Call (844) 560-6978

We’re Crestview Heating & Air California, and our Air Quality & Ventilation team makes the trip up from San Jose to Windsor regularly — usually within a day or two for standard calls, faster for emergency situations. Marcus Feldman, our owner and Service Manager, has spent 19 years in HVAC and knows the specific headaches Windsor homeowners face: aging tract-home ductwork in hot attics, original filter slots too small for modern MERV-13 cartridges, and systems that weren’t designed for the smoke-filled falls that now define Sonoma County life. Call us at (844) 560-6978 for a free estimate on cleaner indoor air.

Why Crestview Heating & Air California Is Windsor’s Preferred Air Quality & Ventilation Company

Our 4.8-star average across 250+ customer reviews didn’t come from generic service calls. It came from showing up prepared — with the right parts for 9 major brands including Trane, Lennox, Goodman, and Rheem — and from Marcus Feldman personally overseeing jobs as Service Manager, not delegating to a rotating cast of subcontractors.

Windsor homeowners specifically tell us they appreciate that we understand their housing stock. Over 70% of Windsor’s housing was built between 1995 and 2005, creating a synchronized wave of 20–30-year-old HVAC systems that reach end-of-life simultaneously, far more concentrated than in Healdsburg or Santa Rosa. When we arrive at a Windsor home, we already know the likely duct layout, the probable filter slot dimensions, and whether the attic run is going to be a 140°F crawl in July. That local familiarity saves diagnostic time and gets your air quality upgrade done faster.

We recently serviced a tract home in the Cloverdale Creek neighborhood near Windsor High School, where the original 2002-era Lennox furnace had a cracked heat exchanger and the R-22 AC was beyond repair. We installed a Carrier 16 SEER system with a MERV-13 filter cabinet, and the homeowner noted the air stayed clean even during the fall Diablo winds. That’s the kind of outcome that earns a 4.8-star rating — and it’s why Windsor customers call us back.

Our Air Quality & Ventilation Services in Windsor

Air Filtration

Windsor’s defining air quality challenge is wildfire smoke infiltration, especially after the 2019 Kincade Fire forced mass evacuations of the town itself. Whole-house air filtration with MERV-13 or better media has become the standard upgrade request here, even on routine tune-up calls. We size filter cabinets to your existing return plenum — critical in 1990s Windsor homes where the original 1-inch slot can’t handle the static pressure of dense pleated media. Typical whole-house filtration upgrades in Windsor run $800–$2,200 installed, depending on whether we need to modify the return duct.

Ventilation Install

Those same 1990s–2000s tract homes were built tight for energy efficiency but without adequate mechanical ventilation. In Windsor, where summer afternoons hit 95–100°F and evenings cool rapidly from marine air, that means stale air gets trapped while your AC cycles hard. We install balanced ventilation systems that exhaust humid, polluted air and bring in filtered fresh air without wrecking your cooling load. Most Windsor ventilation installs fall between $1,800–$3,800, with permits pulled through Sonoma County as required.

ERV/HRV System

Energy Recovery Ventilators (ERVs) and Heat Recovery Ventilators (HRVs) are the right choice for Windsor’s large daily temperature swings. An ERV pre-cools incoming air using your exhausted indoor air in summer, and pre-warms it in winter — critical when your system is already working overtime during Diablo wind events. HRVs handle sensible heat only, better for drier conditions. We size these to your home’s square footage and existing duct capacity, with most Windsor ERV/HRV installations running $2,800–$4,500.

Humidifier Install

Windsor’s fall Diablo winds strip indoor humidity to desert levels, cracking woodwork and irritating sinuses. Whole-house humidifiers integrated with your furnace plenum maintain 35–45% relative humidity through the heating season. Typical installs in Windsor’s 1,500–2,500 square foot tract homes run $650–$1,400.

Dehumidifier Install

While Windsor’s overall climate is dry, poorly ventilated bathrooms, basements, and additions can develop localized moisture problems that feed mold. We install dedicated dehumidifiers with dedicated drains, not the portable units that need constant emptying. Expect $1,200–$2,600 for most Windsor residential applications.

UV Air Purifier

UV-C lamps mounted in your evaporator coil cabinet kill mold and bacteria before they circulate. In Windsor homes where original ductwork has developed leaks in hot attics, this adds a layer of protection against biological contaminants drawn in from unconditioned spaces. UV purifier installs typically run $400–$900.

Trusted Brands We Service in Windsor

We stock parts and filters for Trane, Lennox, Goodman, and Rheem — four of the most common brands found in Windsor’s 1990s–2000s housing stock. Marcus’s factory training across all nine major brands we cover means we don’t turn away jobs because “we don’t work on that.” Your system, our specialty. For Windsor customers, this translates to faster repairs without waiting for specialty parts to ship from Sacramento or the East Bay. We carry MERV-13 cartridges, UV lamp replacements, and ERV core media for the brands we see most often in 95492.

Common Air Quality & Ventilation Problems We See in Windsor Homes

• Original ductwork in unconditioned attics develops leaks from heat cycling. Windsor’s summer attic temperatures regularly exceed 140°F, degrading flex duct seams and allowing unconditioned air — and wildfire smoke — to infiltrate living spaces. We see this in nearly every pre-2005 home we inspect in the Foothill Ranch and Windsor Creek subdivisions.
• MERV-13 filters cause excessive static pressure in undersized original filter slots. Homeowners upgrade filters after fire season, then wonder why their blower motor burns out. The 1-inch slots in most Windsor tract homes can’t handle dense pleated media without system modifications.
• Rooftop condenser coils corrode from ash and debris exposure. After the Kincade Fire, we saw premature coil failures across Windsor, particularly in homes downwind of burned areas. Reduced heat exchange doesn’t just hurt cooling — it degrades whole-system humidity control and air circulation.
• ERV/HRV systems improperly balanced for Windsor’s temperature swings. Units set up for milder coastal climates can’t handle the 40°F+ daily swings common here, leading to comfort complaints and energy waste.
