Alameda’s island position creates a one-two punch: salt-laden marine air attacks metal components from the outside, while pre-1940 homes with balloon-frame construction trap moisture inside walls. We’ve spent nearly two decades solving both problems. Owner Marcus Feldman still manages jobs in the field, so the person quoting your ERV install or dehumidifier placement is the same person ensuring it’s done right.

Why Crestview Heating & Air California Is Alameda’s Preferred Air Quality & Ventilation Company

Our 4.8-star average across 250+ customer reviews includes plenty of Alameda homeowners who found us after mainland companies couldn’t explain why their ductwork kept failing. They’d replaced systems twice in Oakland that lasted fifteen years, only to watch the same hardware corrode in seven on Alameda’s waterfront blocks.

We know the difference. That difference is salt air, and it changes everything about how you spec, install, and maintain ventilation equipment here.

Marcus Feldman serves as both Owner and Service Manager. No dispatch center. No rotating cast of subcontractors. When you call (844) 560-6978, you’re talking to someone with 19 years of HVAC experience who’ll personally make sure your Alameda job accounts for coastal corrosion from day one.

We service nine major brands — Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard — so your existing equipment is never a dead end. Your system, our specialty.

Our Air Quality & Ventilation Services in Alameda

ERV & HRV System Installation

Energy Recovery Ventilators and Heat Recovery Ventilators are the workhorses for Alameda’s tight, old homes. They exchange stale indoor air for fresh outdoor air without wasting the energy you’ve already paid to heat or cool. In a city where summer highs barely touch the low 70s but humidity lingers year-round, an ERV pre-conditions incoming air so your heating system doesn’t work overtime.

We recently replaced a corroded duct system in a 1900s Victorian on Pacific Avenue near the estuary; the salt air had rusted through all cross-joint fasteners and rotted the fiberboard lining, causing a 2-inch diameter leak in the supply trunk. We installed an ERV with stainless steel dampers and sealed the new galvanized duct joints with a mastic approved for coastal environments. That homeowner’s system efficiency jumped 30%.

For Alameda Point properties near the old Naval Air Station, we spec ERVs with marine-grade enclosures. The 1940s military housing and converted industrial structures out there face the same salt exposure as waterfront Victorians, often with worse original ventilation.

Ventilation Install

Adding whole-house ventilation to Alameda’s pre-1940 housing stock is rarely straightforward. These homes weren’t built with duct chases. Balloon-frame walls and original plaster ceilings aren’t forgiving to invasive retrofit work.

Our approach: mini-duct systems, high-velocity air handlers, and strategic routing through closets, basement joist bays, and minimal soffit drops. We preserve what makes your Alameda home distinctive. On Grand Street and throughout the Gold Coast, we’ve threaded supply lines through existing chase walls and used return plenums in crawl spaces to avoid tearing out lath-and-plaster.

A typical ventilation install in Alameda runs $3,500–$7,500, depending on whether we’re working with existing ductwork or starting from zero.

Dehumidifier Install

Yes, you need a dehumidifier in Alameda. The marine layer keeps relative humidity elevated even when temperatures stay mild. We’ve measured 65–70% indoor humidity in Alameda homes during July — not from poor ventilation, but from the Bay itself breathing moisture through every crack.

That persistent humidity promotes mold growth inside uninsulated or deteriorating ductwork, especially in balloon-framed homes where wall cavities become condensation traps. A whole-house dehumidifier integrated with your HVAC system keeps indoor relative humidity at 45–50%, stopping mold before it starts.

A dehumidifier install in Alameda typically runs $150–$700 for whole-house units, with smaller portable solutions at the lower end and integrated ducted systems at the higher.

UV Air Purifier & Air Filtration

UV-C air purifiers neutralize mold spores, bacteria, and viruses circulating through your ductwork. In Alameda’s older homes, where decades of moisture may have established colonies in wall cavities and crawl spaces, UV adds a critical layer of protection.

But here’s the local catch: salt air corrodes electrical terminals and damper actuators in air purifiers and UV systems, leading to early component failure on waterfront blocks. We spec units with sealed electronic compartments and coated circuit boards. The upfront cost is 15–20% higher. The replacement cycle stretches from 5 years to 12.

Media air filtration — MERV 13+ pleated filters — pairs well with UV in Alameda’s tight homes, capturing the pollen and particulate that gets trapped when you keep windows closed against the damp.

Trusted Brands We Service in Alameda

We stock parts and complete systems from Trane, Lennox, Goodman, and Rheem — four brands with proven coastal-compatible lines. Trane’s Spine Fin condenser coils hold up better against salt corrosion than standard plate-fin designs. Lennox’s Healthy Climate solutions include ERVs with stainless hardware options. Goodman and Rheem offer solid value for Alameda landlords and commercial property managers at Alameda Point who need reliable ventilation without premium pricing.

Because we carry inventory for nine major brands total, Alameda customers don’t wait for special orders. Most repairs complete same-day. Most installs start within a week of your call.

Common Air Quality & Ventilation Problems We See in Alameda Homes

• Salt-corroded duct fasteners failing in 5–7 years. Sheet metal screws and duct connectors on waterfront blocks rust through faster than inland. We find supply trunks leaking 15–20% of conditioned air into attics and crawl spaces. The fix: galvanized or stainless hardware with coastal-grade mastic seals.
• Mold in uninsulated ductwork of pre-1940 balloon-frame homes. Cold supply lines running through warm, humid wall cavities sweat. Over years, fiberboard duct liner rots. We replace with insulated flex or hard pipe, and add vapor barriers where the original construction never did.
• Corroded UV and air purifier electronics on estuary-facing properties. Pacific Avenue, Shore Line Drive, any block with a water view — we’ve replaced control boards that failed in 3 years instead of 10. We now spec epoxy-coated components and recommend annual electrical inspections.
• Zero ventilation infrastructure in converted Alameda Point military housing. The 1940s structures relied on operable windows and gravity airflow. Modern code demands mechanical ventilation. We design ERV-based solutions that don’t compromise the building’s historic character or structural integrity.
