Fast, Reliable Air Quality & Ventilation Across West Hills
Air quality and ventilation work in West Hills demands more than off-the-shelf equipment. We’re talking about a neighborhood where your attic hits 150°F in July, where Santa Ana winds blast particulate through the Santa Susana Pass, and where that 1960s ranch on Roscoe Boulevard has ductwork leaking 30% of its conditioned air before it ever reaches your bedroom. Our Air Quality & Ventilation team has been responding to West Hills calls for nearly two decades, and we’ve learned that IAQ upgrades here only work when you seal the envelope first. Call (844) 560-6978 for a free estimate. We’ll get to you from San Jose with same-day availability when your system’s struggling.
Why Crestview Heating & Air California Is West Hills’s Preferred Air Quality & Ventilation Company
West Hills homeowners aren’t looking for a dispatcher reading from a script. They’re looking for someone who’s crawled through enough 91307 attics to know that the flex duct from 1972 crumbles at the touch. Marcus Feldman, our owner and Service Manager, still manages jobs in the field personally. That means when you call Crestview, you’re getting ownership-level accountability built into the daily operation, not a franchise technician three weeks out of training.
Our 4.8-star average across 250+ customer reviews reflects real-world performance on real West Hills systems. We’ve serviced homes along Fallbrook Avenue where original construction left returns undersized by half, and we’ve balanced zoned systems in the foothills near Santa Susana Pass where elevation changes create 15-degree temperature swings between floors. From emergency calls to commercial buildouts, we bring nearly two decades of HVAC experience to every job. Your system, our specialty — including the nine major brands we factory-train on so no West Hills customer gets told “we don’t work on that.”
Our Air Quality & Ventilation Services in West Hills
ERV & HRV System Installation
West Hills’s thermal isolation makes energy recovery ventilation essential. Without marine-layer cooling, homes here run tight and hot, and opening windows in August is pointless. An ERV pre-cools incoming fresh air using your exhaust stream, cutting the load your AC fights. In the 1980s–1990s custom-home foothills near Santa Susana Pass, we retrofitted a zoned Carrier system with an ERV, matching the precise duct connections to prevent cross-contamination from the unshaded attic that routinely hits 150°F. The homeowner now sees balanced humidity between his lower-level living spaces and upper master suite — a common issue in these elevation-change properties. Most West Hills ERV installations run $2,800–$4,500 depending on existing duct configuration and whether we need to add dedicated ventilation ductwork.
Air Filtration System Upgrades
Here’s the hard truth about West Hills air filtration: that MERV 13 you’re proud of is working against you if your ducts leak 30%. We’ve measured it. In 91308, a homeowner near Saticoy Street was changing filters every three weeks during Santa Ana events, wondering why the blower motor was failing. We sealed his flex duct first, then sized a 5-inch media cabinet properly to his airflow. Filter life tripled. Pressure drop normalized. For homes in the Santa Susana Pass corridor where particulate loads spike, we typically recommend whole-house media filtration ($650–$1,200 installed) paired with duct sealing, not a standalone upgrade that fights itself.
Dehumidifier Installation
West Hills isn’t humid by coastal standards, but that 1960s ranch with original construction? The stuffy feel isn’t humidity from outside — it’s moisture trapped in wall cavities and poor air exchange. A whole-home dehumidifier tied to your HVAC ($1,800–$3,200 installed) pulls latent load off your AC, letting it run longer cycles for better filtration without overcooling. We see this especially in the single-story tracts near Platt Avenue where slab construction and minimal ventilation create that clammy sensation even at 78°F. Dehumidifier sizing matters here. Too small and it runs constantly; too large and it short-cycles, doing nothing for your air quality.
UV Air Purifier Installation
UV-C lamps mounted at the coil address microbial growth that thrives in West Hills’s combination of extreme attic heat and temperature differential at the air handler. But again — duct sealing first. We’ve been called to 91307 homes where a previous installer dropped in a UV lamp on a leaky system, and the homeowner couldn’t tell any difference. The UV can’t treat air that never passes the coil because it’s escaping through a collapsed return boot. Proper West Hills UV installation runs $450–$850, always with a coil inspection and usually with duct sealing recommendations we’ll show you with a camera.

Trusted Brands We Service in West Hills
We stock parts and train factory-direct on Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For West Hills customers, that means no waiting on a Lennox ERV core or a Rheem humidifier solenoid to ship from a distant warehouse. We carry common filtration media, UV lamps, and ERV cores for the brands we see most in this market. Your system, our specialty — and that specialty includes knowing that the Carrier ERV installed in a 1992 custom home near Bell Canyon has different connection geometry than the current model, and planning accordingly.
Common Air Quality & Ventilation Problems We See in West Hills Homes
- Mastic seal degradation in superheated attics. Ductwork in West Hills attics reaches 150–160°F regularly, and the mastic applied in 1974 has turned to powder. We find 25–35% leakage as standard on pre-1985 systems. Sealing those runs often delivers more comfort improvement than replacing the air handler.
- Santa Ana wind particulate overwhelming filtration. The topographic funnel through Santa Susana Pass channels intense wind events that load MERV 13+ filters in weeks, not months. Blower motors strain, energy bills spike, and homeowners blame the filter quality rather than the local climate reality.
- Undersized returns in original ranch construction. Those 1960s–70s tract homes were built for 3-ton systems with 14-inch returns. Modern equipment and IAQ add-ons need more airflow. We measure static pressure and often find returns choking the system by 30% or more.
- Zoned system imbalance in hillside custom homes. The elevation-change properties near the Santa Monica Mountain foothills have dampers that were never properly commissioned. Upper floors over-ventilate, lower floors stagnate, and no humidifier or purifier can fix a distribution problem.

FAQs — Air Quality & Ventilation in West Hills
West Hills sits in a natural heat trap where the Simi Hills, Santa Susana Mountains, and Santa Monica Mountains converge, blocking virtually all marine-layer cooling — producing peak summer temperatures of 105–112°F that routinely exceed neighboring coastal-influenced cities by 25°F or more. Woodland Hills gets modest afternoon ocean influence; West Hills gets none. An ERV pre-cools and dehumidifies incoming fresh air using your exhaust stream, which matters enormously when your AC runs 14 hours daily in August. Without it, you’re either suffocating in a sealed box or paying to condition 100°F outside air. Call (844) 560-6978 and we’ll measure whether your home’s tightness and runtime justify the investment.
Yes, but only if your ducts are sealed first. That stuffy sensation in original West Hills ranch construction comes from moisture trapped in wall cavities and minimal air exchange, not from high outdoor humidity. A dehumidifier tied to your HVAC will reduce latent load and let your system run longer, more effective cycles. We’ve installed dozens in the tracts near Platt Avenue and Fallbrook Avenue where slab construction compounds the problem. Expect $1,800–$3,200 installed, with duct sealing often bundled. Call for a free assessment of your specific home.
Switch to a properly sized 5-inch media cabinet with lower pressure drop, and seal your ducts immediately. The Santa Ana winds funneled through Santa Susana Pass spike particulate loads that overwhelm standard 1-inch filters, especially when your system is pulling unfiltered attic air through leaks. We’ve solved this exact issue for Carrier homeowners in 91307 and 91308. The media holds more debris with less airflow restriction, and sealed ducts mean all your air actually passes through it. Call (844) 560-6978 for filter sizing and duct inspection — estimates are free.
Yes. Modern Lennox zoning controls integrate with major smart-home platforms, and we’ve commissioned these systems in the hillside pockets near Santa Susana Pass where elevation changes create complex balancing needs. The key is proper damper calibration first, then adding the control layer. Smart integration without balanced airflow just automates an uncomfortable house. We can assess your current zoning performance and recommend the right integration path. Call to schedule with Marcus Feldman directly.
Relocate critical components to conditioned space where possible, and specify high-temp-rated materials when attic installation is unavoidable. For West Hills’s 150–160°F attics, we use mastic rated to 200°F, insulate ERV ductwork to R-8 minimum, and often recommend moving media cabinets to return plenums in closets or garages. UV lamps need heat-resistant ballasts. Every component we install in your attic is selected for this specific thermal environment, not generic California conditions. Call (844) 560-6978 for equipment placement recommendations during your free estimate.
