Fast, Reliable HVAC Cleaning Across Commerce City
HVAC cleaning in Commerce City, CO typically costs between $280 and $650 for a full system service, with most jobs completed in a single visit by our HVAC Cleaning team. We’re familiar with the specific challenges Commerce City homeowners face, from the legacy ranch homes near the historic Derby corridor to the newer builds in Reunion, and we answer calls 24 hours a day at (844) 685-6342. If you’re noticing weak airflow, uneven temperatures, or dust that keeps returning no matter how often you clean, the problem is likely inside your HVAC components, not your furniture.
Commerce City sits on the high plains northeast of Denver at roughly 5,200 feet, where strong westerly and northwesterly winds push Front Range alkaline dust straight into residential intake vents. What makes this different from Thornton or Westminster is the Suncor Energy refinery operating within city limits, one of the largest oil refineries in the Rocky Mountain region. That facility introduces petrochemical particulates and sulfur compounds into the ambient air that neighboring communities simply don’t experience at the same concentration. Your HVAC system doesn’t filter what it can’t reach, and when coils, blowers, and air handlers become coated, efficiency drops and indoor air quality suffers. We’ve been serving this corridor for over 42 years, and we know the difference between standard dust accumulation and the crusted, greasy buildup that refinery-corridor homes develop.

Our HVAC Cleaning Services in Commerce City
Evaporator Coil Cleaning
The evaporator coil in your air handler is where cooling actually happens, and in Commerce City, it’s also where refinery particulates and alkaline dust form a stubborn crust that standard coil cleaner won’t touch. We cleaned an evaporator coil in a 1963 ranch on East 84th Avenue in the Derby neighborhood. The return duct was undersized and the sheet-metal riser had decades of drywall dust and fossilized lint, causing a 12°F temperature drop across the coil. After sealing the duct joints with mastic and cleaning the coil with a Rotobrush, airflow normalized. In Reunion homes, we see the same coil-fouling problem caused by builder debris that was never fully evacuated during construction. Our two-step treatment, degreasing agent followed by foaming cleaner, breaks down what Commerce City’s unique air deposits.

Air Handler Cleaning
The air handler is the heart of your forced-air system, housing the blower, coil, and often the filter rack. In older Commerce City homes near Derby, air handlers frequently sit in cramped basement corners with original sheet-metal plenums that have never been properly sealed. Cleaning the air handler without addressing those leaks is half a job, we redistribute contaminants through the same gaps they entered through. We inspect and seal before we clean, using mastic on metal joints and proper supports for flex connections. Newer Reunion homes have more accessible air handlers, but they’re often choked with construction dust that the builder’s rough clean missed. Either way, we camera-verify before and after.

Heat Exchanger Cleaning
Gas-fired furnaces in Commerce City’s older housing stock, particularly the 1940s through 1970s ranches south of 72nd Avenue, often have heat exchangers that have never been inspected, let alone cleaned. A cracked or fouled heat exchanger is a genuine safety hazard, carbon monoxide can escape into conditioned air. We do not provide DIY guidance on heat exchanger inspection because the risks are real and the signs are not always visible to untrained eyes. Our technicians examine heat exchangers with borescope cameras as part of our HVAC cleaning protocol, and we document findings for your records. If we find cracks or deterioration, we explain exactly what we found and why replacement is the only safe option. No scare tactics, just facts you can verify.

Blower Cleaning
The blower wheel moves all the air your home breathes, and when it’s coated with dust and grease, it works harder, runs hotter, and delivers less. In Commerce City, blower contamination happens faster than in more sheltered parts of the metro because of the wind exposure and the additional particulate load from the Suncor corridor. We remove blower assemblies for cleaning when accessible, or clean in place with specialized tools when the housing design requires it. After cleaning, we check amp draw and balance to confirm the motor isn’t straining against residual buildup.

Condenser Cleaning
Your outdoor condenser coil rejects heat to the outside air, which in Commerce City means it’s also catching cottonwood fluff, gravel dust from nearby construction, and the same alkaline particulates that coat everything else. A dirty condenser raises head pressure, increases energy consumption, and shortens compressor life. We clean condenser fins with low-pressure, high-volume water and specialized foaming agents that won’t damage delicate aluminum. We also clear the concrete pad and surrounding area of debris that will blow right back in.

Trusted Brands We Service in Commerce City
We clean and service HVAC equipment from every major manufacturer, and we maintain professional-grade cleaning equipment from Nikro, Abatement Technologies, and Honeywell, the same brands serious HVAC contractors specify for their own work. For Commerce City customers, this means we don’t need to order specialty tools or wait for parts shipments from Denver. Our trucks carry the agitation equipment, compressed air systems, and coil treatment chemicals needed for both legacy sheet-metal systems in Derby and modern flex-duct installations in Reunion. Most jobs are completed in a single visit because we arrive prepared for what this specific market requires.
Common HVAC Cleaning Problems We See in Commerce City Homes
- Builder debris in Reunion flex-duct systems. In northern Reunion subdivision (80037), builder debris and drywall dust are often packed into flex-duct systems. Standard vacuum-only cleaning can miss particulates lodged in corrugations, requiring compressed air agitation to fully dislodge and remove them.
- Leaking original ductwork in Derby-area homes. Older Derby-area homes (80022) with original sheet-metal returns nearly always need duct-seal repair before cleaning. Attempting cleaning on leaking ducts redistributes contaminants instead of removing them, you’re just moving the problem around.
- Refinery-corrosion crust on evaporator coils. Refinery-corridor particulates mixed with alkaline dust form a crust on evaporator coils that resists standard coil cleaner, requiring a two-step treatment with a degreasing agent followed by a foaming cleaner. This is a Commerce City-specific problem we don’t encounter in Westminster or Northglenn.
- Undersized returns choking airflow. The 1950s through 1970s ranch homes concentrated in southern Commerce City were built with returns sized for smaller equipment and less insulation. Even a clean system can’t perform when the return path is too restrictive, we identify this during our pre-cleaning inspection and advise on correction options.

FAQs - HVAC Cleaning in Commerce City
Builder debris and drywall dust were never fully removed from your flex-duct system during construction, and the ongoing particulate load from the Suncor refinery less than five miles south accelerates contamination beyond what the standard “clean every 3-5 years” rule assumes. We see this exact pattern in Reunion homes under ten years old, compressed air agitation is usually required to dislodge particulates from flex-duct corrugations that vacuum-only cleaning misses. Call (844) 685-6342 for a camera inspection and exact quote, estimates are free.
Original sheet-metal ductwork is often more durable than modern flex-duct and can be restored to good performance with proper sealing and cleaning, provided the metal itself isn’t rusted through or structurally compromised. We inspect with cameras first, then seal joints with mastic before cleaning so contaminants are extracted, not redistributed. Replacement is only necessary when we find deterioration we can’t repair. Call (844) 685-6342 and we’ll show you exactly what you have.
Commerce City is the only Denver-metro community where residential HVAC systems routinely intake ambient air carrying petrochemical particulates, sulfur compounds, and industrial emissions on top of standard Front Range dust, creating a crusted, greasy buildup on coils and blowers that standard cleaning chemicals won’t dissolve. Denver and Aurora homes don’t experience this same particulate signature, which is why we use a two-step degreasing and foaming treatment specifically for refinery-corridor properties. Call (844) 685-6342 to discuss whether your home’s location warrants this protocol.
We use professional-grade equipment from Nikro for vacuum and agitation systems, Abatement Technologies for HEPA filtration and containment, and Honeywell for air quality verification tools, the same brands specified by serious HVAC contractors. Our Rotobrush systems handle both the tight turns of older Derby sheet-metal and the corrugated interiors of Reunion flex-duct. Call (844) 685-6342 for specifics on what your system requires.
Yes, we offer a two-step coil treatment specifically formulated for the degreasing and foaming sequence that refinery-corridor particulates require, typically adding $120-$180 to a standard evaporator coil cleaning. This isn’t an upsell, it’s a necessary adaptation for the Suncor-plume area that we don’t recommend for homes in Northglenn or Westminster where the particulate load is different. Call (844) 685-6342 to confirm whether your address falls within the zone where this treatment is advised.
