We’ve been working the 91343 and 91393 ZIP codes long enough to know that North Hills isn’t like the rest of Los Angeles. The San Fernando Valley traps heat here, and those 1950s–1970s slab-on-grade tract homes off Nordhoff Street and Remmet Avenue face HVAC challenges that coastal contractors rarely encounter. Gregory Hahn founded this company and still leads every technical decision, bringing 13 years of master-technician experience to jobs that demand more than a rushed diagnosis.
Why Redwood Heating & Air San Diego Is North Hills’s Preferred Heat Pump & Mini Split Company
North Hills homeowners call us because we’ve earned 428 verified reviews averaging 4.6 stars, built over 13 continuous years of operation. That volume matters in a neighborhood where word travels fast through the community Facebook groups and Nextdoor threads.
Our response time to North Hills averages under an hour because we know the local street grid and traffic patterns around the 118 Freeway corridor. We’ve replaced compressors on July afternoons when the asphalt on Sepulveda Boulevard was softening, and we’ve diagnosed failing capacitors in January Santa Ana wind events that push attic temperatures past 120°F even in winter.
Gregory Hahn holds a Master Technician designation, and that credential rides in the truck to every North Hills job. Customers get owner-level accountability, not a franchise dispatcher sending whichever crew is available. We service your brand, whether it’s a 30-year-old Goodman that survived the 1994 earthquake or a new Daikin mini-split you want zoned for a converted garage.
From a single mini-split to a full commercial system, we bring the same diagnostic rigor. Diagnosed right the first time isn’t a slogan here. It’s how we’ve stayed in business while dozens of one-truck operations came and went.
Our Heat Pump & Mini Split Services in North Hills
Heat Pump Repair
North Hills heat pumps work harder than almost any in the metro. Triple-digit heat waves from late June through September burn out capacitors and compressors at rates that make annual maintenance essential, not optional. We recently serviced a 1964 tract home on Remmet Avenue where the original 1995 post-earthquake heat pump had a seized compressor and the attic ductwork tested at 38% leakage. We explained that a central replacement would still lose a third of its capacity through the ducts, so the homeowner chose a two-zone Daikin mini-split system with wall-mounted air handlers, which cut their August cooling bill by nearly half and eliminated the duct-loss penalty entirely.
Common failures we see in 91343 and 91393: seized compressors on 28–30-year-old post-quake units, brittle wiring from attic heat cycling, and refrigerant leaks at flare connections that failed after decades of vibration. Most repairs run $150–$650 depending on parts and refrigerant charge.
Heat Pump Installation
New heat pump installation in North Hills demands honest load calculation. Many contractors size replacement units based on the existing equipment, but that original equipment was fighting 30–40% duct leakage from day one. A proper Manual J calculation for a North Hills home often reveals that the house needs less tonnage than the old label suggests, because the new unit won’t be bleeding conditioned air into a 140°F attic.
That said, slab-on-grade construction with no basement or crawl space complicates line-set routing for central systems. We walk homeowners through the real trade-offs: a central heat pump with new ductwork, or bypassing the ducts entirely. Installation ranges from $3,500–$7,500 depending on tonnage, electrical upgrades, and whether we’re retrofitting or starting fresh.
Mini Split Install
In North Hills, mini-split systems are increasingly favored over central ducted heat pumps because the neighborhood’s 1950s–1970s slab-on-grade tract homes often lack attic space for air handlers, and the existing ductwork — baked brittle by 140°F+ attic summers — typically leaks 30–40%, making a ductless retrofit more efficient and cost-effective. We install single-zone systems for garage conversions and home offices, and multi-zone systems that let a family cool the living room during the day and bedrooms at night without conditioning empty spaces.
Multi-zone systems are particularly popular in the larger 1960s ranch homes near North Hills Park, where parents want master suite control separate from kids’ rooms. Wall-mounted, floor-mounted, and ceiling cassette options let us work around the low-pitch roofs and limited wall space common in postwar construction.
Mini Split Repair
Ductless systems fail differently than central equipment. We see clogged condensate drains from North Hills’s dust and Santa Ana ash, failed inverter boards from voltage spikes during summer grid strain, and refrigerant leaks at the outdoor unit flare nuts that work loose after years of thermal cycling. Most mini-split repairs run $150–$650, same as conventional AC repair, though inverter board replacements can push toward the higher end.
Because we stock parts for Carrier, Trane, Bryant, and American Standard, plus universal mini-split components, most North Hills repairs finish in one visit. No waiting a week for a distributor shipment while your house hits 95°F inside.

Trusted Brands We Service in North Hills
We service your brand. Gregory Hahn built this company on factory-trained experience across nine major HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For North Hills customers, that means we don’t try to sell you what we happen to stock. We diagnose the actual failure and source the correct part, whether it’s a Carrier Infinity compressor, a Trane XV20i inverter, or a Daikin Emura mini-split head.
Our trucks carry the most common capacitors, contactors, and refrigerants for these brands, plus universal mini-split flare kits and drain pumps. Most North Hills jobs don’t require a parts run. When something unusual is needed, our San Diego supply-house relationships get it next-day, not next-week.
Common Heat Pump & Mini Split Problems We See in North Hills Homes
- Brittle attic ductwork bleeding 30–40% of conditioned air. Technicians working North Hills regularly find attic ductwork that has become brittle and unsealed after decades of 140°F+ attic summers. A duct system that tests at 30–40% leakage is normal here, meaning an oversized or undersized unit installed at the original build is still fighting both a Manual J mismatch and massive duct losses simultaneously, something a tech in a coastal Westside neighborhood almost never encounters.
- Post-1994 earthquake replacements hitting end of life. The 1994 Northridge earthquake forced emergency HVAC replacements across North Hills in 1994–1996. That 28–30-year-old equipment cohort is now failing all at once, creating a concentrated replacement cycle unlike any neighboring community. Capacitor swelling, compressor hard starts, and refrigerant leaks are epidemic in these units.
- Sustained triple-digit loads with no overnight recovery. North Hills sits deep inside the San Fernando Valley’s inland basin, where surrounding mountain ranges trap heat and produce summer highs that routinely run 15–20°F above coastal LA neighborhoods just 20 miles away. Overnight lows often stay above 75°F during heat events, preventing the system recovery a coastal unit would get. This sustained heat load burns out capacitors, fan motors, and compressors at rates that make annual preventive maintenance essentially mandatory rather than optional.
- Slab-on-grade electrical panels too small for modern heat pumps. Many 1950s–1970s North Hills homes still have 100-amp panels that can’t handle the inrush current of a modern variable-speed heat pump, let alone a multi-zone mini-split with multiple outdoor compressors. We identify this during our free estimate and coordinate licensed electrical upgrades when needed.
Pricing for Heat Pump & Mini Split in North Hills, CA
We’re straightforward about numbers because North Hills homeowners research before they call. Here’s what we typically see in the 91343 and 91393 ZIP codes:
| Service | Typical Range in North Hills |
|---|---|
| AC / Heat Pump Repair | $150–$650 |
| Heat Pump Installation | $3,500–$7,500 |
| Tune-Up / Preventive Maintenance | $80–$200 |
| Mini-Split Installation (single zone) | $3,500–$5,500 |
| Multi-Zone Mini-Split (2–4 zones) | $5,500–$7,500 |
What moves the needle within these ranges: electrical panel upgrades, line-set length and routing difficulty on slab homes, and whether we’re abandoning existing ductwork or working around it. The brittle ductwork common in North Hills often tips the decision toward ductless, which eliminates the $2,000–$4,000 duct replacement cost but adds indoor head units. We lay out both paths during your free estimate and let you decide. Call (844) 875-9451 to schedule.

FAQs — Heat Pump & Mini Split in North Hills
North Hills’s 1950s–1970s slab-on-grade tract homes often lack usable attic space for air handlers, and the existing ductwork has been baked brittle by 140°F+ attic summers until it leaks 30–40% of conditioned air. A ductless mini-split bypasses both problems entirely, delivering 100% of its capacity to the rooms you actually use. Call (844) 875-9451 and we’ll test your duct leakage so you can see the real numbers before deciding.
The 1994 earthquake forced emergency HVAC replacements across North Hills in 1994–1996, and that 28–30-year-old equipment cohort is now failing all at once, creating a concentrated replacement cycle unlike any neighboring community. If your unit has a 1995–1996 date stamp, you’re in the statistical peak failure window. We can inspect and give you an honest repair-versus-replace assessment at no charge.
Yes, modern inverter-driven mini-splits are engineered for exactly this. Daikin and Carrier ductless systems maintain full rated capacity at 115°F ambient, and their variable-speed compressors don’t cycle on/off like old central units, so they dehumidify better and run more efficiently during sustained heat events. We’ve installed hundreds in the San Fernando Valley, and August utility bills consistently drop versus the old central systems they replaced.
North Hills attics exceed 140°F in summer, and that extreme heat accelerates duct seal degradation while simultaneously increasing the temperature gap between conditioned air and attic air. A 30% leak in a 75°F Santa Monica attic loses some efficiency; the same 30% leak in a 140°F North Hills attic is dumping nearly half your cooling capacity into a superheated space. The penalty is geometric, not linear. That’s why we test duct leakage on every estimate and show you the actual CFM loss.
Usually not, if the repair exceeds $400 and the unit still uses R-22 refrigerant. That equipment is 28–30 years old, past design life, and replacement parts are increasingly scarce and expensive. We make exceptions for minor repairs on well-maintained units, but we won’t take your money for a compressor replacement that buys you two more years. Call (844) 875-9451 for an honest assessment — estimates are free, and we’ll tell you straight.
