North Hollywood sits in a tough spot, geographically speaking. The eastern San Fernando Valley floor acts like a heat sink, with summer temperatures hitting 105–110°F while coastal LA stays 10–12°F cooler just 20 miles away. Most homes here were built between the 1950s and 1970s with gas wall heaters and evaporative coolers, not central forced-air systems. That means when your heat goes out in January or you’re finally done with that ancient wall heater, you’re not looking at a simple swap. You’re looking at a full HVAC retrofit into a building that was never designed for ductwork. We’ve been handling exactly these jobs for 13 years.
Our Heating & Furnace team knows the 91605 and 91606 corridors well, from the apartment clusters near Magnolia Boulevard to the post-war tract homes south of Burbank Boulevard. Parking’s tight, alleys are narrow, and access windows are small. We plan for that.
Why Redwood Heating & Air San Diego Is North Hollywood’s Preferred Heating & Furnace Company
Gregory Hahn founded this company and still leads every technical decision. That matters in North Hollywood, where a furnace retrofit isn’t a cookie-cutter install. You need someone who can look at a 1962 stucco ranch with no duct chases and know exactly how to route supply and return without tearing apart walls.
Our 428 verified reviews averaging 4.6 stars include plenty from North Hollywood homeowners who’ve dealt with exactly this scenario. They mention our crew showing up on time to tight alley-access jobs, working around tenant schedules in multi-family buildings, and explaining why their old wall heater cracked a heat exchanger after 40 years of thermal cycling.
Response time to North Hollywood runs same-day for most calls placed before noon, next-morning for afternoon requests. We carry common furnace parts for Carrier, Trane, and Bryant systems on our trucks, which cuts wait time when your furnace locks out on a cold night.
The valley geography creates problems coastal techs rarely see. Attic temperatures above 150°F in summer accelerate duct insulation breakdown and refrigerant line degradation. Fall Santa Ana wind events spike heating demand sharply, causing undersized furnaces to short-cycle or trip high-limit switches. We’ve diagnosed these patterns across North Hollywood for over a decade.
Our Heating & Furnace Services in North Hollywood
Furnace Repair
Furnace repair in North Hollywood ranges from $150–$700 depending on the component and accessibility. We see a lot of ignitor failures in 1970s-era furnaces that were never meant to cycle as often as valley temperature swings demand. Gas valve issues are common too, especially in converted wall-heater systems where the original gas line sizing doesn’t match the new furnace’s BTU load. Our technicians carry replacement ignitors, flame sensors, and gas valves for Carrier, Trane, and Bryant systems on every truck.
Furnace Replacement
Full furnace replacement in North Hollywood runs $3,500–$7,500, with most retrofits from wall heaters landing in the upper half of that range due to ductwork and gas line modifications. This is our most-called service in the 91605 and 91606 zip codes. We retrofitted a two-story dingbat on Vineland Avenue in 91606, swapping a wall heater for a 96% AFUE Carrier gas furnace. Our crew snaked new ductwork through a 130°F attic and ran a gas line through a shared alley chase, all while ensuring the homeowner’s rolling-code garage opener stayed secure. That job took three days. Most standard replacements take one.
Furnace Tune-Up
A furnace tune-up in North Hollywood costs $80–$200 and should happen every fall before Santa Ana season hits. We check heat exchanger integrity, gas pressure, flame rollout, and limit switch function. In this market, we pay special attention to thermal expansion cracks in older heat exchangers and blower motor strain from undersized return ducts in retrofit installations. Catching a cracked heat exchanger before heating season starts can save you from a mid-winter emergency call and potential carbon monoxide exposure.
Heat Exchanger Inspection & Replacement
Heat exchanger failure is the endgame for most wall heaters and older furnaces in North Hollywood. Decades of thermal cycling, combined with valley attic temperatures that swing from 40°F winter nights to 150°F summer afternoons, create metal fatigue that coastal climates simply don’t produce. We inspect heat exchangers with borescope cameras and combustion analyzers. Replacement heat exchangers are available for Carrier and Trane units we commonly see here; some 1960s wall heater models are beyond parts availability and require full system replacement.
Ignitor Replacement & Gas Valve Repair
Hot surface ignitors fail every 3–5 years in heavy-use valley systems. Gas valves can stick or leak, particularly in retrofitted installations where line pressure wasn’t properly adjusted for the new furnace’s manifold pressure requirements. We stock both components for major brands and can typically complete these repairs in a single visit.

Trusted Brands We Service in North Hollywood
We service your brand, whatever it is. Our technicians are factory-trained or field-experienced across nine major HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. In North Hollywood, we see a lot of Carrier and Bryant systems in 1990s-era homes that were among the first in the neighborhood to get central air retrofits. Trane furnaces show up frequently in 2000s condo conversions along Lankershim Boulevard. We stock common ignitors, flame sensors, and control boards for these brands locally, which means faster turnaround when your heat goes out on a 45°F January morning.
Common Heating & Furnace Problems We See in North Hollywood Homes
- Cracked heat exchangers in 1960s wall heaters. The original gas wall heaters in North Hollywood’s post-war tract homes weren’t designed for 60 years of thermal cycling. Valley attic temperatures that hit 150°F in summer accelerate metal fatigue. We find hairline cracks with borescope inspection; replacement usually means full furnace retrofit since parts are obsolete.
- Santa Ana wind short-cycling. Fall Santa Ana events spike temperatures rapidly, causing furnaces to cycle on and off repeatedly. Undersized systems or those with dirty filters hit high-limit switches and lock out. We see this most in 91605 apartment buildings where original furnaces were sized for milder coastal assumptions.
- Gas line leaks at retrofit joints. Running new gas lines through tight stucco clearances in alley-load buildings gets pinch points and unbrazed joints that leak under pressure. We pressure-test every retrofit installation and use flexible gas connectors rated for the movement these old buildings settle into.
- Blower motor failure from restricted returns. Retrofit ductwork in homes without original chases often uses undersized return paths. The blower works harder, runs hotter, and fails prematurely. We measure static pressure and resize returns when we find this on tune-ups.

FAQs — Heating & Furnace in North Hollywood
Yes, we regularly convert wall-heater apartments to central gas furnace systems by routing flexible ductwork through attics, closets, and soffits built specifically for the retrofit. In North Hollywood’s 1950s–70s buildings, we snake supply lines through existing attic spaces and use high-velocity mini-duct systems where clearance is too tight for conventional ductwork. Call (844) 875-9451 and we’ll survey your specific layout.
Santa Ana wind events cause rapid temperature spikes that force your furnace to cycle frequently, which can trip high-limit safety switches on older or undersized units. We see this most in 91605 apartment buildings with original equipment sized before valley heat extremes were fully understood. A tune-up that verifies limit switch function and checks for proper airflow prevents most Santa Ana-season lockouts.
The limit switch trips because your furnace is overheating, and at 60 years old the most likely cause is a cracked heat exchanger or restricted airflow from decades of dust accumulation in an undersized return path. In North Hollywood’s post-war housing stock, we find that original wall heaters and early furnaces were installed with minimal return air capacity. We diagnose with combustion analysis and static pressure testing; replacement is usually the safest option given the age.
In most 91601 townhouse configurations, we can route gas lines through existing attic spaces, crawl areas, or shared utility chases without opening finished walls. We pressure-test every joint and use flexible connectors where building settlement is a factor. An on-site survey lets us map the exact path for your specific unit.
A full furnace and ductwork installation in a 1974 North Hollywood home typically runs $5,500–$9,500 depending on square footage, attic accessibility, and whether we can use existing chases or must build new soffits and closet drops. Homes from this era in the 91606 zip code often have cramped attics and dense stucco that slow retrofit work. We provide itemized estimates after a site survey. Call (844) 875-9451 to schedule.
