Why Crestview Heating & Air California Is Agoura’s Preferred Air Quality & Ventilation Company
We’ve built our reputation in Agoura by showing up with actual answers, not sales scripts. Owner Marcus Feldman still manages jobs in the field as Service Manager, so the accountability doesn’t stop at the office door. That matters here more than most places, because Agoura’s split housing stock — pre-fire legacy homes versus post-2018 rebuilds — creates problems that textbook training doesn’t cover.
Our 250+ verified reviews average 4.8 stars, and a significant share come from Agoura Hills and Westlake Village customers who found us after frustrating experiences with dispatch-heavy competitors. When you’re dealing with smoke-damaged blower wheels or Title 24 compliance on a rebuild, you want the technician to have backup from someone who’s made those calls before. Marcus has, for 19 years.
We stock parts for Trane, Lennox, Goodman, and Rheem systems locally, which means faster turnaround on repairs that can’t wait through another Santa Ana event. From emergency calls to commercial buildouts, your system is our specialty.
Our Air Quality & Ventilation Services in Agoura
Air Filtration
Agoura’s valley geography traps particulate matter from wildfire seasons past and present. We install MERV-13+ filtration systems that meet California’s evolving standards for smoke readiness. In older Agoura homes with leaky return plenums, filtration upgrades fail if the ductwork isn’t addressed first. We test static pressure and seal returns before recommending filter upgrades, because a MERV-13 filter in a leaky system is like a screen door on a submarine.
ERV/HRV System Installation
Energy Recovery Ventilators and Heat Recovery Ventilators solve the core tension in Agoura: you need fresh air, but you can’t just throw open windows during fire season. In the post-Woolsey rebuild on Cornell Road, we installed an ERV with MERV-13 filtration and a motorized fresh-air damper that closes during fire events, because the homeowner’s year-old Lennox system was already pulling ash-laden air through every leak. The old attic air handler’s blower wheel was packed with fire-season debris — a one-hot-day failure waiting to happen. ERVs in Agoura must be specified with fire-event sealing capability; we don’t install them without it.
Ventilation Install
Proper ventilation in Agoura means designing for two realities: normal shoulder-season operation and emergency smoke-sealing mode. We install controlled fresh-air intake systems with motorized dampers that close automatically when outdoor air quality drops. For post-Woolsey rebuilds in the 91301 zip code, we coordinate with your builder to ensure VHFHSZ-compliant penetrations and Title 24-mandated ventilation rates. Older homes get retrofitted with the same smoke-sealing logic, adapted to existing duct infrastructure.
Humidifier Installation
Agoura’s dry Santa Ana wind events drop indoor humidity into the teens, cracking woodwork and irritating respiratory systems already stressed by fire-season particulate exposure. We install whole-home humidifiers integrated with your central system, sized for the rapid humidity swings this valley gap produces. Bypass and steam options both available, with preference for steam units in homes where the furnace runs intermittently during mild winters.
Dehumidifier Installation
Summer humidity spikes in Agoura are brief but intense, particularly in homes with crawl spaces or basement-adjacent foundations near the creek beds off Chesebro Road. We install whole-home dehumidifiers that integrate with your central air handler, preventing the mold and musty odors that develop when cooling systems short-cycle during shoulder-season humidity events.
UV Air Purifier Installation
UV-C lamps target biological growth on wet evaporator coils — a real concern in Agoura homes where ash particulate provides nucleation sites for mold and bacteria. We install UV purifiers as coil-mounted systems, not the gimmicky in-duct wands that miss the actual problem. For homes with persistent post-fire odor issues, UV combined with activated carbon filtration addresses what filters alone cannot.

Trusted Brands We Service in Agoura
We service and stock parts for nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. In Agoura specifically, we see a lot of Trane and Lennox equipment in post-Woolsey rebuilds, where builders specified these brands for their warranty support and Title 24 compliance documentation. Goodman and Rheem dominate the older stock — reliable workhorses that have lasted 20+ years but are now due for filtration and ventilation upgrades their original installers never contemplated. We carry common parts for all four brands on our trucks, which means no waiting for a warehouse run when your system fails on the first 105°F day of summer.
Common Air Quality & Ventilation Problems We See in Agoura Homes
- Fire-season ash packed in blower wheels and evaporator coils. Technicians working the post-Woolsey call-back wave routinely find blower wheels packed with fire-season ash — systems that tested fine on paper but are one hot day away from failure. We pull and clean blower assemblies as standard practice on every Agoura service call, not just when symptoms appear.
- Original 1970s–80s ductwork leaking attic air into living spaces. The core of Agoura’s housing stock is 1970s–1990s suburban tract development with original or once-replaced ducted central HVAC systems. That attic air handler is pulling through R-6 flex duct that’s degraded at every joint, sucking superheated, ash-laden attic air straight into your breathing space. Filtration upgrades are wasted money until this is sealed.
- Post-Woolsey condensers with weakened capacitors failing on first extreme heat day. Condensers that ‘survived’ the fire but inhaled months of particulate-laden air develop capacitor degradation that’s invisible until Sundowner winds spike temperatures 25°F in hours. We test capacitance and contactor condition on every tune-up, and we find this problem more often in Agoura than any nearby city.
- Cracked secondary heat exchangers from extreme thermal events. The Woolsey Fire’s radiant heat stressed heat exchangers in homes that never actually burned. We’ve replaced cracked secondaries in Agoura homes where the furnace “worked fine” through mild weather, then dumped carbon monoxide when finally loaded during a cold snap. This is why we perform combustion analysis, not just visual inspection.

FAQs — Air Quality & Ventilation in Agoura
MERV-13 is the minimum filtration level that captures wildfire smoke particles (0.3–1.0 microns), which standard MERV-8 pleated filters miss entirely. In Agoura specifically, the Woolsey Fire deposited ash in ductwork that still recirculates during Santa Ana wind events, and the valley gap concentrates particulate matter from ongoing regional fires. We size MERV-13 systems for your air handler’s static pressure capability, because forcing a filter upgrade onto undersized ductwork kills airflow and burns out blower motors. For a filtration assessment specific to your system, call (844) 560-6978 — estimates are free.
If your Agoura home survived the fire and still has original flexible ductwork, replacement or comprehensive sealing should be your first priority before any filtration upgrade. The R-6 flex duct common in 1980s Agoura tracts degrades at every joint and collar, creating return-side leaks that pull attic air — including residual ash — directly into your breathing space. We’ve tested homes in Agoura where 35% of return air was coming from the attic, not the rooms. Duct replacement runs $4,500–$12,000 depending on home size, while Aeroseal sealing runs $1,800–$4,500 and addresses most leakage without demolition. Call (844) 560-6978 for duct leakage testing that shows your actual numbers.
A motorized fresh-air damper is a controllable vent that brings in outside air for ventilation, then seals tight when outdoor conditions turn hazardous. In Agoura, you need one because the same Santa Ana and Sundowner wind events that spike your cooling load also carry wildfire smoke from fires that may be fifty miles away. Without automatic sealing, your “ventilation” system becomes a smoke delivery system. We install dampers with AQMD-recommended controls that close based on PM2.5 sensors or manual override, integrated with your ERV or central air handler. Installation typically runs $1,400–$3,800 as part of a ventilation upgrade. Call (844) 560-6978 to discuss smoke-sealing options for your home.
California Title 24 requires mechanical ventilation in all new construction, with specific fresh air rates based on home size and occupancy, and mandates high-efficiency filtration in wildland-urban interface zones like Agoura’s VHFHSZ areas. For post-Woolsey rebuilds in 91301, this means your HVAC contractor must perform Manual J load calculations, install MERV-13 minimum filtration, and provide controlled ventilation that can be sealed during fire events. We coordinate with builders during rough-in to ensure compliance, and we retrofit existing homes to the same standard when owners request it. Title 24 compliance documentation protects your resale value and your family’s air quality. Call (844) 560-6978 for Title 24 ventilation design.
UV-C purification targets biological growth on wet evaporator coils, not smoke particles directly, but it’s valuable in Agoura homes where ash particulate has created persistent mold and bacteria problems on coils and in drain pans. Smoke residue itself is addressed through MERV-13+ filtration and activated carbon, but the biological aftermath — musty odors, coil slime, drain line clogs — is where UV pays for itself. We install UV lamps at the coil surface where they’re effective, not in the return duct where marketing brochures put them. Typical installation runs $650–$1,800. For a combined smoke-residue assessment, call (844) 560-6978.
