Why Redwood Heating & Air San Diego Is San Rafael’s Preferred Emergency & Commercial HVAC Company

Gregory Hahn founded this company and still leads every technical decision. That means when you call us for emergency service in San Rafael, you’re getting owner-level accountability, not a franchise dispatcher sending the next available crew. Our 428 verified customer reviews averaging 4.6 stars were earned over 13 continuous years, and a meaningful share come from Marin County property owners who’ve learned the hard way that not every HVAC contractor understands San Rafael’s unique conditions.

We’ve spent enough time in San Rafael to know the difference between a flatland permit in 94901 and a hillside job in the high-fire zones above downtown where CalFire’s ember-resistant vent requirements apply. Coastal Bay Area crews used to mild Sausalito summers routinely underestimate the valley heat here. We don’t. Our response time to San Rafael averages under 90 minutes for emergency calls placed before 6 PM, and we carry parts for Carrier, Bryant, and American Standard systems commonly found in local homes.

Our Emergency & Commercial HVAC Services in San Rafael

24/7 Emergency HVAC

Furnace failures at midnight. AC compressors seizing during afternoon Diablo wind peaks. We answer emergency calls across San Rafael’s 94901, 94903, 94912, 94913, and 94915 zip codes with technicians who carry the tools and common parts to complete most repairs in a single visit. Our after-hours emergency rate applies only to calls outside normal business hours; we don’t charge premium rates for calls placed at 4 PM on a Tuesday just because it’s July. If your system is dead and your home or business is becoming unlivable, call (844) 875-9451.

Commercial HVAC

San Rafael’s commercial base runs from professional offices along Lindaro Street to retail in the Northgate mall area to light industrial near the canal. We service packaged rooftop units, split systems, and VRF installations for businesses throughout the city. Our multi-brand fluency matters here: a commercial Bryant rooftop unit and a Daikin VRF system require different diagnostic approaches, and we’ve factory-trained experience with both. We also understand that commercial downtime costs money, so we prioritize repairs that keep your business operational while planning permanent solutions.

Rooftop Unit Service

Flat-roof commercial buildings in San Rafael’s commercial corridors often rely on packaged rooftop units that take a beating from summer heat and winter valley fog. We handle everything from belt and bearing replacements to full compressor swaps and economizer repairs. Access can be tricky on older buildings near downtown; we’ve worked with property managers to coordinate crane lifts on Fourth Street buildings where roof loading limits standard equipment. Our master-technician diagnosis means we identify whether your RTU needs a $400 repair or a $6,500 replacement, not a guess that wastes your money.

Chiller Service

While smaller than San Francisco’s commercial base, San Rafael does have facilities with process cooling and comfort chillers, particularly in medical and professional buildings near the Kaiser campus and along Bon Air Road. We service scroll and screw chillers, handle refrigerant management per EPA requirements, and troubleshoot control sequences that have drifted out of calibration. Chiller problems rarely fix themselves, and running a failing unit to failure typically doubles the repair cost.

Annual Maintenance

Annual maintenance in San Rafael isn’t a luxury, it’s survival planning for a climate that stresses equipment in both directions. Our tune-up service runs $80–$200 and includes full system inspection, filter replacement, refrigerant level check, electrical connection tightening, and combustion analysis on gas-fired equipment. For Terra Linda homes with original duct systems, we specifically check static pressure and airflow, since undersized ducts are the hidden cause of most “mysterious” AC problems in 1960s ranch retrofits.

Trusted Brands We Service in San Rafael

We service your brand. Our technicians carry factory training or equivalent field experience across nine major HVAC lines: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. In San Rafael specifically, we see a lot of Carrier and Bryant equipment in Terra Linda homes where those brands were popular during the 1980s and 1990s replacement cycle, plus newer American Standard installations in Lucas Valley corridor builds. We stock common parts for these brands locally, which means faster turnaround on repairs and fewer return trips. If you’re running a less common brand, we can still diagnose and repair; our master-technician background means we understand systems, not just memorized procedures for one product line.

Common Emergency & Commercial HVAC Problems We See in San Rafael Homes

• Original furnace failure in Terra Linda ranches with no AC infrastructure. These 1960s homes were built with heating-only gas furnaces and ducts sized for winter airflow. When we retrofit cooling, the entire system needs re-engineering. We handled an emergency call in Terra Linda’s Las Colindas neighborhood where a 1968 ranch home’s original furnace failed during a Diablo wind event pushing 98°F. The home had no AC, so we retrofitted a complete split-system with a new duct layout, condenser pad, and 240V circuit, installing a Carrier Performance series and a Wi-Fi thermostat for $6,200.
• Retrofit AC freezing up due to undersized ductwork. Adding a cooling coil to a heat-only duct system restricts airflow below manufacturer minimums. The coil ices, the compressor short-cycles, and homeowners call us thinking they need a new unit when they actually need proper duct design. This is the most common “emergency” we see in Terra Linda that isn’t actually a component failure.
• Ember-resistant vent violations in hillside fire zones. Homes above downtown San Rafael and along portions of Lucas Valley Road fall within CalFire High Fire Hazard Severity Zones. Standard louvered vents fail inspection. Contractors unfamiliar with local zone mapping get flagged, forcing costly rework. We check zone status before ordering materials.
• Commercial RTU economizer stuck on “minimum” position. San Rafael’s mild spring and fall weather should let rooftop units use outside air for free cooling, but failed economizer actuators or disconnected linkages lock them on minimum ventilation. The unit runs mechanical cooling when it shouldn’t, and your PG&E bill reflects it.
