Fast, Reliable Emergency & Commercial HVAC Across Kentfield
When your furnace fails on a foggy January morning or your AC quits during a 95°F Kentfield afternoon, you need an HVAC team that knows this specific microclimate, not a dispatcher reading from a script. We’re Crestview Heating & Air California, and we regularly make the run up from San Jose to serve Kentfield’s 94914 zip code and surrounding Ross Valley properties. You can reach us at (844) 560-6978 for emergency service or to schedule commercial maintenance.
Kentfield’s inland pocket traps heat that coastal Marin never sees. Morning marine layer, blazing afternoon sun, and salt air creeping over the hills from the bay — this combination breaks HVAC systems in predictable ways that out-of-area technicians often misdiagnose. We’ve spent nearly two decades learning those patterns.
Why Crestview Heating & Air California Is Kentfield’s Preferred Emergency & Commercial HVAC Company
Our Emergency & Commercial HVAC team has built a 4.8-star average across 250+ verified reviews by showing up personally and fixing systems right. Owner Marcus Feldman still serves as Service Manager, which means the same person who answers for the company’s reputation is the one reviewing your diagnostic and signing off on the repair plan. No layers. No handoffs to anonymous subcontractors.
Kentfield customers specifically mention our familiarity with older hydronic systems and our patience with the permitting process. Because Kentfield is unincorporated, every HVAC permit routes through the Marin County Community Development Agency, not a city building department. County inspectors enforce California Title 24 energy compliance and Bay Area Air Quality Management District gas-appliance rules with particular rigor. We’ve worked under these requirements long enough to prepare documentation correctly the first time. Out-of-area contractors regularly get caught off-guard by the extra steps.
Our 19 years in the industry means we’ve serviced virtually every system type found in Kentfield’s housing stock: original boiler-fed radiant heat from the 1930s–1960s, aging gas furnaces in 1970s–1980s builds, and the ductless mini-splits that have become the dominant retrofit solution for homes that were never built with ductwork.
Our Emergency & Commercial HVAC Services in Kentfield
24/7 Emergency HVAC
Kentfield’s extreme diurnal temperature swing — 50°F mornings, mid-90s afternoons — murders compressor capacitors and fan motors. We’ve responded to emergency calls at midnight when a heat exchanger cracked, and at 2 PM when a capacitor blew during peak load. Our emergency line is (844) 560-6978. We don’t quote exact arrival windows because traffic from San Jose varies, but we prioritize Kentfield calls and dispatch with local knowledge of which routes avoid Sir Francis Drake Boulevard backups during commute hours.
Commercial HVAC
Commercial properties along Kentfield’s main corridors and in the Kent Woodlands area need systems that handle both heating and real cooling capacity — a dual demand that pure coastal Marin rarely faces. We service package units, split systems, and the specialized equipment found in professional offices and retail spaces. Our factory training across nine major brands means we don’t turn away commercial customers because “we don’t work on that manufacturer.”
Rooftop Unit Service
Kentfield’s commercial and light-industrial buildings with rooftop units face accelerated coil corrosion from salt air that drifts over the hills from San Francisco Bay. We inspect for fin degradation, refrigerant leaks at braze joints, and condensate drain blockages caused by particulate matter. For businesses near the intersection of Wolfe Grade and Sir Francis Drake, this is a recurring maintenance issue that preventive service catches before July heat waves.
Chiller Service
While full chillers are less common in Kentfield’s smaller commercial footprint than in San Jose, we do service the compact chillers and chilled-water systems found in some larger estate properties and small institutional buildings. The same salt-air corrosion that attacks rooftop coils affects chiller condensers and cooling towers. We descale, pressure-test, and rebuild as needed.
Annual Maintenance & HVAC Inspection
Given Kentfield’s temperature swings and coastal air, we recommend bi-annual maintenance rather than the single annual visit that might suffice inland. Pre-summer inspection catches capacitor and contactor wear before peak load. Pre-winter service checks heat exchanger integrity and combustion safety on the gas furnaces and boilers that still heat many Kentfield homes.

Trusted Brands We Service in Kentfield
We maintain factory-trained compatibility across Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Kentfield customers, this matters because many homes have mixed systems — a Lennox furnace added in the 1980s, a Goodman condenser from a 2005 replacement, or a recent Daikin ductless mini-split retrofit. We stock common parts for Trane, Lennox, Goodman, and Rheem systems to minimize return trips. If you own a Carrier rooftop unit at your Kentfield business, we can service it. If your home has an aging Bryant boiler, we’ve worked on hundreds. Your system, our specialty.
Common Emergency & Commercial HVAC Problems We See in Kentfield Homes
- Compressor capacitor failure during heat spikes. The 40–50°F daily temperature swing in Kentfield stresses start capacitors more than steady climates. We replace with higher-temp-rated components that handle the cycling.
- Refrigerant leaks in coastal-corroded coils. Salt air accelerates pitting in aluminum condenser fins and copper tubing. We find leaks with electronic detection, repair where possible, and specify corrosion-resistant coatings on replacements.
- Overworked ductless compressors in homes that never had central air. Many Kentfield properties had mini-splits added as afterthoughts, sized for modest cooling loads. When 95°F hits, these systems run continuously and eventually fail. We recalculate loads and specify properly sized multi-zone systems.
- Cracked heat exchangers in aging forced-air additions. The 1950s–1960s homes with original radiant heat sometimes got ducted furnaces added later, often installed with minimal clearance and poor return airflow. We inspect with cameras and replace with modern high-efficiency units or recommend ductless conversion.
Pricing for Emergency & Commercial HVAC in Kentfield, CA
Honest pricing starts with real numbers. Here’s what typical Kentfield HVAC service runs:
| Service | Price Range in Kentfield |
|---|---|
| AC Repair | $150–$650 |
| Furnace Repair | $150–$700 |
| AC Installation | $3,500–$7,500 |
| Tune-Up / Maintenance | $95–$235 |
Several factors push Kentfield jobs toward the higher end of these ranges. Homes without existing ductwork require more labor for any forced-air solution. Marin County’s permitting process adds inspection fees and documentation time. And the architectural significance of many Kentfield properties demands careful work around plaster-and-lath walls, custom trim, and landscaping that can’t be disturbed.
We provide upfront written estimates before any work begins. Call (844) 560-6978 for a free estimate — we’ll assess your specific system and give you an exact number, not a guess.
We Also Serve Cities Near Kentfield
Our service radius covers the full Ross Valley and central Marin County. We regularly work in Larkspur, San Anselmo, Corte Madera, and Fairfax — each with its own microclimate quirks and permitting paths. Larkspur’s commercial corridor has different load profiles than Kentfield’s residential estates. San Anselmo’s older housing stock resembles Kentfield’s but with more 1920s-era construction. Corte Madera’s mixed commercial-residential zones need flexible scheduling. Fairfax’s slightly higher elevation sees more frost-heating demand. Wherever you are in central Marin, the same owner-managed service applies.

FAQs — Emergency & Commercial HVAC in Kentfield
Yes, most HVAC work in unincorporated Kentfield requires a permit through the Marin County Community Development Agency, even for some repairs that incorporated cities might allow without paperwork. Emergency repairs that restore essential heating or cooling can often proceed immediately with permit application within the next business day, but the county still enforces Title 24 efficiency standards and BAAQMD gas-appliance rules. We handle all permit documentation as part of our service. Call (844) 560-6978 and we’ll confirm exactly what your specific repair requires.
Salt air accelerates corrosion of condenser coils, electrical connections, and metal housings by several years compared to inland locations. For commercial rooftop units, we see fin degradation and refrigerant leaks that require more frequent preventive maintenance and earlier replacement of affected components. We specify corrosion-resistant coatings and materials on new installations. If your Kentfield business has equipment showing rust or reduced efficiency, schedule an inspection at (844) 560-6978.
Commercial rooftop unit repairs in Kentfield typically run $400–$1,800 depending on whether the issue is electrical, refrigerant-related, or requires compressor work. Salt-air corrosion and the need for Marin County permitting on major component replacements push costs toward the higher end compared to inland markets. We provide itemized estimates before beginning any commercial repair. Call (844) 560-6978 for a free assessment of your specific unit.
Yes, we are factory-trained to service Carrier rooftop units and carry common Carrier parts for faster turnaround on Kentfield commercial calls.
