We’ve been making the climb to Big Bear Lake for nearly two decades. Anthony Moreno, our founder and lead installer, knows the difference between a standard valley repair and the altitude-specific work this mountain demands. At 6,752 feet, your HVAC system isn’t just fighting temperature — it’s fighting thin air, propane conversion requirements, and the deferred maintenance that piles up in second homes sitting empty through the off-season.
Why Meridian Heating & Air Los Angeles Is Big Bear Lake’s Preferred AC Repair & Installation Company
Our 286 verified reviews averaging 4.8 stars include plenty from Big Bear Lake homeowners who found us after franchise techs turned around at the base of the mountain. They come back because Anthony shows up on the job — not a rotating subcontractor who needs GPS to find Snow Summit.
Nineteen years in the HVAC trade means we’ve worked on the exact 1950s–1980s wood-frame cabins and A-frames that dominate Big Bear Lake’s housing stock. We know which crawl spaces have zero insulation, which vacation rentals have been cold-started by well-meaning property managers, and which Goodman or Rheem units up on Summit Boulevard are running on propane with standard sea-level orifices.
We carry LP conversion kits and combustion-analysis tools on every truck. A call that looks like a routine tune-up in Redlands becomes a manifold-pressure and altitude-deration job the moment we’re working at 6,700 feet. That’s not a sales pitch — it’s the reality of mountain HVAC.
Our AC Repair & Installation Services in Big Bear Lake
AC Repair
Summer in Big Bear Lake is mild — highs rarely break the low 80s — so when your cooling system fails, it’s often during a heat wave when every rental unit is packed and every local tech is slammed. We repair all major brands including Trane, Lennox, Goodman, and Rheem, and we stock capacitors and contactors for the common cold-start failures we see in second-home systems that sat idle for months. A typical AC repair in Big Bear Lake runs $175–$765.
AC Installation
New AC installation in Big Bear Lake demands careful load calculation. The altitude reduces air density, which affects both cooling capacity and heat pump efficiency. We size systems for your actual conditions — not a sea-level Manual J run by someone in San Bernardino. Our installations range from $4,130–$8,850, and Anthony personally leads every job.
AC Replacement
Big Bear Lake’s vacation cabins often have original AC units from the 1980s or 1990s, patched together with universal parts and crossed fingers. When replacement makes more sense than another band-aid, we evaluate your ductwork, insulation, and usage patterns. Many mountain homes benefit from heat pump conversion, but only if the unit is rated for low-temperature operation at altitude. We’ll tell you straight if your existing ductwork can handle it or if you’re better staying with a conventional split system.
Refrigerant Recharge
Refrigerant leaks are common in Big Bear Lake systems that cycle on and off seasonally. The thermal expansion and contraction of copper lines in uninsulated crawl spaces accelerates wear at flare fittings and braze joints. We don’t just top off — we leak-test with electronic detectors and nitrogen pressure tests, then repair the source. A recharge without finding the leak is throwing money into the mountain air.
Capacitor Replacement
Capacitors fail more frequently in Big Bear Lake’s cold-start conditions. A system that sits idle for three months, then gets kicked on by a property manager in June, often blows its start capacitor on the first cycle. We carry dual-rated run/start capacitors for all major brands and can usually swap one same-day.
Compressor Repair
Compressor failures in Big Bear Lake often trace back to low refrigerant charge, dirty condensers clogged with pine needles, or repeated hard starts from weak capacitors. We’ll diagnose whether it’s a electrical issue, mechanical seizure, or refrigerant flood-back — and we’ll tell you honestly if repair is worth it versus replacement.

Common AC Repair & Installation Problems We See in Big Bear Lake Homes
- Altitude-derated furnaces causing short-cycling. A standard sea-level furnace installed in Big Bear Lake without proper deration loses roughly 19% effective capacity. It fires, overheats quickly, shuts down on high-limit, and repeats until the heat exchanger cracks or the homeowner calls us in a panic.
- Propane systems running rich and sooting up. When a natural gas unit is converted to propane without altitude-specific orifice sizing, the flame starves for oxygen at 6,700 feet. Soot builds on the heat exchanger, rollout switches trip, and carbon monoxide risk rises.
- Cold-start failures in vacant second homes. That cabin on Bear Boulevard sat fine through March. Now it’s June, the property manager flipped the thermostat, and nothing happens. Capacitor died over winter. Refrigerant leaked through a rusted line set. Compressor seized from sitting in −10°F oil. We see it constantly.
- Undersized heat pumps hitting low-temperature cutoffs. Homeowners install standard heat pumps that work fine in Yucaipa but lock out on Big Bear Lake’s first November night. We specify cold-climate heat pumps with enhanced vapor injection or recommend hybrid systems for true mountain conditions.

FAQs — AC Repair & Installation in Big Bear Lake
Short-cycling at altitude almost always means your furnace wasn’t properly derated for 6,752 feet. Standard sea-level manifold pressure settings deliver too much fuel for the available oxygen, causing the heat exchanger to overheat and the high-limit switch to shut it down. We fix this with combustion analysis, orifice resizing, and manifold pressure adjustment to altitude specs. Call (877) 454-5066 before that cycling cracks your heat exchanger.
Yes, but it requires more than a generic conversion kit. At Big Bear Lake’s elevation, the LP orifices must be sized smaller than standard conversion charts specify, and manifold pressure must be adjusted downward to account for the ~19% combustion efficiency loss. We carry altitude-rated LP kits and verify with digital combustion analysis. Never attempt this with off-the-shelf parts — an improper conversion produces carbon monoxide and voids your warranty.
Deferred maintenance on idle systems. Capacitors degrade in cold storage. Refrigerant migrates to the coldest part of the system and leaks through corroded flare nuts. Condensate lines freeze and crack. We do pre-season inspections specifically for second-home owners in the 92315 ZIP code, catching these failures before your first rental booking. Call us in October, not the night before Thanksgiving.
For cooling alone, probably neither — Big Bear Lake’s summer highs rarely stress a home. But if you’re replacing a furnace and want year-round efficiency, a cold-climate heat pump rated for low-temperature operation at altitude can handle heating down to single digits. Standard heat pumps will lock out and leave you with electric backup strips burning money. We’ll size it honestly for your actual usage, not upsell you on technology you don’t need.
Don’t just flip the switch. After extended shutdown, we inspect the heat exchanger for rust or cracks, verify the ignitor or pilot assembly, check gas pressure with a manometer, and run combustion analysis before declaring it safe. For propane systems, we also verify tank level, regulator function, and line integrity — rodents love chewing flexible gas lines in crawl spaces. This isn’t a DIY procedure. Call (877) 454-5066 and we’ll walk you through what we find.
