Crestline isn’t like the cities below the rim. At 4,500 feet in the San Bernardino Mountains, this former vacation-cabin community sees genuine winter — hard freezes, measurable snow, and propane-only heating with no natural gas infrastructure. Thousands of those original A-frames and weekend retreats have become year-round homes, but they were never built for it. We’ve spent nearly two decades retrofitting heat into structures with minimal insulation, unconventional floor plans, and crawl spaces that freeze. Owner Marcus Feldman still manages jobs personally, and that matters when your technician needs to understand altitude de-rating, propane logistics on snow-closed roads, and how to squeeze ductwork or mini-splits into a 1960s cabin built on a steep lot.
Why Crestview Heating & Air California Is Crestline’s Preferred Heating & Furnace Company
Our 4.8-star average across 250+ reviews reflects real jobs in mountain communities like this one. Crestline customers mention the same things: we show up when valley-based companies won’t drive the mountain, we know propane systems, and we don’t treat altitude as an afterthought.
Marcus Feldman isn’t just the owner — he’s the Service Manager on active jobs. That means ownership-level accountability is built into daily operations, not reserved for the sales pitch. When we dispatch to a home off Lake Drive or up toward Skyforest, the same person shaping the estimate is reviewing the combustion analysis.
Nineteen years in HVAC means we’ve worked on virtually every system type, age, and brand a Crestline homeowner could own. Carrier, Trane, Lennox, Goodman, Rheem — we stock parts and factory-trained knowledge across all nine major brands. No one gets told “we don’t work on that.”
Response time to Crestline varies with weather, obviously. But we prioritize mountain calls during cold snaps because we know what’s at stake: frozen pipes, failed propane regulators, and families in homes never designed for full-time winter occupancy. Emergency HVAC service is available when systems fail outside normal hours.
Our Heating & Furnace Services in Crestline
Furnace Repair
Most Crestline furnace repair calls we receive involve propane units that aren’t burning clean. Sometimes it’s a clogged flame sensor or failing ignitor. Often it’s deeper: a valley crew installed the furnace without de-rating for altitude, and now it’s sooting up, short-cycling on high-limit, and running inefficiently. We arrived at an A-frame off Hook Creek Road where the furnace was cycling on limit. The owner had just moved in full-time. Our tech found a clogged flame sensor on a 12-year-old Carrier propane unit, cleaned it, and checked combustion numbers — properly de-rating the manifold pressure for Crestline’s elevation. System fired cleanly and has run fine since. Typical furnace repair in Crestline runs $150–$700 depending on parts and labor.
Furnace Replacement
Replacing a furnace in Crestline means more than swapping boxes. We size for altitude-de-rated output, evaluate whether existing ductwork from a cabin conversion can handle the load, and confirm propane supply sizing — especially critical when snowed-in tanks limit delivery access. Many A-frames here have no ductwork at all, so we also quote mini-split and ducted heat pump alternatives where appropriate. A full furnace replacement with proper Crestline-specific commissioning takes planning you don’t get from a dispatch tech reading a manual for sea-level install. We handle permits, propane line coordination, and post-install combustion verification.
Furnace Tune-Up
Annual furnace tune-ups in Crestline pay for themselves. At $80–$200, this service catches flame sensor degradation, heat exchanger stress cracks, and regulator supply issues before mid-winter failure. We clean burners, check manifold pressure against altitude-corrected specs, test safety limits, and verify thermostat anticipator settings for propane heat. Given Crestline’s hard freezes and the consequences of a dead furnace in a poorly insulated cabin, we recommend preseason tune-ups in early fall before the first mountain snow.
Heat Exchanger Inspection & Replacement
Cracked heat exchangers are a genuine safety issue in propane furnaces, and Crestline’s altitude-de-rating complications can mask the symptoms. A furnace running rich from improper manifold pressure produces more carbon monoxide and stresses the exchanger. We inspect with visual, combustion, and where indicated, camera inspection. Replacement requires full furnace removal in many cases, and we won’t patch or ignore a crack — the risk isn’t worth it. If your furnace is over 15 years old with exchanger damage, we’ll give honest repair-versus-replace guidance based on your specific system and home.

Trusted Brands We Service in Crestline
We service and stock parts for Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard — so Crestline homeowners are never told “we don’t work on that.” For common mountain installations like Goodman propane furnaces and Rheem mid-efficiency units, we carry local inventory to avoid waiting on valley supply houses. Your system, our specialty. Factory-trained compatibility across all nine brands means faster turnaround and fewer return trips on snow-complicated roads.
Common Heating & Furnace Problems We See in Crestline Homes
- Propane furnaces running rich and sooting up. Valley technicians often skip altitude de-rating during install or service. The furnace burns incompletely, coats the heat exchanger and flue in soot, and eventually short-cycles on high-limit. The fix isn’t new equipment — it’s proper orifice and manifold pressure adjustment for 4,500 feet.
- Undersized ductwork in converted cabins. Original A-frames and vacation builds had minimal or no ducting. Retrofitted systems often can’t move enough air for the heat load during severe cold, causing the furnace to trip limits and rooms to heat unevenly. We evaluate airflow per room and recommend duct modifications or ductless alternatives.
- Snowed-in propane tanks and frozen regulators. Mid-winter cold snaps in Crestline can bury tank domes in drifted snow and freeze first-stage regulators. Intermittent supply causes flame loss, lockouts, and no-heat calls that look like furnace failure but trace back to fuel delivery infrastructure.
- Failed ignitors and flame sensors in harsh conditions. Cold starts, moisture from snowmelt in crawl spaces, and temperature swings stress ignition components. These are straightforward repairs if diagnosed correctly, but altitude combustion issues can mimic or compound them.

FAQs — Heating & Furnace in Crestline
It’s almost certainly burning too rich because the manifold pressure wasn’t de-rated for altitude. At 4,500 feet, propane furnaces need smaller orifices and reduced manifold pressure to maintain proper air-fuel ratio. Valley-based technicians often skip this step, causing incomplete combustion, soot buildup, and eventual high-limit short-cycling. We clean the system and set combustion to manufacturer specs for your elevation. Call (844) 560-6978 to schedule — estimates are free.
Modern cold-climate mini-splits rated to -13°F or lower can handle most Crestline winter conditions, especially as supplemental or zoned heat in A-frames without ductwork. Extreme cold snaps may require propane backup or hyper-heat models. We size for your home’s insulation level and worst-case temperature, not average weather. Call (844) 560-6978 for a load calculation and honest assessment of whether mini-splits fit your specific property.
Three Crestline-specific causes dominate: a furnace burning rich from improper altitude setup trips the high-limit safety; undersized ductwork can’t move enough air and the same limit switch opens; or snow and ice restrict propane flow to the point of flame loss and lockout. Each requires different fixes, and misdiagnosis wastes money. Our techs test combustion, airflow, and fuel supply before recommending parts. Call (844) 560-6978 for same-day diagnostic service.
Standard thermostats work, but propane furnaces benefit from proper anticipator or cycle-rate settings to avoid short-cycling. Smart thermostats must be configured for forced-air propane, not natural gas defaults. In Crestline’s poorly insulated cabins, we also recommend location away from exterior walls and consideration of remote temperature sensors for multi-level A-frames. We set this correctly during tune-up or install. Call (844) 560-6978 for configuration help.
Once yearly, ideally in early fall before first snow. Crestline’s hard winters, propane combustion demands, and altitude-specific adjustments make preseason tune-ups more critical than in milder climates. Annual service catches flame sensor degradation, heat exchanger stress, and regulator issues before they become mid-winter emergencies. At $80–$200, it’s the cheapest insurance against a no-heat call at 4,500 feet in January. Call (844) 560-6978 to schedule.
