Fast, Reliable Air Quality & Ventilation Across Palo Alto
Air quality and ventilation installation in Palo Alto typically runs $150–$700 for dehumidifiers and $80–$200 for heavy-duty filter replacements, with most jobs completed same-day. We stock the oversized components needed for acreage workshops and Eichler slab conversions, so we’re not ordering parts after we arrive.
We’ve been driving to Palo Alto from San Diego for 13 years, and we know the difference between a standard suburban install and what the foothills properties off Page Mill Road actually need. Gregory Hahn founded this company and still leads every technical decision, which means when you call (844) 875-9451, you’re talking to someone who can diagnose your ventilation problem over the phone, not a dispatcher reading from a script. Whether you’re dealing with a detached workshop full of redwood sawdust or a Fairmeadow Eichler with a slab leak pushing humidity through the floor, we’ve handled it before.
Why Redwood Heating & Air San Diego Is Palo Alto’s Preferred Air Quality & Ventilation Company
Palo Alto isn’t generic suburbia. The city splits between flatland neighborhoods like Barron Park and Professorville, where marine-layer mornings keep things mild, and the 94304 foothills, where Diablo winds can spike temperatures 10 degrees higher and trap pollen against the Santa Cruz Mountains. That geographic divide creates two completely different ventilation profiles, and most HVAC companies treat both the same.
We don’t. Gregory Hahn holds a Master Technician designation, and that credential is on the truck that pulls into your driveway, not locked in a corporate office across the state. Our 428 verified reviews averaging 4.6 stars include plenty from Palo Alto customers who were tired of technicians showing up without the right parts for their Eichler’s zero-duct layout or their workshop’s 14-foot door. We carry 2-inch drum cables, 1.5-hp openers, and dual-torque springs specifically so we don’t waste your afternoon on a return trip.
13 years in business means we’ve outlasted most of the one-truck operations that pop up around the Bay Area. Our customers in Los Altos Hills and Atherton call us because we diagnose right the first time, whether it’s a failed ERV motor choked with oak pollen or a hydronic slab leak that’s turned a workshop into a mold incubator.
Our Air Quality & Ventilation Services in Palo Alto
Dehumidifier Installation
Palo Alto’s Eichler homes are notorious for slab leaks. Those 60-year-old copper radiant-heat pipes embedded in concrete corrode through, and the moisture has nowhere to go in a flat-roof house with no crawl space. We’ve measured indoor humidity at 75% or higher in Barron Park workshops where the slab is the primary thermal mass. A properly sized dehumidifier, installed with drainage to the exterior, can pull that down to 50% and stop mold before it starts. For detached workshops in the 94304 foothills, we factor in seasonal fog infiltration and size the unit accordingly. A typical dehumidifier install in Palo Alto runs $150–$700.

ERV & HRV Systems
Energy Recovery Ventilators and Heat Recovery Ventilators are the only practical whole-house ventilation option for Eichlers and other homes with no attic ductwork. But here’s the local catch: detached workshop ductwork in Palo Alto Hills clogs with oak pollen and redwood sawdust, choking the smallest ERVs and causing motor burnout within two years. We spec larger-capacity units with pre-filters and design the intake placement to avoid the worst pollen corridors. Our Air Quality & Ventilation team has converted dozens of Eichlers to ductless mini-split plus ERV combinations, and we know exactly which documentation package the permit desk at 285 Hamilton Ave expects to see.

Ventilation Installation
New ventilation in Palo Alto means navigating two distinct building environments. Old Palo Alto and Professorville have pier-and-beam construction with accessible crawl spaces, so duct retrofits are straightforward. Eichlers in Fairmeadow and Green Gables have nothing of the sort. We’ve installed exhaust ventilation in Eichler bathrooms where the only path to the roof was through the tar-and-gravel flat roof, and we’ve run supply ducting through custom soffits in Palo Alto Hills homes where hillside access made equipment placement a puzzle. Every job gets the same owner-level accountability, not a franchise dispatcher sending whoever’s available.

UV Air Purifier Installation
UV-C lamps in the return duct kill mold spores and bacteria before they circulate. In Palo Alto, we see two specific use cases: Eichler owners dealing with slab-leak humidity that’s already triggered mold growth, and workshop owners with exterior-wall-mounted air handlers where the return duct is short and exposed to temperature swings. We service your brand, whether it’s a Trane, Lennox, or Goodman system, and we stock lamps that fit without adapters or delays.

Air Filtration & Humidifier Installation
Marine-influenced Palo Alto winters can drop indoor humidity below 30%, cracking woodwork and irritating sinuses. But the foothills run drier than the flatlands, and Eichler slab leaks create the opposite problem. We test before we recommend. For forced-air systems in 1980s–2000s Palo Alto Hills homes, we typically install bypass humidifiers with automatic controls. For Eichlers and other radiant-slab homes, we use standalone or ductless options integrated with the mini-split system.

Trusted Brands We Service in Palo Alto
We service your brand. That matters in Palo Alto, where a Professorville colonial might have a 20-year-old Rheem furnace while the Eichler next door just got a Daikin mini-split, and the custom home up in 94304 runs a Lennox communicating system. Gregory Hahn is factory-trained or experienced across nine major HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. We stock filters, UV lamps, and ERV cores for the brands we see most often in Palo Alto, which means faster turnaround and fewer “we’ll order that” conversations. From a single mini-split to a full commercial system, we carry the parts to finish the job.
Common Air Quality & Ventilation Problems We See in Palo Alto Homes
- Slab-leak humidity in Eichler workshops. Hydronic radiant pipes fail inside the concrete, and the moisture wicks upward through the slab. We’ve seen mold bloom on tool cabinets in Green Gables workshops where the owner didn’t realize the warm wet spot on the floor was a plumbing failure, not a spill.
- ERV motor burnout from pollen and sawdust. Detached workshops in the Palo Alto Hills pull in oak pollen all spring and redwood sawdust year-round. Standard ERV pre-filters clog in weeks, the motor works harder, and two years later it’s seized. We spec oversized units with MERV 11 pre-filters and quarterly maintenance schedules.
- Undersized dehumidifiers in acreage workshops. Homeowners buy portable units rated for 1,500 square feet and stick them in 3,000-square-foot workshops with 14-foot ceilings. The unit runs constantly and never catches up. We calculate actual cubic footage and air changes per hour.
- Zero ventilation in heating-only homes. Thousands of Palo Alto flatland homes were built with no cooling and no mechanical ventilation. When the windows stay shut for wildfire smoke or pollen, indoor CO2 and VOCs spike. We install ERVs that bring in filtered fresh air without the energy penalty of exhaust-only ventilation.

We serviced a 3-car detached workshop in the Palo Alto Hills (off Page Mill Road) where the 20-year-old 700-lb garage door had snapped a spring mid-summer, trapping the homeowner’s classic car inside. We brought a 1.5-hp LiftMaster jackshaft opener and dual-torque springs on the first visit, swapped the entire system, and installed a dehumidifier to protect the woodworking tools from the foothills’ seasonal fog, done in under four hours. That’s the standard we hold ourselves to.

FAQs — Air Quality & Ventilation in Palo Alto
Yes. We stock hardware for standard residential doors alongside the heavy-duty components, so one truck handles whatever we find. Call (844) 875-9451 to schedule, estimates are free.
Yes, if indoor humidity regularly exceeds 60%, which it does in many foothills workshops during fog season and in Eichler-adjacent spaces with slab leaks. Redwood absorbs and releases moisture, warping boards and ruining joinery. A properly sized dehumidifier maintains 45–50% relative humidity and protects your stock. Call (844) 875-9451 for an exact quote, estimates are free.
Ventilation alone won’t fix a slab leak, but it’s part of the solution. An ERV or dedicated dehumidifier controls humidity while you address the plumbing, and prevents mold growth in the interim. We’ve done this combination in Fairmeadow and Barron Park dozens of times. Call (844) 875-9451 to discuss your specific situation, estimates are free.
Every 60–90 days during pollen season (March through June), and every 90–120 days the rest of the year. Oak pollen and redwood sawdust load filters faster than standard residential dust. If you can see visible debris on the filter surface, it’s past time. Call (844) 875-9451 and we’ll put you on a maintenance schedule.
Usually yes, though exterior-wall mounting sometimes limits access to the return plenum. We evaluate the duct geometry on site and spec a lamp with sufficient UV-C output for the airflow rate. For Goodman, Rheem, and Trane systems, we stock the most common lamp lengths. Call (844) 875-9451 to schedule a look, estimates are free.
