Roughly 60% of Van Nuys’ single-family residential stock dates between 1948 and 1968. Most of it was built as 1,200–1,800 sq ft three-bedroom tract bungalows on 6,500 sq ft lots, with original galvanized ductwork in vented attics, Sears or Wesix wall furnaces as primary heat, and either no AC at all or a window unit added in the 1970s. Layered on top of that: postwar fourplexes off Sepulveda, mid-century courtyard apartments along the Orange Line corridor, and the Vanowen and Magnolia condo conversions of the late 1990s. The Van Nuys Airport corridor and Burbank Boulevard light-industrial belt anchor a few hundred small commercial buildings (auto shops, machine shops, small offices, light manufacturing) on roof-mounted packaged HVAC.
That’s the housing stock, and it dictates almost everything about HVAC work here. The conversation isn’t about premium-tier variable-speed inverter equipment in 8,000 sq ft estates. It’s about whether the 22-year-old condenser in the side yard of a 1958 ranch is worth keeping running another two summers, whether a fourplex landlord is going to approve a $4,800 repair on a system serving four tenants, and whether a 1955 courtyard apartment with no central air is better served by mini-split or by replacing a wall unit with a newer wall unit.
Postwar tract housing: what we actually find
A typical 1958 Van Nuys ranch we open up presents the same way most days: an outdoor condenser somewhere between 12 and 28 years old (rarely original; most have been replaced once), an undersized return path that bottlenecks airflow regardless of equipment capacity, and original 1958 ductwork now mostly disconnected at branch joints from 65 years of attic heat cycles. Title 24 wasn’t a thing when the home was built; insulation is R-11 in the attic if it’s anywhere; the gas furnace in the hall closet is sometimes the original 80% AFUE unit that should have been retired in 1995.
The work usually splits into two paths. Path one: the equipment is sound and the ducts are the bottleneck, we pressure-test, identify the leakage, and seal or replace the failing sections for $1,500–$4,200 depending on accessibility. The system performs like a new install without buying new equipment. Path two: the equipment is past saving and the ducts have to come out anyway, full replacement runs $7,500–$11,500 for a 14–16 SEER2 system installed with permits and HERS verification. We measure leakage on every replacement quote so the number is on paper before you decide.
Multi-family stock: fourplexes, courtyards, condos
Van Nuys has one of the densest concentrations of small multi-family housing in the Valley. The fourplexes that line side streets off Sepulveda and Saticoy were built largely 1962–1974, typically with one outdoor condenser per unit on a shared utility-row pad and four separate air handlers in interior closets. The courtyard apartments closer to the Orange Line corridor are older, 1948–1958, and were generally built with no central air at all, wall units were added piecemeal across decades.
Multi-family HVAC is its own discipline. Shared electrical capacity that may not support new outdoor equipment without a panel upgrade. Common-area access protocols. HOA approval timelines for individual unit work. Tenant coordination on service scheduling. We do all of it. Property managers can call for portfolio service contracts; individual unit owners can call directly; renters can call for written diagnostic reports to submit to landlords. Tell us the building type when you book.
Renters: what to do when your AC dies
If you rent in Van Nuys and your AC fails, the first useful step is a written diagnostic report from a licensed contractor. We provide one on every rental-unit call: model and serial number of the failed equipment, the specific failure mode, the parts needed, the labor required, the total cost. You hand that document to your landlord or property manager and the conversation about who pays becomes much easier. We don’t take sides in landlord-tenant disputes; we document what’s broken and what the honest fix costs. The diagnostic call itself is $79, sometimes the landlord reimburses, sometimes it falls on the renter, depending on lease language.
Where mini-split is actually the right answer
Most of the 1948–1958 small apartment and courtyard buildings around the Orange Line and the older bungalows north of Victory Boulevard were never built for ductwork. Forcing it in means soffit drops, ceiling chases, and torn-up plaster that doesn’t belong in an L-shaped 950 sq ft unit. A 2-zone Mitsubishi M-Series or Daikin Fit installs in about a day with two 3-inch wall penetrations, runs at 38–45 dB indoors (the volume of a quiet conversation), and qualifies for TECH Clean California rebates of $1,500–$3,000 when configured as a heat pump. Typical 2-zone install: $4,800–$7,500. See our Mini-Split page for equipment options and project costs.
Light commercial along Van Nuys Airport and Burbank Blvd
The airport corridor and surrounding light-industrial zone host hundreds of small businesses, mostly in 1960s–80s steel-frame, flat-roof buildings on packaged rooftop units. Three failure modes drive most of our calls there: condenser fan motor burnouts in late summer, refrigerant leaks at flare fittings exposed to roof temperatures past 150°F, and electrical-side failures from contactors that never get cleaned. Service contracts on portfolios of 3+ buildings get priced at a meaningful discount over per-call rates.
Honest pricing without franchise overhead
National HVAC brands often quote 30–60% more than independent contractors for identical work, and almost all of that delta is overhead — corporate franchise fees, TV advertising budgets, commissioned-salesperson incentives. We don’t carry any of that. Diagnostic fee $79 (waived if we proceed). Common Van Nuys repairs: capacitor $180–$320, contactor $200–$360, condenser fan motor $420–$720, R-410A recharge $320–$640, full system replacement $7,500–$11,500. Every line itemized; if you want to compare against a national-brand quote, you’ll be able to do it part by part.
