Fast, Reliable Air Quality & Ventilation Across Clovis
Air quality and ventilation work in Clovis runs about $350 to $3,000 depending on whether you’re adding a media filter cabinet, a UV purifier, or a full ERV system. Most installs take a single day, and we stock parts for nine major brands so there’s no waiting on a Fresno warehouse run. Call us at (855) 467-1888 for a free estimate.
We’ve been driving out to Clovis from Sacramento for 16 years, and we know the difference between a 93612 bungalow near Old Town and a 93619 foothill tract in Harlan Ranch. Jason Trent, our owner and field supervisor, personally reviews every air quality job that crosses the Sierra Nevada divide. That means the technician who shows up at your door has already been briefed on whether your home was built during the 1990s stucco boom or the 2004–2009 two-stage HVAC wave, and what that means for your filtration and ventilation options.
Why Stonegate Heating & Air California Is Clovis’s Preferred Air Quality & Ventilation Company
Our Air Quality & Ventilation team has completed hundreds of jobs across Clovis’s four ZIP codes — 93611, 93612, 93613, and 93619. We’ve replaced media cabinets in Tarpey Village, added UV purifiers to systems along Willow Avenue, and sized ERV units for homes backing up to active almond orchards where agricultural dust is a daily reality.
Sixteen years in business, nearly 500 reviews at 4.7 stars. That volume matters because it means we’ve seen the specific failure patterns that repeat across Clovis neighborhoods. We don’t guess.
Jason Trent supervises every project as field supervisor, not from a desk in Sacramento. When you’re dealing with attic-mounted air handlers in 150°F summer heat or sizing filtration for a property that borders a working horse ranch, that on-site accountability changes outcomes.
We carry factory-authorized parts and training for Carrier, Trane, Lennox, Goodman, and five other major brands. Whatever system is in your Clovis home, we service it.
Our Air Quality & Ventilation Services in Clovis
Air Filtration
Clovis sits at the wrong end of the San Joaquin Valley’s air basin. PM2.5 and ozone levels here rank among the nation’s worst, and that’s before you factor in acreage properties with orchard dust, horse arena particulate, or construction debris from the still-expanding 93619 subdivisions. Standard 1-inch fiberglass filters clog in weeks, not months.
We install 4-inch media cabinets with MERV 11 to MERV 13 filters, sized to your system’s static pressure capacity. In Harlan Ranch and similar 2004–2009 builds, we often pair this with a variable-speed blower upgrade because the original single-speed motors can’t handle the resistance of proper filtration. A typical media cabinet install in Clovis runs $350–$600.
UV Air Purifier
Tule fog season in Clovis — December through January — creates persistent moisture inside attic-mounted air handlers. That dark, humid environment breeds microbial growth on coils and in drain pans. A UV-C lamp mounted in the return plenum or directly over the evaporator coil destroys that growth before it circulates through your ducts.
We spec UV systems that don’t produce ozone, and we position them where they’ll actually hit the target surfaces, not where they’re easy to wire. UV air purifier installation in Clovis typically costs $400–$800. For homes near agricultural operations where organic particulate is high, this is often the single most noticeable upgrade a homeowner makes.
Ventilation Install
Clovis’s tight, stucco-and-tile tract homes — especially those built 1992–2015 — were constructed for energy efficiency, not breathability. Kitchens, bathrooms, and attached garages recirculate stale air, VOCs, and combustion byproducts. In eastern 93619, wind-driven dust infiltration makes the problem worse: you can’t open windows without coating every surface.
We install ERV and HRV systems that exchange stale indoor air for filtered outdoor air while recovering thermal energy. For a typical 2,000-square-foot Clovis home, ERV/HRV system installation runs $1,500–$3,000. Homes with detached workshops or ADUs may need dedicated ventilation runs, which we size separately.
Humidifier & Dehumidifier Install
Clovis’s climate swings hard. Summer humidity rarely cracks 30%, drying sinuses and cracking woodwork. Tule fog season reverses that, with sustained 80–90% humidity that overwhelms standard HVAC dehumidification. We install whole-house humidifiers on furnaces and dedicated dehumidifiers for problem zones like converted garages or basement-level bonus rooms.

Trusted Brands We Service in Clovis
We maintain active training and parts access for Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. That matters in Clovis because the 2004–2009 building boom standardized on specific builder-contract brands by subdivision. Harlan Ranch, for instance, shipped overwhelmingly with single OEM equipment. When we roll to a service call there, our techs already know what they’re walking into, and our trucks carry the common failure parts for those specific vintages. No “we’ll have to order that and come back next week.” One trip.
Common Air Quality & Ventilation Problems We See in Clovis Homes
- Orchard dust overwhelms standard filters. Properties near active almond, pistachio, or citrus operations — common in 93619 and rural 93611 — see 1-inch filters turn black in three weeks. Homeowners often don’t check until the system ices up from restricted airflow.
- DIY MERV upgrades burn out blower motors. Self-reliant Clovis homeowners see “MERV 13” at the hardware store and install it in systems rated for MERV 8. The static pressure spike overworks the motor. We see this weekly in 1990s and early-2000s builds with original single-speed blowers.
- Attic-mounted air handlers cook in summer heat. Clovis attics hit 140–155°F. That heat degrades refrigerant lines, cracks drain pans, and bakes filter media into the grille. We regularly find filters that have physically warped and created bypass gaps.
- Cluster failures in master-planned communities. In Harlan Ranch and similar 93619 subdivisions, entire cul-de-sacs were built with identical two-stage systems from a single 18-month builder contract. Those systems now fail within weeks of each other, creating block-wide replacement waves we’ve learned to anticipate.

FAQs — Air Quality & Ventilation in Clovis
Harlan Ranch was built almost entirely between 2004 and 2009 under a single builder contract that specified identical two-stage HVAC equipment across the subdivision. Those systems are now 16–20 years old and hitting end-of-life simultaneously. We’ve replaced three units on the same cul-de-sac in one week because the entire neighborhood was commissioned within an 18-month window. If your Harlan Ranch home still has original equipment, it’s worth having us inspect before peak summer hits. Call (855) 467-1888 for a free assessment.
Start with MERV 11 in a 4-inch media cabinet, not a 1-inch pleat. MERV 13 is better for dust but only if your blower can handle the static pressure. Many 1990s–2000s Clovis systems can’t. We measure actual pressure drop before recommending anything higher. For acreage properties with active orchard or horse operations, we often pair MERV 11 with a UV purifier rather than pushing filtration alone. Call us and we’ll test your system.
Yes, if you use solvents, generate combustion byproducts, or store chemicals. Detached workshops in Clovis’s rural 93611 and 93619 areas often lack any mechanical ventilation, and opening a window isn’t practical during dust season or Tule fog events. We install dedicated ERV or exhaust ventilation sized to your shop’s cubic footage and use pattern. It’s a separate calculation from your home’s system.
Tule fog creates sustained high humidity from December through January, which condenses in attic-mounted air handlers and drain pans. That moisture feeds microbial growth on coils and in ductwork. We address this with UV purifiers, proper condensate drainage, and in some cases dehumidifier integration. The fog itself also traps particulate, so your filtration works harder during these months. Check filters monthly in winter, not just summer.
Yes, if there’s adequate clearance in the return plenum or above the coil. We mount low-profile UV lamps in tight spaces and wire them to dedicated circuits. Older furnaces in Clovis’s 1990s builds often have more plenum room than you’d expect. The bigger question is whether your blower and ductwork are clean enough that the UV light has a clear shot at the surfaces it needs to treat. We inspect before we quote. Call (855) 467-1888 for a free estimate.
