Fast, Reliable Heating & Furnace Across Clearlake
Heating and furnace repair in Clearlake typically runs $150–$700, with most jobs completed same-day when you call (855) 467-1888. We’re the Heating & Furnace team at Stonegate Heating & Air California, and we’ve been driving out to Clearlake from our Sacramento base for 16 years. Owner Jason Trent supervises every project personally, so when we dispatch to your address off Olympic Drive or up into the hills above the lake basin, we’re coming with the right parts and the experience to fix it without a second trip. That’s the difference owner-accountable work makes in a rural market where a return visit costs you another day without heat.
Why Stonegate Heating & Air California Is Clearlake’s Preferred Heating & Furnace Company
We’ve earned 499 verified reviews at a 4.7-star average across platforms, and a growing share of those come from Clearlake homeowners who found us after frustrating experiences with contractors who didn’t understand manufactured home systems. Jason Trent doesn’t delegate from an office — he’s Field Supervisor on jobs, including the ones we run up Highway 20 into Lake County.
Our response time to Clearlake is typically same-day or next-morning for standard calls, with emergency HVAC available when your furnace fails during a January cold snap or your blower motor seizes mid-heat-wave. We carry parts for Carrier, Trane, Lennox, and Goodman on our trucks, which matters when you’re 30 minutes from the nearest supply house in Lakeport.
What separates us in Clearlake is housing-stock fluency. The concentration of manufactured and mobile homes here is among the highest in California, and those belly-pack duct systems fail in ways that standard suburban HVAC training doesn’t cover. We’ve replaced enough collapsed crossover ducts in Austin Park and along Lakeshore Drive to know the failure pattern before we park the truck.
Our Heating & Furnace Services in Clearlake
Furnace Repair in Clearlake
Most furnace repair calls we get in Clearlake trace back to three causes: original 1970s–1980s equipment finally failing, blower motors burned out from running recirculation mode during wildfire smoke events, or crossover duct collapses in manufactured homes that make the furnace work twice as hard for half the result. Our repair range is $150–$700 depending on component replacement — ignitor, gas valve, blower motor, or control board. We diagnose first, quote upfront, and stock the common failure parts for Carrier, Trane, Lennox, and Goodman systems.
Furnace Replacement in Clearlake
Replacement in Clearlake demands more than swapping boxes. Manufactured homes need belly-compatible air handlers with reinforced crossover ducts, not standard plenum connections. Stick-built ranches from the 1960s often need duct sealing and attic insulation upgrades before new equipment goes in, or you’ll oversize the furnace and short-cycle it to death. We size every replacement to the actual heat load, accounting for single-pane windows and deteriorated ductwork that are standard in Clearlake’s housing stock. Jason Trent signs off on every load calculation personally.
Furnace Tune-Up in Clearlake
A furnace tune-up in Clearlake runs $80–$200 and pays for itself in a market where deferred maintenance is the norm. We clean burners, test gas pressure, check heat exchanger integrity, and inspect blower amp draw — critical when your system’s been fighting wildfire smoke filters for weeks. For manufactured homes, we pull the belly panel and inspect crossover duct connections, something most tune-up checklists skip. We recommend annual service here, ahead of the heating season, because Clearlake’s summer heat stress on cooling systems often masks emerging furnace problems until the first cold night hits.
Heat Exchanger Inspection & Replacement
Cracked heat exchangers are a safety issue we take seriously, and they’re more common in Clearlake’s aging furnace population than most homeowners realize. The constant cycling caused by collapsed ducts or undersized returns creates thermal stress that fatigues metal. We inspect with visual and combustion analysis tools, and if replacement is needed, we coordinate the full job including permit coordination. No shortcuts on carbon monoxide risk.

Trusted Brands We Service in Clearlake
We’re certified and experienced on nine major HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Clearlake customers, this means no “we don’t service that brand” dead end. We stock common parts for Carrier, Trane, Lennox, and Goodman on our service trucks, and our supplier relationships get us same-day or next-day parts for the others. In a rural market where every day without heat matters, that parts access is the difference between a fixed furnace and a hotel bill.
Common Heating & Furnace Problems We See in Clearlake Homes
- Collapsed crossover ducts in manufactured homes. In a 1970s manufactured home in the Austin Park neighborhood, we found the crossover duct had collapsed under the belly due to ground moisture, causing a 15°F temperature split between rooms. We replaced the duct with a heavy-duty, reinforced crossover and upgraded the furnace to a Carrier unit with a MERV-13 filter to handle wildfire smoke. This failure mode is endemic to Clearlake’s manufactured housing stock and nearly invisible until the temperature imbalance becomes severe.
- Blower motor failure during wildfire smoke events. Clearlake’s position in the lake basin traps smoke from Lake County’s recurring fire seasons, forcing HVAC systems into recirculation mode for days. Original blower motors from the 1980s weren’t designed for that continuous load, and we replace burned-out motors every fire season.
- Undersized cooling systems failing during heat sieges. Summer temperatures on the Clearlake basin floor regularly spike past 105°F, and many installed systems were sized before climate extremes worsened. The same undersizing strains heating components during shoulder seasons when heat pumps switch modes.
- Deteriorated ductwork in stick-built ranch homes. The 1960s–1980s ranch stock around Clearlake commonly has original flex duct in attics that has degraded from rodent damage and temperature cycling. We find disconnected runs and major leakage that the furnace compensates for until it can’t.

FAQs — Heating & Furnace in Clearlake
It’s almost always a collapsed or disconnected crossover duct in the belly of the home. Ground moisture and foot traffic degrade these ducts over decades, and the conditioned air never reaches the far registers. We inspect the belly ductwork, replace with reinforced crossovers rated for manufactured home conditions, and rebalance airflow. Call (855) 467-1888 for a free inspection — estimates are free.
You need a system with a blower motor rated for continuous recirculation duty and cabinet space for at least MERV-13 filtration. Standard filters clog in hours during smoke events, choking airflow and burning out motors. We specify equipment with higher-static blower capacity and media filter cabinets for Clearlake’s conditions. Call (855) 467-1888 to discuss upgrade options.
Yes, and we do it regularly in Clearlake. The key is understanding belly-pack and crossover duct configurations that differ fundamentally from site-built homes. We carry the specialized duct connectors and reinforced crossovers these systems need, and Jason Trent personally reviews every manufactured home job before dispatch. Call (855) 467-1888 to schedule — we service the full age range of Clearlake’s housing stock.
For acreage properties in Clearlake, we typically recommend a central furnace sized for the main residence plus a separate mini-split or dedicated unit heater for the workshop, rather than trying to duct across distance. Gas line extension costs, workshop insulation levels, and how you use the space (occasional vs. daily) drive the specific recommendation. We assess each property individually. Call (855) 467-1888 for a site evaluation and free estimate.
Annually, before heating season starts. Clearlake’s summer heat stress and wildfire smoke put extra load on blower components and filters, and the age of most installed equipment means small problems become big failures fast. Our $80–$200 tune-up includes combustion analysis, heat exchanger inspection, and manufactured home duct connection checks that standard services skip. Call (855) 467-1888 to book your tune-up.
