We’ve been driving down to East Palo Alto from Sacramento for 16 years, and the jobs here are different from anywhere else on the Peninsula. Where Palo Alto and Menlo Park have largely modernized their housing, East Palo Alto still has hundreds of post-WWII tract homes built between the 1940s and 1960s, many with original floor furnaces and no ductwork at all. Jason Trent, our owner and Field Supervisor, has supervised countless installs in EPA, and our technicians know the specific challenges: cramped crawl spaces, zero existing infrastructure, and the sudden heat spikes that roll in with Diablo winds off the Bay.
Why Stonegate Heating & Air California Is East Palo Alto’s Preferred AC Repair & Installation Company
East Palo Alto homeowners don’t want a dispatcher in a call center. They want someone who’ll show up, diagnose the problem correctly, and stand behind the work. That’s why Jason Trent still works as Field Supervisor, not a back-office owner. He’s on job sites, checking installs, making sure the details are right.
Our numbers back this up. Sixteen years in business. Nearly 500 verified customer reviews averaging 4.7 stars. That volume matters. It means we’ve handled the exact situation you’re dealing with — probably more than once. Whether it’s a failed compressor on a 20-year-old Carrier in the Gardens neighborhood or a first-time mini-split install on a Bay Road bungalow, we’ve done it.
We’re familiar with EPA’s specific conditions. The marine layer keeps things mild most summers, but when Diablo winds shut it off, temperatures can jump 15–20°F in hours. Homes with no cooling become dangerous fast, especially for elderly residents and young children. We keep emergency HVAC availability open because we’ve seen what those sudden spikes do to a household with zero preparation.
Our AC Repair & Installation Services in East Palo Alto
AC Repair
Most AC repair calls we get from East Palo Alto aren’t actually AC repair calls in the traditional sense. They’re from homeowners who’ve added a window unit or portable system that’s failing, or from residents in newer developments off University Avenue with actual central systems that need compressor or capacitor work. A typical AC repair in East Palo Alto runs $150–$650. Capacitor replacements sit at the lower end; compressor repairs push toward the higher range. We stock capacitors and contactors for Carrier, Trane, Lennox, and Goodman systems, so most same-day fixes are possible.
AC Installation
This is where East Palo Alto diverges sharply from neighboring cities. In Palo Alto, we’re usually replacing an existing system. In EPA, we’re often installing cooling for the first time. The city’s housing stock — small 900–1,400 sq ft post-WWII homes, many with original floor furnaces and zero duct infrastructure — makes forced-air retrofits cost-prohibitive. Ductless mini-splits are the practical path. Our AC Repair & Installation team designs zoned systems that don’t require tearing open walls or running duct through crawl spaces that weren’t built for it. Installation ranges from $3,500–$7,500 depending on zones, electrical upgrades, and whether we’re also addressing a condemned floor furnace.
AC Replacement
Full AC replacement in East Palo Alto usually means one of two scenarios: replacing an aging window-unit setup with a proper mini-split system, or upgrading an early 2000s central install in one of the city’s newer developments. We handle both. For the ductless homes, we often pair replacement with removal of the old floor furnace, especially when our inspection reveals a cracked heat exchanger venting combustion gases into living spaces with no CO detector present. That’s not hypothetical. We condemned a unit exactly like this on Bay Road last year.
Refrigerant Recharge
Low refrigerant means a leak, period. We don’t just top off and leave. Our EPA-certified technicians locate the leak, repair it, then recharge to manufacturer spec. In East Palo Alto’s salt-air environment near Ravenswood Slough, outdoor coil corrosion is more common than inland, and micro-leaks develop faster. A recharge with leak repair typically falls in the $150–$650 repair range. We’ll show you the pressure readings before and after.

Trusted Brands We Service in East Palo Alto
We carry factory training or direct experience on nine major HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For East Palo Alto’s mini-split-heavy market, we stock Daikin and Lennox ductless components locally, plus universal fit parts for Goodman and Rheem systems. That means faster turnaround. You’re not waiting three days for a control board while your house hits 95°F during the next Diablo wind event. Whatever brand you have, we service it. No “we don’t work on that” dead ends.
Common AC Repair & Installation Problems We See in East Palo Alto Homes
- Cracked heat exchangers in original floor furnaces. These 1950s–1960s units still run in EPA homes, and the heat exchanger metal fatigues after 60+ years of thermal cycling. A crack vents carbon monoxide directly into living spaces. We find these regularly, and the only safe move is full condemnation and replacement.
- Zero duct infrastructure making central AC retrofits impractical. Adding forced-air to a home built without ducts means either major structural work or accepting severely compromised efficiency. Most EPA homeowners choose ductless mini-splits instead, but many don’t realize this until they’ve gotten a shocking retrofit quote elsewhere.
- Corroded outdoor coils from Bay-edge salt air. East Palo Alto’s proximity to Ravenswood Slough and the Bay accelerates coil degradation. Micro-leaks develop, efficiency drops, and eventually the system fails entirely. Annual tune-ups catch this early.
- Diablo wind heat spikes overwhelming homes with no cooling. When offshore flow shuts off the marine layer, temperatures jump fast. Homes that never needed AC suddenly become unlivable, and we get emergency calls from residents who’ve never owned a cooling system and don’t know where to start.

FAQs — AC Repair & Installation in East Palo Alto
East Palo Alto’s post-WWII tract homes were built without ductwork on the assumption that Bay-edge marine air kept conditions tolerable year-round. Builders in the 1940s–1960s simply didn’t design for cooling, and the cooler, foggier microclimate near Ravenswood Slough reinforced that choice. Call (855) 467-1888 and we’ll walk you through practical retrofit options for your specific home.
A cracked heat exchanger is an immediate safety hazard that requires furnace condemnation and replacement. The crack allows combustion gases, including carbon monoxide, to enter living spaces directly, and many EPA homes have no CO detection installed. We find these regularly in 1950s–1960s floor furnaces still in daily use. If you have an original furnace, call (855) 467-1888 for a safety inspection.
You can, but it’s often not cost-effective. Adding ductwork to a home built without it requires major structural modification, and the small square footage of most EPA homes (900–1,400 sq ft) makes the per-square-foot cost disproportionately high. Ductless mini-splits are the standard solution we recommend for East Palo Alto’s housing stock. Call for a free assessment of your specific layout.
We install Daikin, Lennox, and Carrier mini-split systems in East Palo Alto, with Daikin being our most common choice for multi-zone EPA retrofits due to compact outdoor units and strong cold-weather heat pump performance. All three brands integrate with existing electrical where possible. We’ll recommend based on your home’s layout and your heating-cooling priorities.
Diablo winds are offshore, dry winds that shut off East Palo Alto’s normal marine layer cooling. When that flow stops, the fog dissipates, and temperatures can rise 15–20°F within hours. EPA’s homes, built without cooling, have no thermal buffer against these sudden shifts. Emergency HVAC availability matters here because these events are unpredictable and can create dangerous indoor conditions for vulnerable residents. Call (855) 467-1888 if you need rapid response during a heat event.
