We’re Northstar Heating & Air, and while our roots are in San Francisco, our Heating & Furnace team regularly serves Los Angeles homeowners and businesses across ZIPs 90030, 90031, 90032, and 90033. Daniel Okafor, our owner and lead technician, personally handles the diagnostic and repair work on every job we take in Los Angeles. You get the person whose name is on the truck, not a rotating subcontractor who disappears when something goes wrong. Call (855) 600-3322 for a free estimate or same-day service.
Why Northstar Heating & Air San Francisco Is Los Angeles’s Preferred Heating & Furnace Company
Our reputation in Los Angeles has grown through word-of-mouth from customers in Koreatown, Echo Park, and Silver Lake who needed furnace work done right the first time. 357 customers have left verified reviews averaging 4.9 stars, and a growing share of those come from Los Angeles referrals — people who initially hesitated to call a San Francisco-based company until they realized Daniel personally travels for complex jobs and coordinates a trusted local crew for routine service.
Response time to Los Angeles averages under 90 minutes for emergency calls placed before 6 PM, and we schedule next-day appointments for non-urgent furnace tune-ups throughout Central and South LA. We know the local terrain: the narrow streets around Sunset Boulevard in Silver Lake, the hillside access challenges in View Park-Windsor Hills, and the parking logistics that slow down less experienced technicians. That local knowledge translates to faster arrivals and fewer “we’ll need to come back” situations.
What separates us from Los Angeles HVAC franchises is accountability. When Daniel Okafor is your technician, the owner is the one crawling into your crawl space, reading your gas valve pressure, and standing behind the repair. No dispatcher. No crew rotation. No passing the buck if something isn’t perfect.
Our Heating & Furnace Services in Los Angeles
Furnace Repair
Furnace repair in Los Angeles runs $175–$825 depending on the part and accessibility. In the 1920s craftsman bungalows and Spanish Revival duplexes that dominate ZIPs 90030–90033, furnaces are often crammed into converted closets or basement corners with no working clearance, which adds diagnostic time. We carry ignitors, gas valves, flame sensors, and control boards for Goodman, Rheem, and York systems on our vans, so most Los Angeles furnace repairs finish in a single visit.
Furnace Replacement
When a heat exchanger cracks or repair costs exceed half the value of a 15-year-old unit, replacement becomes the smarter call. Los Angeles furnace replacement is complicated by what the LA Department of Building and Safety requires: seismic anchoring and flexible gas-line connectors on all new equipment, a legacy of the Northridge earthquake that out-of-state contractors routinely miss. We’ve handled these permits dozens of times. Daniel personally measures your existing footprint, specifies the right Rheem or Daikin unit for your square footage, and manages the inspection schedule so you’re not left without heat.
Furnace Tune-Up
A furnace tune-up in Los Angeles costs $95–$235 and should happen every fall before the first cold snap. Even in mild Mediterranean climates, dust accumulation from Santa Ana wind events and wildfire smoke seasons degrades blower motors and clogs filters faster than coastal San Francisco conditions. Our tune-up includes combustion analysis, gas pressure verification, heat exchanger inspection with a borescope, and filter sizing for MERV-13 or better if you’re upgrading for air quality. In courtyard apartment buildings with shared mechanical access, we coordinate with property managers to minimize tenant disruption.
Heat Exchanger Inspection & Replacement
Cracked heat exchangers are a genuine safety hazard — they leak carbon monoxide into living spaces, and in the tight floor plans of Los Angeles courtyard apartments and duplexes, that risk concentrates fast. We inspect with visual borescope and combustion testing; if replacement is needed, we source OEM heat exchangers for Goodman, Rheem, and York units rather than universal-fit aftermarket parts that fail early. Given the permit and gas-line work involved, heat exchanger replacement in Los Angeles typically runs at the higher end of our repair range.

Trusted Brands We Service in Los Angeles
We’re certified and experienced on nine major HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Los Angeles customers, that means no referral runarounds when your system is a Daikin modulating furnace or a York two-stage unit — we stock common parts locally and can source same-day or next-day for less common components. Rheem and Goodman parts move fastest in the Los Angeles market given their prevalence in 1990s–2010s retrofits, and we keep ignitors, gas valves, and control boards for both on our service vans.
Common Heating & Furnace Problems We See in Los Angeles Homes
- Pilot light failures during Santa Ana wind events. The sudden pressure drops and gusts through older venting systems blow out standing pilots in pre-1990 furnaces, especially in hillside neighborhoods like Echo Park where wind tunnels between buildings amplify the effect. We upgrade to electronic ignition where possible.
- Heat exchanger cracks in 30-year-old floor furnaces. Many 1920s–1950s Los Angeles homes still rely on original floor furnaces with no ductwork; these units rust from decades of ground moisture and seismic settling, and replacement requires navigating Title 24 energy compliance with no existing mechanical infrastructure.
- Short-cycling from oversized replacement furnaces. Previous contractors in Los Angeles often installed furnaces rated for colder climates, causing rapid on-off cycles that waste gas and fail to destratify air in high-ceilinged Spanish Revival living rooms. We size properly using Manual J load calculations.
- Gas valve corrosion from coastal moisture infiltration. Even inland Los Angeles neighborhoods get marine layer push some mornings; combined with aging flex connectors that predate current seismic codes, this creates slow gas leaks we detect during routine service calls in View Park-Windsor Hills and surrounding areas.

What moves you within these ranges? Accessibility is the big variable in Los Angeles. A furnace in a dedicated utility room with 30 inches of clearance takes an hour less labor than one wedged under a stairwell in a 1930s Koreatown duplex. Seismic bracing and flexible gas connectors add material cost that flat-rate national pricing tools ignore. We quote upfront after inspection, not after work begins. Call (855) 600-3322 for a free estimate — we’ll give you a firm number you can compare.

FAQs — Heating & Furnace in Los Angeles
We typically arrive within 90 minutes for emergency heating calls placed before 6 PM in ZIPs 90030–90033, and we offer after-hours emergency HVAC service for urgent no-heat situations. After 6 PM, response time extends to 2–3 hours depending on traffic patterns along the 101 and surface streets. Call (855) 600-3322 and we’ll give you a real ETA, not a window.
We actively serve 90030, 90031, 90032, and 90033, with regular calls from Koreatown, Echo Park, Silver Lake, and View Park-Windsor Hills. For furnace replacement or complex diagnostics, Daniel Okafor personally travels from San Francisco to Los Angeles; for routine tune-ups, our coordinated local crew handles the appointment. Call to confirm coverage for your specific address.
Labor rates in Los Angeles run roughly 10–15% above the national average, but our pricing stays consistent with our San Francisco rates — we don’t inflate for travel. The bigger cost driver is local code compliance: LA Department of Building and Safety requires seismic anchoring and flexible gas connectors that add $200–$400 in materials and permit fees compared to markets without earthquake retrofit rules. We include these in our upfront quotes.
All furnace repairs carry a one-year parts and labor warranty, and replacement installations include manufacturer warranties that range from 5 to 10 years depending on the Rheem, Daikin, or Goodman model selected. Our 4.9-star average across 357 reviews reflects how we handle the rare warranty callback — Daniel personally follows up, not a service department.
Replace if your furnace is over 15 years old and the repair exceeds $500, or if the heat exchanger is cracked — that’s a safety issue no repair fixes. Repair if the unit is under 12 years old and the problem is a single failed component like an ignitor or gas valve. In Los Angeles’s pre-1955 housing stock, replacement often requires ductwork and gas line modifications that push the project toward the higher end of our $4,130–$8,850 range, so we only recommend it when the math genuinely favors it. Call (855) 600-3322 for an honest assessment — estimates are free.
