Fast, Reliable AC Repair & Installation Across Crestline
AC repair in Crestline runs $150–$650 for most jobs, and same-day service is available when you call (855) 467-1888. We’re Stonegate Heating & Air California, and our AC Repair & Installation team makes the climb up Highway 18 to Crestline regularly — we know the mountain roads, the propane-only fuel situation, and the quirks of 1950s–1970s cabins that were never built for central air.
Jason Trent, our owner and Field Supervisor, has spent 16 years working California HVAC systems from Sacramento down to the San Bernardino Mountains. Crestline isn’t an afterthought for us. We stock propane orifice kits, we build elevated condenser stands for snow country, and we know that a system spec’d for San Bernardino will fail here at 4,500 feet. Whether you’re on Lake Drive, along Crest Forest Drive, or up near Valley of Enchantment, we come prepared for altitude deration and freeze-thaw cycles the valley techs never see.
Why Stonegate Heating & Air California Is Crestline’s Preferred AC Repair & Installation Company
Our 499 verified reviews average 4.7 stars across platforms, and Crestline customers specifically mention the same thing: Jason shows up, not some rotating subcontractor. Owner on the job means the person quoting the work is the person making sure it’s done right. In a town where a misaligned propane orifice can soot up a heat exchanger in a single season, that accountability matters.
We carry parts for Carrier, Bryant, and American Standard on our trucks, plus universal propane conversion kits for the brands that don’t factory-ship mountain-ready units. That stockpile cuts wait times for Crestline homeowners who’ve already been told “we’ll have to order that” by flatland companies.
Our response time to Crestline averages same-day to next-day for non-emergencies, and we prioritize calls where a vacation home has gone sub-freezing with a failed wall furnace or burst refrigerant lines. We know which cabins on Lake Drive are full-time and which sit empty for weeks. That local pattern recognition saves you from repeat failures.
Our AC Repair & Installation Services in Crestline
AC Repair
Most Crestline AC repair calls we get aren’t actually cooling emergencies — they’re homeowners who fired up a neglected system for a rare hot August afternoon and found weak airflow or no cold air. Common culprits: refrigerant leaks from corrosion, failed capacitors after winter dormancy, or compressor issues in R-22 systems that should’ve been retired years ago. We diagnose before we quote. Repairs run $150–$650.
AC Installation
New AC installation in Crestline demands propane-ready equipment, correct altitude deration, and outdoor units elevated above snow line. We recently replaced a failing 1970s Carrier condenser at a cabin on Lake Drive, where the original R-22 system had corroded beyond repair due to snowmelt. We retrofitted a new Goodman propane-ready unit elevated on a custom stand to prevent ice damming, a typical Crestline job. Installations range $3,500–$7,500 depending on whether we’re retrofitting ductwork into a 1960s A-frame or dropping into an existing forced-air system.
AC Replacement
Replacement season in Crestline often follows a freeze-damage event: a vacation home’s propane runs out, the wall furnace dies, and the owner decides it’s finally time for central HVAC that handles both heating and cooling. We size these systems for the dominant heating load — Crestline’s heating demand overwhelms its modest cooling need — and we spec propane orifices, not natural gas conversions that’ll soot up within a month. Undersized retrofits from flatland contractors are a recurring problem we fix.
Refrigerant Recharge
R-22 systems are still common in Crestline’s older cabin stock. We recharge where it makes sense, but we’re direct about when you’re throwing money at a leaking system that can’t be legally manufactured anymore. For newer R-410A or R-32 systems, we pressure-test, locate leaks with electronic detection, and recharge with the correct charge weight for your elevation — another number valley techs often get wrong.
Capacitor Replacement
Capacitors fail hard after Crestline winters. The thermal cycling from below-freezing nights to occasional 80-degree days stresses start and run capacitors more than steady-climate regions. We stock dual-rated capacitors for the brands we see most, and we check contactor condition while we’re in there — pitted contacts cause the same voltage drop that kills capacitors prematurely.
Compressor Repair
Compressor failure in Crestline usually traces to one of three causes: improper propane orifice sizing causing high head pressures, low refrigerant charge from undetected leaks, or outdoor units sitting in snow that blocks airflow and overheats the condenser. We don’t just swap compressors. We find out why it failed, because a new compressor in a system with chronically low charge or blocked airflow dies the same way. That’s the difference between a repair and a band-aid.

Trusted Brands We Service in Crestline
We’re factory-trained or field-experienced on nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Crestline specifically, we keep propane conversion parts for Carrier and Bryant systems in stock, plus universal orifice kits for Goodman units that ship natural-gas default. Daikin’s mini-split lines work well for Crestline’s smaller cabins where ducted retrofits aren’t practical. Whatever brand you have, we don’t punt to “call the manufacturer.” We fix it.
Common AC Repair & Installation Problems We See in Crestline Homes
- Propane orifice kits misaligned after installation. A technician used to San Bernardino’s natural gas mains installs a standard orifice, doesn’t check manifold pressure, and the flame rolls out or soots the heat exchanger. We see this on warranty-call follow-ups from other companies. Crestline’s propane-only fuel supply demands specific orifice sizing and regulator pressure that flatland techs rarely handle.
- Condenser units placed too low, leading to ice damage. Snow accumulation around a ground-level condenser melts, refreezes, and warps coils or cracks copper. We build elevated stands as standard practice on Crestline installs, not as an upsell. It’s basic mountain-country HVAC.
- Older cabins with undersized ductwork causing refrigerant or airflow imbalances. A 1960s A-frame retrofitted with a forced-air system designed for a 1,200-square-foot tract home can’t move enough air through 4-inch walls and odd angles. The compressor short-cycles, the evaporator ices, and the homeowner thinks they need a bigger unit. Usually they need correct duct sizing or a ductless solution.
- Freeze-damage triage in vacant vacation homes. A large share of Crestline properties are part-time residences that go unoccupied for weeks. When the propane runs out or a thermocouple fails on an aging wall furnace, the home drops below freezing before anyone notices. Burst copper, cracked heat exchangers, and refrigerant line ruptures are routine call types here that simply don’t exist in the flatland service area below.

FAQs — AC Repair & Installation in Crestline
No. SoCalGas does not serve Crestline with natural gas mains, so virtually every heating install involves propane, requiring correct orifice sets and regulator pressures that technicians working San Bernardino or Redlands never touch. A “standard” natural gas unit installed here will soot, roll flame, and potentially crack the heat exchanger. We convert and commission every system for propane before we leave. Call (855) 467-1888 if you’re unsure what fuel type your current system uses — we’ll check it.
Snowmelt and freeze-thaw cycles push moisture into the coil fins, where it expands and damages aluminum. Condensers sitting at ground level are especially vulnerable. We prevent this by elevating units on stands and recommending winter covers for seasonal-use homes. If your coils are already damaged, we can pressure-test and repair or quote replacement. The fix is usually mechanical — elevation and drainage — not a bigger unit.
Probably not for cooling alone. Crestline summers rarely exceed the low 80s, and heating demand dominates overwhelmingly. Many locals resist central A/C as an unnecessary upsell. We agree — unless you’re converting a vacation home to year-round use with full ducted heating, a mini-split or even strategic window units often handle the brief hot spells. We’ll tell you if central A/C makes sense for your specific usage pattern, not sell it by default.
Shut off the refrigerant lines at the service valve, drain or insulate any exposed condensate lines, and have us install a winter cover that breathes (trapped moisture rots electrical components). More importantly, maintain your heat source — whether it’s our installed propane furnace or your existing wall heater — because freeze damage from a cold house costs far more than any AC component. We offer seasonal shut-down and restart services for part-time Crestline owners.
Replace, in most Crestline cases. R-22 hasn’t been manufactured since 2020, reclaimed supply is dwindling, and a recharge on a leaking system is money you’ll spend again within a season. Retrofit refrigerants exist but perform poorly in propane systems at altitude. Given Crestline’s older housing stock, we usually find that a new R-410A or R-32 unit with modern controls and proper propane orifices pays back within a few seasons through efficiency and reliability. We’ll give you honest numbers on both paths when we inspect. Call (855) 467-1888 for a free replacement quote.
