Fast, Reliable AC Repair & Installation Across Berkeley
AC repair in Berkeley typically runs $150–$650, while a new AC installation costs $3,500–$7,500. Most repairs are completed same-day, and our AC Repair & Installation team regularly dispatches to Berkeley from our San Jose base.
We’ve been driving up to Berkeley for nearly two decades now, and we’ve learned that this city breaks every rule that works in San Jose. The pre-war bungalows in the flatlands, the 1990s hillside rebuilds, the carved-up student rentals near UC Berkeley — each demands a completely different approach. Owner Marcus Feldman still manages every job personally, so when you call Crestview Heating & Air California at (844) 560-6978, you’re talking to someone who’ll actually show up. Not a dispatcher reading from a script.
Why Crestview Heating & Air California Is Berkeley’s Preferred AC Repair & Installation Company
Berkeley customers have left us enough reviews to push our average to 4.8 stars across 250+ total. That’s not a handful of cherry-picked testimonials — it’s a track record built one appointment at a time.
What Berkeley homeowners tell us they value most: Marcus Feldman answers the phone, manages the schedule, and still carries a tool bag. There’s no franchise layer, no outsourced call center, no technician who changes month to month. When we return to a home on Dwight Way or in the Elmwood, we remember the house. We remember the plaster walls. We remember whether the last job was a capacitor replacement on a 1980s Carrier or a first-ever mini-split in a Brown Shingle.
Our familiarity with Berkeley’s specific conditions matters. The marine layer, the Diablo winds, the unpermitted rental conversions — these aren’t abstract concepts to us. They’re the actual conditions we plan for. That 10–15°F temperature swing between flatland and hill can make or break a load calculation. We’ve seen contractors from outside the East Bay apply one formula to the whole city and install equipment that can’t handle a 100°F afternoon in the flats while the hills are still wrapped in fog.
Our AC Repair & Installation Services in Berkeley
AC Repair
Berkeley’s AC repair calls spike on two predictable occasions: first Diablo wind event of summer, and first week of September when the marine layer finally breaks. We see a lot of capacitor failures on aging systems that ran fine in San Jose’s drier heat but struggle with Berkeley’s humidity swings. Compressor issues are common too, especially on units that were oversized for the space and short-cycle through foggy mornings. Our repair range is $150–$650, and we stock capacitors and contactors for Trane, Lennox, Goodman, and Rheem to avoid delay.
AC Installation
Here’s the reality in Berkeley: most homes in ZIPs 94702 through 94705 were built before 1940 with floor furnaces, wall heaters, or gravity systems. Zero ductwork. Zero provision for cooling. Installing AC here usually means designing a ductless mini-split system from scratch, and that’s become the defining skill of our local trade. We recently retrofitted a 1923 Brown Shingle in the Southside (94704) with a ductless mini-split system. The owner had a failing floor furnace that couldn’t keep up with summer heat events, and plaster walls made traditional ductwork impossible. We installed a Daikin mini-split, preserving the home’s historic character while providing efficient cooling. Installation runs $3,500–$7,500 depending on zones and electrical upgrades.
AC Replacement
Replacement jobs in Berkeley often involve removing a window unit or through-wall sleeve that someone’s limped along with for fifteen years. The hills have more 1990s rebuilds with existing ductwork from post-Tunnel Fire construction, but even those systems are hitting end-of-life. We handle refrigerant recovery, permit coordination, and proper disposal — Berkeley’s inspectors are thorough, and we don’t cut corners that would fail a final.
Refrigerant Recharge
Low refrigerant in Berkeley usually means a leak, not normal depletion. The coastal air’s salt content accelerates coil corrosion on outdoor units, especially in the fog-persistent hills. We locate and repair leaks before recharging — it’s illegal to top off R-22 or R-410A knowing it’ll vent again, and it’s not how we operate.

Trusted Brands We Service in Berkeley
We service nine major brands — Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard — and we keep common parts in stock for Berkeley calls. That means faster turnaround when your Lennox compressor fails on a Friday evening or your Goodman capacitor gives out during a heat event. We’re factory-trained across all nine, so “we don’t work on that” isn’t something you’ll hear from us. Your system, our specialty.
Common AC Repair & Installation Problems We See in Berkeley Homes
- Undersized mini-splits in the Berkeley Hills. Installing a single-zone mini-split in a Berkeley Hills home (94707) that loses cooling capacity because the marine layer traps fog, leading to undersized equipment. Contractors who don’t account for latent load from persistent moisture end up with unhappy customers and callbacks.
- Disconnected flue venting in Southside rentals. During a permitted heat pump conversion in a Southside rental (94704), discovering disconnected flue venting on a wall furnace — an unpermitted modification that stops the project mid-job. Berkeley’s inspectors flag this actively, and we’ve learned to inspect thoroughly before quoting.
- Load calculation failures across microclimates. Applying the same load calculation to a flatland bungalow (94702) and a hillside rebuild (94708) on a Diablo wind day, causing dramatic undersizing or oversizing due to the 10–15°F intra-city temperature swing. We’ve replaced systems that were installed with San Jose assumptions.
- Plaster wall damage from improper mini-split mounting. Pre-1940 Brown Shingles and Craftsmans have lath-and-plaster walls that crumble if you don’t know where to drill. We’ve cleaned up after contractors who treated Berkeley walls like modern drywall.

FAQs — AC Repair & Installation in Berkeley
Yes, and ductless mini-splits are specifically designed for this situation. Most of our Berkeley installations in pre-1940 homes are first-ever cooling systems using wall-mounted or ceiling-cassette mini-splits with no ductwork required. We recently completed exactly this type of installation in a 1923 Brown Shingle in Southside Berkeley. Call (844) 560-6978 for a free estimate on your specific layout.
No, but Berkeley’s Reach Code heavily incentivizes all-electric systems and the city was the first in the U.S. to attempt a new-construction natural gas ban. For retrofits, heat pumps are often the practical choice because they provide both heating and cooling in one system, and rebates can offset higher upfront costs. We can explain what’s currently available for your project.
Yes, the persistent fog and marine layer in 94708 and 94709 create latent load that standard cooling-only calculations often miss. Proper mini-split sizing must account for moisture removal, not just temperature drop. We’ve replaced undersized systems in the hills that couldn’t keep up on foggy August mornings.
Repair the furnace if you only need heat and it’s a simple fix under $400. Install a heat pump or mini-split if you want cooling too, if the furnace needs major parts that are obsolete, or if Berkeley’s electrification incentives make conversion cost-effective. Most wall furnaces in Berkeley rentals have unpermitted modifications that complicate either path — we’ll inspect before quoting.
Yes, Berkeley requires permits for all new HVAC installations and actively inspects heat pump conversions for code compliance, including proper venting and electrical work. We handle permit submission and scheduling as part of our installation process. The city’s inspectors are thorough but fair if the work is done correctly.
