Why Stonegate Heating & Air California Is Lomita’s Preferred Heating & Furnace Company
Lomita homeowners find us the same way most people find contractors now: they check reviews first. We’ve earned 499 verified reviews averaging 4.7 stars across platforms, and that volume matters more than any marketing claim. These aren’t a handful of cherry-picked testimonials from friends. They’re hundreds of real jobs, documented by real customers, many in South Bay cities like Lomita where we’ve replaced rusted floor furnaces and routed first-time ductwork through cramped attics.
Jason Trent doesn’t just own Stonegate; he holds the title of Field Supervisor and stays physically present on job sites. In Lomita, that means he’s the one measuring your attic clearance on Esplanade, checking gas line sizing near Lomita Park, or walking you through why your 1962 wall heater can’t be safely patched again. Franchise chains send whoever’s available. We send experienced, accountable hands.
Our familiarity with Lomita’s specific housing stock saves time and prevents callbacks. We know which blocks near the Palos Verdes border see faster corrosion from salt-laden air rolling off the Port of Los Angeles, roughly 3–4 miles away. We know which homes on Walnut Street still have original floor-furnace grates in living rooms. That local knowledge translates to accurate quotes and jobs done right without surprises.
Our Heating & Furnace Services in Lomita
Furnace Repair
Furnace repair in Lomita runs $150–$700 depending on the part and accessibility. Most calls we get here aren’t for standard forced-air units. They’re for original gas wall heaters in duplexes near Lomita Boulevard, or floor furnaces in 1,100-square-foot bungalows off Narbonne. The repair often involves tracking down discontinued ignitors or gas valves for Wedgewood and Empire models that haven’t been manufactured in decades. When parts exist, we fix it. When they don’t, we tell you honestly and pivot to replacement options.
Furnace Replacement
This is the defining job in Lomita. Full furnace replacement here typically costs $3,500–$7,500, but “replacement” is almost always a misnomer. Most Lomita homes were built with wall heaters or floor furnaces and no ductwork whatsoever. You’re not swapping a furnace. You’re installing a first-time forced-air system from scratch, or opting for a ductless mini-split heat pump that avoids tearing into walls.
On Osage Avenue, we replaced a crumbling 1958 Empire floor furnace that had a cracked heat exchanger, visible rust, and a pilot light that wouldn’t stay lit. The homeowner had never had central heat; we installed a new 95% AFUE gas furnace with ductwork routed through the attic, carefully threading between trusses to fit the compact 1,100 sq ft house. Jobs like this require creative routing through Lomita’s tight attics, many with low clearances and original knob-and-tube wiring still present. Jason Trent measures every joist space personally before we quote.
Furnace Tune-Up
A tune-up in Lomita costs $80–$200 and pays for itself in safety alone. We inspect heat exchangers for cracks that could leak carbon monoxide, test gas pressure and combustion, and check for rust or corrosion on cabinets exposed to marine-layer moisture. In Lomita’s 1950s–1960s housing stock, we often find wall heaters with soot buildup from incomplete combustion, or floor-furnace burners clogged with decades of dust and pet hair. Annual service catches these before they become emergencies.
Heat Exchanger Inspection & Replacement
Cracked heat exchangers are especially dangerous in Lomita’s older homes because many lack modern CO detection. The original wall heaters and floor furnaces here have heat exchangers that have cycled through 60+ winters of thermal expansion and contraction. Add salt-air corrosion attacking the cabinet from outside, and you have a failure mode that can dump carbon monoxide into living spaces without warning. We inspect with visual scopes and combustion analyzers. Replacement heat exchangers for vintage units are rarely available, so we often recommend full system replacement when we find cracks.

Trusted Brands We Service in Lomita
Whatever brand you have, we work on it. Our technicians are factory-trained or experienced on nine major HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Lomita’s newer homes with existing forced-air systems, we stock common parts for Carrier and Trane units to minimize wait times. For the vintage Wedgewood and Empire equipment still heating homes near Lomita Park and along Walnut Street, we maintain relationships with specialty suppliers who still stock or fabricate discontinued components. When parts can’t be sourced, we don’t string you along with week-long searches. We tell you immediately and move to replacement planning.
Common Heating & Furnace Problems We See in Lomita Homes
- Accelerated cabinet corrosion from marine air. Floor furnaces and wall heaters within a few blocks of Lomita’s western edge, where salt-laden air from the Port of Los Angeles penetrates inland, often show rust-through within 15–20 years. We’ve pulled units where the cabinet bottom has completely disintegrated, creating a fire hazard and draft problem.
- Cracked heat exchangers in original wall heaters. The post-war gas wall heaters in Lomita’s compact homes, many still heating bedrooms off Lomita Boulevard, develop exchanger cracks from decades of thermal cycling. Homeowners sometimes notice soot on walls or ceilings before they realize the danger. A triggered CO alarm is often the first definitive sign.
- Parts scarcity forcing repair failures. Wedgewood and Empire ignitors, gas valves, and thermocouples from the 1950s–1960s are largely discontinued. We carry some universal replacements, but many Lomita repair attempts end when we confirm the specific part no longer exists anywhere in the supply chain.
- Humidity and mold in uninsulated wall-heater cavities. Lomita’s persistent marine layer keeps humidity elevated year-round. The interior wall cavities around original gas wall heaters, never designed as conditioned spaces, accumulate condensation that breeds mold and rots surrounding framing. We see this during replacement jobs on homes near Narbonne Avenue and the older blocks off Lomita Boulevard.
Pricing for Heating & Furnace in Lomita, CA
Here’s what heating work costs in Lomita’s market. These ranges reflect real jobs we’ve completed in 90717 and nearby South Bay zip codes.
| Service | Typical Range in Lomita |
|---|---|
| Furnace Repair | $150–$700 |
| Furnace Replacement | $3,500–$7,500 |
| Tune-Up | $80–$200 |
Several factors push Lomita jobs toward the higher end of these ranges. First-time central heating installation in a home with no existing ductwork requires custom routing through tight attics, often with structural obstacles. Salt-air corrosion can fuse fasteners and require extra labor for safe removal of old equipment. And the compact footprint of Lomita’s 1950s–1960s homes, many under 1,200 square feet, means equipment must be sized precisely and installed in constrained spaces. We don’t guess. Jason Trent measures on-site and provides itemized quotes before any work begins. Estimates are free. Call (855) 467-1888.

FAQs — Heating & Furnace in Lomita
Sometimes, but parts availability is the limiting factor. Wedgewood pilot assemblies, thermocouples, and gas valves from the 1960s are largely discontinued, and universal replacements don’t always fit the specific mounting configurations. We carry some compatible components and will attempt the repair if the part exists, but we’ve learned not to promise what we can’t source. If the repair isn’t feasible, we’ll quote replacement options same-day. Call (855) 467-1888 and we’ll check our stock against your model number.
In most Lomita bungalows, yes, the attic is the only practical path for ductwork. These homes were built without interior cavities designed for forced-air distribution. We route flexible duct between existing trusses, sizing runs to maintain airflow in compact 1,000–1,200 square foot layouts. On some jobs, particularly homes with severely limited attic clearance, we may recommend a ductless mini-split heat pump instead. Jason Trent evaluates each structure personally before we commit to either approach. Estimates are free.
Once yearly, ideally before the heating season begins in November. Lomita’s marine-layer humidity creates year-round condensation inside uninsulated wall-heater cavities, accelerating corrosion and creating mold conditions that a standard combustion check won’t catch. Annual service includes heat exchanger inspection, gas pressure testing, and cabinet integrity assessment. For homes with original 1950s–1960s equipment, we sometimes recommend bi-annual checks given the age-related failure risk. A tune-up runs $80–$200. Call (855) 467-1888 to schedule.
Rust on a furnace cabinet can progress from cosmetic to hazardous faster in Lomita than inland because salt-laden air accelerates corrosion. Surface rust warrants monitoring. Rust-through, where the metal has perforated and created gaps in the combustion chamber enclosure, is a fire and carbon monoxide hazard requiring immediate replacement. We inspect cabinet integrity, burner alignment, and heat exchanger condition during any service call. Don’t wait for a CO alarm to tell you something’s wrong. Call (855) 467-1888 for an inspection.
Usually, replacement is the smarter investment. A gas valve repair on a 50-year-old Empire or Wedgewood runs $150–$400 in parts and labor, but the unit still has a cracked heat exchanger, corroded cabinet, and obsolete components waiting to fail next. We’ve done the math with Lomita homeowners: one repair often leads to another within a season or two, and total spending approaches half the cost of a new system with none of the efficiency or safety gains. Modern 95% AFUE gas furnaces cut fuel use dramatically. We quote both options honestly, but we don’t recommend throwing good money at equipment that’s past its design life. Call (855) 467-1888 for a free replacement estimate.
