Fast, Reliable Heating & Furnace Across Orinda
Heating and furnace repair in Orinda typically costs $150–$700, with most jobs completed same-day when you call (855) 467-1888. Furnace replacement runs higher, especially in Orinda’s mid-century homes where ductwork retrofits and electrical upgrades often join the scope. We’ve been driving to Orinda since 2009, and our Heating & Furnace team knows the terrain: hillside ranches on Sleepy Hollow Road, split-levels off El Toyonal, the tight crawl spaces beneath Glorietta’s 1960s builds. Jason Trent supervises every project personally. If your furnace is blowing cold, cycling too often, or you’re staring at a cracked heat exchanger, we’ll diagnose it honestly and give you a straight price before any work starts.
Why Stonegate Heating & Air California Is Orinda’s Preferred Heating & Furnace Company
Sixteen years in business and nearly 500 verified reviews at 4.7 stars — that volume matters because it means we’ve handled the exact problems Orinda homeowners face, repeatedly. Owner Jason Trent holds the title of Field Supervisor, not just Owner. He’s on job sites, not in a back office. When we get a call from Orinda, we’re pulling onto Highway 24 within the hour, crossing through the Caldecott Tunnel into that hotter inland valley where furnace and cooling demands differ sharply from what Berkeley or Oakland experience.
Our Orinda customers mention two things in reviews: we show up when we say we will, and we explain what we’re doing before we do it. That matters in a city where many homes have complex hillside foundations, original asbestos-wrapped ductwork, and electrical panels that haven’t been upgraded since the Ford administration. We’ve replaced heat exchangers in Orinda’s original Lennox furnaces, retrofitted Carrier split systems into hillside ranches with no existing cooling infrastructure, and walked homeowners through the real costs of repair versus replacement without pressure.
Whatever brand you have — Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, or American Standard — we service it. Nine brands, one team. No “we don’t work on that” dead ends.
Our Heating & Furnace Services in Orinda
Furnace Repair
A furnace that won’t ignite, blows cold air, or cycles every three minutes isn’t just uncomfortable in Orinda — it’s dangerous when winter nights drop into the 30s and your hillside home radiates cold from the foundation up. We repair ignitors, gas valves, blower motors, and control boards across all nine major brands. Most Orinda furnace repairs run $150–$700 depending on the part and accessibility. Many of the furnaces we service in Orinda are 20–30 years old, still functional but needing precise diagnosis to avoid unnecessary replacement. Jason Trent supervises every repair personally.
Furnace Replacement
This is where Orinda’s housing stock gets interesting. Many homes here have oversized gas furnaces from the 1970s or 1980s that heat adequately but eat fuel inefficiently and were never paired with any cooling system. When we quote furnace replacement in Orinda, we’re often quoting more than a box swap. We’re assessing whether your ductwork can handle a modern variable-speed furnace, whether your electrical panel can support the blower, and whether this is the moment to add cooling — because Orinda’s summers are genuinely hot, and a furnace-only home becomes unlivable during 100°F heat waves. Replacement costs vary with scope, but we’ll give you a written, itemized estimate before any work begins.
Furnace Tune-Up
An annual furnace tune-up in Orinda costs $80–$200 and typically catches the problems that become $400 emergency repairs by January. Our tune-up covers heat exchanger inspection, burner cleaning, gas pressure testing, and airflow measurement. In Orinda specifically, we pay extra attention to duct leakage in crawl spaces — those original asbestos-wrapped or uninsulated metal ducts lose 20–30% of heated air before it reaches your vents. A tune-up identifies this. We also check for proper venting on hillside homes where the furnace exhaust run may be longer than code minimums due to foundation height. Schedule before October; Orinda’s inland cold snaps hit earlier than the fog-locked cities west of the hills.
Heat Exchanger Inspection & Replacement
Cracked heat exchangers are the repair that stops conversations. In a 1970s Orinda furnace, the heat exchanger has endured 50 years of thermal expansion and contraction. If we find cracks during inspection, we red-tag the unit and shut it down — carbon monoxide risk is real, and we’re not negotiating on safety. Heat exchanger replacement in older furnaces often approaches the cost of full replacement, and we’ll tell you exactly where that line falls for your specific unit. We’ve made this call in Orinda’s Sleepy Hollow and Glorietta neighborhoods more times than we can count. The honest answer saves you money long-term.

Trusted Brands We Service in Orinda
We maintain active parts inventory and factory-trained experience on Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Orinda homeowners, this means faster turnaround — we’re not ordering a control board for your 1990s Rheem and waiting a week. On a recent call in the Glorietta neighborhood, we found a 1970s hillside ranch with a working Rheem furnace but no condenser pad or refrigerant lines — the original builder never planned for AC. We retrofitted a new Carrier split system, running linesets through a tight crawl space and replacing asbestos-wrapped ducts with modern insulated runs. That kind of job requires brand-specific knowledge and parts fluency we bring to every Orinda project.
Common Heating & Furnace Problems We See in Orinda Homes
- Oversized gas furnaces with no cooling infrastructure. The furnace works fine, but when Orinda hits 105°F in August, there’s zero relief. We regularly encounter homes where the original builder marketed the property as “Bay Area living” and skipped AC entirely. Retrofitting cooling without replacing the furnace is often possible — but requires honest assessment of your ductwork and electrical capacity.
- Aging asbestos-wrapped ducts in crawl spaces. Original 1960s–70s ductwork deteriorates, leaking heated air and creating efficiency losses of 25% or more. Replacement requires abatement-certified handling. We’ve managed this process for Orinda homeowners and can coordinate the abatement and re-ducting as part of a larger heating or cooling project.
- Undersized electrical panels. Many Orinda homes lack the dedicated 240V circuit a modern heat pump or AC requires. Adding cooling to a furnace-only home often means a panel upgrade — a real cost we disclose upfront, not after we’ve started.
- Original ignitors and gas valves reaching end of life. In Orinda’s mid-century furnaces, these components often fail simultaneously after 20+ years. We stock the common replacements for Rheem, Lennox, and Carrier units and can usually restore heat same-day.

FAQs — Heating & Furnace in Orinda
Yes, in many cases we can add a split-system air conditioner to your existing furnace and ductwork, provided the ducts are in reasonable condition and your electrical panel can handle the additional load. We evaluate duct capacity, static pressure, and whether your blower can support the increased airflow cooling requires. In Orinda specifically, we’ve completed this retrofit dozens of times in 1960s–70s homes where the original builder never installed cooling. Call (855) 467-1888 for a free assessment of your specific system.
We do not perform asbestos abatement ourselves, but we coordinate with certified abatement contractors and manage the entire project sequence for Orinda homeowners. The abatement happens first, then we install new insulated ductwork and complete your heating or cooling upgrade. This is a common scenario in Orinda’s mid-century homes, and we’ve guided many homeowners through the process. We’ll include abatement coordination in your written estimate if needed.
Heat exchanger replacement in a 1970s furnace typically runs $800–$1,500 for the part and labor, but we often recommend full furnace replacement instead. At 50 years old, the blower motor, gas valve, and control board are likely near failure too, and modern furnaces operate at 95% efficiency versus 60–70% for your original unit. We’ll inspect your specific furnace and give you both numbers — repair and replace — so you can decide. Estimates are free; call (855) 467-1888.
Yes, a tune-up typically restores 10–15% efficiency in an aging furnace by cleaning burners, adjusting gas pressure, and sealing minor duct leaks. For Orinda’s original 1970s furnaces, we also inspect the heat exchanger for cracks — a safety issue that produces no symptoms until it’s dangerous. A tune-up costs $80–$200 and often prevents the $400 emergency repair that happens the first cold night in November. Schedule before heating season.
Orinda sits east of the Caldecott Tunnel in a hot-summer microclimate that original mid-century builders didn’t plan for. They designed these homes as “Bay Area” properties, assuming marine layer cooling would reach them — it doesn’t. The Berkeley Hills block fog and trap inland heat, creating 40°F temperature differences between Orinda and Berkeley on the same August afternoon. Many homeowners only discover this reality during their first summer. We’ve retrofitted cooling into countless Orinda homes that never had it, and we can assess whether your furnace, ducts, and electrical can support the addition.
