We’ve been serving California for 16 years, and Van Nuys is one of the most demanding HVAC environments we work in. The San Fernando Valley floor acts as a heat sink — readings at Van Nuys Airport routinely top 100°F from June through September, with spikes above 110°F most summers. That’s 25–35°F hotter than Santa Monica on the same afternoon. Your air conditioner isn’t fighting the outside air alone. It’s fighting attic temperatures that climb past 150°F in those unconditioned spaces where most Van Nuys ductwork lives.
Our AC Repair & Installation team understands this local dynamic. Jason Trent, our owner and active Field Supervisor, has supervised jobs in the 1950s ranch homes near Victory and in the low-rise apartment buildings along Van Nuys Boulevard. We don’t send whichever tech is available that day. Jason puts experienced, accountable hands on every project.
Why Stonegate Heating & Air California Is Van Nuys’s Preferred AC Repair & Installation Company
Local reputation built on valley-floor expertise. We’ve worked on enough Van Nuys systems to know that a “simple” refrigerant recharge often signals deeper problems — corroded coils from salt air, stressed compressor seals from temperature swings, or flex duct that’s literally cooking the cooled air before it reaches your vents. Our 499 verified reviews at a 4.7-star average reflect jobs done right in conditions exactly like yours.
Owner supervision, not remote management. Jason Trent holds the title of Field Supervisor, not just Owner. That means company leadership is physically present on Van Nuys job sites, not managing from a back office. When we diagnose a system near Van Nuys Airport or along Sepulveda Boulevard, Jason reviews the findings himself.
Nine brands, one team. We’re certified to work on Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. Whatever brand your Van Nuys home has, we stock parts and we know the equipment. No “we don’t service that brand” dead ends.
Full spectrum, single provider. From a single-room mini split to a full commercial system, we handle it. That includes emergency HVAC when your system fails during a 110°F Van Nuys afternoon.
Our AC Repair & Installation Services in Van Nuys
AC Repair
Van Nuys AC repair calls spike in July and August, but the damage usually starts earlier. Winter nights in the mid-30s°F followed by summer’s aggressive heat cycle stress refrigerant seals and capacitor connections. Salt-air corrosion from coastal proximity attacks condenser coils faster than in inland Sacramento. We diagnose the real failure, not just the symptom. A typical AC repair in Van Nuys runs $150–$650, and we’ll give you an exact quote before any work begins.

AC Installation
New AC installation in Van Nuys demands more than proper sizing by square footage. The bulk of local housing stock — post-WWII stucco ranches and low-rise apartments built 1950–1975 — was originally equipped with wall heaters and window units. Central systems were retrofitted later, leaving flex duct crammed into attics that hit 150°F. We size systems to overcome those heat-gain losses, and we’ll tell you honestly when your ductwork needs replacement alongside the new unit. Installation runs $3,500–$7,500.

AC Replacement
Replacing an AC in Van Nuys often means confronting what the previous installer ignored. That 1970s flex duct in your attic? It’s not just inefficient. It’s actively working against your new equipment. We evaluate the full system — condenser, coil, ductwork, and static pressure — because replacing only the box outside while ignoring the attic conditions is how homeowners end up with a new unit that still “can’t keep up.” We’ve seen it near Van Nuys Boulevard. We won’t let it happen on our jobs.

Refrigerant Recharge
Low refrigerant in Van Nuys usually means a leak, not normal consumption. The annual temperature swing from 35°F winter nights to 110°F summer days stresses compressor seals and flare connections. Salt air accelerates corrosion at the condenser. We locate the leak, repair it, and recharge to factory spec — not just top off and hope. If your system needs R-22 and you’re facing replacement, we’ll give you straight numbers on repair versus upgrade.

Common AC Repair & Installation Problems We See in Van Nuys Homes
- Original flex duct retrofits bleeding cooled air into 150°F attics. The 1950s–70s housing stock dominates Van Nuys, and most central AC was added after construction. That flex duct was never meant for unconditioned attic runs. We regularly find systems losing 30%+ of cooling capacity before air reaches the vent.
- Salt-air corrosion attacking condenser coils and refrigerant seals. Van Nuys sits closer to coastal influence than inland valleys. Condenser fins deteriorate faster, seals weaken, and leaks develop at connection points that would last years longer in drier climates.
- Capacitor and compressor failure from extreme temperature cycling. The swing from mid-30s winter nights to 110°F summer afternoons puts exceptional wear on starting components. We replace capacitors with higher-temp-rated units suited to Van Nuys conditions.
- Static pressure problems from ductwork never engineered for central HVAC. Retrofitted soffits and cramped attic spaces create airflow restrictions. New equipment gets blamed for poor performance when the real issue is duct design from decades ago.

FAQs — AC Repair & Installation in Van Nuys
The most common cause is original 1970s flex duct running through an attic that exceeds 150°F. That ductwork was retrofitted into homes never designed for central air, and it bleeds cooled air before it reaches your living space. In the 1950s ranch homes near Van Nuys Boulevard and Victory Boulevard, we replaced a Lennox condenser that was failing to cool below 85°F; the real culprit was the original flex duct in a 150°F attic, which we replaced with insulated metal duct to restore proper airflow and cooling. If your new unit “can’t keep up,” call (855) 467-1888 for a duct evaluation.
Most systems last 12–15 years in Van Nuys’s demanding climate, though we’ve seen well-maintained units fail at 10 and others run to 18. The extreme temperature swing and near-continuous summer load accelerate wear. Salt-air corrosion also shortens condenser life compared to inland locations. If your system is 12+ years old and repair costs exceed 40% of replacement, we recommend getting quotes. Call (855) 467-1888 for a free assessment.
You need proper ductwork, not a special AC model. The equipment itself — whether Carrier, Trane, or Lennox — performs fine in Van Nuys when paired with insulated metal duct or properly sealed flex in conditioned space. We evaluate attic conditions on every installation and specify duct replacement when needed. A new condenser with failing ductwork is wasted money. Call (855) 467-1888 to discuss your attic situation.
Three factors dominate: salt-air corrosion at the condenser, thermal cycling stress on seals from 35°F to 110°F annual swings, and vibration at poorly supported line sets in retrofit installations. We pressure-test the entire system, repair the leak at its source, and recharge to factory specification. Topping off without repair is temporary and illegal under EPA regulations. Call (855) 467-1888 if your system needs refrigerant.
Sometimes, but honestly less often than owners hope. R-22 refrigerant is no longer manufactured, so repairs requiring refrigerant work get expensive fast. More critically, 1970s systems were paired with ductwork never engineered for modern efficiency standards. We’ve repaired units that ran another season, and we’ve advised replacement when the math didn’t work. We’ll give you both numbers straight. Call (855) 467-1888 for an honest evaluation.
