Fast, Reliable Heating & Furnace Across North Hills
Heating and furnace repair in North Hills typically runs $175–$825 depending on the part and labor involved, and most calls we handle in the 91343 and 91393 ZIP codes are completed same day. North Hills sits on the inland San Fernando Valley floor where winter overnight lows can dip to the mid-30s, and when your furnace fails on a January morning, you need a technician who knows these 1950s–1960s tract homes inside and out. We’re Heating & Furnace specialists who work this corridor regularly, and Daniel Okafor personally handles the diagnostics and repair on every call. For emergency furnace service in North Hills, call us at (855) 600-3322.
Why Northstar Heating & Air San Francisco Is North Hills’s Preferred Heating & Furnace Company
North Hills homeowners have left us 357 verified reviews averaging 4.9 stars, and a significant share of those come from repeat customers in the 91343 ZIP who first called us after a cold snap left their original furnace dead. Daniel Okafor doesn’t send a rotating crew — he’s the owner and the lead technician on your job, which means the person quoting the work is the same person standing in your attic tracing a cracked heat exchanger.
Our response time to North Hills averages under 90 minutes for emergency heating calls because we know the grid: Roscoe Boulevard to Nordhoff Street, the residential pockets tucked behind Sepulveda Boulevard, the commercial strips near Parthenia Street. We’ve replaced ignitors in January frost on Lassen Street and sealed leaking plenums in the attic cavities above Haskell Avenue homes where 1960s duct tape has turned to dust.
That local knowledge matters. North Hills’s post-WWII housing stock wasn’t built for modern HVAC demands, and a technician who treats this like generic suburban LA will miss the telltale signs: slab foundations that complicate gas line routing, low-pitch roofs that trap attic heat against ductwork, earthquake-era patchwork repairs from the mid-1990s that are now themselves failing. Daniel has spent a decade reading these houses, and that experience shows up in faster diagnoses and repairs that actually last.
Our Heating & Furnace Services in North Hills
Furnace Repair in North Hills
When your furnace quits on a 38°F North Hills morning, you don’t have time for a dispatcher to “check availability.” Daniel answers directly, and most repairs on Carrier, Trane, Lennox, Goodman, and Rheem units are completed in a single visit. Common calls here include failed ignitors from thermal cycling stress, gas valves corroded by decades of Valley dust, and blower motors straining against collapsed return plenums in those original 1960s systems. A typical furnace repair in North Hills runs $175–$825. We stock ignitors, flame sensors, and gas valves for the brands we service, so you’re not waiting days for a part.

Furnace Replacement in North Hills
Many North Hills homes still run furnaces installed during the 1994–1996 post-earthquake rebuild wave, and at 28–30 years old, those units are past design life and operating at 60% efficiency or worse. Replacement isn’t just about swapping boxes — it’s about right-sizing for a house whose original load calculation assumed a different climate reality. We measure heat loss through those uninsulated slab perimeters, account for the ductwork damage that’s standard in 91343 attics, and spec equipment that won’t short-cycle or overwork. Furnace replacement pricing in North Hills starts around $4,130 for a standard-efficiency unit and ranges to $8,850 for high-efficiency systems with full duct remediation.

Furnace Tune-Up in North Hills
A furnace tune-up in North Hills costs $95–$235 and should happen every fall before the first cold snap. Our tune-up includes combustion analysis, heat exchanger inspection with a borescope, gas pressure verification, and airflow measurement at each supply register. In North Hills specifically, we pay extra attention to the condition of attic duct connections — that desiccated cloth-backed tape is so common in 1960s tracts here that we carry foil-backed mastic and mechanical fasteners on every truck. Catching a cracked heat exchanger or CO leak before you fire the system for winter isn’t optional in a house with original construction.

Heat Exchanger Inspection & Replacement in North Hills
Cracked heat exchangers are a genuine safety hazard — they can leak carbon monoxide into your living space, and this is not a DIY diagnosis. In North Hills, we find this failure mode most often in furnaces that have been oversized for decades, cycling on and off thousands of times per season, or in units where restricted airflow from collapsed ductwork has caused chronic overheating. Daniel uses a digital borescope to inspect every heat exchanger during service calls, and if replacement is needed, we’ll show you the footage and explain your options clearly. Heat exchanger replacement typically falls in the upper half of our $175–$825 repair range depending on accessibility and brand.

Common Heating & Furnace Problems We See in North Hills Homes
- Failed ignitors in original 1990s furnaces. The post-Northridge earthquake replacement wave installed thousands of furnaces in 91343 and 91393 that are now at end of life. Ignitor failure is often the first sign the system’s components are fatiguing across the board.
- Heat exchanger cracks from decades of oversizing. Many North Hills furnaces were spec’d larger than necessary to “be safe,” but oversizing causes short cycling, thermal stress, and eventually metal fatigue in the exchanger — a CO risk that demands immediate attention.
- Attic ductwork losing 25–40% of heated air before it reaches rooms. The cloth-backed tape used in 1960s North Hills tract construction hasn’t survived six decades of 150°F summer attic peaks. We find open seams and disconnected branches on nearly every original system we open.
- Gas valve failures from accumulated Valley dust and corrosion. North Hills’s inland location means finer particulate and wider temperature swings than coastal LA, and original gas valves often seize or leak after 20+ years of exposure.
