Why Stonegate Heating & Air California Is Corte Madera’s Preferred Emergency & Commercial HVAC Company
We’ve spent 16 years building a reputation across California for showing up when we say we will and fixing what others patch. In Corte Madera specifically, that means understanding the bay-marsh conditions that destroy standard HVAC equipment. Nearly 500 verified reviews averaging 4.7 stars back our work, and owner Jason Trent still serves as active Field Supervisor, meaning he’s physically on job sites, not managing from a back office.
Our response to Corte Madera is built around the reality of this town: flatland ranch homes with crawl spaces that stay wet year-round, hillside commercial buildings with rooftop units exposed to salt air, and detached workshops on acreage properties that need heavy-duty systems installed right the first time. Jason supervises every project, so the technician who arrives knows exactly what they’re walking into, whether it’s a moisture-compromised duct system near Paradise Drive or a commercial RTU on a hillside building off Tamalpais Drive.
Our Emergency & Commercial HVAC Services in Corte Madera
24/7 Emergency HVAC
HVAC failures in Corte Madera don’t wait for business hours. A rusted-through galvanized duct run in a flatland crawl space can shut down your system overnight. Salt-corroded condenser coils near the bay marsh line often fail during the first autumn rain. We carry parts for Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard, so we’re not making a second trip. Emergency HVAC available means you call, we move.
Commercial HVAC
Corte Madera’s commercial buildings range from low-slung retail along Tamalpais Drive to hillside offices with multi-zone complexity. Original 1960s single-pane windows and minimal insulation in many flatland structures create heat gain and loss patterns that cause oversized RTUs to short-cycle and freeze up in Corte Madera’s mild marine weather. We size correctly for actual loads, not outdated assumptions.
Rooftop Unit Service
Hillside commercial buildings in Corte Madera put rooftop units in direct path of salt-laden bay breezes off Richardson Bay. We’ve replaced RTU coils that failed years before their rated life because the salt air found every seam. Our annual maintenance program catches corrosion before it kills the compressor.
Chiller Service
Commercial chillers in Corte Madera face the same marine-humidity challenges as other outdoor equipment, with the added complexity of continuous operation demands. We service and repair chiller systems for local businesses, with factory-trained experience on major brands including Carrier and Daikin.
Annual Maintenance
Given Corte Madera’s unique corrosion environment, annual maintenance isn’t optional here, it’s survival. Our tune-up service runs $80–$200 and includes crawl-space duct inspection, coil cleaning with salt-deposit removal, and refrigerant leak detection. Catching a pinhole leak before autumn rain saves you from an emergency call.
HVAC Inspection
Before you buy a Corte Madera property, especially in the 94925 or 94976 ZIP codes, get the HVAC inspected by someone who knows what bay-marsh moisture does to systems. We document duct condition, corrosion levels on outdoor equipment, and whether previous owners installed proper vapor barriers.

Trusted Brands We Service in Corte Madera
We stock parts and have factory-trained experience on nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard.

Whether you have a 20-year-old Bryant furnace in a flatland ranch or a new Daikin heat pump on a hillside contemporary, our technicians arrive prepared. We keep common failure parts in stock for faster turnaround, because in a salt-air environment, equipment doesn’t give you extra time.
Common Emergency & Commercial HVAC Problems We See in Corte Madera Homes
- Galvanized duct runs rust through from persistent bay moisture. The water table under portions of the flatlands stays close to the old marsh grade, and moisture wicks into unconditioned crawl spaces year-round. We’ve pulled apart 1960s duct runs that smelled of salt and organic mud, with airflow loss so severe the system shut down on high-limit.
- Outdoor condenser coils develop pinhole leaks from salt corrosion. Homes near the bay marsh line see coil fins disintegrate years ahead of inland Marin. The first autumn rain often pushes a weakened coil into complete failure.
- Oversized commercial RTUs short-cycle and freeze up. Original single-pane windows and minimal insulation in flatland buildings create load calculations that don’t match Corte Madera’s mild summers. Equipment cycles on and off too frequently, icing the evaporator.
- Flex duct without vapor barriers grows visible mold within seasons. The marine humidity baseline here is higher than San Rafael or Novato, and any shortcut on installation materials shows up fast in a Corte Madera crawl space.

FAQs — Emergency & Commercial HVAC in Corte Madera
The flatlands sit on filled Richardson Bay tidal marsh, so crawl spaces stay persistently moist and salt-laden bay breezes corrode outdoor components faster than in any inland Marin town. We answered an emergency call on a flatland ranch near Paradise Drive where the outdoor condensing unit, a 15-year-old Carrier, had its coil fins disintegrated by salt air from Richardson Bay. We replaced it with a sealed-combustion heat pump, upgraded the flex ducts in the crawl space with vapor barrier insulation, and sealed the slab penetrations to stop the mud smell. One trip, done right. Call (855) 467-1888 if you’re seeing premature corrosion.
Yes, absolutely. The moisture wicking from the old marsh grade makes unprotected flex duct grow visible mold within a few seasons. We specify vapor-barrier-insulated duct and sealed slab penetrations on every Corte Madera flatland job. Call (855) 467-1888 for a crawl-space inspection and exact quote, estimates are free.
Yes, we service and repair rooftop units on hillside commercial properties throughout Corte Madera, including buildings off Tamalpais Drive and near Ring Mountain. Salt exposure is actually worse at elevation where bay breezes hit unobstructed, so our annual maintenance program includes corrosion-specific inspection. Call (855) 467-1888 to schedule.
We recommend sealed-combustion heat pumps from Carrier, Daikin, or American Standard for Corte Madera’s salt-air environment, because their coil coatings and cabinet sealing resist corrosion better than standard models. Whatever brand you have, we stock parts for nine major lines and can install same-day in most emergencies. Call (855) 467-1888 for availability.
Twice yearly, spring and fall, because the marine humidity and salt air here accelerate wear beyond what annual service can catch. Our $80–$200 tune-up includes crawl-space duct inspection, coil cleaning with salt-deposit removal, and refrigerant leak detection. Call (855) 467-1888 to book your first maintenance visit.
