Fast, Reliable Air Quality & Ventilation Across Inglewood
Air quality and ventilation work in Inglewood typically runs $1,200–$4,800 depending on whether you’re adding filtration to an existing system or installing a full ERV in a sound-insulated home. Most Inglewood homeowners see us within a day of calling, and we carry parts for the nine major brands so we’re not ordering and waiting. If your home was retrofitted through the LAX sound insulation program and that ventilation fan just died, call us at (844) 560-6978 — we know those systems, we know who actually owns them now, and we’ll give you straight answers.
We’ve been driving to Inglewood from San Jose for years, and the jobs here are different. The ZIP codes we cover — 90306, 90307, 90308, 90309 — sit under some of the busiest flight paths in the country, and that shaped your house whether you realize it or not. The marine layer keeps summers mild, but it also keeps humidity hanging around. Your ventilation system has to handle both.

Our Air Quality & Ventilation Services in Inglewood
ERV & HRV Systems
Energy Recovery Ventilators and Heat Recovery Ventilators are the right solution for Inglewood’s sound-insulated homes. The LASP program tightened thousands of building envelopes with new windows, doors, and insulation — great for noise, but it traps stale air, cooking odors, and CO2. An ERV brings in fresh air while transferring heat and moisture, so you’re not dumping conditioned air outside.
In a Morningside Park 1920s bungalow, we found the LASP-installed attic fan had failed, leaving the home stale. We installed a Lennox ERV sized per the sealed envelope, ensuring fresh air without compromising the soundproofing. Typical ERV installation in Inglewood runs $2,800–$4,800, including duct modifications for the sealed envelope.

Ventilation Installation
New ventilation for Inglewood homes means accounting for that marine layer humidity and whether your house was soundproofed. Unmodified 1940s–1960s homes usually need duct sealing and insulation before any ventilation upgrade — those original metal ducts run through 140°F attics and leak 20–30% of airflow. For LASP homes, we calculate lower infiltration rates and spec smaller, more efficient equipment. Basic ventilation install starts around $1,200; full duct overhaul with new ventilation runs $3,200–$5,500.

Air Filtration
Inglewood’s proximity to LAX means jet particulates, and the marine layer traps local pollution close to ground level. A whole-home media filter or electronic air cleaner captures what your 1-inch disposable misses. For LASP-retrofit homes with minimal natural leakage, filtration becomes even more critical — you’re not getting the air changes you used to. Media filtration add-on: $450–$950 installed. Electronic air cleaner: $1,100–$1,800.

UV Air Purifier
UV-C lamps mounted at the evaporator coil prevent mold growth, and in Inglewood’s humid coastal climate, that’s a genuine concern. We’ve seen coils in oversized LASP systems caked with mold because the unit short-cycles and never runs long enough to dry properly. A UV lamp kills the biology before it spreads through your ducts. Installation: $650–$1,100.

Humidifier & Dehumidifier Installation
Inglewood rarely needs humidification — the marine layer provides plenty. Dehumidification is the real need, especially in sound-insulated homes where natural drying doesn’t occur. Whole-home dehumidifiers tied to your central system run $1,800–$3,200. We typically pair these with ERVs in LASP homes to manage moisture without overcooling.

Trusted Brands We Service in Inglewood
We service and stock parts for Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard — your system, our specialty. For Inglewood’s ventilation work, we frequently install Lennox ERVs and Rheem media filtration because they’re proven in coastal humidity and fit the tighter duct configurations common in retrofitted homes. We don’t tell you “we don’t work on that.” If it’s heating, cooling, or moving air in your building, we’ve seen it and we carry the parts.
Common Air Quality & Ventilation Problems We See in Inglewood Homes
- LASP ventilation units failing at 15–20 years. The sound insulation program installed mechanical ventilation or A/C in thousands of homes starting in the early 2000s. That equipment is now hitting end-of-life, and many homeowners don’t realize the FAA-funded warranty expired years ago. They own it now, and we’re the ones who have to break that news — then fix it properly.
- Oversized A/C in soundproofed homes short-cycling and growing mold. The tightened envelope drops the cooling load, but original equipment was often sized for the old leakage rate. The result: a system that blasts cold air for eight minutes, shuts off, and never runs long enough to pull humidity out. We see this in Inglewood’s 90308 ZIP especially, where the marine layer keeps relative humidity above 60% even on mild days.
- Original ductwork in unmodified post-war homes leaking into hot attics. Those 1940s–1960s single-family homes and duplexes have galvanized ducts that have separated at seams or lost insulation. Your ventilation system can’t move air that never reaches the rooms. We test with a duct blaster and show you the numbers before we quote sealing or replacement.
- Homeowners confusing sound insulation warranty with HVAC warranty. This happens constantly in Inglewood. LAWA covered the installation and maybe 10 years of service. After that, it’s your equipment, your maintenance, your replacement cost. We explain this clearly because nobody else did.

What moves you within these ranges: whether your home was soundproofed (tighter envelope = more complex load calc and smaller equipment), accessibility to attic ductwork, and whether we need to upsize electrical for new ventilation. LASP homes often need dedicated low-voltage wiring for ERV controls that wasn’t run originally.
We don’t guess. We measure airflow, test duct leakage, and calculate your actual ventilation requirement per ASHRAE 62.2 — adjusted for Inglewood’s sealed envelopes when applicable. Estimates are free. Call (844) 560-6978 to schedule.

FAQs — Air Quality & Ventilation in Inglewood
No. The LASP warranty period expired years ago for most installations, and the equipment is now your financial responsibility. Many Inglewood homeowners first learn this when a fan or ventilator fails and they call LAWA, who direct them to private HVAC contractors. We handle these calls regularly and can assess whether repair or replacement makes sense for your sealed envelope. Call (844) 560-6978 for a free evaluation.
Yes. The persistent coastal humidity means an ERV alone may not keep indoor relative humidity below 60% in a tightly sealed home. We often recommend pairing an ERV with a whole-home dehumidifier in LASP-retrofit properties, particularly those without central A/C that would otherwise provide some dehumidification. The mild temperatures mean you won’t run cooling enough to dry the air naturally.
Yes. We frequently install ductless ventilation solutions in Inglewood’s older housing stock, including through-wall ERVs and point-source exhaust systems with makeup air. For homes without attics or with finished ceilings, we route flexible duct through closets, crawl spaces, or exterior wall chases. We’ll show you the path during your free estimate.
We install Lennox and Rheem UV-C systems most often in Inglewood because both are proven in high-humidity coastal environments and have readily available replacement lamps. The key isn’t the brand so much as proper placement at the evaporator coil and correct intensity for your system size. We size and install based on your specific coil dimensions and airflow, not generic recommendations.
Yes, and you may need to. The tighter envelope reduces infiltration of outdoor pollutants, but it also traps indoor-generated particles — cooking, cleaning chemicals, offgassing — and reduces natural air changes. A whole-home media filter or electronic air cleaner becomes more important, not less, because you’re relying entirely on mechanical ventilation for fresh air. We assess your new infiltration rate and recommend filtration matched to the sealed envelope.
