Fast, Reliable Air Quality & Ventilation Across San Diego
Whole-house ventilation and air filtration in San Diego typically runs $175–$825 for standard installs, with ERV/HRV systems ranging $4,130–$8,850 depending on your home’s existing ductwork and layout. Most San Diego homeowners with 1950s–70s tract homes in Clairemont, Mira Mesa, or Allied Gardens face a unique challenge: these houses were built without any ductwork at all, making ventilation retrofitting a specialized job that demands local experience with tight attic spaces and creative routing. We’re Redwood Heating & Air, and we’ve spent 13 years solving exactly these problems across San Diego’s distinct microclimates, from the salt-air corrosion zones near Pacific Beach to the inland heat pockets of El Cajon.

Why Redwood Heating & Air San Diego Is San Diego’s Preferred Air Quality & Ventilation Company
Gregory Hahn founded this company and still leads every technical decision. That matters in San Diego, where a ventilation install in a 1962 slab-on-grade home in Mira Mesa requires completely different problem-solving than a coastal retrofit in Coronado with salt-air corrosion concerns. Our Air Quality & Ventilation team doesn’t dispatch interchangeable crews; Gregory’s Master Technician credential is on the truck, and his 13 years of field experience across nine major HVAC brands means we diagnose right the first time.
Our reputation here is concrete: 428 verified customer reviews averaging 4.6 stars, built continuously since we opened. San Diego customers mention our responsiveness specifically, and we maintain emergency HVAC service for urgent residential and commercial breakdowns across the metro. We service your brand, whether that’s a Bryant air handler, an American Standard ventilator, or a Carrier heat pump system we’re tying into new ventilation equipment.
From a single mini-split to a full commercial system, we handle the full spectrum. That includes the technically demanding work of retrofitting fresh air systems into homes that were never designed for them, a significant share of our San Diego market.
Our Air Quality & Ventilation Services in San Diego
Air Filtration
San Diego’s fall wildfire season pushes particulate levels high enough that standard 1-inch fiberglass filters fail completely. Whole-house MERV-13 filtration is the baseline we recommend, but here’s the local reality: many San Diego homes, especially the post-WWII stucco tracts in Clairemont and Lemon Grove, lack the ductwork to support a media cabinet install. We’ve solved this by pairing standalone air purifiers with ductless mini-split retrofits, or by running dedicated low-voltage ductwork through closets and soffits. A typical air filtration system installation in San Diego runs $175–$765.

Humidifier & Dehumidifier Installation
San Diego’s coastal marine layer keeps outdoor humidity moderate, but indoor conditions vary sharply by location and construction era. Homes in Ocean Beach or Point Loma often fight persistent dampness during June Gloom, while inland properties near Santee can drop below 30% RH in Santa Ana wind events. We install both whole-house humidifiers tied to existing forced-air systems and standalone dehumidifiers for homes without ductwork. The key is matching equipment to your actual conditions, not a regional average that doesn’t exist in this microclimate-split market.

UV Air Purifier Installation
UV-C lamp installations target biological growth on HVAC coils, a real concern in San Diego where many systems run near-continuous during warm months and coil condensation creates ideal conditions for mold. We specify lamp intensity and placement based on your specific coil geometry and airflow, not generic kit installations. This is particularly relevant for coastal San Diego homes where salt-air corrosion already stresses system components and any additional biological load accelerates deterioration.

ERV/HRV System Installation
This is where San Diego’s housing stock creates genuine technical complexity. Energy Recovery Ventilators and Heat Recovery Ventilators exchange stale indoor air for fresh outdoor air while recovering thermal energy, but they require ductwork to distribute that fresh air throughout the home. In a 1950s–70s slab-on-grade tract home with no basement and a cramped attic, that ductwork simply doesn’t exist.
We recently installed a Lennox HRV in a 1963 slab-on-grade tract home in Allied Gardens that had zero ductwork and only a floor furnace. The homeowner was concerned about stale air and high indoor humidity during June Gloom. Our crew ran new flex duct through a cramped attic crawl space and tied the HRV into a newly retrofitted Carrier heat pump system, giving the family fresh filtered air without the mustiness common in these mid-century homes.
Typical ERV/HRV system installation in San Diego runs $4,130–$8,850, with the wide range reflecting whether we’re integrating with existing ductwork or building distribution from scratch.

Ventilation Install
Standalone ventilation installs, bathroom exhaust upgrades, and kitchen range hood venting fall here. In San Diego’s older housing stock, we frequently find original exhaust fans that vent into attic spaces rather than outdoors, a code violation and moisture risk. Proper ventilation install in these homes often requires cutting new roof or wall penetrations and running insulated duct through tight spaces. Standard ventilation install work in San Diego runs $175–$825.

Trusted Brands We Service in San Diego
We maintain technical fluency across nine major HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For San Diego customers, this means we stock common parts locally and don’t need to special-order components for a Bryant ventilator or American Standard ERV while your indoor air quality suffers through a delay. Gregory Hahn’s Master Technician designation covers factory training and field experience across all nine lines, so we diagnose brand-specific control sequences and integration requirements accurately. In a market where many contractors push a single brand they’re dealer-incentivized to sell, our brand-agnostic approach means the right equipment for your San Diego home’s specific conditions, not the convenient warehouse stock.
Common Air Quality & Ventilation Problems We See in San Diego Homes
- Salt-air corrosion destroys coastal ventilation equipment. Outdoor air intake louvers and ventilator housings installed within a mile of the coast, in Pacific Beach, Ocean Beach, or Coronado, show significant deterioration in 5–7 years. Standard manufacturer warranties don’t account for this. We specify coated coils or stainless components as baseline recommendations, not upsells.
- Plug-in filters fail during wildfire events. San Diego’s elevated fall particulate loads from regional wildfires overwhelm the small filters in ductless mini-splits and standalone room units. Whole-house MERV-13 filtration handles the load, but requires ductwork that many older San Diego homes lack.
- Slab-on-grade homes trap stale air. Without basements and with limited attic clearance, 1950s–70s tract homes in Mira Mesa, Clairemont, and Allied Gardens have no natural air exchange pathways. Floor furnaces and wall heaters don’t move air; occupants report stuffiness even with windows open, especially during June Gloom when outdoor humidity suppresses natural ventilation incentives.
- Poor ERV/HRV airflow distribution from compromised placement. When ductwork has to be routed through closets or soffits due to tight attic spaces, airflow balancing becomes critical. Installations without careful local design experience often result in fresh air reaching only the rooms nearest the unit, leaving bedrooms and distant spaces unchanged.
Pricing for Air Quality & Ventilation in San Diego, CA
San Diego’s housing diversity, coastal-to-inland climate split, and aging housing stock make ventilation pricing more variable than in markets with uniform new construction. Here’s what we actually charge:
| Service | Typical Range in San Diego |
|---|---|
| Air Filtration System Installation | $175–$765 |
| Ventilation Install | $175–$825 |
| ERV/HRV System Install | $4,130–$8,850 |
What moves you within these ranges: existing ductwork versus new routing, coastal corrosion protection specifications, electrical panel capacity for new equipment, and whether we’re integrating with an existing HVAC system or installing standalone. Homes in Coronado or La Jolla near the coast typically land higher due to stainless component requirements. Slab-on-grade retrofits in Clairemont or Allied Gardens with no existing ductwork trend toward the upper ERV/HRV range due to labor-intensive routing work.
We provide upfront pricing after inspection, not ballpark guesses that change on-site. Estimates are free. Call (844) 875-9451 to schedule.

FAQs — Air Quality & Ventilation in San Diego
San Diego’s mild temperatures often don’t create enough natural stack effect to move air through a home, especially in single-story slab-on-grade construction with limited ceiling height. During June Gloom, outdoor humidity can exceed indoor levels, so open windows actually introduce moisture rather than relief. A whole-house ventilation system with mechanical exhaust and fresh air intake solves this by creating controlled air exchange regardless of outdoor conditions. Call (844) 875-9451 for an exact quote on your home’s layout.
Yes, but it requires creative routing through tight attic spaces, closets, or soffits since there’s no basement and no existing ductwork. We’ve completed dozens of these retrofits in Clairemont, Mira Mesa, and Allied Gardens. The key is careful load calculation and airflow balancing to ensure fresh air reaches all rooms, not just the spaces nearest the unit. Typical ERV/HRV install in these homes runs $4,130–$8,850 depending on routing complexity. Call for a free inspection of your specific floor plan.
Yes. Homes within a mile of the coast in Pacific Beach, Ocean Beach, Coronado, or La Jolla experience salt-air corrosion that destroys standard outdoor air intake louvers and ventilator housings in 5–7 years. We specify coated coils, stainless steel components, and enhanced cabinet protection as standard practice for coastal San Diego installs, not optional add-ons. This extends equipment life significantly beyond manufacturer baseline assumptions. Call (844) 875-9451 to discuss coastal specifications for your property.
MERV-13 is the minimum effective rating for wildfire particulate, which includes PM2.5 particles that penetrate standard fiberglass filters. However, many San Diego homes, especially 1950s–70s tract houses, lack the ductwork to support a whole-house media cabinet. In those cases, we design standalone HEPA air purifiers or pair filtration with ductless mini-split retrofits that include dedicated air handling. The “best” filter depends on your home’s existing infrastructure, not a universal recommendation. Call for an assessment of your specific system.
Yes. Floor furnaces don’t move air through ducts, so they don’t preclude adding a ventilation system, but they also don’t help distribute it. We typically tie new ventilation equipment into a complementary heating upgrade, such as a ducted heat pump or mini-split system, which California’s Title 24 code increasingly favors anyway. In a recent Allied Gardens project, we ran new flex duct through a cramped attic and integrated an HRV with a Carrier heat pump retrofit, replacing both the floor furnace and the stale-air problem.
