We’ve been driving to Hillsborough since 2005. Anthony Moreno, our founder and lead installer, knows the difference between a fog-zone home near El Camino Real and a sun-baked property up toward the Crystal Springs ridge. That local knowledge matters when you’re sizing a system. Hillsborough’s building department operates independently from San Mateo County, with its own permit process and architectural review board. We’ve navigated those requirements for nearly two decades. When your AC fails on a 90°F afternoon in upper Hillsborough, you need a contractor who shows up prepared, not one who learns your town’s rules after they’ve already placed equipment wrong.
Why Meridian Heating & Air Los Angeles Is Hillsborough’s Preferred AC Repair & Installation Company
286 customers and counting have left us reviews averaging 4.8 stars. That track record spans nearly two decades of residential installs, emergency repairs, and commercial service calls. Hillsborough homeowners specifically mention our preparedness in reviews, noting we arrive with the right parts rather than making return trips.
Anthony shows up on the job. On an AC installation, he’s the one handling the brazing, the vacuum test, and the final walkthrough. Not a rotating subcontractor. Not a sales manager who disappears after the contract is signed. This matters in Hillsborough, where a single installation might involve three separate inspections and design-review sign-off for street-facing equipment.
We respond to Hillsborough calls from our Peninsula route schedule. Emergency HVAC service is available for urgent situations, and we stock capacitors, contactors, refrigerant, and compressors for the nine major brands we service. Our familiarity with Hillsborough’s 94010 ZIP code and its microclimates means we don’t guess at load calculations. We measure.
Our AC Repair & Installation Services in Hillsborough
AC Repair
Capacitor failures and refrigerant leaks are the most common calls we get from Hillsborough homes, especially in late summer when older compressors are stressed from cycling on and off. We recently serviced a 1940s Spanish colonial on Ralston Avenue where the original gravity furnace had been patched with mismatched duct runs through a finished attic. The homeowner wanted AC but could not tolerate visible floor registers in the formal dining room. We designed a two-zone system with Carrier high-wall mini-splits concealed above custom cabinetry, running refrigerant lines inside an existing chase to avoid violating the town’s facade review, and passed inspection on the first pass. AC repair in Hillsborough runs $150–$650 depending on the component and accessibility.
AC Installation
New AC installation in Hillsborough demands more than equipment selection. The town’s building department enforces strict architectural review on HVAC equipment placement. Outdoor condensers on street-facing elevations often require screening or ground-mounted locations invisible from the public right-of-way, a constraint not enforced in neighboring San Mateo or Burlingame. We’ve seen contractors pull county permits or place condensers without design-review sign-off, then face stop-work orders on projects already well underway. Anthony handles the permit submittals personally, including equipment location drawings that satisfy Hillsborough’s review board before any concrete pad gets poured. AC installation for Hillsborough estates ranges $3,500–$7,500.
AC Replacement
Many Hillsborough homes still run original forced-air systems from the 1960s or 1970s, with ductwork that snakes through multi-wing floor plans in ways that create pressure imbalances. Replacing the condenser alone won’t fix hot pockets in distant wings. We evaluate the full distribution system, test static pressure, and specify zone dampers where the original design can’t deliver even cooling. For homes with original gravity furnaces, replacement often means reengineering the air handler location to accommodate modern blower specifications without damaging finished spaces. We work on your brand, whether it’s a Rheem, Trane, Lennox, or Goodman system being retired.
Refrigerant Recharge
Low refrigerant in Hillsborough usually signals a leak, not normal consumption. The temperature swings between fog-cooled flats and sun-exposed hillsides cause thermal expansion and contraction in line sets, stressing flare connections and evaporator coils. We perform electronic leak detection before adding any refrigerant, EPA-certified recovery if your system still runs R-22, and document the repair for Hillsborough’s inspection requirements. Recharge costs depend on the refrigerant type and leak location, typically falling within our $150–$650 repair range.

We carry factory-authorized parts and have hands-on experience with Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard.

From routine tune-ups to emergency calls, we work on your brand.
Common AC Repair & Installation Problems We See in Hillsborough Homes
- Condensers placed on street-facing elevations without architectural review approval. Hillsborough’s Town building department will issue a stop-work order, and you’ll pay to relocate equipment that was already set and charged. We submit location drawings before breaking ground.
- Single-zone systems struggling in sprawling multi-wing estates. Hillsborough’s large homes from the 1920s through 1970s weren’t designed for modern forced-air distribution. Zone dampers and separate returns are often necessary to eliminate hot and cold pockets.
- County-standard duct sizing applied to upper-slope homes. Elevation differences within the same Hillsborough block mean load calculations must account for 90°F+ afternoon sun on hilltop lots versus fog-shaded flats near El Camino. Undersized ductwork on a sun-exposed home can’t move enough air.
- Original gravity furnaces with mismatched retrofitted cooling. Many Hillsborough homes have early forced-air additions that snake awkwardly through finished attics. These systems leak pressure, create noise, and often can’t support modern SEER2 equipment without duct replacement.

FAQs — AC Repair & Installation in Hillsborough
Yes. Hillsborough’s Town building department issues its own permits independently from San Mateo County, and most AC installations also require architectural review for equipment placement on street-facing elevations. Anthony handles permit submittals personally, including equipment location drawings, to avoid the stop-work orders we’ve seen contractors receive after pulling county permits or placing condensers without design-review sign-off. Call (877) 454-5066 and we’ll walk you through what’s needed for your specific property.
Yes. We’ve installed concealed high-wall units above custom cabinetry, recessed cassettes in coffered ceilings, and floor-mounted units behind furniture in Hillsborough estates. The key is running refrigerant lines through existing chases or new construction hidden from street view, which also satisfies Hillsborough’s facade review requirements. Our Ralston Avenue project with Carrier high-wall mini-splits passed inspection on the first pass with no visible line sets. Call (877) 454-5066 for a design consultation.
Usually not in a way that’s worth doing. Original gravity warm-air furnaces in Hillsborough homes lack the blower speed and static pressure capability to support modern evaporator coils. The ductwork was sized for gravity convection, not forced-air cooling. We evaluate whether the existing distribution can be adapted, but most 1950s gravity systems require replacement of both the heating and cooling sides to deliver even temperatures. A free on-site assessment will give you real numbers. Call (877) 454-5066.
Hillsborough’s multi-wing floor plans and elevation-driven microclimates create load variations that single-zone systems can’t handle. Upper-slope homes bake in afternoon sun while lower fog-zone parcels rarely need cooling. Ductwork in sprawling estates often lacks returns in distant wings, creating pressure imbalances. We specify zone dampers, additional returns, or supplemental mini-splits based on a room-by-room load calculation. Call (877) 454-5066 to diagnose your specific hot spots.
AC installation for Hillsborough estates typically ranges $3,500–$7,500, with larger homes at the higher end due to multi-zone requirements, architectural review compliance, and duct modifications. Homes over 5,000 square feet with original gravity systems may exceed this range if full duct replacement is needed. We provide exact quotes after evaluating your home’s layout, existing infrastructure, and Hillsborough’s specific permit requirements. Estimates are free. Call (877) 454-5066.
