Clovis sits where the city ends and the fields begin. That geography defines what we pull out of local ductwork. Homes near Temperance Avenue, Shepherd Avenue, and the eastern reaches of 93619 back directly against almond orchards and cotton fields. Agricultural dust, harvest debris, and field-stir particulates load HVAC systems here at rates that would surprise technicians from coastal markets. Layer on the San Joaquin Valley’s thermal inversions, which trap wildfire smoke and PM2.5 at ground level for weeks, and you’ve got a duct system working harder and getting dirtier faster than the manufacturer ever intended.
Our HVAC Cleaning team runs regular routes through Clovis, with same-day and next-day availability for most calls. We answer the phone 24 hours a day - a live person, not a voicemail tree.
Why Bellows Air Duct & Vent Co. Is Clovis’s Preferred HVAC Cleaning Company
We’ve been cleaning HVAC systems in Fresno County since 1984, and Clovis has been central to our service territory from the start. Our technicians know the difference between a 1990s tract home off Willow Avenue with original flex duct and a 2005 build near Clovis East High with attic systems already showing thermal degradation. That local knowledge means faster diagnosis, no guesswork, and no returning with “the wrong part.”
Clovis homeowners call us back because we show them the problem before we quote the fix. Every job starts and ends with a camera inspection - a visual record of what was in there and what’s gone. Our 90-Day Done Right Promise is stamped on every invoice: if it’s not right, we return at no charge with no paperwork required.
Background-checked, uniformed technicians arrive in marked vehicles. Pricing is disclosed before a single tool is lifted - the number on the phone is the number on the invoice. No bait coupons, no scare tactics, no price changes at the door.
Ray Castillo, who leads Bellows Air Duct & Vent Co., built this operation on a simple standard: one honest price, shown before we start. That hasn’t changed in four decades.
Our HVAC Cleaning Services in Clovis
Evaporator Coil Cleaning
The evaporator coil in your Clovis home sits in a dark, damp environment that agricultural dust loves to colonize. When that fine silt from nearby orchards coats the coil fins, airflow drops and the system runs longer to hit the thermostat setpoint - sometimes 20-30% longer. We clean coils with professional-grade foaming agents and low-pressure rinses that restore heat transfer without damaging delicate aluminum fins. In Clovis, we often recommend mid-season coil checks for homes within a half-mile of active fields, particularly in 93619.
Blower Cleaning
The blower wheel is the engine of your airflow, and in Clovis it works overtime. Six months of continuous operation from May through October means the blower is spinning nearly non-stop, pulling valley particulates through the return. A dirty blower wheel throws off balance, increases amp draw, and pushes less air to every room. Our crew removes the assembly, cleans the wheel and housing with Nikro vacuums and compressed air, and verifies factory-spec RPM and amp draw before reassembly. Most Clovis blower cleanings run $180-$320 as a standalone service.
Heat Exchanger Cleaning
Gas furnace heat exchangers in Clovis collect the same fine dust that coats everything else, but with a critical difference: restricted airflow here can cause incomplete combustion and carbon monoxide risk. We inspect heat exchangers with cameras and fiber-optic scopes, clean primary and secondary cells without compromising metal integrity, and test combustion efficiency before we leave. This is not a homeowner job - the metal is thin, the consequences of damage are severe, and California code requires documented inspection on any furnace service that disturbs the exchanger.
Condenser Cleaning
Your outdoor condenser in Clovis battles cottonwood fluff, almond blossom debris, and the fine dust that settles on everything east of Clovis Avenue. A dirty condenser coil can’t reject heat effectively, so head pressures climb and compressor life shortens. We fin-comb damaged coils, apply foaming cleaner, and rinse with controlled pressure - never a power washer, which folds fins flat. Condenser cleaning in Clovis runs $140-$240 and is often paired with evaporator service for complete system restoration.
Air Handler Cleaning
The air handler cabinet houses your blower, coil, and filter rack - the junction where return air becomes conditioned air. In Clovis’s older 93611 subdivisions, we frequently find handler cabinets pulling attic air through degraded door gaskets and penetrations. Our cleaning includes cabinet sanitizing, gasket inspection, and seal verification. If the handler is drawing unconditioned attic air, we’ll show you on camera and quote the fix before we proceed.

Trusted Brands We Service in Clovis
We clean and maintain systems built around Honeywell, Aprilaire, and Nikro equipment - the same brands serious HVAC contractors specify for new installations. Our vans carry common replacement parts for Clovis service calls, so most jobs finish in a single visit without waiting on a warehouse run to Fresno. For specialized components in newer high-efficiency systems, our parts network typically delivers next-day to 93619 and 93611.
Common HVAC Cleaning Problems We See in Clovis Homes
- Agricultural dust overloads filters mid-season. The almond harvest and field cultivation east of Clovis Avenue generate particulate loads that standard 1-inch fiberglass filters cannot handle. We upgrade Clovis customers to pleated media or whole-house Aprilaire filtration systems that capture finer particles without choking airflow.
- Attic heat destroys flex duct collars in 15-20 years. Those 150-160°F attic temperatures in Clovis’s master-planned subdivisions cook the mastic and zip-tie connections on flex duct runs. A failed collar turns your duct system into a vacuum for attic insulation fibers and concentrated agricultural dust.
- Thermal inversions compress cleaning intervals. The Central Valley’s winter Tule fog and summer smoke inversions trap PM2.5 at breathing level for days. Clovis systems accumulate contamination faster than standard manufacturer maintenance schedules anticipate - often requiring cleaning at 60-70% of the typical interval.
- Sagged flex duct runs in 93619 pull insulation into supply registers. On a 2005-built home near Temperance Avenue and Shepherd Avenue in 93619, our crew found flex duct collars deteriorated from 150°F attic cycles; a Rotobrush inspection revealed a sagged run pulling attic insulation fibers into the living room supply registers. We replaced two failed collars and performed a full HVAC Cleaning with a Nikro vac, restoring airflow and eliminating the dust odor.
Pricing for HVAC Cleaning in Clovis, CA
A complete HVAC Cleaning in Clovis runs $280-$580 depending on system size, accessibility, and contamination level. Here’s how typical services break down:

FAQs - HVAC Cleaning in Clovis
Most Clovis homes need HVAC cleaning every 18-24 months, compared to the 3-4 year interval typical in non-agricultural areas. Homes within a half-mile of active orchards or fields, particularly in 93619 and eastern 93611, often benefit from annual service. The almond harvest season - August through October - is the heaviest loading period; scheduling a pre-harvest inspection in July lets us catch filter and coil conditions before peak stress. Call (844) 685-6342 to set up a reminder schedule - we’ll call you when it’s due.
No. A standard HVAC cleaning removes contamination but does not restore structural failures in the duct system itself. Sagging or separated flex duct requires physical repair - collar replacement, support strap installation, or in severe cases, duct replacement. We camera-inspect every system before cleaning, so if we find failed collars in your 93619 attic, we’ll show you the footage and quote the repair separately. The cleaning and the repair are distinct operations, and we won’t sell you one when you need both. Call (844) 685-6342 for an inspection that finds the real problem.
Yes. The inversion layer traps fine particulates - PM2.5 from wildfire smoke, ag operations, and road dust - at ground level where your intake pulls them in. These particles are smaller and more deeply embedded than typical household dust, so we use higher-CFM Nikro vacuums and more aggressive agitation tools in Clovis than we might in coastal markets. The method adapts to what’s actually in your ducts, not a generic protocol. Call (844) 685-6342 and we’ll explain what our camera found in your specific system.
Gray, fibrous dust at supply registers in Clovis usually indicates attic insulation being pulled into the duct system through a failed collar or separated joint. The 150-160°F attic heat degrades mastic seals over 15-20 years, creating a vacuum leak that draws blown-in fiberglass or cellulose directly into your airflow. This is a common failure mode in 93619’s boom-era subdivisions and shows up on our inspection cameras far more often than in Fresno’s older, shorter-run duct layouts. Cleaning removes the deposited fibers, but the leak must be sealed or the problem returns. Call (844) 685-6342 for a camera inspection that shows exactly where the breach is.
Yes - more important here than in milder climates. Clovis condensers operate under extreme load for six months straight, and the agricultural dust, cottonwood debris, and valley particulates coat the outdoor coil faster than in urban environments. A dirty condenser can raise head pressure 20-30%, increasing energy consumption and shortening compressor life. We recommend annual condenser inspection for Clovis homes, with cleaning as needed. The $140-$240 service pays for itself in efficiency and longevity. Call (844) 685-6342 to schedule - estimates are free.
