Fast, Reliable Air Quality & Ventilation Across Loomis
Air quality and ventilation in Loomis homes demands a different playbook than the tract-house fixes that work in Roseville. We’re Redwood Heating & Air San Diego, and our Air Quality & Ventilation crew makes the run up I-80 to Loomis regularly — usually same-day when indoor air problems can’t wait. Gregory Hahn founded this company and still leads every technical decision, and over 13 years we’ve learned that Loomis’s custom-built homes, propane-heated rural parcels, and wildfire-exposed foothill location create air-quality challenges you simply won’t find in denser suburbs.

Why Redwood Heating & Air San Diego Is Loomis’s Preferred Air Quality & Ventilation Company
Our reputation in Loomis has been built one custom home at a time. The 428 verified reviews averaging 4.6 stars include plenty from homeowners off Taylor Road, Horseshoe Bar Road, and the ranchette properties near the Placer County border — people who needed more than a filter swap and got master-technician diagnosis instead.
Response time matters when wildfire smoke is pouring through your ducts or your propane furnace is creating negative pressure that’s pulling garage fumes inside. We’re typically on-site in Loomis within hours, not days, because we keep common filtration and ventilation components stocked for the brands we service.
Gregory Hahn holds a Master Technician designation, and that credential is on the truck that rolls up your driveway — not locked in a corporate office three counties away. From a single mini-split to a full commercial system, we diagnose right the first time because we’ve spent 13 years across nine major HVAC brands, not one.
Our Air Quality & Ventilation Services in Loomis
Air Filtration
Loomis sits in the I-80 Sierra corridor, and every fire season that geography becomes a problem. The corridor funnels wildfire smoke from the surrounding mountains directly through the area, making media filtration a consistent customer concern, not a luxury upgrade. We size and install MERV 13 and higher filtration systems matched to your existing equipment — critical for the 1970s-through-2000s custom homes that dominate Loomis, where oversized floor plans and vaulted ceilings demand real airflow calculations, not guesswork. A typical MERV 13 filter upgrade in Loomis runs $80–$200; full air filtration system installation ranges $3,500–$7,500.

Ventilation Install
Here’s the reality that separates Loomis from Roseville: many rural homes on propane lack the robust whole-house ventilation that modern all-electric ducted heat pumps provide, leading to stale indoor air and higher particulate levels, especially during wildfire season. We design and install fresh-air ventilation systems that work with your existing heating setup — whether that’s propane, electric resistance, or a heat pump — bringing in filtered outside air without destroying your energy efficiency. For homes on large lots with frequent vaulted or exposed-beam ceilings, every duct run gets calculated individually.

ERV/HRV System
Energy Recovery Ventilators and Heat Recovery Ventilators are the right tool for Loomis’s hard-freeze winters and 100°F+ summers. These systems exchange stale indoor air for fresh outdoor air while recovering heating or cooling energy — critical when your HVAC system is fighting a 70-degree seasonal swing that Sacramento barely sees. ERV/HRV installation in Loomis typically runs $3,500–$7,500, with ERVs preferred for summer humidity control and HRVs for drier winter operation.

Humidifier Install
Loomis’s Sierra foothill winters deliver genuine hard freezes, and the cold air that comes with them holds almost no moisture. We install whole-house humidifiers integrated with your central system, sized for the large floor plans common off Sierra College Boulevard and the custom homes near the Loomis Basin. Proper humidity levels protect woodwork, reduce static, and make your home feel warmer at lower thermostat settings.

Dehumidifier Install
We serviced a 1970s custom home on Horseshoe Bar Road where the aging, unsealed ductwork in an unconditioned crawlspace was pulling in dust and smoke. Our crew installed an AprilAire whole-house dehumidifier with MERV 13 filtration and sealed all ducts, reducing indoor particulate by 60% per the homeowner’s air quality monitor. That combination — dehumidification plus filtration plus duct sealing — is often the right prescription for Loomis’s older homes with crawlspace or attic duct runs.

UV Air Purifier
UV-C systems target biological growth on coil surfaces, a real concern in Loomis homes where temperature swings create condensation cycles that encourage mold. We install UV systems sized to your air handler, with lamp replacement schedules you’ll actually remember because we mark them on your filter calendar.

Trusted Brands We Service in Loomis
We service your brand — whether that’s a Carrier Infinity air purifier, a Trane CleanEffects system, or a Bryant Perfect Air setup. Our technicians carry factory training or equivalent field experience across nine major HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Loomis customers, that means we stock common filtration media, UV lamps, and ERV core replacements locally, so you’re not waiting a week for a part that should be on the shelf. Diagnosed right the first time isn’t a slogan here; it’s what happens when the person reading your air-handler serial number has seen that exact model fail in three other Loomis homes.
Common Air Quality & Ventilation Problems We See in Loomis Homes
- Unsealed ductwork in unconditioned crawlspaces or attics introduces dust, pollen, and wildfire smoke directly into living spaces. We find this constantly in Loomis’s 1970s and 1980s custom builds, where original duct seams were never properly sealed and decades of rodent activity have added gaps. The fix is duct sealing with mastic plus filtration upgrades, not just a better filter on the return.
- Propane furnaces on rural parcels often lack fresh-air intake, causing negative pressure that pulls in garage fumes or crawlspace contaminants. This is virtually absent in Roseville’s all-electric or natural-gas subdivisions but shows up regularly on Loomis’s larger lots. Dedicated outdoor air intake or an ERV solves it.
- Short-cycling of heat pumps due to oversized equipment on large-lot homes results in poor humidity removal and stagnant air. Loomis’s custom homes with 3,000+ square feet and high ceilings get spec’d with too much cooling capacity too often. The system blasts cold air, shuts off fast, and never runs long enough to dehumidify properly.
- Wildfire smoke penetration through bathroom fans, range hoods, and dryer vents during negative-pressure events. When your heating system lacks makeup air, every exhaust fan in the house becomes an intake. We see this spike every August through October in Loomis.

FAQs — Air Quality & Ventilation in Loomis
Your system is likely recirculating the same air without introducing fresh outdoor air, a common issue in Loomis’s propane-heated homes that lack dedicated ventilation. We frequently find negative pressure from exhaust fans pulling against a sealed house, or oversized equipment that short-cycles before properly mixing air in large, vaulted spaces. An ERV or HRV installation, combined with duct sealing, typically resolves this. Call (844) 875-9451 for an exact quote — estimates are free.
Yes, a properly sized media filtration system with MERV 13 or higher capture rating will remove the fine particulate that wildfire smoke carries into Loomis through the I-80 corridor. We pair this with duct sealing to prevent smoke-laden air from entering through gaps in unconditioned spaces. The homeowner on Horseshoe Bar Road saw a 60% particulate reduction with this exact approach. Call (844) 875-9451 for an exact quote — estimates are free.
Almost certainly — original ductwork in Loomis’s unconditioned crawlspaces is typically unsealed, uninsulated, and often damaged by decades of moisture and rodent activity. We’ve found systems pulling in crawlspace dust, soil gases, and wildfire smoke directly into living spaces. Duct sealing with mastic, insulation repair, and filtration upgrades are the standard fix. Call (844) 875-9451 for an exact quote — estimates are free.
An Energy Recovery Ventilator (ERV) or Heat Recovery Ventilator (HRV) is typically the right choice, because propane furnaces lack the integrated ventilation that modern heat pumps provide. These systems bring in filtered fresh air while recovering heating or cooling energy, solving the stale-air problem without spiking your propane bill. We size them to your home’s specific air leakage rate and heating capacity. Call (844) 875-9451 for an exact quote — estimates are free.
Yes, we install whole-house humidifiers integrated with your central heating system, sized for the large floor plans and high ceilings common in Loomis’s custom homes. Proper humidity levels protect woodwork, reduce respiratory irritation, and let you run your thermostat lower while staying comfortable. Call (844) 875-9451 for an exact quote — estimates are free.
