Owner Marcus Feldman also serves as Service Manager, so ownership-level accountability is built into daily operations — not just the sales pitch. When you call Crestview, you’re not getting dispatched through a call center; you’re getting owner-managed service.
We know Lomita’s streets well. Whether we’re heading to a bungalow off Lomita Boulevard, a ranch home near Western Avenue, or a property closer to the Palos Verdes Peninsula border, we understand the local conditions that affect your indoor air. The marine layer, the salt-laden air from San Pedro Bay, the legacy heating systems — these aren’t abstract concepts to us. We factor them into every recommendation.
Our Air Quality & Ventilation Services in Lomita
ERV/HRV System Installation
Energy Recovery Ventilators (ERVs) and Heat Recovery Ventilators (HRVs) are the gold standard for bringing fresh outside air into your home without wasting the energy you’ve already spent heating or cooling. But here’s the Lomita reality: salt-laden marine air from San Pedro Bay, roughly 5 miles southwest, corrodes ERV/HRV heat-exchange cores within 3–5 years. That means reduced ventilation efficiency and musty odors creeping back in. We specify corrosion-resistant components and design for accessible maintenance because we’ve seen what the local air does to standard equipment. A typical ERV/HRV system installation in Lomita runs $3,500–$7,500, depending on whether your home has existing ductwork or needs a full retrofit.
Air Filtration
Lomita’s proximity to the Port of LA means fine particulate matter, diesel exhaust, and industrial pollutants ride inland on prevailing winds. Standard 1-inch fiberglass filters don’t cut it here. We size and install media air cleaners and electronic air filtration systems that actually match the particle load your home faces. For homes near the port or along major corridors like Pacific Coast Highway, we typically recommend MERV 13+ filtration or dedicated HEPA bypass systems. Your system, our specialty — we service 9 major brands including Trane, Lennox, Goodman, and Rheem, so we’ll match the right filtration to whatever equipment you have or plan to install.
Ventilation Install
This is where Lomita’s housing stock gets complicated. Many homes here have zero duct infrastructure — just a wall heater or gravity floor furnace with no plenum, no returns, nothing. First-time ventilation installation in these homes means designing ductwork from scratch, often in tight crawlspaces with limited clearance. We recently worked on a 1952 bungalow near Western Avenue and Lomita Boulevard where the client wanted to add central air but had a functioning floor furnace with asbestos-wrapped boots. We coordinated hazmat removal of the asbestos, then designed a ducted ventilation system with a Carrier UV air purifier to address the persistent marine-layer dampness that had been causing mold in the unventilated crawlspace. That’s the kind of project complexity you don’t find in newer Torrance subdivisions.
UV Air Purifier
UV-C light systems mounted inside your air handler or ductwork neutralize mold, bacteria, and viruses on the coil surface and in the airstream. In Lomita, where marine-layer dampness keeps indoor humidity elevated through much of the year, coil mold is a persistent issue. We’ve found UV air purifiers particularly effective for homes in the flatter areas near Lomita Boulevard, where morning overcast lingers longest and crawlspace moisture is toughest to control. Pair a UV system with proper ventilation, and you’re addressing both the source of contamination and the damp conditions that let it thrive.

Common Air Quality & Ventilation Problems We See in Lomita Homes
- Salt-corroded ERV/HRV cores. The marine air flowing inland from San Pedro Bay destroys standard aluminum heat exchangers in 3–5 years. We see this most often in homes within a mile of the water, where owners installed quality equipment but weren’t warned about local corrosion risk.
- Negative pressure from original floor furnaces. These legacy units exhaust combustion gases through a roof vent while pulling replacement air from cracks and gaps around windows, doors, and crawlspace vents. That uncontrolled infiltration overrides any air filtration system you’ve added, pulling in unfiltered outside air directly into your living space.
- Asbestos-wrapped supply boots disturbed during retrofit work. Technicians working the older streets near Western Avenue and Lomita Boulevard regularly find 1950s–60s floor furnaces still in active use with asbestos-wrapped supply boots. Disturbing these during ductwork installation triggers hazmat containment protocols, project delays, and added cost — something we plan for upfront, not discover mid-project.
- Mold in unventilated crawlspaces. The marine layer keeps relative humidity high, especially in homes without ground vapor barriers or adequate crawlspace ventilation. We’ve found active mold growth in crawlspaces that haven’t been inspected in decades, spreading spores upward through floor gaps.

What moves you within these ranges? Existing ductwork versus full retrofit, hazmat abatement needs, electrical panel capacity, and accessibility of your crawlspace or attic. Homes with original floor furnaces and no ducts land at the higher end — that’s just the reality of Lomita’s housing stock. We provide upfront, itemized quotes before any work begins.

FAQs — Air Quality & Ventilation in Lomita
Salt-laden marine air from San Pedro Bay corrodes standard aluminum heat-exchange cores within 3–5 years, versus 8–12 years in inland climates. We specify corrosion-resistant or coated cores for Lomita installations and build in accessible maintenance access so cores can be inspected and replaced before failure causes musty odors or energy waste. Call (844) 560-6978 if your ERV/HRV isn’t performing — we can diagnose core condition and recommend repair or upgrade.
Yes, but the asbestos must be properly abated first by a licensed hazmat contractor before we can design and install ductwork. We coordinate this sequence regularly in Lomita’s older neighborhoods and factor abatement timing into our project schedule so you’re not left without heat during the transition. We’ll assess your specific setup during our free estimate and walk you through the phased approach.
MERV 13+ pleated media filtration or a dedicated HEPA bypass system handles the fine particulates and diesel exhaust that drift inland from port operations. For homes closest to the water, we often pair this with activated carbon pre-filtration to address odor compounds. The right system depends on your existing HVAC infrastructure — homes with no ductwork may need a ducted mini split or ERV-based solution first.
Whole-house ventilation requires a distribution system, but that doesn’t have to be traditional ductwork. We can design a ducted mini split system with dedicated ventilation integration, or in some cases use high-velocity mini duct systems that fit within Lomita’s tight wall and floor cavities. The 90717 ZIP code is full of homes exactly like yours — we’ve solved this challenge many times. Your free estimate will include options matched to your budget and comfort goals.
The marine layer keeps summer mornings overcast and maintains higher baseline humidity than inland LA County, especially June through August. Without mechanical ventilation and dehumidification, that moisture accumulates in crawlspaces and wall cavities, supporting mold growth and musty odors. We’ve found that homes without dedicated ventilation systems in Lomita consistently run 10–15% higher indoor relative humidity than similar homes in Torrance’s eastern tracts, which sit further from the bay’s influence.
