We’re Crestview Heating & Air California, and our crew makes the trip up from San Jose to Corte Madera regularly for jobs that other companies won’t touch — ERV retrofits in 1960s ranch homes with zero ductwork, salt-corroded ventilation hoods on bay-fill parcels, and humidity problems that standard inland solutions can’t solve. Call (844) 560-6978 for a free estimate.
Corte Madera’s not like San Jose. The marine layer sits heavier here. Salt air off the bay eats equipment faster. And most of the housing stock — those post-war ranches between US-101 and the hills — was never built for modern ventilation. We’ve spent nearly two decades figuring out what actually works in these conditions, not what the manual says should work.
Why Crestview Heating & Air California Is Corte Madera’s Preferred Air Quality & Ventilation Company
Our 4.8-star average across 250+ reviews didn’t come from easy jobs. It came from showing up to the hard ones — the Rancho Corte Madera home with a failed ERV core corroded through in five years, the 1962 ranch on Madera Boulevard where every “standard” ventilation quote involved tearing out plaster. Owner Marcus Feldman still manages our service calls personally, so when you book with Crestview, you’re getting ownership-level accountability, not a dispatcher reading from a script.
We know the difference between a hillside Mill Valley install and a bay-side Corte Madera job. The salt-laden air off the Ecological Reserve corridor, the reclaimed marshland west of 101, the chronic crawl-space moisture in those low-lying parcels — these aren’t footnotes to us. They’re the starting point for every system we design.
Response time to Corte Madera is typically same-week for standard installs, with emergency HVAC service available when systems fail outside normal hours. We’ve got parts relationships that let us source Trane, Lennox, and Rheem components without the multi-week delays that leave Corte Madera homeowners running portable dehumidifiers and hoping for the best.
Our Air Quality & Ventilation Services in Corte Madera
ERV & HRV Systems
This is where we do our most distinctive work in Corte Madera. Energy Recovery Ventilators and Heat Recovery Ventilators are the right tool for a mild marine climate — they bring in fresh air without throwing away the heating or cooling you’ve already paid for. But here’s the local catch: in Corte Madera’s bay-side neighborhoods west of US-101, especially near the Ecological Reserve, outdoor ERV/HRV vent hoods and intake grilles often get clogged with salt-spray deposits within 3–4 years. We’ve learned to spec stainless-steel mesh filters and corrosion-resistant hardware that inland contractors don’t even stock. A typical ERV/HRV installation in Corte Madera runs $3,500–$7,500 depending on whether we’re tying into existing duct chases or building from scratch.
Ventilation Installation
Most Corte Madera ranch homes from the 1950s through 1970s were built with wall furnaces and no central ductwork. That means “ventilation install” here usually means creating a duct system where none existed — or finding creative ways to move air without it. On a damp March morning in the bay-side Rancho Corte Madera neighborhood, we found a client’s 1990s wall furnace providing no fresh-air ventilation. The original passive roof vents had been sealed during a re-roof. We installed a Zehnder ComfoAir 200 ERV with a pre-filter upgrade for salt resistance, tied into the existing gravity duct chases, and gave them balanced ventilation without losing the mild marine air they love. Your system, our specialty — even when there’s no system to start with.
Air Filtration
Corte Madera’s chronic bay humidity means equipment that might last 15 years in Sacramento can show significant corrosion within 8–10 years on the bay-side streets. That degradation doesn’t just hit your condenser — it hits your filtration media, your filter housings, your whole air-handling strategy. We size filtration systems for the actual particle load in these homes: pollen from the Marin hillsides, salt spray residue, and the mold spores that thrive in damp crawl spaces. A full air filtration system installation in Corte Madera typically runs $3,500–$7,500.
UV Air Purifier Installation
UV-C purification targets the biological growth that standard filters can’t stop — mold, bacteria, viruses. In Corte Madera’s older homes with wall furnaces and no return-air ducting, we often find negative pressure pulling humid crawl air into living spaces. That moist, stagnant air is exactly what mold colonies need. A UV lamp mounted at the coil or in the supply plenum kills what’s living there before it circulates. We install UV systems as standalone units or integrated with new filtration — call (844) 560-6978 to discuss which approach fits your setup.
Humidifier & Dehumidifier Installation
Corte Madera’s position between the bay and the Marin hillsides channels cool, damp Pacific marine air across town nearly year-round. Summer highs stay in the low-to-mid 70s; winter nights rarely drop below 40°F. So heating loads are modest, mechanical cooling is almost never essential, and humidity control becomes the central air-quality battle. Whole-home dehumidifiers tied into existing or new ductwork pull moisture out before it reaches your walls, your insulation, your lungs. Humidifiers are less commonly needed here but matter for homes with tight envelopes and wood heat — we’ll assess your actual conditions, not sell you what we have in the warehouse.

Trusted Brands We Service in Corte Madera
We factory-train on nine major brands — Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard — so Corte Madera homeowners are never told “we don’t work on that.” For ventilation and air quality specifically, we lean on Trane’s CleanEffects filtration, Lennox’s PureAir systems, and Rheem’s integrated humidity controls. We stock common parts for these lines locally, which means faster turnaround when your ERV core fails in January or your dehumidifier compressor quits during a wet spring. From emergency calls to commercial buildouts, if it moves air in Corte Madera, we’ve probably serviced it.
Common Air Quality & Ventilation Problems We See in Corte Madera Homes
- Salt-corroded ERV/HRV cores. The bay-facing western neighborhoods built on reclaimed tidal marshland expose outdoor ventilation equipment to persistent salt-laden marine air. We routinely find heat-exchange cores degraded by 30% or more within 5–7 years — efficiency loss you can feel as stuffiness and higher energy bills.
- Undersized, blocked crawl-space vents. Original passive vents in ranch homes on bay-fill parcels are often too small and clogged with moisture debris. The result: mold on duct insulation, musty first-floor air, and a ventilation system that’s technically present but functionally useless.
- Negative pressure from wall furnaces. Homes with no return-air ducting create suction that pulls humid crawl air into living spaces. We’ve measured indoor humidity spikes of 15–20% above outdoor ambient in these conditions — a direct hit to air quality and occupant comfort.
- Sealed roof vents after re-roofs. Corte Madera’s older homes often had passive roof ventilation that contractors sealed during roofing work, not understanding the ventilation function. The homeowner ends up with a “tight” roof and stagnant indoor air — a problem that only shows up months later.
Pricing for Air Quality & Ventilation in Corte Madera, CA
Here’s what we charge for the work we do most often in Corte Madera. These ranges reflect actual jobs we’ve completed in the 94925 and 94976 ZIP codes — not national averages, not guesses.
| Service | Typical Range in Corte Madera |
|---|---|
| Tune-Up (ventilation system inspection, filter change, airflow test) | $80–$200 |
| Air Filtration System Installation (whole-home, with media cabinet) | $3,500–$7,500 |
| ERV/HRV System Installation (new, with basic duct tie-in) | $3,500–$7,500 |
| UV Air Purifier Installation (single-lamp, coil-mounted) | $800–$1,800 |
| Whole-Home Dehumidifier Installation | $2,200–$4,500 |
What moves the needle within these ranges? Ductwork complexity is the big one — a home with existing gravity chases costs less than one where we’re cutting new returns. Salt-resistant hardware upgrades add 10–15% but pay back in lifespan. And access matters: tight crawl spaces on those low-lying bay-fill parcels take more labor than hillside basements. We quote upfront, in writing, before any work starts. Call (844) 560-6978 for your free estimate.

FAQs — Air Quality & Ventilation in Corte Madera
Salt-laden bay air has likely degraded your heat-exchange core and clogged the intake grille with corrosion debris — a pattern we see constantly in bay-side Corte Madera homes, where equipment ages twice as fast as inland. The musty smell is mold and bacteria growing on the compromised surfaces. We can replace the core with a salt-resistant upgrade and install stainless-steel pre-filters that inland contractors don’t spec. Call (844) 560-6978 for an exact quote — estimates are free.
Yes. We regularly retrofit ERVs into Corte Madera’s 1950s–70s ranch homes by using existing gravity duct chases, closet runs, or slim duct systems designed for exactly this situation. The Zehnder ComfoAir line and similar compact units fit where traditional ductwork won’t. Marcus Feldman personally assesses each home to find the path of least intrusion. Call (844) 560-6978 to schedule a walkthrough.
Yes — the chronic humidity is exactly why you need one. Corte Madera’s marine layer keeps relative humidity high enough to promote mold growth inside walls and crawl spaces, even when outdoor conditions feel comfortable. A whole-home dehumidifier pulls moisture out at the source, before it reaches your living space or your insulation. We size these for your home’s actual envelope and crawl-space conditions, not a generic chart. Call (844) 560-6978 for a free assessment.
Your ventilation unit is absolutely at risk, especially if the outdoor hood faces the bay. We find corroded fasteners, pitted coil fins, and degraded wiring insulation on Corte Madera ventilation equipment only 7–10 years old — the same salt-air damage pattern, just less visible because the unit’s smaller and quieter than your condenser. If your condenser is showing salt damage, we recommend a full ventilation inspection with corrosion-resistant hardware upgrades. Call (844) 560-6978 to schedule.
Filtration captures particles; UV kills living organisms. In Corte Madera’s damp conditions, we find mold and bacteria colonizing coil surfaces and drain pans even in homes with excellent filters — the moisture is the enabler, and no MERV rating stops biological growth on wet metal. A UV lamp at the coil addresses what filtration can’t. We typically recommend both together for homes with chronic humidity or crawl-space moisture issues. Call (844) 560-6978 to discuss whether UV makes sense for your setup — estimates are free.
