Berkeley isn’t like other East Bay cities. The same marine layer that keeps your morning foggy can rust through a commercial rooftop unit in the flatlands, while a few blocks uphill in the Berkeley Hills, a 1990s rebuild might have modern ductwork hiding a cracked heat exchanger from that last winter storm. We’ve worked on both, and everything in between.
Why Crestview Heating & Air California Is Berkeley’s Preferred Emergency & Commercial HVAC Company
Our 4.8-star average across 250+ customer reviews didn’t come from easy jobs. It came from showing up at midnight to a carbon monoxide alarm blaring in a 1920s Brown Shingle on Ward Street, tracing the problem to a cracked gravity floor furnace venting into a sealed crawlspace, and fixing it right. That was Berkeley. That was real.
Marcus Feldman, our owner, still serves as Service Manager. He manages jobs in the field, not from behind a desk. When you call Crestview, you’re getting ownership-level accountability on every visit, not a dispatched contractor you’ve never met.
Our 19 years in HVAC means we’ve seen virtually every system type, age, and brand Berkeley can throw at us. Floor furnaces from the 1920s. Wall heaters with decades of unpermitted flue modifications. Heat pumps installed last year under the city’s electrification push. Your system, our specialty.
We know the ZIPs: 94710, 94712, 94720, 94701, and the surrounding flatland and hill neighborhoods. We know that a load calculation for a property on University Avenue won’t work for a house on Grizzly Peak Boulevard, and we size accordingly.
Our Emergency & Commercial HVAC Services in Berkeley
24/7 Emergency HVAC
Berkeley’s pre-1940 housing stock doesn’t fail on a schedule. We responded to that 3 AM no-heat emergency at the 1920s Brown Shingle on Ward Street in 94705. The original gravity floor furnace had a cracked heat exchanger from years of coast fog corrosion, and the flue was venting into a sealed crawlspace. We isolated the gas, installed a carbon monoxide alarm, and replaced the unit with a ductless heat pump the next week. Whether it’s a CO risk in a Southside rental or a complete system failure during a Diablo wind event, our emergency team is available when Berkeley needs us.

Commercial HVAC
Commercial buildings along San Pablo Avenue and in the Downtown corridor face a specific enemy: marine layer salt air. Pre-1940s flatland structures with rooftop units see accelerated corrosion that city contractors from inland markets often underestimate. We’ve replaced rusted-out commercial package units that failed precisely when Berkeley’s temperatures spiked into the 90s, because the marine layer retreated and the Diablo winds hit. Our commercial work includes proper sizing for Berkeley’s microclimates, not generic calculations.

Rooftop Unit Service
Rooftop units in Berkeley take a beating that manuals written for Phoenix don’t anticipate. Salt air from the Bay, fog persistence in the hills, and the thermal shock of rapid temperature swings when the marine layer burns off. We service and replace commercial rooftop units across the flatland ZIPs, with factory-trained compatibility across Trane, Lennox, Goodman, and Rheem systems. When a rooftop unit fails on your commercial property, we diagnose whether it’s a repair or replacement, and we don’t push equipment you don’t need.

Chiller Service
While less common in Berkeley’s smaller commercial footprint, chillers serve critical roles in UC Berkeley-adjacent research facilities and larger multi-use buildings. Our team handles chiller diagnostics, refrigerant management, and efficiency optimization. Given Berkeley’s electrification policies and rising cooling demands, maintaining existing chiller efficiency often beats replacement for both cost and environmental impact.

HVAC Inspection
Annual inspections in Berkeley aren’t a checkbox exercise. In the flatlands, we check for disconnected flue vents on original wall furnaces, a code and safety issue that Berkeley inspectors actively flag during any permitted heat pump conversion. In the Hills, we look for heat exchanger cracks in 1990s Tunnel Fire rebuilds that can go silent until they become dangerous. Our inspections include mold-prevention assessment in fog-heavy hill zones where dehumidification matters.

Trusted Brands We Service in Berkeley
We service nine major HVAC brands, and we keep common parts in stock for Berkeley’s most frequent calls. That means Trane, Lennox, Goodman, and Rheem systems get faster turnaround, whether it’s a residential heat pump in a Northside bungalow or a commercial package unit on Telegraph Avenue. We’ve factory-trained on Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard, so Berkeley customers are never told “we don’t work on that.” From emergency repairs to full replacements under the city’s electrification incentives, your equipment is covered.
Common Emergency & Commercial HVAC Problems We See in Berkeley Homes
- Cracked heat exchangers in original floor furnaces. Berkeley’s flatlands are dense with pre-1940s craftsman bungalows and Brown Shingle multi-units with gravity floor furnaces. Coast fog corrosion weakens metal over decades, and the first sign is often a carbon monoxide alarm or a faint gas odor. These are emergency calls we take seriously.
- Disconnected flue vents from unpermitted conversions. UC Berkeley’s rental-heavy Southside and Downtown corridors have older buildings carved into apartments without permit-tracked HVAC changes. We routinely find mismatched or disconnected flue venting on original wall furnaces. It’s a safety hazard, and it’s why we carry CO detectors on every truck.
- Rusted commercial rooftop units failing on heat wave days. Pre-1940s flatland buildings with rooftop package units see accelerated corrosion from marine layer salt air. They tend to fail when the Diablo winds push temperatures into the 90s and 100s, exactly when cooling is most needed.
- Heat exchanger failures in 1990s Tunnel Fire rebuilds. The Berkeley Hills ZIPs contain rebuilds with modern ductwork but aging original equipment. Heat exchangers crack without warning during winter storms, and the ductwork can mask the problem until it’s severe.
Pricing for Emergency & Commercial HVAC in Berkeley, CA
Honest pricing starts with real numbers. Here’s what Berkeley customers typically pay:
| Service | Typical Range in Berkeley |
|---|---|
| AC Repair | $150–$650 |
| Furnace Repair | $150–$700 |
| AC Installation | $4,130–$8,850 |
| Tune-Up / Inspection | $95–$235 |
Several factors push Berkeley jobs toward the higher or lower end. Ductless mini-split installations in unducted 1920s bungalows require more labor than swap-outs in homes with existing ductwork. Emergency calls outside standard hours carry premium rates. Commercial rooftop access in dense flatland corridors can add rigging complexity. But we quote upfront, before work begins, and estimates are free. Call (844) 560-6978 to schedule yours.

FAQs — Emergency & Commercial HVAC in Berkeley
Unpermitted apartment conversions in UC Berkeley’s rental corridors left original wall and floor furnaces with jury-rigged or completely disconnected flue vents. Decades of undocumented changes mean we regularly find venting that no longer reaches the exterior, creating carbon monoxide risks that require immediate attention. If you smell gas or your CO alarm triggers in a pre-1960s Berkeley rental, exit and call (844) 560-6978 immediately.
Salt-laden marine air accelerates corrosion on commercial rooftop units, particularly on pre-1940s flatland buildings with aging steel cabinets. The damage is often hidden until a Diablo wind heat wave forces the system to full capacity, revealing weakened coils, rusted heat exchangers, or failed compressors. Annual inspections with corrosion checks catch this before emergency failure.
Yes, and it’s increasingly common in Berkeley as electrification policies push homeowners away from gas heating. Ductless mini-splits are the defining retrofit solution for unducted pre-1940s homes, with single or multi-zone configurations that avoid tearing into plaster walls. We design these systems specifically for Berkeley’s load requirements, which differ dramatically between fog-cooled hills and sun-exposed flatlands.
These homes have modern ductwork but often retain original furnaces or heat exchangers now reaching end of service life. The Hills see sharper winter temperature drops than the flatlands, and heat exchanger cracks can go undetected until a storm forces continuous operation. We inspect for cracks, flame rollout, and backdrafting that ductwork alone won’t reveal.
Fog persistence in the Berkeley Hills, particularly in 94708 and 94709, creates sustained humidity that inland markets don’t experience. Commercial systems with poor drainage or clogged condensate lines develop mold in ductwork and air handlers, affecting indoor air quality and system efficiency. Berkeley’s combination of marine moisture and electrification-driven increased cooling loads makes mold prevention a specific local priority.
