Call (877) 454-5066

We’re Meridian Heating & Air, and we’ve been driving out to Highland from our Los Angeles base for years. We know the 92346 zip well — the mid-century tracts near Highland Avenue, the newer builds climbing toward the foothills in East Highland, the way the San Bernardino Mountains cast their shadow over this city while trapping heat in those unconditioned attics. Anthony Moreno, our founder and lead installer, still carries his tools on every job. When you call (877) 454-5066, you’re not getting dispatched to a subcontractor. You’re getting nearly two decades of hands-on HVAC experience, and a crew that understands why Highland’s elevation and wildfire exposure make AC work here different from flatland San Bernardino.

Why Meridian Heating & Air Los Angeles Is Highland’s Preferred AC Repair & Installation Company

Our reputation in Highland is built on showing up when the mountain weather turns. We’ve got 286 customer reviews averaging 4.8 stars, and a fair share of those come from Highland homeowners who found us after a franchise chain sent a technician who’d never heard of the Santa Ana wind effect on refrigerant pressures.

Anthony shows up on the job. That’s not a slogan — it’s how we operate. On a recent compressor replacement near Base Line and Arden Avenue, the homeowner told us the previous company sent three different techs across two weeks, none of whom could explain why the unit kept failing. Anthony diagnosed the short-cycling pattern in twenty minutes, traced it to heat-soaked attic ductwork, and sized a two-stage replacement that actually matched the house.

We work on your brand. Our experience spans nine major manufacturers — Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard — so we’re not pushing whatever’s in the warehouse. For Highland’s older housing stock, that matters. We’ve sourced hard-to-find parts for 1980s Rheem condensers and retrofitted modern filtration onto legacy York systems that still have plenty of life left.

From routine tune-ups to emergency calls, we’re structured for the full spectrum. Summer highs in Highland crack 105°F. Winter nights drop below freezing. Your system works hard at both ends, and we’re equipped for both.

Our AC Repair & Installation Services in Highland

AC Repair

Highland’s diurnal temperature swings — 30°F or more on a typical summer day — punish compressors. The morning starts cool, the unit barely runs, then afternoon hits and the compressor fires hard, overheats, and shuts down on thermal lockout. We see this pattern constantly in the 1970s tracts between Highland Avenue and Boulder Street. Our AC Repair & Installation crew diagnoses the root cause, not just the symptom. A failed capacitor might cost $150–$350 to replace. But if short-cycling has already damaged the compressor, we’ll tell you straight and show you the amp draw readings.

AC Installation

New installations in Highland demand proper Manual J load calculations that account for elevation, solar exposure, and those extreme attic temperatures. The old rule-of-thumb method — one ton per 500 square feet — fails here. We’ve found 1990s East Highland homes with 3-ton units gasping to cool 2,200 square feet because the original builder underestimated heat gain through those west-facing foothill windows. Our installations start with measurement, not assumption. Single-stage systems run $3,500–$7,500; two-stage upgrades for the mountain climate typically add $800–$1,500.

AC Replacement

Replacement decisions in Highland hinge on one question: how much of your cooled air is leaking into the attic before it reaches your vents? In those mid-1960s to late-1980s homes with original ductwork, we regularly measure 20–30% loss. Replacing the condenser alone won’t fix that. Anthony has walked homeowners through the math: a new 16-SEER unit with leaky ducts performs like a 12-SEER with tight ones. Sometimes we recommend duct sealing alongside equipment replacement. Sometimes the ducts are too far gone. We’ll show you the blower-door numbers and let you decide.

Refrigerant Recharge

Refrigerant leaks in Highland often hide through summer, then announce themselves brutally. The system runs just hard enough to maintain on 95°F days. Then an October Santa Ana spike hits 102°F, the compressor can’t keep up, and the house warms fast. We use electronic leak detection and nitrogen pressure testing — not just a top-off that’ll leave you sweating again in three weeks. Recharges run $200–$500 depending on refrigerant type and leak severity; R-22 systems (common in pre-2010 Highland installs) carry higher costs due to phased-out supply.

Compressor Repair

Compressor replacement is our deepest repair category in Highland, and it’s almost always elevation-related stress. Those daily thermal cycles expand and contract internal components until the motor binds or the valves fail. We’ve replaced compressors on 8-year-old units that should have lasted 15, all because the original installer didn’t account for Highland’s aggressive short-cycling environment. Compressor repairs run $700–$2,000. When we quote this, we also check your start kit, capacitor, and contactor — because a weak electrical side will kill the new compressor just as fast.

Trusted Brands We Service in Highland

We carry parts and factory training for Goodman, Rheem, York, and Daikin — four brands we see constantly in Highland’s housing stock. Goodman units dominate the 1990s–2000s East Highland builds; Rheem and York appear throughout the mid-century core; Daikin mini-splits are increasingly common in foothill additions where duct extension isn’t practical. Our van stocks capacitors, contactors, and hard-start kits for these lines specifically, which means faster turnaround for Highland customers. No waiting three days for a San Bernardino warehouse transfer while your attic hits 140°F.

Common AC Repair & Installation Problems We See in Highland Homes

• Compressor failure from short-cycling during 30°F+ diurnal swings. Highland’s elevation creates morning-afternoon temperature gaps that stress single-stage compressors. The unit overshoots setpoint in cool morning air, shuts off, then can’t catch up when afternoon hits. We see this kill compressors in 7–10 years instead of 15.
• Leaky ducts in unconditioned attics wasting 20–30% of cooled air. Those original 1960s–1980s flex duct runs have degraded seals and collapsed insulation. Your replacement AC gets oversized to compensate, which worsens humidity control and short-cycles even harder.
• Refrigerant leaks undetected through summer, exposed by Santa Ana fall spikes. The system limps along at partial charge until an October 98°F day demands full capacity. The compressor overheats, the thermal switch trips, and you’re calling at 10 PM wondering why it worked fine in August.
• Undersized original equipment in 1990s–2000s East Highland homes. Builders spec’d for square footage without adjusting for foothill solar load, larger windows, and higher ceilings. The 3-ton unit runs continuously, never reaches setpoint, and burns out prematurely.
