking the good ones. It came from 14 years of doing one thing: cleaning air ducts and HVAC systems. We don’t do windows. We don’t do carpets. We clean ducts, repair ductwork, and improve indoor air quality — and we’ve done it in Pomona long enough to know that a 1962 ranch near Towne Avenue presents different problems than a 1980s split-level up by Foothill Boulevard.
From Bell, we’re typically at your Pomona door within 45–60 minutes during scheduled windows. We serve all Pomona ZIP codes: 91767, 91768, 91769, and 91797. Richard handles the diagnostic himself, runs the equipment, and signs off on every job.
Our HVAC Cleaning Services in Pomona
Evaporator Coil Cleaning
Pomona’s particulate load is brutal on evaporator coils. The city’s bowl geography traps ozone and freight corridor dust, and when Santa Ana winds hit each fall, that load gets supplemented with Mojave Desert silica. A dirty coil in Pomona isn’t just inefficient — it’s a mold incubator in summer humidity. We clean coils in-place with foaming agents and low-pressure rinse, then verify airflow recovery with a digital manometer. Typical evaporator coil cleaning in Pomona runs $180–$320.
Blower Cleaning
The blower wheel is where Pomona’s dust accumulates most visibly. We’ve pulled blower assemblies from 91767 homes that were so caked the motor was drawing 30% more amperage than spec. That shows up on your SCE bill. We remove the housing, clean the wheel and squirrel cage with compressed air and solvent, balance the assembly, and reinstall. Blower cleaning in Pomona typically costs $150–$260.
Condenser Cleaning
Outdoor condensers in Pomona fight a two-front war: the standard cottonwood and pollen load, plus the fine desert dust that settles during Santa Ana events. We use foaming cleaner and low-pressure wash — never high-pressure, which fin-folds the aluminum. For homes near the 71 freeway or down in the 91766 flats, we often find condensers needing deeper fin combing. Condenser cleaning in Pomona runs $120–$220.
Air Handler Cleaning
This is where Pomona’s older housing stock hurts most. The air handler cabinet — especially in post-WWII homes with original sheet-metal plenums — collects debris at the return drop and around the filter rack. Worse, corroded joints upstream let attic air bypass the filter entirely, so the handler gets coated with raw particulate. We clean the full cabinet interior, treat for microbial growth, and inspect every joint in the attached ductwork. Air handler cleaning in Pomona typically runs $200–$380, with sealing work additional if we find bypass gaps.

Trusted Brands We Service in Pomona
We work on systems running Honeywell, Aprilaire, and Guardsman components regularly — and we stock common replacement parts for Pomona customers so you’re not waiting on a warehouse shipment. Our Rotobrush and Nikro equipment handles the cleaning side; when we find a failed component during service, we can usually source Honeywell media filters, Aprilaire filter cabinets, or Guardsman UV treatment bulbs without a return trip. Fast turnaround matters when your system’s already apart.
Common HVAC Cleaning Problems We See in Pomona Homes
- Disintegrated fiberglass wrap on attic flex duct creates raw-air bypass at every joint, drawing Pomona’s Santa Ana desert dust directly into the supply side. The wrap turns to powder after years of 140–150°F attic heat, and homeowners never know until we show them the photos.
- Original galvanized sheet-metal crimp joints corrode through after decades of extreme attic heat, creating hidden particulate entry points that standard cleaning misses. We find these constantly in 91766 and 91767 — joints that look intact from the outside but have rusted through at the crimp.
- Long-term rental properties with 20+ years of deferred duct maintenance often have disconnected or partially collapsed flex segments that require replacement, not just cleaning. The tenant turnover cycle means nobody owns the problem until a new owner calls us.
- Filter bypass from ill-fitting or missing filter racks in original air handlers lets Pomona’s heavy particulate load coat the evaporator coil directly, accelerating fouling and reducing heat transfer efficiency by 20% or more.

FAQs — HVAC Cleaning in Pomona
Because galvanized steel was built to last, and in Pomona’s post-WWII building boom it was cheap and fast to install — but “last” doesn’t mean “stay sealed.” After 60–70 years of 140–150°F attic cycling, the crimp joints corrode and the fiberglass wrap disintegrates. The metal itself is often sound; it’s the connections and insulation that fail. We can clean the intact runs and seal the failures without full replacement in most cases. Call (833) 958-5022 for a free inspection — Richard will show you exactly what’s salvageable.
Santa Ana winds funnel Mojave Desert dust westward through the Pomona Valley each fall and winter, loading your attic and crawl space with fine silica particulate that standard filters don’t catch. If your ductwork has any bypass gaps — and in Pomona’s older homes, it usually does — that dust enters your supply air directly. We see the heaviest contamination in January–March, right after Santa Ana season. Cleaning in fall, before the winds hit, prevents the buildup. Call (833) 958-5022 to schedule pre-season service.
Expect deferred maintenance that goes beyond cleaning. In Pomona’s long-term rental stock, we routinely find flex duct segments that have partially collapsed, original fiberglass wrap that’s turned to powder, and filter racks clogged with years of accumulated debris. We’ll give you a straight assessment: what’s cleanable, what needs repair or replacement, and what the priorities are. Our estimates are free, and we work with property managers regularly. Call (833) 958-5022 — we’ll coordinate with tenants directly if needed.
Yes, in most Pomona homes with original sheet-metal ductwork, we can seal corroded crimp joints and disconnected segments with mastic and mesh reinforcement — a permanent repair that doesn’t require tearing out intact runs. On a 1957 ranch home near Holt Avenue and Towne Avenue in 91766, our techs found that the original sheet-metal supply trunk had a 6-inch gap at the main takeoff where the crimp joint had corroded through, pulling unfiltered attic air loaded with I-10 freight corridor particulates directly into the bedrooms. We performed a Rotobrush cleaning of the intact runs, then sealed the failed joint with mastic and mesh before installing a new Aprilaire filter cabinet to intercept the dust that had been bypassing the system for years. Not every gap is sealable — we’ll tell you if replacement is the honest answer. Call (833) 958-5022 for an inspection.
Cleaning the duct interior is still worth doing — but without replacing or re-wrapping the insulation, you’re leaving the thermal and particulate bypass problem unsolved. In Pomona’s climate, bare flex duct in a 150°F attic loses cooling efficiency immediately and draws attic air at every joint. We typically recommend cleaning plus re-wrapping with new insulation jacket, or upgrading to insulated flex where the original has stiffened and cracked. Richard will show you photos and give you both options with real numbers. Call (833) 958-5022 for a free estimate.
