Larkspur isn’t like the rest of Marin County. The valley traps heat. The bayfront corrodes equipment. Old Town Victorians have no ducts. We’ve worked on Magnolia Avenue cottages, hillside ranch homes, and commercial buildings near Larkspur Landing long enough to know that generic HVAC advice fails here. Our Emergency & Commercial HVAC team is led by owner Marcus Feldman, who still manages every job personally.
Why Crestview Heating & Air California Is Larkspur’s Preferred Emergency & Commercial HVAC Company
We’ve earned a 4.8-star average across 250+ customer reviews because we show up prepared for Larkspur’s realities. That means carrying coated coils for bayfront properties, knowing which Title 24 permits Marin County requires for Old Town retrofits, and understanding that a 95°F afternoon in Larkspur’s valley demands different equipment sizing than a 72°F day in Sausalito.
Marcus Feldman doesn’t delegate to anonymous technicians. As both owner and Service Manager, he’s on-site for complex emergency calls and commercial inspections. When we responded to that emergency on Magnolia Avenue in Old Town Larkspur, the 1910 Victorian’s wall-mounted AC had seized from salt-air corrosion on a 95°F afternoon. We diagnosed the failed compressor, sourced a coated Daikin mini-split system, and completed the replacement during the same visit. That’s owner-managed accountability, not outsourced dispatch.
Our familiarity with 9 major brands, Trane, Lennox, Goodman, and Rheem included, means we don’t turn away jobs because “we don’t work on that.” From emergency compressor replacements to commercial rooftop units, your system is our specialty.
Our Emergency & Commercial HVAC Services in Larkspur
24/7 Emergency HVAC
HVAC failures in Larkspur rarely happen at convenient times. The valley heat peaks between 2 and 6 PM, right when older compressors are most likely to overheat and shut down. We take emergency calls throughout Larkspur, including hillside neighborhoods where access can be tight and Old Town streets where parking a service van requires local knowledge. Our emergency rates are straightforward: AC repair typically falls between $150–$650, furnace repair between $150–$700, depending on parts and labor.

Commercial HVAC
Commercial buildings near Larkspur Landing, along Larkspur Landing Circle and the ferry terminal corridor, face a dual challenge: high cooling loads from afternoon valley heat and accelerated corrosion from salt-laden bay air. We service packaged rooftop units, split systems, and ventilation equipment for retail, restaurant, and office properties. Our commercial inspections identify corrosion before it causes shutdowns, and we specify coated coils and stainless hardware for waterfront installations.

Rooftop Unit Service
Rooftop units on Larkspur’s commercial buildings take a beating. The combination of direct sun exposure and salt air near the waterfront means condenser coils degrade faster than inland locations. We perform seasonal inspections, refrigerant leak detection, and compressor testing. When replacement is necessary, we size units correctly for Marin County’s Title 24 energy code and Larkspur’s actual cooling load, not a generic coastal assumption.

Chiller Service
While smaller than San Jose’s commercial market, Larkspur’s hospitality and medical office buildings rely on chillers for precise climate control. We handle chiller diagnostics, refrigerant management, and controls calibration. Given Larkspur’s temperature swings between cool mornings and hot valley afternoons, chiller capacity and staging must be tuned for real local conditions, not textbook coastal profiles.

Annual Maintenance & HVAC Inspection
Our tune-ups run $80–$200 and include coil cleaning, refrigerant level checks, electrical testing, and corrosion inspection. For Larkspur properties, we pay special attention to condenser coil condition on bayfront units and ductless line set integrity in Old Town retrofits. Annual maintenance catches the salt-air damage and heat-stress failures before they become emergency calls.

Trusted Brands We Service in Larkspur
We maintain factory-trained compatibility across Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Larkspur customers, this means we stock common parts locally and don’t need to special-order components that delay repairs. We’ve installed Goodman systems in hillside ranch homes, serviced Trane commercial rooftops near the ferry terminal, and specified Rheem equipment for salt-exposed bayfront properties. When your system fails on a 90°F Saturday, that parts availability matters.
Common Emergency & Commercial HVAC Problems We See in Larkspur Homes
- Salt-air corrosion near Larkspur Landing. Condenser coils and cabinet panels on standard units corrode within 5–7 years, causing refrigerant leaks and compressor failure. We specify coated coils and elevated mounting for waterfront installations.
- Compressor overheating in hillside ranch homes. The 1950s–70s homes east and north of Old Town often have undersized duct systems that can’t move enough air for valley heat peaks. We see emergency calls every summer when original compressors finally give out.
- Balloon-frame routing challenges in Old Town. Victorian and Craftsman cottages on Magnolia Avenue and surrounding streets have no supply or return chases. Emergency repairs often require creative lineset routing through closets or crawl spaces, work that demands field experience, not textbook training.
- Failed wall-mounted AC units in pre-1920 homes. Many Old Town owners installed through-wall or window units as stopgaps. These fail predictably in heat waves, and replacement with proper ductless mini-splits requires Title 24 compliance and careful load calculation.

FAQs — Emergency & Commercial HVAC in Larkspur
Salt-laden bay air accelerates corrosion of condenser coils, cabinet panels, and electrical connections by years compared to inland Marin locations. Standard slab-mounted condensers without coated coils typically require replacement within 5–7 years near the ferry terminal, while properly specified equipment with corrosion-resistant finishes lasts significantly longer. Call (844) 560-6978 if your waterfront unit is showing rust or refrigerant loss, estimates are free.
True central AC with ductwork is rarely practical in Old Town’s balloon-frame Victorians because these homes were built with no supply or return chases and limited attic depth. We install multi-zone ductless mini-split systems instead, which provide cooling without invasive duct installation and comply with Marin County’s Title 24 energy requirements. Call (844) 560-6978 for a free assessment of your specific property.
Commercial properties near Larkspur Landing most commonly experience refrigerant leaks from corroded rooftop unit coils, compressor failure from undersized equipment cycling in valley heat, and ventilation imbalance from salt-damaged economizer controls. Office buildings in the Magnolia Avenue corridor often have aging package units that fail during peak afternoon temperatures. Call (844) 560-6978 for emergency commercial service, we carry parts for all 9 major brands.
Larkspur’s mild winters mean furnaces run less than inland California locations, which actually increases corrosion risk from condensation sitting in heat exchangers during long off-cycles, especially in humid bayfront conditions. We find cracked heat exchangers and failed ignition components more often from disuse damage than wear. Annual inspection catches these before they become safety hazards or mid-winter failures. Call (844) 560-6978 to schedule a furnace tune-up.
Yes, Marin County requires Title 24 energy compliance documentation and mechanical permits for all mini-split installations, including replacements of existing equipment. The permitting process adds time and cost compared to unpermitted work, but compliance protects your property value and ensures proper load calculation. We handle permit submission as part of our installation service. Call (844) 560-6978 for a free estimate that includes permit costs.
