We’ve been driving out to Old Fig Garden for 16 years. Jason Trent, our owner and active Field Supervisor, knows the neighborhood’s streets — Van Ness Boulevard, Palm Avenue, the winding lanes off Fig Lane — and more importantly, he knows what’s behind those walls. These aren’t tract homes with standardized ductwork. They’re architect-designed estates from the 1920s through 1950s with gravity furnaces, non-standard lateral sizes, and redwood millwork that can’t be replicated. That matters when you’re deciding whether to repair or replace.
Why Stonegate Heating & Air California Is Old Fig Garden’s Preferred Heating & Furnace Company
Our reputation in Old Fig Garden was built job by job, not through advertising. Nearly 500 verified customer reviews averaging 4.7 stars back up what we say — and several dozen of those reviews come from repeat customers right here in the 93704 ZIP code who’ve watched us hand-fabricate duct transitions, preserve original plaster, and size modern equipment for homes that were never designed for it.
Jason Trent doesn’t run this company from a back office. He’s the Field Supervisor on jobs, including the ones in Old Fig Garden’s historic district. When you call, you’re getting an owner-accountable crew, not a rotating subcontractor pool.
Response time to Old Fig Garden is typically same-day for heating emergencies during valley cold snaps, and next-day for non-urgent replacement consultations. We keep common parts for Carrier, Trane, Lennox, and other major brands stocked locally, which matters when your 60-year-old gas valve fails on a Friday evening and the house is dropping below 50°F.
We also understand the local failure patterns. Valley humidity rusts out original gravity furnace heat exchangers. Tall ceilings in these Spanish Colonial Revival and Craftsman homes create thermal stratification that old blowers can’t overcome. And the agricultural dust that drifts through Old Fig Garden during harvest season clogs filters faster than in most Fresno neighborhoods. That’s not textbook knowledge — that’s 16 years of California HVAC work showing up in your living room.
Our Heating & Furnace Services in Old Fig Garden
Furnace Repair
Furnace repair in Old Fig Garden starts at $150 for simple fixes like ignitor replacement or thermostat recalibration, and runs up to $700 for complex diagnostics on legacy systems with discontinued parts. We recently replaced a failing 1950s floor furnace in a Craftsman home on Van Ness Boulevard. The original ductwork used 4″x10″ laterals that don’t match any modern system, so our sheet metal shop hand-fabricated transition sections to adapt a new 96% AFUE Carrier gas furnace without disturbing the home’s original redwood millwork. That’s the difference between a tech who swaps parts and a team that solves problems.

Furnace Replacement
Full furnace replacement in Old Fig Garden homes ranges $3,500–$7,500, with the upper end reflecting the custom fabrication and Manual J load calculations these pre-war properties demand. Original gravity furnaces or early forced-air conversions with non-standard duct sizes make modern replacement a custom job rather than a simple swap-out. No drop-in replacement exists for most 1920s–1940s systems. We design from scratch, preserving what we can and upgrading what we must.

Furnace Tune-Up
Annual furnace tune-ups in Old Fig Garden run $80–$200 and pay for themselves in efficiency gains alone. These old systems run hard. Valley dust, legacy blower motors, and heat exchangers that have survived 60+ winters need more than a quick filter swap. Our tune-ups include combustion analysis, gas pressure verification, and inspection for the hairline cracks that develop in aging heat exchangers — a genuine carbon monoxide risk in homes with original millwork that’s too tight to ventilate passively.

Heat Exchanger Inspection & Replacement
Heat exchanger failure is the endgame for most Old Fig Garden gravity furnaces. Decades of valley humidity rust through steel that was never meant to last this long. When we find cracks or deterioration, we don’t patch — we replace, because CO leaks kill people. In some cases, the heat exchanger itself is discontinued and no replacement part exists, forcing a full system redesign. We’ll tell you straight which path you’re on and why.

We’re certified and experienced on nine leading manufacturers: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. We stock common parts for Carrier, Trane, and Lennox locally, which means faster turnaround when your system fails during a valley cold snap. No “we don’t service that brand” dead ends. No waiting two weeks for a special order on a part that should be on the truck.
Common Heating & Furnace Problems We See in Old Fig Garden Homes
- Original gravity furnaces rust out from valley humidity. The steel heat exchangers in these 1920s–1940s systems weren’t built to handle decades of San Joaquin Valley moisture. Parts have been discontinued for generations. When they fail, you’re looking at full system redesign, not a repair.
- Tall plaster-walled rooms create brutal stratification. Old furnaces lack the fan power to push heated air to 10-foot ceilings. Upstairs rooms stay cold even when the thermostat reads 72°F downstairs. Modern variable-speed blowers solve this, but only if the ductwork is designed for the house — not copied from a suburban tract plan.
- Legacy gas valves fail in ways modern controls can’t compensate for. Pre-1960 furnace gas valves weren’t built to today’s safety standards. When they start leaking or sticking, repair isn’t an option. Replacement requires adapting new safety controls to old burner configurations — something our Field Supervisor signs off on personally.
- Condenser units choke on fig and sycamore debris. The mature canopy that makes Old Fig Garden beautiful drops heavy leaf litter and seed pods directly into outdoor equipment. Local techs know to spec condenser covers and schedule fall cleanings around the neighborhood’s distinctive tree debris cycle. That’s rarely needed a mile east in post-war Fresno subdivisions.

FAQs — Heating & Furnace in Old Fig Garden
Yes, in most cases we can route new ductwork through existing chases, closets, or basement/crawl spaces without disturbing original plaster.
We’ve done this repeatedly on Van Ness Boulevard and throughout the 93704 ZIP code. The key is custom-fabricated transition pieces that adapt modern equipment to your home’s original duct configuration. Our sheet metal shop builds these in-house. Jason Trent reviews every routing plan personally before we cut anything. Some homes need one small access hole for a main trunk connection, but we patch and match — never a full wall demolition. Call (855) 467-1888 and we’ll walk your specific layout.
Replace the unit — heat exchangers this old have no available replacement parts, and cracked exchangers pose a lethal carbon monoxide risk.
We’ve never seen a 60+ year heat exchanger in Old Fig Garden that was repairable. The steel has fatigued, rust has thinned the walls, and the original manufacturer stopped supporting these models before most of us were born. A new high-efficiency furnace with a modern heat exchanger and sealed combustion is the only safe path. The $3,500–$7,500 replacement cost stings once. A CO poisoning incident stings forever. We don’t negotiate on this — if it’s cracked, it’s done. Call for a free replacement quote.
Short cycling in Old Fig Garden homes usually means your furnace is oversized for the ductwork, or the original ducts are too restrictive for modern airflow requirements.
We see this constantly in pre-war homes with early forced-air conversions. The 1940s installer sized a small blower for 4″x10″ laterals. A modern furnace moves more air, hits high limit, and shuts down — over and over. The fix isn’t another tune-up. It’s either duct modification, a properly sized two-stage furnace, or both. We measure static pressure and calculate actual airflow before recommending anything. Quick cycling wastes gas and destroys equipment. Call (855) 467-1888 for a proper diagnostic.
Sometimes, but it requires careful matching — modern high-efficiency furnaces need specific airflow rates that old, restrictive ductwork often can’t provide.
We’ve successfully paired 96% AFUE Carrier units with 1940s duct systems in Old Fig Garden, but only after pressure testing and often fabricating custom transitions. The danger is installing a modern furnace that can’t breathe through vintage ducts — it will short cycle, overheat, and fail early. We never drop in equipment without verifying compatibility. If your ducts won’t support it, we’ll tell you upfront and show you the numbers. Free estimates mean no surprises later.
They don’t directly affect furnace combustion air, but they heavily clog AC condensers and can block ventilation intakes if your system uses outdoor air for makeup or combustion.
The mature canopy in Old Fig Garden is beautiful and genuinely reduces cooling load through shading. But the leaf litter and seed pods are relentless. We recommend condenser covers during heavy drop periods and schedule fall cleanings specifically around the neighborhood’s tree debris cycle — something rarely needed in newer Fresno subdivisions. If your furnace pulls combustion air from outside, we’ll inspect those intakes during every tune-up. Blocked intakes cause incomplete combustion and CO risk. Call (855) 467-1888 to schedule a fall cleaning before the debris peaks.
Ready to get your Old Fig Garden home heating right? Whether it’s a rattling gravity furnace on Van Ness Boulevard, a cold upstairs in a Spanish Colonial Revival, or you’re done pouring money into a system that should have retired decades ago, we’ll give you a straight answer and a fair price. No upselling. No ghosting. Owner Jason Trent supervises every project personally. Call (855) 467-1888 for your free estimate today.
