Fast, Reliable Heating & Furnace Across Temple City
Heating and furnace work in Temple City almost always means retrofitting 1950s–1970s ranch homes that were built with floor furnaces or wall heaters and no central ductwork. A typical furnace repair here runs $150–$700, while a full replacement with new ductwork can reach $3,500–$7,500 depending on attic access and home size. If your hallway closet still holds a 1960s floor furnace, we can assess whether it’s worth repairing or if a modern forced-air system makes more sense for your home. Call Stonegate Heating & Air California at (855) 467-1888 for a free estimate, and we’ll send our Heating & Furnace team to your Temple City home.
We’ve worked throughout the San Gabriel Valley for 16 years, and Temple City’s housing stock presents challenges you won’t find in newer suburbs. The shallow attics, low-pitch roofs, and original floor furnaces on streets like Kauffman Avenue and Las Tunas Drive require a contractor who’s done this exact work before, not a technician reading specs for the first time. Owner Jason Trent supervises every project as Field Supervisor, so the person quoting your job is the same person making sure it’s done right.
Why Stonegate Heating & Air California Is Temple City’s Preferred Heating & Furnace Company
Temple City homeowners research before they call, and they should. We’ve earned 499 verified reviews averaging 4.7 stars across platforms because we show up, explain the actual problem, and fix it without upselling what you don’t need. That review volume matters, it means hundreds of real customers, not a handful of cherry-picked testimonials.
Our response time to Temple City is typically same-day or next-day for non-emergency calls, and we keep common parts in stock for Carrier, Trane, Lennox, and Goodman systems so we’re not ordering components while your house sits cold. We know the 91780 zip code well, from the post-war ranches near Temple City Park to the renovated homes off Rosemead Boulevard, and we understand how the San Gabriel Valley’s inland heat affects both heating and cooling loads.
Jason Trent doesn’t delegate supervision to a project manager. He’s on job sites, checking duct runs, verifying clearances in those tight Temple City attics, and making sure load calculations account for the room additions and garage conversions that are common here. That’s accountability you don’t get from franchise chains sending whichever tech is available.
Our Heating & Furnace Services in Temple City
Furnace Repair
Most furnace repair calls we get in Temple City aren’t for modern forced-air units, they’re for original floor furnaces still running in hallway closets. A typical repair runs $150–$700. We see cracked heat exchangers, seized gas valves, and failed thermocouples on equipment that’s 50–60 years old. The question we always ask: is this repair buying you two years or ten? Sometimes a new thermocouple keeps a floor furnace running through another winter. Sometimes the heat exchanger crack means replacement parts don’t exist anymore, and we need to talk about retrofitting ductwork. We’ll give you an honest assessment.
Furnace Replacement
Furnace replacement in Temple City is rarely a simple swap. Because most homes were built without central ductwork, we’re typically installing a new gas furnace in a closet or garage and threading supply and return ducts through attics that hit 150°F in July and offer maybe 28 inches of clearance. A full replacement with ductwork runs $3,500–$7,500. We size equipment for Temple City’s actual conditions, not coastal LA specs. Summer highs here hit 100–108°F, 20–25 degrees hotter than the beach on the same afternoon, and that inland heat island effect means your system works harder than standard calculations suggest. We account for that.
Furnace Tune-Up
A furnace tune-up in Temple City costs $80–$200 and should happen before the heating season starts. For homes with original floor furnaces, we inspect the heat exchanger for cracks, test gas pressure and combustion, and check whether the unit still meets safety standards. For newer forced-air systems, we clean burners, check flame sensors, test limit switches, and verify airflow through those tight attic duct runs. Given Temple City’s renovation activity, room additions and garage conversions often change the original load calculation, so we recheck whether your furnace is still properly sized.
Heat Exchanger Repair & Replacement
Heat exchanger work is where Temple City’s housing age becomes critical. Original 1960s floor furnaces have cast-iron heat exchangers that develop hairline cracks over decades of thermal cycling. A cracked heat exchanger leaks carbon monoxide into your living space. Replacement heat exchangers for these units are often discontinued, and even when available, the labor to extract one from a floor furnace cabinet frequently exceeds the value of the unit. We charge $400–$1,500 for heat exchanger work when it’s feasible, but we’ll tell you straight if a full system retrofit makes more financial sense.

Trusted Brands We Service in Temple City
We work on nine major HVAC brands, Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard, which means we don’t turn you away with “we don’t service that brand.” For Temple City customers, this matters because replacement parts for 50-year-old Rheem or Coleman floor furnaces are increasingly unavailable, and when we retrofit your home with a modern system, we can recommend whichever brand fits your budget and efficiency goals. We stock common components locally to minimize wait times, and our technicians are factory-trained or field-experienced across the full range.
Common Heating & Furnace Problems We See in Temple City Homes
- Cracked heat exchangers in original floor furnaces. The cast-iron exchangers in 1960s units thermal-cycle themselves to failure over 60 years. We find hairline cracks leaking CO into hallway closets. This is a safety replacement, not a repair debate.
- Seized gas valves on discontinued equipment. Sediment buildup locks valves on ancient Rheem and Coleman units. When the manufacturer stopped making replacements, the only path is a full system retrofit with modern controls.
- Airflow restrictions from tight attic ductwork. New supply runs in Temple City’s low-slope attics often have too many bends or insufficient diameter. The furnace short-cycles, overheats, and fails prematurely. We redesign for actual static pressure, not theoretical.
- Undersized systems from coastal load calculations. Contractors using LA basin specs install equipment that can’t handle Temple City’s 108°F spikes. We size for San Gabriel Valley reality, not Santa Monica assumptions.
Pricing for Heating & Furnace in Temple City, CA
Here’s what heating and furnace work costs in Temple City’s market. These are real ranges based on 16 years of jobs across the San Gabriel Valley:
| Service | Price Range in Temple City |
|---|---|
| Furnace Repair | $150–$700 |
| Furnace Replacement (with ductwork retrofit) | $3,500–$7,500 |
| Heat Exchanger Repair/Replacement | $400–$1,500 |
| Furnace Tune-Up | $80–$200 |
What moves you within these ranges? Attic access is the big variable. A ranch home on Temple City’s north side with a slightly steeper pitch might take six hours for ductwork. A home with 24-inch clearance and a low roofline takes longer, requires more custom fittings, and costs more. Parts availability matters too, discontinued gas valves or obsolete heat exchangers can turn a $400 repair into a $5,000 retrofit decision. We explain this before we start, not after we’re halfway in. Estimates are free. Call (855) 467-1888 to schedule.

FAQs — Heating & Furnace in Temple City
No. Most Temple City ranch homes were built with floor furnaces or wall heaters and no central duct system. Adding a forced-air furnace requires threading new supply and return ducts through shallow attics, which is why retrofit work dominates our Temple City calls. Call (855) 467-1888 for a free assessment of your home’s ductwork options.
They don’t fail from summer heat directly, but the thermal stress of decades of cycling, combined with corrosion from San Gabriel Valley humidity swings, weakens cast-iron heat exchangers and gas valve components. Many homeowners only discover the damage when they fire up the heat in November. We inspect these units year-round, summer is actually ideal for replacement planning. Call (855) 467-1888 to schedule a pre-season check.
Sometimes, but rarely economically. Replacement heat exchangers for 1960s floor furnaces are often discontinued, and even when available, the labor to extract and install one in a compact cabinet approaches the cost of a new system. We charge $400–$1,500 for heat exchanger work when it’s viable, but we’ll recommend a full retrofit if parts are unavailable or the unit has additional wear. Call (855) 467-1888 and we’ll inspect before quoting.
A full furnace replacement with new ductwork in Temple City typically runs $3,500–$7,500. The variable is attic access. Low-pitch roofs with 24–30 inches of clearance require more custom fittings and longer labor hours than homes with slightly steeper pitches. Room additions and garage conversions, common in Temple City’s investment-heavy market, can also extend duct runs and add cost. Call (855) 467-1888 for an exact quote based on your home’s layout.
Yes, especially if you’re retrofitting from a 1960s floor furnace that was maybe 60–70% efficient. Modern 96% efficient units cut gas bills significantly, and the sealed combustion design is safer than an open flame in a hallway closet. The payback period depends on your heating load and gas rates, but the safety and comfort improvement is immediate. We installed a 96% Carrier in a Kauffman Avenue home with a cracked 1962 floor furnace, threading ducts through a 28-inch attic in July, and the homeowner gained both efficiency and peace of mind. Call (855) 467-1888 to compare options.
