Fast, Reliable AC Repair & Installation Across Tujunga
When your AC quits on a 102°F Santa Ana afternoon in Tujunga, you don’t have time to wait for a dispatcher in Van Nuys to figure out where Big Tujunga Canyon meets Foothill Boulevard. We’re already here. Our AC Repair & Installation team covers the full 91042 and 91043 ZIP codes with same-day response, and Daniel Okafor personally handles every call, every diagnosis, and every install. Call (855) 600-3322 for a free estimate.
AC repair in Tujunga typically costs $175–$765 and is often completed same day. Installation runs $4,130–$8,850 depending on home size, existing ductwork condition, and whether your property falls under LA’s Very High Fire Hazard Severity Zone requirements. We’re familiar with both.
Why Northstar Heating & Air San Francisco Is Tujunga’s Preferred AC Repair & Installation Company
Daniel Okafor has spent 10 years building Northstar into an owner-operated HVAC company where the person answering your questions is the same technician wiring your thermostat. That matters in Tujunga, where the canyon geography, VHFHSZ fire codes, and post-war housing stock create problems that out-of-area crews misdiagnose or overlook entirely.
Our 4.9-star rating across 357 verified reviews reflects customers who got the boss on their job, not a rotating subcontractor. Tujunga homeowners in the foothills near Mount Gleason Avenue and the post-war neighborhoods off Commerce Avenue have left consistent feedback about Daniel’s willingness to explain why their 1950s ranch needs different duct routing than a new build in Burbank would.
Response time to Tujunga averages under 90 minutes for emergency calls. We don’t route through a central valley hub. We know that a failed compressor on a 100°F day in the 91042 ZIP isn’t a comfort issue, it’s a health issue for elderly residents and young children in hillside homes without basements.
We also handle Heating & Furnace in Tujunga and Heat Pump & Mini Split in Tujunga, which matters here more than most LA neighborhoods. At 1,500–2,000 feet elevation, Tujunga runs 5–10°F colder on clear winter nights than the San Fernando Valley floor below. Homes that need serious cooling in September need real heating in January. One company, both systems, one technician who remembers your house.
Our AC Repair & Installation Services in Tujunga
AC Repair
Tujunga’s Santa Ana wind events funnel straight down Big Tujunga Canyon, packing condenser coils with ash, pine needles, and debris from the Angeles National Forest. We’ve replaced compressors on York and Daikin units that failed prematurely because the previous technician never checked coil fouling. A typical AC repair in Tujunga runs $175–$765. Daniel personally diagnoses every system, checks refrigerant levels, electrical connections, and whether your outdoor unit’s pad is secured against wind shear.
AC Installation
New AC installation in Tujunga starts at $4,130 and ranges to $8,850 for full split systems in larger hillside homes. Every install we do in the 91042 ZIP includes LA LADBS ember-resistant vent screening, 1/16-inch mesh on attic and foundation vents. Plan checkers here flag missing ember guards as a VHFHSZ deficiency, and out-of-area contractors routinely overlook this. We don’t. We size systems for Tujunga’s dual climate, where winter lows and summer spikes both demand full-capacity equipment.
AC Replacement
Most Tujunga homes were built between the late 1940s and mid-1960s with wall furnaces or gravity floor heat, not ducted forced-air. Replacing an aging AC in these houses often means discovering deteriorated early flex ductwork in tight attics with low pitch. We’ve rerouted ducting through closets and soffits in ranch homes near Oro Vista Avenue that had no viable attic path. Replacement costs match installation ranges, but we always inspect existing ductwork first so you’re not surprised mid-project.
Refrigerant Recharge
Low refrigerant in Tujunga usually means a leak, not normal consumption. The temperature swings between canyon-cold nights and Santa Ana-heated days stress copper linesets, especially where they pass through Tujunga’s aging foundations and seismic-shift-prone soil. We pressure-test every system before adding refrigerant. A recharge alone runs $175–$400 depending on refrigerant type and system size, but we’ll show you exactly where the leak is before you spend a dollar on gas that’ll just escape again.

Trusted Brands We Service in Tujunga
We maintain direct experience on nine major HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Tujunga customers, this means no referral runarounds when your Daikin mini split throws a code or your Bryant condenser won’t start. We stock common capacitors, contactors, and refrigerants for these brands locally, so most repairs don’t wait on parts delivery. Daniel’s certified to work on all nine, which matters when you’re trying to keep a 20-year-old American Standard alive for one more season or deciding whether a new York system makes sense for your foothills home.
Common AC Repair & Installation Problems We See in Tujunga Homes
- Wind-damaged outdoor units. The Big Tujunga Canyon acts as a wind tunnel during Santa Ana events, and we’ve found condensers tilted on unsecured pads or with bent fan blades from debris impact. We anchor every unit we install with earthquake-rated mounting, not just standard pads.
- Ember-vent code failures on resale inspections. LA LADBS plan checkers in the 91042 ZIP consistently flag missing or undersized ember guards on attic HVAC vents as a VHFHSZ deficiency. We install compliant 1/16-inch mesh screening as standard on every duct job, not as an upsell.
- Ductwork deterioration in post-war attics. Tujunga’s 1940s–1960s housing stock often contains original sheet-metal or early flex duct that has aged poorly in canyon temperature swings. We find collapsed runs and disconnected returns in homes near Foothill Boulevard that explain why the AC runs constantly but rooms stay hot.
- Undersized systems for dual-climate demand. Because Tujunga sits 1,500–2,000 feet up, it needs real heating and real cooling. Contractors who size for flat-valley LA conditions install equipment that struggles on both ends. We perform Manual J load calculations that account for foothills elevation and canyon wind exposure.

FAQs — AC Repair & Installation in Tujunga
We typically arrive within 90 minutes for emergency calls in the 91042 and 91043 ZIP codes. Daniel Okafor handles every emergency personally, so there’s no dispatcher relaying messages between you and a technician who doesn’t know your area. Call (855) 600-3322 and we’ll give you a real ETA based on current traffic from our route into the foothills.
Yes, we service the full Tujunga area, from the flat neighborhoods near Foothill Boulevard and Commerce Avenue up to the steeper parcels near Mount Gleason and the canyon edges. We’ve installed systems in tight hillside lots where equipment had to be craned in, and we’ve repaired units in post-war ranches with original ductwork that hasn’t been touched since 1955.
Repair labor rates are comparable, but Tujunga jobs sometimes require additional code compliance for the Very High Fire Hazard Severity Zone, specifically ember-resistant vent screening on attic and foundation vents. This adds material cost to installations and major duct replacements, not typically to simple repairs. We include these requirements in every quote so you’re not surprised by a LADBS inspection failure later.
Same-day installation is possible for straightforward replacements where existing ductwork and electrical are in good condition. Most full installs require one to two days, especially in Tujunga’s older homes where we discover deteriorated ductwork or need to engineer new routing through small attics. We’ll tell you exactly which category your home falls into during the free estimate.
We warranty all labor for one year and pass through manufacturer warranties on equipment, which range from 5 to 10 years depending on brand and model. For Tujunga customers, this means Daniel Okafor’s personal accountability backs every install, not a corporate warranty department you’ll never reach. If something isn’t right, you call the same person who did the work.
