Fast, Reliable Emergency & Commercial HVAC Across Loomis
When your heat pump locks out on a 10°F January night or your propane furnace soots up before a hard freeze, you need a technician who understands Loomis — not a dispatcher reading from a Sacramento script. We’re Redwood Heating & Air, and our Emergency & Commercial HVAC team has been responding to calls across the 95650 ZIP code and surrounding Placer County foothills for 13 years. Gregory Hahn founded this company and still leads every technical decision, which means when you call (844) 875-9451, you’re getting master-technician diagnosis, not a rushed sales pitch.
Loomis isn’t Roseville. The semi-rural ranchette properties, custom homes from the 1970s through early 2000s, and large-lot horse properties here create HVAC challenges that template-driven crews simply miss. We’ve replaced compressors on Horseshoe Bar Road at midnight and sized propane lines for conversions off King Road. That local fluency matters when every hour without heat risks frozen pipes or lost livestock.
Why Redwood Heating & Air San Diego Is Loomis’s Preferred Emergency & Commercial HVAC Company
Our reputation in Loomis was built one call at a time. Gregory Hahn holds a Master Technician designation, and that credential rides in every truck — not framed in a corporate office 50 miles away. We’ve earned 428 verified customer reviews averaging 4.6 stars over 13 continuous years, and a significant share of those come from repeat customers in Placer County who’ve learned that brand-agnostic expertise saves them money and headaches.
Response time to Loomis typically runs 45–90 minutes from dispatch, depending on whether you’re near the I-80 corridor or deeper into the foothills toward Penryn. We keep common parts for Carrier, Trane, Bryant, and American Standard units on our trucks because rural Loomis calls don’t allow for a parts-run to Sacramento during a freeze.
What separates us from one-brand dealers and franchise dispatchers is simple: we service your brand. Nine major HVAC brands — Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard — and we diagnose across all of them. From a single mini-split to a full commercial system, the right fix, not the convenient upsell.
Our Emergency & Commercial HVAC Services in Loomis
24/7 Emergency HVAC
Propane furnace orifice clogging from decades-old fuel lines. Heat pump low-ambient lockouts when foothill temps plunge below 10°F. Rooftop unit compressor failures during 105°F July afternoons. We’ve handled all of them in Loomis, and we don’t clock out at 5 PM. Our emergency line — (844) 875-9451 — routes directly to Gregory Hahn’s team, not an overseas call center. During a July heat wave, we responded to a commercial rooftop unit failure at a horse property on Horseshoe Bar Road. The 15-year-old Lennox unit had a seized compressor on an all-electric system; we expedited a replacement and installed a new media filter to handle wildfire smoke infiltrating from the Sierra corridor — restoring cooling within 6 hours.

Commercial HVAC
Loomis’s commercial base spans equine facilities, light industrial along Taylor Road, and small retail near the historic downtown. Each carries distinct load profiles. Horse properties generate ammonia-laden air that corrodes rooftop condenser coils faster than standard commercial environments. We size equipment for those realities, not textbook assumptions. Annual maintenance contracts are available for Loomis businesses that can’t afford downtime during boarding season or harvest periods.

Rooftop Unit Service
Commercial RTUs in Loomis fight a three-front battle: summer heat load from 100°F+ days, winter freeze cycles, and airborne contaminants from agricultural operations. We inspect heat exchangers for corrosion, verify refrigerant charge against manufacturer specs, and check economizer operation — critical when wildfire smoke turns the Sierra corridor into a particulate corridor each August and September. Replacement units are spec’d for low-ambient operation because Loomis winters demand it.

Chiller Service
While less common than packaged RTUs, chillers serve several larger commercial and institutional properties in the Loomis area. Gregory Hahn’s Master Technician background includes chiller diagnostics, refrigerant management, and cooling tower maintenance. We handle reciprocating, scroll, and screw compressors across multiple manufacturers, with evacuation and charging protocols that meet California environmental requirements.

Annual Maintenance & HVAC Inspection
Annual maintenance in Loomis isn’t a luxury — it’s survival math. The 60–70°F seasonal temperature swing here outstrips Sacramento’s milder curve, and systems that aren’t combustion-analyzed, refrigerant-verified, and filter-checked before each extreme season fail at the worst possible moment. Our tune-ups run $80–$200 and include full system analysis, not a cursory glance. For commercial clients, we document everything for insurance and warranty compliance.

Trusted Brands We Service in Loomis
We maintain active technical fluency across Carrier, Trane, Bryant, and American Standard — four of the nine brands we certify — and we stock common failure parts for Loomis customers rather than ordering from Sacramento after diagnosis. That inventory discipline matters when you’re on propane heat and it’s 18°F outside. We don’t push brand switches unless your existing equipment is genuinely unrepairable; our bias is toward fixing what you have, correctly, because Gregory Hahn built this company on repeat customers, not one-time replacement commissions.
Common Emergency & Commercial HVAC Problems We See in Loomis Homes
- Propane furnace orifice clogging from aging fuel lines on rural parcels. Decades-old copper or black-iron lines shed particulate that lodges in burner orifices, causing delayed ignition, flame rollout, and potential sooting. We combustion-analyze and orifice-gauge every propane furnace we touch — specs a natural-gas tech from Roseville might not have top of mind.
- Heat pump low-ambient lockouts during January hard freezes. When overnight temps drop below 10°F, standard heat pumps defrost-cycle into uselessness. Loomis homes need either propane dual-fuel backup or cold-climate heat pumps rated for sub-zero operation — a sizing decision we make before installation, not after the first frozen night.
- Rooftop unit condenser coil corrosion near horse stalls and agricultural buildings. Ammonia from animal waste accelerates copper fin deterioration and refrigerant leaks. We spec coated coils and more frequent maintenance intervals for Loomis commercial clients in equine or agricultural settings.
- Uneven cooling in custom homes with vaulted or exposed-beam ceilings. The 1970s–2000s custom ranch homes dominating Loomis frequently have great-room layouts that defeat single-zone ducting. We design zoned systems with motorized dampers and multiple thermostats rather than oversizing equipment and cycling it to death.
Pricing for Emergency & Commercial HVAC in Loomis, CA
Here’s what typical work runs in the Loomis market. These ranges reflect actual invoices from Placer County jobs — not national averages or teaser rates that balloon on arrival.
| Service | Price Range in Loomis |
|---|---|
| AC Repair | $150–$650 |
| Furnace Repair | $150–$700 |
| AC Installation | $3,500–$7,500 |
| Tune-Up / Annual Maintenance | $80–$200 |
What moves the needle within these ranges? For repairs, it’s parts — a capacitor versus a compressor. For installation, it’s system size, ductwork modifications (common in Loomis’s custom homes), and whether we’re converting from all-electric to propane dual-fuel. In Loomis, many custom ranch homes built before 2000 were designed with all-electric HVAC systems, but recent PG&E rate hikes have driven a surge in propane conversions — an engineering challenge that requires careful venting and gas-line sizing rarely needed in grid-tied Roseville. That conversion complexity can push installation toward the upper end of our range.
Commercial emergency calls carry after-hours premiums, but we quote upfront — no “diagnostic fee” that triples when the tech arrives. Call (844) 875-9451 for an exact quote. Estimates are free.
We Also Serve Cities Near Loomis
Our service radius covers the full Placer County foothills corridor, including Rocklin, Granite Bay, Roseville, and North Auburn.

We adjust our technical approach accordingly, but the master-technician standard stays constant.

FAQs — Emergency & Commercial HVAC in Loomis
Yes, we perform propane dual-fuel conversions for Loomis properties outside PG&E’s natural gas distribution lines. The work requires proper gas-line sizing, combustion-air calculations, and venting design that meets Placer County code — engineering steps we handle in-house rather than subcontracting. Conversions typically run toward the upper end of our AC installation range ($3,500–$7,500) depending on existing ductwork and electrical panel capacity. Call (844) 875-9451 and we’ll assess your specific property.
Yes, our emergency line operates 24/7 and routes directly to Gregory Hahn’s technical team, not a third-party dispatcher. Response time to Taylor Road and surrounding commercial areas typically runs 45–90 minutes. We stock compressors, contactors, and capacitors for major brands on our trucks to minimize downtime. Call (844) 875-9451 — we’ll have a technician en route.
Yes, sooting indicates incomplete combustion and poses carbon monoxide risk — shut the unit off and call us immediately. In Loomis, we see this most often from orifice clogging in aging propane lines or improper fuel-pressure settings at the regulator. Our combustion analysis identifies the root cause before we quote any repair. Call (844) 875-9451 for emergency inspection.
Yes, zoned duct systems with motorized dampers and multiple thermostats are our standard solution for Loomis’s custom ranch homes with vaulted or exposed-beam ceilings. We perform Manual J load calculations specific to your home’s volume and insulation rather than applying square-footage rules designed for flat-ceiling tract homes. Most zoned retrofits fall within our AC installation range. Call (844) 875-9451 for a free assessment.
Yes, we install MERV 13+ media filters and sealed return systems that capture wildfire particulate from the Sierra corridor, which funnels directly through the I-80 corridor past Loomis each fire season. For severe smoke events, we can spec HEPA-grade filtration and positive-pressure strategies. Media filter upgrades typically add $200–$600 to a standard maintenance visit. Call (844) 875-9451 to discuss your specific air-quality concerns.
