We’re Northstar Heating & Air, and Daniel Okafor personally handles every call that comes out of the 90603 area. If your compressor just seized up on a July afternoon along Santa Gertrudes Avenue, or your wall-mounted unit from the 1980s finally gave out near East Road, you’re not waiting on a dispatcher to find a tech. You’re talking to the owner, who’s also the lead technician, and who’s been driving these streets for ten years. We know the difference between a quick capacitor swap on a newer Rheem and a full retrofit through a 1962 ranch attic where the original builder never imagined central air.
Call (855) 600-3322. Daniel answers directly, and we’ll get you scheduled.
Why Northstar Heating & Air San Francisco Is East La Mirada’s Preferred AC Repair & Installation Company
East La Mirada sits in that tricky inland pocket where the Puente Hills block the marine layer, so summer afternoons hit harder here than in Whittier or South Whittier just a few miles west. We’ve learned that a system charged to “standard” coastal specs will underperform in your neighborhood. Daniel calibrates every install and recharge for your actual microclimate, not a textbook average.
Our AC Repair & Installation team has built a 4.9-star reputation across 357 verified reviews by showing up when we say we will and fixing it right the first time. East La Mirada customers specifically mention our response time in their feedback, we’re usually on-site within hours, not days, because we’re not routing crews from a dispatch center thirty miles away.
Because Daniel is both owner and lead technician, the person who quotes your job is the same person who performs it. No handoffs. No “the other guy said…” situations. In unincorporated LA County, where permits run through county building and safety instead of a local city hall, that accountability matters. We’ve learned to pull permits with inspection slots already reserved, avoiding the backlogs that stall less experienced contractors.
Our AC Repair & Installation Services in East La Mirada
AC Repair
When your Goodman or York starts blowing warm air in August, we’ll diagnose it on the spot. Most East La Mirada repairs involve capacitors, contactors, or refrigerant leaks, and we stock common parts so you’re not waiting on a warehouse run. Because so many local homes have retrofitted ductwork from the 1980s and 90s, we also check whether your “AC problem” is actually an airflow problem, crushed flex duct in a hot attic is a pattern we see repeatedly in the ranch-style tracts near Leffingwell Road.

AC Installation
New system installs in East La Mirada are rarely straightforward swap-outs. The 1955–1970 Lakewood-era homes that dominate this area were built for wall or floor furnaces, with no chases, soffits, or generous attic clearances. Daniel has routed ductwork through tight crawl spaces and low-pitch roofs from Santa Gertrudes to the edge of La Habra, and we size every system for the actual heat load your home experiences, hotter afternoons, Santa Ana winds, and all.

AC Replacement
If your compressor failed or your system uses phased-out R-22 refrigerant, replacement often makes more sense than repair. We handle full removals and upgrades, including electrical panel upgrades when your 1960s service can’t support modern equipment. Because East La Mirada permitting flows through LA County Building & Safety, we coordinate inspections from permit pull, not after rough-in, keeping your project on schedule.

Refrigerant Recharge & Leak Repair
Low refrigerant means a leak, period. We locate and repair the source before recharging, because topping off a leaking system is throwing money away. In East La Mirada’s hotter microclimate, an undercharged system works overtime, shortening compressor life. We use electronic leak detection and pressure testing, then recharge to manufacturer spec adjusted for your actual operating conditions, not a generic chart.
We also handle Heat Pump & Mini Split in East La Mirada for homes where ductless zoning makes more sense than forcing central air through improvised duct runs.

Nine major brands, one company, and the same technician from quote to completion.
Common AC Repair & Installation Problems We See in East La Mirada Homes
- Undersized retrofitted ductwork collapsing in attics. The 1980s–90s central-air retrofits in these Lakewood-era ranches often used flex duct routed through spaces never designed for HVAC. After thirty years of East La Mirada heat, that ductwork is brittle, undersized, and frequently sagging. We replace it with properly sized, insulated hard pipe or high-grade flex where access allows.
- Refrigerant leaks at flare connections from vibration. Santa Ana wind events create pressure swings and vibration stress on outdoor units, especially older installations. We see refrigerant leaks at flare nuts and service valves more frequently here than in calmer coastal zones, and we address them with proper torque, vibration isolation, and leak testing.
- Electrical panels maxed out by modern AC loads. A 1960s ranch with original 100-amp service often can’t support a new variable-speed system without an upgrade. We assess your panel capacity during every install quote and coordinate with licensed electricians when needed, so you’re not surprised mid-project.
- Thermostat location causing short-cycling. Many East La Mirada homes have thermostats mounted on interior walls near the original wall furnace, far from where cooled air actually circulates. We relocate or upgrade to smart zoning controls that read real conditions in your living spaces.
