Lennox HVAC in Strawberry, CA | Redwood Heating & Air San Diego
Redwood Heating & Air provides independent Lennox service throughout Strawberry’s 95375 ZIP code, specializing in propane furnace conversions and freeze-protection systems for mountain cabins at 5,000 feet elevation. We’re not a Lennox dealer — we’re a Master Technician-led shop that happens to know these machines cold, including the specific orifice changes and pressure adjustments that valley-trained crews routinely miss up here. If your cabin’s Lennox won’t fire after sitting empty through a hard freeze, call us at (844) 875-9451 — we stock the ignitors, pressure switches, and vent hardware to fix it same day.
Why Strawberry Residents Choose Us for Lennox Service
Gregory Hahn founded this company and still leads every technical decision. After 13 years and 428 reviews averaging 4.6 stars, we’ve learned that Strawberry isn’t like the towns 30 miles downhill. Every Lennox furnace up here burns propane, not natural gas. Every vent termination has to clear 10-plus feet of snowpack. And every cabin that sits dark for three weeks in January needs freeze-stat protection that actually works.
We service nine major HVAC brands — Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard — which means we diagnose what failed, not what brand the manual says to sell. Our Lennox sales & service covers everything from 1980s G60 units still clanking along in A-frames to newer Signature SLP98V installations. We carry OEM Lennox heat exchangers and circuit boards, plus premium aftermarket capacitors and contactors rated for high-altitude operation. Gregory trained in HVAC and refrigeration technology at Miramar College, and he’ll tell you straight whether your 15-year Merit system has another winter in it or if you’re throwing money at a rusted heat exchanger.
Our parts van stocks propane orifices, universal ignitors pre-tested for LP gas, raised vent caps, and heat tape kits. That matters in Strawberry, where driving to a valley supplier for one fitting can burn half a day.
Common Lennox HVAC Problems We Solve in Strawberry
- Propane ignitor failure on cold starts. The Lennox G60 and Merit ML180UH use hot-surface ignitors that thermal-shock when a cabin drops to 25°F for two weeks, then suddenly demands heat. We stock replacements pre-tested for propane combustion — not the natural-gas spec that valley suppliers push — and we’ll verify the gas pressure at the manifold while we’re there.
- Frozen condensate lines locking out Merit ML180UH units. Strawberry’s snowpack buries low vent terminations by January. When condensate backs up and freezes, the pressure switch opens and the furnace dies. We relocate terminations above drift lines and install self-regulating heat tape on the drain path. Last December, we got a call from a cabin on Leland Drive in Strawberry. The owner had driven up from Modesto to find the place at 38°F. Our tech arrived to find a Lennox G60 furnace locked out on a failed pressure switch — the condensate line had frozen solid because the vent termination was 6 inches too low relative to the snowpack. We replaced the switch, relocated the vent termination above the drift line, and installed heat tape. By noon the cabin was toasty, and we set the thermostat to 45°F to prevent a repeat freeze-up.
- High-pressure lockout on XC20 condensers from pine debris. Strawberry’s ponderosa pines and black oaks shed needles and catkins that pack tight into Lennox XC20 coil fins. Spring cleaning isn’t optional here — it’s what keeps your compressor from cutting out on a 85°F July afternoon when you finally want cooling.
- Signature SLP98V secondary heat exchanger rust. Intermittent use in unheated cabins lets condensation sit in the secondary cell between visits. We inspect annually with a borescope, and if we find flaking or pinholes, we quote OEM replacement or discuss whether a new unit makes sense for a seasonal structure.
- Pressure switch failure from improper propane conversion. The orifice swap from natural gas to propane changes combustion dynamics. If the manifold pressure isn’t dialed to 10.0 inches water column on a Lennox furnace, the pressure switch sees abnormal vacuum and trips intermittently. We gauge it every time.
Lennox Service in Strawberry: What Local Conditions Mean for Your Equipment
Strawberry’s lack of natural gas means every Lennox furnace we install or service runs on propane, requiring a specific orifice change and gas pressure adjustment that valley-based techs often miss. Additionally, many cabins sit dark for weeks in winter, so freeze-stat protection and remote shut-off are as critical as the furnace itself.
Highway 108 closes during heavy storms. When it does, you’re either prepared or you’re frozen. We design Lennox service in Cameron Park and Strawberry with that isolation in mind — WiFi thermostats with low-temperature alerts, redundant freeze-stats hardwired to keep circulation pumps running, and propane systems we verify will light on the first try after a three-week shutdown. The wood-frame cabins built here in the 1960s and 70s weren’t engineered for modern HVAC loads, so we size carefully. An oversized Lennox Signature SLP98V will short-cycle itself to death in a leaky 800-square-foot A-frame. We measure heat loss, account for wind exposure, and spec the smallest unit that’ll hold 45°F when you’re not there and 68°F when you are.
Lennox Models & Products We Service in Strawberry
We work on the full Lennox residential and light-commercial lineup, with particular depth on the units we see most in mountain cabins:
- Signature Collection: SLP98V modulating gas furnace — we handle propane conversions, secondary heat exchanger inspections, and the complex control diagnostics these units require.
- Merit Series: ML180UH and ML193UH single-stage furnaces — the workhorses in Strawberry’s older cabins, often still running after 20 years with proper maintenance.
- Elite Series: XC20 variable-capacity AC and XP20 heat pump — we clean coils, check charge for 5,000-foot elevation, and verify defrost logic for mountain humidity patterns.
- Legacy / Discontinued: G60 and G50 series — still common in 1970s cabins, and we stock cross-reference parts to keep them running when OEM supply dries up.
For critical components — heat exchangers, control boards, pressure switches — we use OEM Lennox parts. For consumables like capacitors and contactors, we source premium aftermarket equivalents rated for high-altitude and wider temperature swings. Our van carries the propane orifices, vent caps, and heat tape that Strawberry jobs demand, so we’re not making two trips.

What drives cost? Propane conversion complexity, vent relocation for snow clearance, and whether your cabin’s electrical panel can handle a modern variable-speed blower. A simple ignitor swap on a Merit ML180UH runs toward the low end. A Signature SLP98V replacement with new venting, gas line work, and WiFi thermostat integration lands higher. Our estimates are free and itemized — no mystery charges, no pressure to replace what still has life. Call (844) 875-9451 and we’ll walk through what you’re seeing.

FAQs — Lennox HVAC in Strawberry
Probably, but not certainly. Hot-surface ignitors on Lennox G60 and ML180UH units crack from thermal shock when cabins drop below freezing between visits. We test resistance across the ignitor first — open circuit means replacement. We also verify propane pressure at the manifold, since weak gas delivery mimics ignitor failure. Call (844) 875-9451 for same-day diagnosis; estimates are free.
Minimum 12 inches above the historical maximum snow depth for your specific exposure, and higher if you’re on the windward side of a drift-prone slope. We’ve seen 18-foot drifts on Leland Drive cabins. We install vent terminations at 24 inches minimum with snow shields, and we verify condensate drain pitch so nothing pools and freezes. If your current vent is less than a foot above roofline, it’s a freeze-out waiting to happen.
If the heat exchanger is sound and you’re not there full-time, probably not. A Signature SLP98V’s 98% efficiency is wasted on intermittent occupancy — the payback math doesn’t work. We typically recommend keeping the Merit running with annual borescope inspections and saving replacement for when the secondary cell fails or propane costs spike. Gregory Hahn will tell you straight: if I wouldn’t put it in my own house, I’m not recommending it for yours.
Yes — Tuolumne County requires permits for furnace replacements, including propane conversions and vent modifications. We pull permits on every job, coordinate inspections, and ensure your installation meets California Title 24 energy code. Skipping this risks insurance denial if there’s ever a fire or CO incident.
Absolutely. We install Lennox mini-split systems in ductless cabins regularly — and we offer Rancho Murieta Lennox service too — single-zone for small A-frames, multi-zone for larger mountain homes with additions. The outdoor unit mounts on a stand above snow line, and we spec cold-climate compressors rated to 5°F for Strawberry’s hard freezes. No ductwork needed, and you’ll get heating and cooling from one system. Call (844) 875-9451 to size one for your cabin.
