Fast, Reliable Air Quality & Ventilation Across Los Angeles
Whole-home ventilation and air quality systems in Los Angeles typically cost $2,800–$7,500 to install, with most projects completed in one to two days. If your home lacks existing ductwork, as many older Los Angeles properties do, you’ll also need a HERS-certified rater to verify duct leakage before your permit closes. That’s a California requirement, not optional, and we handle the scheduling.
We serve Los Angeles homeowners and property managers from Koreatown to South Central, including the 90030, 90031, 90032, and 90033 ZIP codes. Our Air Quality & Ventilation team understands the specific challenges of this market: salt-laden coastal air that corrodes metal components, Santa Ana winds that blast fine dust through standard filtration, and pre-war housing stock that was never designed for central air systems. Whether you need an ERV installed in a 1920s bungalow or UV purification for a multi-unit building in Pico-Union, we bring nearly two decades of HVAC experience to your job.

Why Crestview Heating & Air California Is Los Angeles’s Preferred Air Quality & Ventilation Company
Our reputation in Los Angeles is built on showing up for jobs that other companies turn down. We’ve earned a 4.8-star average across 250+ customer reviews, and many of those come from Los Angeles property owners who needed ventilation solutions for buildings without existing duct infrastructure. They found us because we don’t outsource to anonymous technicians — owner Marcus Feldman serves as our Service Manager, which means ownership-level accountability is built into every installation and repair.
Response time matters in Los Angeles, especially during Santa Ana wind events when indoor air quality deteriorates rapidly. We prioritize emergency calls and schedule ventilation assessments within 24–48 hours for non-urgent requests. Our familiarity with Los Angeles’s permit process, including the mandatory HERS rater requirement that out-of-state competitors often miss, keeps your project moving without delays.
Marcus’s 19 years in HVAC includes extensive work on the exact system types found in Los Angeles’s older neighborhoods: floor furnaces, wall heaters, window units, and the ductless mini-splits that often replace them. We’ve factory-trained compatibility across nine major brands, so your system, our specialty. From emergency calls to commercial buildouts, we have the technical range to handle whatever equipment your Los Angeles property requires.
Our Air Quality & Ventilation Services in Los Angeles
ERV/HRV System Installation
Energy Recovery Ventilators and Heat Recovery Ventilators are essential for Los Angeles homes that need fresh air without sacrificing cooling efficiency. In the 90001–90010 corridor, we routinely install ERVs as first-time systems in 1920s–1950s bungalows that never had central ductwork. The job isn’t equipment swap — it’s full duct design from scratch, Title 24 compliance paperwork, and coordination with a HERS-certified rater to verify leakage before permit closure. Salt-laden coastal air corrodes standard ERV cores within 3–5 years, so we specify corrosion-resistant components for Los Angeles installations.
Ventilation Install
We recently retrofitted a whole-house ventilation system in a 1930s Spanish Colonial Revival bungalow on Elm Street in South Central. The home had no existing ductwork, so we designed a new duct system with a Daikin ERV, passed the mandatory HERS duct-leakage test, and sealed it against salt air from the coast. This is typical work for us in Los Angeles. Many contractors assume every home has ducts; we arrive prepared to build ventilation infrastructure where none exists, then navigate California’s third-party verification requirements that don’t exist in Arizona or Nevada.
Air Filtration
Santa Ana wind events in October and November push temperatures above 95°F with single-digit humidity, blasting fine dust and particulates into Los Angeles homes. Standard 1-inch filters can’t handle this load. We size high-MERV filtration systems for these seasonal surges, and we account for the older, leakier envelope construction common in Los Angeles’s pre-war rental stock. Tenants in buildings across South Central and Pico-Union often rely on window units and have never had central ventilation; when we install filtration as part of a new system, we educate them on use and maintenance so the equipment actually performs.
UV Air Purifier
UV-C purification targets biological contaminants that pass through even high-efficiency filters. In Los Angeles’s humid microclimates near the coast, mold and mildew can colonize evaporator coils and duct interiors. We install UV lamps at the coil and in the return air stream for properties where moisture management is ongoing. For homes without existing ductwork, we integrate UV into the new ventilation design rather than treating it as an afterthought.
Humidifier & Dehumidifier Installation
Los Angeles’s climate varies dramatically by neighborhood. Coastal areas with persistent marine layer moisture need dehumidification support, while inland zones within the urban heat island run 10–15°F hotter and bone-dry during Santa Ana events. We assess your specific Los Angeles location before recommending humidification or dehumidification, and we size equipment for the actual conditions your home experiences, not city-wide averages.

Trusted Brands We Service in Los Angeles
We maintain factory-trained compatibility across nine major HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Los Angeles customers, this means we stock parts and replacement components locally rather than ordering from out of state and waiting a week. We see a lot of Trane and Lennox equipment in the newer Los Angeles condo stock, while Goodman and Rheem systems are common in retrofit installations for older buildings. Our technicians arrive with the right components, because Marcus Feldman still manages jobs in the field and knows what these neighborhoods actually run.
Common Air Quality & Ventilation Problems We See in Los Angeles Homes
- Salt-air corrosion of ventilation hardware. Coastal Los Angeles’s salt-laden air attacks galvanized ductwork, ERV cores, and fasteners years faster than inland climates. We specify stainless hardware and coated components for installations within five miles of the ocean.
- Zero existing duct infrastructure. In the 1920s–1950s bungalows and low-rise apartments across South Central and Pico-Union, we regularly find cast-iron floor furnaces or wall heaters as the only heat source, with no ducts at all. Full load calculation and duct design from scratch is standard procedure, not a special request.
- Santa Ana dust overwhelming filtration. Standard fiberglass filters clog in hours during wind events. Los Angeles homes near construction zones or major corridors need higher-capacity filtration with more frequent change intervals.
- Tenant education gaps in older rentals. Landlords deferred AC and ventilation installation for decades. When we finally install central systems, tenants who’ve never operated thermostats or changed filters need walkthroughs to prevent equipment damage and warranty voids.
Pricing for Air Quality & Ventilation in Los Angeles, CA
Whole-home ventilation installation in Los Angeles typically runs $2,800–$7,500 depending on whether your property has existing ductwork. ERV systems for homes requiring full duct design from scratch fall at the higher end, while simpler replacements in homes with infrastructure already in place cost less. UV air purifier add-ons range $600–$1,400. Humidifier and dehumidifier installations typically cost $450–$1,800 based on capacity and integration complexity.
Your final price depends on three Los Angeles-specific factors: the need for custom duct design in pre-war housing, the mandatory HERS rater verification that adds scheduling coordination and a third-party fee, and salt-air-resistant component upgrades for coastal properties. We provide itemized, upfront pricing before any work begins. Estimates are free. Call (844) 560-6978 to schedule.

FAQs — Air Quality & Ventilation in Los Angeles
California Title 24 regulations require a third-party HERS-certified rater to field-verify duct leakage and refrigerant charge on every permitted HVAC job before the permit can close. This mandatory step does not exist in neighboring Arizona or Nevada, and your contractor must schedule it as part of the project timeline. We coordinate HERS rater appointments for all our Los Angeles installations and build the verification into our project schedule. Call (844) 560-6978 for an exact quote — estimates are free.
A ductless or minimally ducted ERV system with corrosion-resistant components is typically the best fit for Pico-Union’s 1920s–1950s bungalows that lack existing duct infrastructure. We design the duct system from scratch, size it for the actual envelope leakage of older construction, and specify hardware rated for salt-air exposure. The Daikin ERV we installed on Elm Street in South Central is representative of this approach. Call (844) 560-6978 to discuss your specific bungalow — estimates are free.
Santa Ana winds blow fine dust, pollen, and particulates from desert and construction areas into Los Angeles homes, overwhelming standard 1-inch filters and degrading indoor air quality within hours. We recommend high-MERV filtration sized for these seasonal surges, paired with sealed duct systems that don’t draw attic or crawl space air. For homes with occupants sensitive to particulates, we add UV air purification. Call (844) 560-6978 for an assessment — estimates are free.
Coastal Los Angeles neighborhoods with persistent marine layer moisture typically need dehumidification support, while inland areas within the urban heat island experience bone-dry conditions during Santa Ana events and benefit from humidification. We assess your specific Los Angeles location, your home’s envelope tightness, and your family’s health needs before recommending either. Many older Los Angeles homes have such variable room-to-room conditions that we zone the solution. Call (844) 560-6978 for a customized recommendation — estimates are free.
Yes, we factory-train on both Carrier and Lennox ventilation equipment and stock common parts for Los Angeles customers. Carrier systems appear frequently in newer Los Angeles condo developments, while Lennox ventilation components are common in higher-end retrofits. Our multi-brand coverage means we won’t tell you “we don’t work on that” — your system, our specialty. Call (844) 560-6978 to schedule service — estimates are free.
