We don’t send rookies to figure out your system on the clock. Jason Trent, our owner, holds the title of Field Supervisor and personally oversees jobs. That means experienced, accountable hands on every Los Angeles project, whether we’re replacing a cracked heat exchanger in Echo Park or troubleshooting gas valve issues in a Silver Lake townhome with alley-only access.

Why Stonegate Heating & Air California Is Los Angeles’s Preferred Heating & Furnace Company

Los Angeles homeowners have left us 499 verified reviews averaging 4.7 stars, and a lot of that feedback comes from customers in ZIP codes 90030 through 90033 who were tired of explaining their floor furnace to techs who’d never seen one. We’ve been at this 16 years. We know the difference between a Craftsman cottage in View Park-Windsor Hills and a courtyard building off Alvarado, and we know how to heat both without tearing the place apart.

Jason Trent doesn’t run this company from a back office. He’s Field Supervisor, which means he’s on job sites, checking access clearances, verifying heat exchanger installations, and making sure our team isn’t cutting corners on Title 24 compliance or SCAQMD Rule 1111 requirements that every permit-pulled furnace job in Los Angeles must meet. California’s energy code demands HERS field verification and duct-leakage testing on new installations. That’s paperwork and process that contractors across state lines never touch, but it’s standard practice for us on every Los Angeles job.

Our multi-brand fluency matters here too. Los Angeles homes run Carrier, Trane, Lennox, Goodman, and more — whatever brand you have, we’ve worked on it. Nine brands, one team. No “we don’t service that” dead ends.

Our Heating & Furnace Services in Los Angeles

Furnace Repair

Most Los Angeles furnace repair calls we get aren’t about central furnaces at all. They’re floor furnaces with pilot lights blown out by drafty crawl spaces, or wall heaters choked with decades of dust from Santa Ana wind events. A typical furnace repair in Los Angeles runs $175–$825 depending on access difficulty and parts. Tight urban lots mean we sometimes spend extra time maneuvering equipment through side gates or basement hatches, but we quote upfront so you know before we start.

Furnace Replacement

This is where Los Angeles gets complicated — and where our experience pays off. Millions of homes across central Los Angeles, particularly the 1920s–1950s bungalows and courtyard apartments dense in ZIP codes like 90004, 90006, and 90007, were built without any ductwork because the historically mild Mediterranean climate made central HVAC unnecessary. Retrofitting these homes for modern heating means designing first-ever duct systems or specifying ductless mini-split systems, a fundamentally different job scope than simple equipment swaps. We recently replaced a failing floor furnace in a 1930s bungalow on 3rd Street in the 90004 area with a ductless mini-split system. The original unit was unsafe and inefficient, and we installed a Mitsubishi unit with line-sets hidden in the attic, ensuring the home stayed warm during a surprise Santa Ana cold snap. Furnace replacement in Los Angeles requires navigating Title 24 compliance, SCAQMD Rule 1111 low-NOx requirements, and often creative duct routing through shallow crawl spaces or attic drops.

Furnace Tune-Up

A furnace tune-up in Los Angeles costs $95–$235 and should happen annually, ideally before Santa Ana season kicks in September through November. For floor furnaces and wall heaters, this means cleaning dust-clogged burners, testing gas valve operation, checking heat exchanger integrity for cracks that could leak carbon monoxide into living spaces, and verifying proper venting in tight crawl spaces where airflow is already compromised. Many Los Angeles homeowners skip maintenance because “we barely use heat,” but that neglect is exactly why ignitors fail and gas valves lock out when that first cold snap hits.

Heat Exchanger Inspection & Replacement

Cracked heat exchangers are a safety issue we take seriously, especially in Los Angeles’s older housing stock where furnaces and floor heaters have been cycling on and off for 30-plus years. The urban heat island effect in inland South Central and Koreatown ZIP codes pushes systems harder than beach-adjacent properties, accelerating metal fatigue. We inspect heat exchangers with visual and combustion analysis tools, and if replacement is needed, we handle the full scope including permit pulls and HERS verification required by Los Angeles building codes.

Gas Valve Repair

Gas valve lockouts are common in Los Angeles floor furnaces when pilot lights repeatedly fail, and in wall heaters where sediment from decades of service affects valve operation. We don’t just swap parts — we diagnose why the valve failed, whether it’s draft pressure, thermocouple degradation, or gas pressure issues specific to your neighborhood’s infrastructure. Proper gas valve repair restores safe, reliable operation without the cost of full replacement when it’s not needed.

Ignitor Replacement

Hot surface ignitors in modern furnaces and spark ignitors in older wall heaters both fail with age. Los Angeles’s dry Santa Ana conditions can accelerate ceramic degradation. We stock common ignitor types and can match replacements across our nine supported brands, minimizing downtime when your heat goes out.

Trusted Brands We Service in Los Angeles

We maintain familiarity with nine major HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Los Angeles customers, this means we don’t waste time sourcing parts or guessing at wiring diagrams. We’ve worked on Goodman wall heaters in Koreatown apartments, Trane central systems in Silver Lake renovations, and Carrier retrofits throughout the 90001–90010 corridor. Whatever brand you have, we likely have the field experience and parts relationships to fix it fast.

Common Heating & Furnace Problems We See in Los Angeles Homes

• Floor furnace pilot lights that won’t stay lit. Drafty crawl spaces in pre-1950 bungalows let wind extinguish pilots, causing gas valve lockout. The shallow or slab-on-grade construction common in the 90001–90010 corridor makes sealing these drafts difficult without professional assessment.
• Wall heaters cycling on and off or failing to ignite. Decades of dust buildup from Santa Ana wind events, combined with worn ignitors and neglected maintenance, leave these units unreliable. Most Los Angeles apartment owners don’t realize wall heaters need annual service until tenants complain.
• Heat exchanger cracks in aging floor furnaces. Metal fatigue from decades of thermal cycling, worsened by Los Angeles’s urban heat island pushing afternoon temperatures higher, creates dangerous carbon monoxide risks in homes with poor ventilation.
• Gas valve failures due to sediment and pressure issues. Original gas valves in 1920s–1950s systems corrode internally, and Los Angeles’s varying neighborhood gas pressures can cause erratic operation that mimics other failures.
