Call (855) 467-1888 for a free estimate.
We’re the Heating & Furnace crew that shows up with parts for Carrier, Trane, Lennox, and the other major brands already on the truck. Tujunga’s elevation, wind exposure, and postwar housing stock create furnace problems you won’t find in Burbank or Glendale. Jason Trent, our owner and Field Supervisor, has supervised jobs from Foothill Boulevard up to the Angeles National Forest boundary. We don’t send rookies to figure out your canyon home on your dime.
Why Stonegate Heating & Air California Is Tujunga’s Preferred Heating & Furnace Company
Our 499 verified reviews at 4.7 stars include plenty from Tujunga homeowners who found us after franchise chains couldn’t diagnose their canyon-specific issues. They mention the same things: Jason Trent was on-site, the crew understood older homes, and the fix held through winter.
We’re based in Sacramento with California-wide coverage, and Tujunga is squarely in our service radius. When a furnace fails on a cold January night at 1,600 feet elevation, “tomorrow morning” isn’t good enough. We prioritize heating emergencies, especially where hard-freeze conditions threaten pipes and safety.
Our 16 years in business means we’ve seen how Tujunga’s 1940s–1960s ranch homes and hillside bungalows challenge modern HVAC installation. Low attics, cramped crawl spaces, and framing never designed for air-handler clearances — we navigate these constraints without damaging original structure. Owner supervision on every project means no shortcuts through your roofline or joists.
We carry factory training for nine brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. Whatever furnace is in your Tujunga home, we’ve likely serviced its exact model before.
Our Heating & Furnace Services in Tujunga
Furnace Replacement
Tujunga’s postwar housing stock was built for wall furnaces and floor heaters, not central forced-air systems. We replace those original units with properly sized, high-efficiency gas furnaces that handle the canyon’s hard-freeze winters without cycling on and off constantly. A typical furnace replacement in Tujunga runs $3,500–$7,500 depending on whether we’re retrofitting ductwork into a 1948 ranch with no existing central system or swapping like-for-like in a home already converted.
We swapped out a seized 1960s wall furnace for a 96% AFUE Carrier gas furnace in a 1948 ranch-style home on Summitrose Street. The original was undersized for the 1,800-square-foot layout, and the homeowner wanted a heavy-duty unit to handle the canyon’s cold snaps without needing a second trip. Our crew fit the new furnace and ductwork in one long day, with a MERV-13 filter cabinet to tackle Bobcat Fire ash.

Heat Exchanger Repair & Replacement
This is where Tujunga’s canyon geography gets dangerous. The Santa Ana winds channeled down Big Tujunga Canyon pound exposed heat exchanger vents with sustained gusts that single-wall furnaces weren’t designed to withstand. Cracked heat exchangers leak carbon monoxide. We inspect with combustion analyzers and video borescopes, and we don’t mince words if a unit is unsafe.
Heat exchanger replacement in Tujunga typically falls within our $150–$700 repair range for accessible units, though some sealed-combustion models require full furnace replacement. We flag the danger clearly and document everything for your records.

Furnace Tune-Up
At $80–$200, a tune-up is cheap insurance against a $700 repair or $7,500 replacement. In Tujunga, our tune-ups include specific checks that flatland techs might skip: wind baffle integrity on vent terminations, condensate line freeze protection, and filter loading assessment calibrated for fire-season ash exposure. We also verify gas pressure settings for altitude, since Tujunga’s 1,400–1,800 foot elevation affects combustion efficiency.
Homes on south-facing slopes get extra attention for summer heat exposure on exterior components; canyon-facing homes get checked for debris accumulation from wind events. It’s not a checklist copied from a manual.

Furnace Repair
Ignitor failures, gas valve malfunctions, limit switch lockouts from clogged filters — we see the same failures as anywhere, but in Tujunga the root cause is often local. That limit switch tripped because a MERV-8 filter choked on Bobcat Fire ash in three days. That gas valve is struggling because low winter temperatures thickened the supply. Our repairs fix the symptom and address the cause.
Most Tujunga furnace repairs fall between $150–$700. We stock common ignitors, gas valves, control boards, and blower motors for Carrier, Trane, Lennox, and other major brands to complete the job in one visit.

Trusted Brands We Service in Tujunga
We’re factory-trained or field-experienced on Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Tujunga customers, this means we don’t order parts from a warehouse two counties away and make you wait. We carry the most common ignitors, gas valves, blower motors, and control boards for these brands on our trucks, and our supplier relationships get us next-day delivery on less common components. Whether your home has a 1990s Lennox pulse furnace in a La Tuna Canyon hillside bungalow or a newer Carrier infinity system in a Foothill Boulevard ranch, we’ve worked on that equipment before.
Common Heating & Furnace Problems We See in Tujunga Homes
- Hard-freeze cycling on undersized wall furnaces. Original 1940s–1960s wall furnaces in Tujunga’s postwar stock were sized for milder winters. When January temperatures drop into the 20s at 1,600 feet, these units run continuously and still can’t maintain setpoint, burning out fan motors and cracking heat exchangers from thermal stress.
- Santa Ana wind damage to venting and heat exchangers. The canyon’s orientation amplifies wind gusts that flex and eventually crack single-wall vent pipes and heat exchanger cells. We find CO leaks during fall tune-ups that homeowners never suspected, because the damage happens gradually over multiple wind events.
- Fire-season filter clogging and limit switch lockout. When Angeles National Forest fires run, ash and fine particulate flood Tujunga before evacuation orders. Standard MERV-8 filters load completely within days, choking airflow and causing the furnace to trip on high-limit. We’ve responded to dozens of these “no heat” calls that were purely filter-related but required system reset and safety verification.
- Altitude-related combustion inefficiency. Tujunga’s 1,400–1,800 foot elevation is enough to affect gas furnace combustion. Improperly derated systems run rich, sooting up heat exchangers and wasting fuel. We check and adjust gas pressure and air mixture as part of every tune-up and replacement.
Pricing for Heating & Furnace in Tujunga, CA
| Service | Typical Range in Tujunga |
|---|---|
| Furnace Repair | $150–$700 |
| Furnace Replacement | $3,500–$7,500 |
| Furnace Tune-Up | $80–$200 |
What moves you within these ranges? For repairs, it’s parts accessibility and whether the failure is accessible or buried in a tight attic crawl space common to Tujunga’s older homes. For replacement, ductwork retrofitting versus existing infrastructure is the biggest variable. A 1948 ranch with no central ducts needs more labor than a 1980s home already converted. We provide exact quotes after on-site assessment, and estimates are free. Call (855) 467-1888 to schedule.
We don’t offer financing terms we haven’t confirmed, and we don’t promise response times we can’t guarantee. What we do promise: owner-supervised work, upfront pricing before any work begins, and the 16 years and nearly 500 reviews to back it up.

FAQs — Heating & Furnace in Tujunga
Tujunga’s 1,600-foot elevation and canyon position produce genuine hard-freeze winters with multiple freeze events per year that Burbank’s flatland location rarely sees. A furnace sized for Burbank’s milder winter design temperature will run constantly and fail to maintain comfort on Tujunga’s coldest nights. We size for Tujunga’s actual heating load, not San Fernando Valley assumptions. Call (855) 467-1888 for a load calculation and exact quote.
Maybe, but it needs honest evaluation first. Tujunga’s postwar ranches have low, often unvented attics with 2×4 or 2×6 rafters never designed for the weight and clearance of a modern air handler. We’ve reinforced joists, framed equipment platforms, and routed ductwork through closets or soffits when attic installation wasn’t feasible. Jason Trent evaluates each home personally before we commit to a placement. Schedule a free assessment at (855) 467-1888.
During active fire events in the Angeles National Forest, check your filter weekly and replace it when visibly loaded — often every 7–14 days instead of the standard 90 days. Homeowners with MERV-13 or better filtration call us far less frequently for emergency service during fire season than those on standard MERV-8 stock. If you’re on basic filters, upgrade before the next fire season. We stock filter cabinets and can recommend sizing during any service call.
Gas furnaces remain the practical choice for most Tujunga homes due to the canyon’s hard-freeze winters and existing gas infrastructure. Heat pumps lose efficiency at low temperatures, and Tujunga’s winter lows regularly drop below the point where backup electric resistance becomes necessary. For homes without gas service or for specific zoned applications, modern cold-climate heat pumps can work, but we evaluate each property individually. Call (855) 467-1888 to discuss your specific situation.
Detached workshops in Tujunga’s acreage properties need dedicated heating calculated for uninsulated or partially insulated construction, not a extension of the home’s system. We size these separately, often recommending unit heaters or ductless mini-splits depending on use patterns and electrical service. The wide temperature swings at Tujunga’s elevation mean an undersized workshop heater will struggle on freeze nights and waste energy overshooting on mild days. We measure, calculate, and install for the actual building. Free estimates: (855) 467-1888.
