Fast, Reliable Heating & Furnace Across Alpine
Most furnace contractors in San Diego County never touch a propane system. Alpine’s different. We run into propane-fired furnaces on almost every call here, and we’ve spent 13 years learning what breaks when you’re heating at 2,000 feet with a tank in the yard instead of a gas meter at the curb. A typical furnace repair in Alpine runs $150–$700 and we’re usually there same day. Call (844) 875-9451 for a free estimate.
We’re based in San Diego but make the run east on I-8 regularly. Alpine’s 91901 and 91903 ZIP codes sit far enough from the coast that we see real winter, real summer, and real problems that coastal HVAC techs barely encounter. Gregory Hahn founded this company and still leads every technical decision, so when our truck pulls up to your place off Tavern Road or near the Viejas Casino corridor, you’re getting owner-level accountability, not a franchise dispatcher.
Why Redwood Heating & Air San Diego Is Alpine’s Preferred Heating & Furnace Company
Our reputation here was built one propane system at a time. We’ve got 428 verified customer reviews averaging 4.6 stars across 13 years of operation, and a meaningful chunk of those come from Alpine homeowners who were tired of coastal contractors fumbling with regulator adjustments and vent terminations they didn’t understand.
Response time to Alpine is typically same-day for furnace repairs and next-day for non-urgent replacements. We know the area: the post-Cedar Fire rebuilds with their modern air-handler closets but propane infrastructure, the surviving 1960s ranches on large lots with original ductwork, the newer construction near Alpine Boulevard. That local fluency means we diagnose faster and carry the right parts.
Gregory Hahn holds a Master Technician designation. The credential’s on the truck, not in a corporate office. For Alpine, that matters because propane furnace diagnostics require understanding both the appliance and the fuel delivery system — tank pressure, regulator performance, line sizing — skills that aren’t tested on standard natural-gas certification exams.
Our Heating & Furnace Services in Alpine
Furnace Repair
Propane furnaces in Alpine fail differently than natural gas units. We’ve tracked three distinct local patterns: regulator freeze-ups during rare snow events when tank pressure hasn’t been adjusted for 2,000 ft elevation; Santa Ana wind events blowing debris into gas valve intakes, causing flame rollout or ignition lockout; and short-cycling from oversized ductwork in older ranch homes that cracks heat exchangers over time. Our Heating & Furnace team carries regulators, gas valves, and ignitors for Carrier, Bryant, and American Standard propane units on every Alpine truck. Most repairs finish in two to four hours.
Furnace Replacement
When a propane furnace in Alpine reaches 15–20 years, replacement gets complicated. The new unit must be properly derated for elevation, paired with ductwork that won’t short-cycle it, and fitted with CAL FIRE-approved ember-resistant vent caps if the home sits in the Very High Fire Hazard Severity Zone. We’ve replaced systems in post-Cedar Fire rebuilds near Arnold Way and in original 1970s ranches off South Grade Road. Every installation includes combustion analysis to verify proper propane-air mixture at Alpine’s altitude. Typical replacement with a Bryant or American Standard propane furnace runs $3,800–$6,500 depending on duct remediation needs.
Furnace Tune-Up
Alpine’s dual-season load — 100°F summers, below-freezing winters — means your propane furnace works harder than coastal equivalents. We recommend annual tune-ups before the first cold snap, usually October. Our Alpine tune-up checklist includes propane pressure verification at the manifold, burner orifice inspection for elevation-specific sooting, heat exchanger examination for cracks from short-cycling, and vent cap mesh inspection for corrosion or damage. Santa Ana winds accelerate corrosion on everything exposed. A tune-up in Alpine runs $80–$200 and typically prevents the mid-winter emergency calls we see every January.
Heat Exchanger Inspection & Replacement
Cracked heat exchangers are the most dangerous failure we find in Alpine. The combination of oversized ductwork in 1960s–80s homes and modern high-efficiency propane furnaces forces rapid expansion and contraction that fatigues metal. We use combustion analyzers and borescope cameras to inspect without disassembly when possible. If replacement is needed, we factor in whether your existing duct system can handle a properly sized new furnace or needs modification. We’ve caught cracked exchangers in homes on Tavern Road and near the Alpine Community Center before they became carbon monoxide hazards.
Gas Valve Repair
Propane gas valves are not interchangeable with natural gas valves. The orifice sizes, spring pressures, and safety shutoff parameters differ. We’ve replaced valves on Daikin and Carrier propane furnaces where previous contractors installed natural-gas-spec components that created dangerous lean-burn conditions. Alpine’s Santa Ana wind events also drive fine dust into valve breathers, causing intermittent operation that mimics control board failure. Proper diagnosis saves you from replacing parts that aren’t actually broken.
Ignitor Replacement
Hot surface ignitors in propane furnaces operate at higher temperatures and fail faster than in natural gas units. We stock silicon nitride ignitors rated for propane service and carry OEM replacements for the brands we service most in Alpine: Carrier, Bryant, and American Standard.

Trusted Brands We Service in Alpine
We’re factory-trained or field-experienced across nine major HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Alpine specifically, we stock common propane conversion kits, gas valves, and ignitors for Carrier, Bryant, and American Standard because those brands dominate the post-Cedar Fire rebuild inventory. We also maintain relationships with San Diego County propane parts distributors for same-day or next-morning availability on less common Daikin and Rheem components. From a single mini-split to a full commercial system, we service your brand with parts that don’t require a two-week wait.
Common Heating & Furnace Problems We See in Alpine Homes
- Propane regulator freeze-ups during cold snaps. At 2,000 feet, Alpine sees temperatures coastal San Diego never does. If your propane tank pressure hasn’t been adjusted for elevation, the regulator can ice over and starve your furnace. We check tank pressure and regulator performance on every winter service call.
- Ember-damaged vent caps creating code violations. Post-Cedar Fire rebuilds required 1/8-inch corrosion-resistant mesh on all vent terminations. We’ve found caps corroded through or missing entirely, especially on homes near exposed ridgelines where Santa Ana winds hit hardest. Replacing these during furnace service prevents resale inspection failures.
- Short-cycling from mismatched ductwork. That 1970s ranch on a half-acre lot probably has ductwork sized for an 80% furnace running at higher airflow. Drop in a modern 95% propane unit and it overheats, cycles on and off every few minutes, and cracks the heat exchanger within seasons. We measure static pressure and calculate proper airflow before recommending any replacement.
- Condenser coil fouling from desert dust and ember debris. Alpine’s location in mountain passes means Santa Ana winds funnel dust, pollen, and burned material straight through outdoor units. For heat pump systems or dual-fuel setups, this kills efficiency and can trip high-pressure switches. We include coil cleaning in every tune-up.

We serviced a 2007 post-Cedar Fire rebuild on Tavern Road where the propane furnace’s vent cap was missing the required 1/8-inch corrosion-resistant mesh, a code violation that would have failed a resale inspection. We replaced the cap with a CAL FIRE-approved, ember-resistant unit and tuned the Carrier propane furnace for the high-elevation Santa Ana conditions. That’s the kind of Alpine-specific detail that separates a real technician from someone who just changed out a filter and left.

FAQs — Heating & Furnace in Alpine
Because Alpine sits in a CAL FIRE Very High Fire Hazard Severity Zone, post-2003 Cedar Fire rebuilds and many retrofits must use 1/8-inch corrosion-resistant mesh on all vent terminations to block ember intrusion. Standard galvanized caps corrode faster at 2,000 feet and don’t meet code. We inspect and replace damaged caps during every furnace service to keep your home compliant and insurable. Call (844) 875-9451 to schedule.
Once yearly, ideally in October before the first freeze. Alpine’s genuine four-season climate — summer highs over 100°F, winter lows below freezing — means your system works harder than coastal equivalents. Annual tune-ups catch regulator drift, burner sooting, and vent cap corrosion before they become mid-winter emergencies. Our Alpine tune-ups run $80–$200. Call (844) 875-9451 to book before the rush.
Yes, we verify and adjust tank regulator output pressure as part of furnace service and installation. Propane systems at 2,000 feet elevation require different pressure settings than sea-level installations, and improper adjustment causes regulator freeze-ups, poor combustion, and sooting. We don’t fill tanks — that’s your propane supplier — but we ensure the delivery pressure matches what your furnace was designed for. Call (844) 875-9451 for a pressure check.
Sometimes, but it’s rarely a simple swap. Alpine’s below-freezing winter nights and existing propane infrastructure mean you’ll likely need a cold-climate heat pump with auxiliary propane backup, plus ductwork modifications if your home has the oversized ducts common in 1960s–80s ranches. We evaluate heat loss, duct static pressure, and electrical panel capacity before recommending any conversion. Most Alpine homeowners find that a high-efficiency propane furnace replacement is more practical. Call (844) 875-9451 for an honest assessment.
We service, repair, and install all major brands, with particular depth in Carrier, Bryant, American Standard, and Daikin — the brands we see most in Alpine’s post-Cedar Fire rebuild housing stock. Gregory Hahn’s Master Technician credential covers nine major HVAC brands, so we diagnose based on engineering, not brand loyalty. If we don’t have your part in the truck, our San Diego County distributor relationships usually get it next day. Call (844) 875-9451 with your model number.
