We’ve been cleaning HVAC systems in Clovis for 17 years. We know the 93619 tract homes with their two-story duct networks, the 1970s ranches off Clovis Avenue with original flex duct, and the particular grime that valley agriculture leaves behind. This isn’t generic maintenance — it’s Clovis-specific work.
Why Redwood Air Duct Cleaning Service Fresno Is Clovis’s Preferred HVAC Cleaning Company
Our reputation in Clovis is built on showing up and doing the work ourselves. Ryan Bell — owner and lead technician — personally leads every HVAC cleaning job. That means 17 years of pattern recognition walks through your door, not a trainee with a rented machine. Our 821 verified reviews hold a 4.9-star average, and a significant share come from Clovis homeowners who’ve had us back multiple times.
We respond to Clovis calls fast because we’re already nearby — Fresno to Clovis is a straight shot on Herndon or Shaw Avenue. Most Clovis appointments book within 24–48 hours, and same-day service is often available during our peak fall season after almond harvest wraps up.
We understand Clovis housing in a way that out-of-town franchises don’t. We’ve cleaned evaporator coils in 2010s tract homes near Loma Vista and pulled failed flex duct from 1970s ranches near Old Town. We know which 93619 developments used the same builder-grade ductwork, and which 93611 neighborhoods are hitting the age where original systems start failing. That local knowledge changes what we find — and how we fix it.
Our HVAC Cleaning Services in Clovis
Evaporator Coil Cleaning
The evaporator coil in your Clovis home works harder than coils in most of the country. Sixty to seventy days above 100°F annually means your AC runs almost continuously from May through September, pulling valley air through the system. That air carries agricultural dust from almond and citrus operations, wildfire PM2.5, and the fine particulate that tule fog traps against the valley floor. Over seasons, this bakes onto the coil.
In newer 93619 tract homes, we frequently find post-construction drywall dust has fused to the coil surface during those brutal summers. Surface cleaning won’t touch it. We use professional Nikro equipment and apply coil treatment to break down baked-on deposits without damaging the delicate fins. A clean coil in Clovis can improve airflow 15–25% and cut cooling costs measurably.
Coil Treatment
Standard cleaning isn’t always enough for Clovis conditions. When we find coils caked with tan-gray agricultural grime — common in homes east of Clovis Avenue where almond harvest dust infiltrates attic spaces — we apply specialized treatment. This isn’t a spray-and-rinse job. We use Abatement Technologies products formulated to dissolve baked particulate without corroding aluminum fins.
The treatment step matters especially for homes near active orchards. If we clean your coil in October after harvest season but skip treatment, you’re likely calling us back by next spring. We see this pattern repeatedly in 93611 and 93612 ZIP codes. Proper treatment extends the cleaning’s effectiveness through multiple valley summers.
Air Handler Cleaning
Your air handler is the lungs of the system — blower, housing, and filter chamber. In Clovis, these components accumulate debris at accelerated rates. The blower wheel especially: agricultural dust is abrasive and unbalanced, and an unbalanced blower strains the motor, increases energy draw, and shortens equipment life.
We disassemble and clean the entire air handler assembly using Rotobrush systems that meet NADCA standards. For two-story homes common in 93619, the air handler works harder to push air through extended duct runs, so cleanliness matters more. We’ve restored airflow in systems where homeowners were told they needed replacement — when they really needed thorough cleaning.
Blower Cleaning
The blower wheel deserves its own attention in Clovis. Valley dust is fine enough to pass through standard filters and stick to spinning blades. Each layer reduces efficiency. We remove the blower assembly entirely — not just vacuum around it — and clean each blade and the motor housing. This is standard on every HVAC cleaning we perform, because skipping it means leaving the problem in place.
Condenser Cleaning
Your outdoor condenser faces the same particulate load, plus what the wind carries. Cottonwood fluff from valley trees, agricultural debris, and plain dust clog the fins. We clean condenser coils with low-pressure, high-volume methods that won’t flatten the fins. In Clovis’s heat, a clean condenser can mean the difference between keeping up on 105°F days and running continuously without reaching setpoint.

Heat Exchanger Cleaning
For gas furnaces — common in older 93612 and 93611 homes — the heat exchanger needs inspection and cleaning before winter tule fog season seals homes tight. Cracked or sooted exchangers are a safety issue; we check carefully and clean thoroughly so your system runs clean through the months when recirculated air is your only air.

Trusted Brands We Service in Clovis
We clean and service HVAC systems carrying Honeywell, Aprilaire, and other major control and filtration brands. For air quality and sanitizing work, we use Abatement Technologies products — the same formulations specified for commercial remediation. Our Rotobrush and Nikro equipment is what the industry actually specifies for duct cleaning, not consumer-grade vacuums with marketing attachments.
Because we’re owner-operated and local, we don’t wait on corporate parts warehouses. When a Clovis job needs a specific component — a replacement coil for a common 2000s-era builder unit, a blower motor for a furnace in an Old Town ranch — we source fast and return to complete the work. No handing you off to another contractor.
Common HVAC Cleaning Problems We See in Clovis Homes
- Collapsed original flex duct in 1970s–1980s ranches. In 93612 and 93611 near Old Town, we regularly find flex duct that has sagged or collapsed under its own weight, creating particulate reservoirs no vacuum can reach. Standard cleaning won’t fix this — we identify it and recommend retrofit options.
- Baked-on coil grime in 2000s–2010s tract homes. The 93619 growth corridors produced thousands of large homes with extensive duct systems. Post-construction drywall dust, baked by 100°F+ summers onto evaporator coils, requires treatment beyond surface cleaning.
- Post-harvest recontamination from unsealed duct penetrations. Almond harvest dust infiltrates attic spaces through gaps around duct boots and plenums. We clean the system, then seal the entry points — otherwise next August’s harvest undoes our work within weeks.
- Tule fog season allergy spikes from dirty systems. When December through February fog seals Clovis homes tight, recirculated air quality depends entirely on system cleanliness. We see predictable winter call spikes from 93611 and 93612 residents whose symptoms trace directly to neglected ductwork.

What moves you within these ranges? System accessibility matters — attic air handlers in 93619 two-story homes take more time than garage units. Coil condition matters — light dusting versus baked agricultural grime changes the approach. Duct length and configuration matter — the extensive systems in 3,000+ sq ft northeast Clovis homes simply have more surface area.

FAQs — HVAC Cleaning in Clovis
Your filter doesn’t catch what enters through attic duct penetrations. Almond harvest (August–October) kicks up extraordinary dust clouds east and north of Clovis that infiltrate gaps around duct boots, plenums, and access panels while your AC is still running hard. We routinely pull filters and duct debris that are visibly tan-gray from this agricultural particulate. A new filter helps, but sealing the infiltration points is what stops the cycle. Call (855) 643-8783 and we’ll identify where your system is pulling in outside air — estimates are free.
Cleaning helps temporarily, but original flex duct from that era is often past its functional life. In 93612 and 93611, we regularly find flex that has sagged, collapsed, or developed particulate traps no cleaning can fully clear. We assess honestly: if the duct is structurally sound, cleaning and sealing extends its life. If it’s collapsed or degraded, we recommend retrofit to rigid ductwork — we handle both the cleaning and the replacement, so you don’t source multiple contractors. Call (855) 643-8783 for an evaluation.
Tule fog seals Clovis homes tight for weeks each December through February, making recirculated air your only air. If your ducts and HVAC components harbor agricultural dust, wildfire residue, or mold spores, you’re breathing concentrated doses of it. Our winter-season HVAC cleaning calls in 93611 and 93612 spike precisely when this happens — residents report worsened allergy symptoms from old flex duct reservoirs that have been loading contaminants all year. Pre-fog cleaning (October–November) prevents this. Call (855) 643-8783 to schedule before the fog sets in.
Two-story duct systems require longer hose runs and more powerful equipment, which is exactly why we use professional Rotobrush and Nikro systems rather than consumer-grade machines. The 93619 developments built in the 2000s–2010s typically have extensive duct networks serving 2,000–3,500 sq ft, often with separate zones. We clean the full system, including the longer return runs that tend to accumulate more debris. No special scheduling needed — this is standard work for us. Call (855) 643-8783 for a free estimate.
Before. Your system works hardest from May through September, and starting that season with clean coils, a balanced blower, and sealed ductwork means better efficiency when you need it most. Post-harvest (October–November) is ideal — we clean out the accumulated agricultural dust and wildfire residue, then you’re set for winter fog season too. That said, if your system is struggling now, don’t wait. Call (855) 643-8783 — we often have same-day availability for urgent Clovis calls.
