Fast, Reliable Emergency & Commercial HVAC Across San Martin
When your propane furnace quits at midnight or your workshop rooftop unit locks up during a 105°F August afternoon in San Martin, you need an HVAC team that understands this zip code’s quirks. We’re Crestview Heating & Air California, and we answer emergency calls throughout 95046 — from the ranchette properties along Monterey Road to the custom ranch homes near San Martin Avenue. Our Emergency & Commercial HVAC team is led by owner Marcus Feldman, who still manages jobs in the field. Call (844) 560-6978 for same-day service.
Why Crestview Heating & Air California Is San Martin’s Preferred Emergency & Commercial HVAC Company
We’ve been driving to San Martin for nearly two decades. That matters here. This isn’t a standard suburban market where every house has natural gas and a 1,200-square-foot footprint. San Martin’s semi-rural properties demand technicians who know to check propane tank levels before declaring a furnace dead, and who carry coil cleaner specifically formulated for agricultural dust, not just city pollen.
Our 4.8-star average across 250+ customer reviews reflects this kind of specialized work. San Martin property owners have left us reviews mentioning exactly what we expect: fast diagnosis of propane pressure issues, willingness to service detached barn units other companies won’t touch, and showing up when promised even during harvest season traffic on Highway 101.
Marcus Feldman answers as Service Manager, not a dispatcher reading from a script. Owner-managed, not outsourced. That’s why a San Martin customer last March got a 2:00 AM emergency furnace repair on a Sunday instead of a voicemail box.
Our Emergency & Commercial HVAC Services in San Martin
24/7 Emergency HVAC
Propane furnaces fail differently than natural gas systems, and San Martin has more of them than anywhere else in Santa Clara County. When your unit quits, we confirm fuel source, check tank access paths, and verify propane pressure at the regulator before touching a wrench. Emergency calls from Bailey Avenue, Llagas Road, or the ranchettes off San Martin Avenue get priority routing because we keep common propane valves, orifices, and regulators stocked for this market. Call (844) 560-6978 — estimates are free, even at odd hours.

Commercial HVAC
San Martin’s commercial load isn’t typical retail. We’re talking winery tasting rooms, agricultural processing facilities, horse barns with climate-controlled tack rooms, and equipment workshops on multi-acre parcels. These buildings need zoned systems, often multiple units, and technicians comfortable with propane conversions. Our 19 years in the field means we’ve worked on virtually every configuration these properties throw at us.

Rooftop Unit Service
Detached workshops and guest quarters across San Martin frequently use rooftop package units to save ground space. They’re exposed out here. No neighboring buildings to break the wind or filter the dust. During spring and fall harvest seasons, row crop and garlic field particulate coats condenser fins and clogs return air paths. We schedule coil cleaning around the agricultural calendar, not just when something breaks.

Chiller Service
Wineries and food processing operations near San Martin rely on process chillers that can’t afford downtime during crush season. Our team services chillers for commercial clients who need precise temperature control, and we maintain emergency parts availability for critical cooling loads when the Santa Clara Valley hits triple digits.

Annual Maintenance
Annual maintenance in San Martin isn’t a checkbox. It’s survival planning. We clean condenser coils before harvest dust peaks, verify propane system integrity before heating season, and test static pressure on those long duct runs that were likely undersized when the house was built in 1975. Your system, our specialty — whatever brand, whatever fuel, whatever building type.

HVAC Inspection
Buying a ranchette on 2 acres off Monterey Road? The inspection needs to cover more than the house. We evaluate detached structures, propane tank placement and line condition, and whether the existing ductwork can actually cool 3,000 square feet when it’s 102°F outside. Our inspection reports flag what generic home inspectors miss.

Trusted Brands We Service in San Martin
Your system, our specialty. We stock parts and have factory-trained compatibility across nine major brands, including Trane, Lennox, Goodman, and Rheem. For San Martin customers, this means faster turnaround when your propane-converted Rheem furnace needs a gas valve or your Lennox rooftop unit needs a control board. We don’t tell you “we don’t work on that.” We fix it. Our parts network reaches San Martin within hours, not days, because we’ve built relationships with distributors who understand this isn’t a standard suburban market.
Common Emergency & Commercial HVAC Problems We See in San Martin Homes
- Condenser coils choked with agricultural dust. San Martin sits surrounded by row crops and garlic fields. The particulate load here is industrial-grade compared to San Jose. Outdoor units need coil cleaning twice yearly minimum, timed before spring planting and fall harvest, or the compressor labors itself to death.
- Propane furnace ignition failures in uninsulated tank sheds. Moisture condenses on regulators and valves when tanks sit in open-air enclosures without weather protection. We see this constantly on older San Martin properties where the original installer never considered freeze protection.
- Uneven cooling from undersized ductwork on sprawling ranch homes. That 1970s ranch with the 80-foot duct run to the master bedroom? The static pressure is probably double what the blower was designed for. We measure it, then design retrofits that actually move air to the far end of the house.
- Workshop rooftop units failing from exposure. Detached buildings get no windbreak, no shade, and often no maintenance attention until they quit. We install fine-mesh pre-filters and schedule dedicated service for these orphaned systems.
Pricing for Emergency & Commercial HVAC in San Martin, CA
Here’s what typical jobs run in the 95046 market. These ranges reflect San Martin’s specific conditions: longer drive times for rural properties, propane system complexity, and the heavier maintenance load from agricultural dust exposure.
| Service | Typical Range in San Martin |
|---|---|
| AC Repair | $150–$650 |
| Furnace Repair | $150–$700 |
| AC Installation | $3,500–$7,500 |
| Tune-Up | $80–$200 |
Propane furnace repairs trend toward the higher end when we need to replace regulators or pressure-test lines. Installations on ranchette properties can exceed the top of range when we’re running new lines to detached structures or upsizing ductwork that was never adequate. We quote upfront before starting work. Call (844) 560-6978 for your exact number — estimates are free.

FAQs — Emergency & Commercial HVAC in San Martin
Propane systems require technicians to verify fuel source, tank access, and propane pressure before any repair or installation — steps unnecessary with natural gas. San Martin’s large share of propane-fired furnaces, due to properties sitting outside PG&E’s gas distribution, means every emergency call here starts with confirming the tank isn’t empty and the regulator isn’t frozen. Call (844) 560-6978 and we’ll walk through it over the phone before dispatching.
Twice yearly: once before spring planting season and again before fall garlic harvest. The agricultural dust here clogs coils faster than urban environments. During a spring harvest emergency call on Bailey Avenue, we found a rooftop unit on a detached workshop completely locked up because the outdoor condenser coil was caked with garlic-field dust. We cleaned the coil, replaced the clogged filter, and reinstalled the unit with a fine-mesh pre-filter to reduce future particulate load — a fix that would be overkill in an urban zip code but essential here.
High head pressure from dirty condenser coils is the most common cause, followed by undersized electrical service to detached buildings. San Martin’s 100°F+ peaks push systems past design limits when coils can’t reject heat. We measure amp draw, clean coils, and check if your electrical panel can handle the locked-rotor amps your compressor demands on restart. Call (844) 560-6978 for diagnostic pricing — we’ll pinpoint whether it’s a maintenance issue or an electrical upgrade.
Yes. These structures are common on San Martin’s 1–5 acre parcels and frequently have independent systems we service. We carry common rooftop unit parts and understand the electrical and propane routing challenges of outbuilding installations. Marcus Feldman has personally diagnosed emergency failures in horse barns, equipment shops, and guest cottages across 95046.
We service all nine major brands in our coverage: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For San Martin commercial clients, we most commonly encounter Trane and Lennox rooftop units on winery and agricultural buildings, with Goodman and Rheem frequent in residential-detached workshop applications. Parts availability is same-day or next-day for all nine.
