Fast, Reliable Heating & Furnace Across Ukiah
Heating and furnace repair in Ukiah typically costs $150–$700, with most service calls completed same-day when you call (844) 560-6978. Furnace replacement runs $3,500–$7,500 depending on whether your home needs propane-compatible equipment, ductwork modifications, or electrical upgrades. Our Heating & Furnace team makes the drive up Highway 101 from San Jose to Ukiah regularly, and we’ve built our schedule around Mendocino County’s reality: when your furnace quits during a January freeze or your heat exchanger cracks after decades of Ukiah’s hard freeze-thaw cycles, you can’t wait for a technician who doesn’t understand propane systems or Victorian-era floor plans.
We’ve been serving Northern California for nearly two decades, and Ukiah’s older housing stock keeps us busy year-round. The Craftsman bungalows near School Street, the ranch homes spread across the valley floor, and the rural properties on propane tanks out toward Talmage Road all present heating challenges that suburban Santa Rosa techs rarely face. Owner Marcus Feldman still manages jobs in the field, which means when you call Crestview, you’re getting ownership-level accountability built into the dispatch, not a call-center script.
Why Crestview Heating & Air California Is Ukiah’s Preferred Heating & Furnace Company
Our 4.8-star average across 250+ customer reviews reflects real-world performance on jobs exactly like yours: retrofitting modern furnaces into tight Ukiah attics, troubleshooting propane regulator issues after Mendocino County storms, and replacing heat exchangers before they become carbon monoxide hazards. Ukiah customers specifically mention our willingness to explain the “why” behind a repair versus replacement recommendation. That’s Marcus’s influence as both Owner and Service Manager. He still reviews complex jobs personally.
Response time to Ukiah depends on season and routing, but we schedule Mendocino County runs to cluster appointments and minimize wait times. We’ve learned the local patterns: PG&E’s PSPS shutoffs spike emergency calls, freeze events in late December through February overwhelm slower shops, and the pre-winter tune-up rush starts in October when Ukiah’s overnight lows first dip into the 30s. We plan around these rhythms so you’re not left waiting with a cold house.
Our familiarity with Ukiah’s housing matters. We’ve worked on gravity furnaces in downtown Victorians, mid-century ranch systems with original ductwork, and modern propane installations on rural acreage. That range means we don’t guess when we walk into your home. We know the common failure modes, the parts availability constraints, and when a creative retrofit beats a full replacement.
Our Heating & Furnace Services in Ukiah
Furnace Repair
Furnace repair in Ukiah demands more than swapping ignitors. The valley’s 40-degree overnight temperature swings stress heat exchangers through repeated expansion and contraction. We’ve replaced cracked exchangers in homes near Low Gap Park where the furnace ran hard all night, then sat cold by morning. Propane systems add another layer: regulator failures from tank moisture, sediment-clogged gas valves, and pilot outages in drafty old homes. Our diagnostic process starts with combustion analysis and carbon monoxide testing, not guesswork. Typical Ukiah furnace repair runs $150–$700 depending on parts and accessibility.
Furnace Replacement
Replacing a furnace in Ukiah often means more than a simple swap. Homes built without central air frequently lack adequate electrical service or ductwork sizing for modern high-efficiency units. We’ve pulled original gravity furnaces from 1920s bungalows where the basement clearance was barely 5 feet, and we’ve upgraded ranch homes with new propane-fired systems when the old oil tank finally failed. A standard replacement starts around $3,500, but complex retrofits with ductwork modifications or electrical panel upgrades can reach $7,500. We recently retrofitted a forced-air propane furnace in a Craftsman bungalow near Low Gap Park, where the old gravity furnace was swapped for a Carrier propane unit with a battery-backup thermostat—essential during PG&E shutoffs.
Furnace Tune-Up
Ukiah’s dual-extreme climate punishes neglected furnaces. Our tune-up runs $80–$200 and includes combustion analysis, heat exchanger inspection, gas pressure verification, and filter sizing for your specific system. For propane customers, we check regulator function and tank connection integrity, since Mendocino County’s wet winters accelerate corrosion at fittings. We schedule these aggressively in October before the first freeze, because a tune-up that catches a cracked exchanger or failing ignitor in fall beats an emergency call at midnight in January.
Heat Exchanger Inspection & Replacement
Heat exchanger cracks are the most dangerous failure we find in Ukiah homes. The valley’s hard freeze-thaw cycles, combined with decades of heating-season runtime in older homes, create metal fatigue that leads to carbon monoxide leakage into living spaces. We inspect with visual borescope and combustion analysis, not just a flashlight glance. Replacement costs vary with furnace age and brand availability, but we stock compatible heat exchangers for Carrier, Trane, Lennox, and Rheem to minimize wait times for Ukiah customers. If your furnace is over 15 years old with a cracked exchanger, we’ll walk you through honest repair-versus-replace numbers.

Trusted Brands We Service in Ukiah
Your system, our specialty. We maintain factory-trained compatibility across nine major brands, and for Ukiah’s market we stock parts and complete systems from Trane, Lennox, Goodman, and Rheem. Trane’s XV series handles Ukiah’s temperature extremes well, while Lennox’s propane-compatible SL280V is a frequent recommendation for rural Mendocino County homes off the gas main. Goodman offers solid value for rental properties and budget-conscious replacements in older neighborhoods. Rheem’s Classic Plus line pairs reliability with parts availability that’s critical when you’re two hours from a major distribution center. We don’t tell you “we don’t work on that.” If it’s heating your Ukiah home, we’ve likely repaired it, replaced it, or retrofitted around it.
Common Heating & Furnace Problems We See in Ukiah Homes
- Heat exchanger cracks from freeze-thaw cycling. Ukiah’s 40°F overnight swings, common from November through March, force metal heat exchangers through repeated expansion and contraction. After 15–20 years, hairline cracks develop that leak combustion gases into ductwork. We catch these with borescope inspection during tune-ups, because carbon monoxide detectors alone won’t always trigger before symptoms appear.
- Propane regulator failures on rural properties. Approximately 30% of Ukiah homes still heat with propane-fired furnaces, a legacy of rural gas-main gaps that HVAC techs in coastal NorCal almost never encounter. Tank moisture and sediment migrate into regulators during Mendocino County’s wet winters, causing pressure fluctuations that starve or overfire burners. Annual regulator inspection isn’t optional for propane customers.
- Pilot-light outages in drafty Victorian-era homes. The original homes near School Street and the downtown core often have unsealed crawl spaces, original windows, and chimney flues that create enough draft to extinguish standing-pilot furnaces. We’ve converted dozens of these to electronic ignition for reliability, but where owners want to preserve original equipment, we install pilot shielding and draft stabilization.
- Undersized electrical panels blocking modern upgrades. Ukiah’s older housing stock frequently has 100-amp service or original fuse boxes that can’t handle the blower draw of a modern variable-speed furnace, let alone add air conditioning. We coordinate with licensed electricians on panel upgrades when needed, and we spec propane systems for homes where electrical service expansion isn’t practical.

FAQs — Heating & Furnace in Ukiah
Propane furnaces in Ukiah need extra maintenance because tank moisture and sediment migrate into regulators and gas valves during Mendocino County’s wet season, causing pressure fluctuations that affect combustion efficiency and safety. The 30% of local homes on propane face a maintenance profile that natural-gas customers don’t: annual regulator inspection, tank connection integrity checks, and burner orifice cleaning to handle propane’s higher BTU content. We build these steps into every propane tune-up we perform in Ukiah. Call (844) 560-6978 to schedule before the first heavy rains.
Yes, with modifications. We’ve retrofitted dozens of Craftsman and Victorian-era homes in Ukiah’s older core. The constraints are usually electrical service (original 100-amp panels need upgrading), ductwork routing (no existing forced-air infrastructure), and physical access (tight basements or crawl spaces). A high-efficiency condensing furnace also needs proper drain routing for acidic condensate, which can be tricky in homes with perimeter foundations and no sump. We assess these factors during our free estimate and give you honest numbers on what’s feasible versus what requires creative problem-solving. Call (844) 560-6978 to walk through your specific home.
We most often spec Lennox and Rheem for propane installations in Mendocino County. Lennox’s SL280V variable-speed furnace offers excellent propane compatibility and pairs well with battery-backup thermostats for PG&E shutoff resilience. Rheem’s Classic Plus series provides reliable performance with strong parts availability, which matters when you’re hours from major distribution centers. Both brands have proven track records in our propane retrofit work across Ukiah’s rural fringe. We’ll match the specific model to your home’s size, ductwork, and electrical service during our in-home assessment. Call (844) 560-6978 for brand-specific recommendations.
Sometimes, but Ukiah’s climate creates genuine trade-offs. Heat pumps work well for shoulder-season heating and provide cooling during the valley’s 100°F summer peaks, but efficiency drops during hard freeze events below 30°F. For homes with adequate electrical service and solar offset, a cold-climate heat pump with propane backup can eliminate dual-fuel complexity. For rural propane customers, a propane furnace with a separate cooling retrofit may cost less upfront and perform more reliably during January cold snaps. We’ve installed both configurations in Ukiah, and we’ll run the numbers honestly for your situation. Call (844) 560-6978 to compare options.
Annually, without exception. Ukiah’s hard freeze-thaw cycles accelerate metal fatigue in heat exchangers more than mild coastal climates do. We inspect with borescope and combustion analysis during every tune-up, and we recommend scheduling before heating season starts in October. A cracked heat exchanger can leak carbon monoxide into your ductwork for weeks before a detector triggers, and the symptoms mimic common winter illness. The $80–$200 tune-up cost is negligible compared to the alternative. Call (844) 560-6978 to book your inspection.
