Fast, Reliable AC Repair & Installation Across Canoga Park
AC repair in Canoga Park typically costs $150–$650, and most jobs are diagnosed same-day. Installation of a new system runs $3,500–$7,500 depending on size, duct condition, and whether your home needs electrical upgrades. If your compressor’s running but you’re still sweating, the problem is often failed ductwork in your attic, not the unit itself.
We’re Stonegate Heating & Air California, and our AC Repair & Installation team has been handling the western San Fernando Valley’s brutal heat for 16 years. Owner Jason Trent supervises every project in the field, not from a desk. We know Canoga Park’s 91303, 91304, 91305, and 91309 ZIP codes well, from the dense tract neighborhoods along Vanowen Street to the ranch homes tucked below the Santa Susana Mountains. Summer temperatures here hit 105–110°F while Santa Monica stays at 75°F. That 25–35°F gap isn’t a trivia fact; it’s why your AC fails differently than a coastal system’s.

Why Stonegate Heating & Air California Is Canoga Park’s Preferred AC Repair & Installation Company
We’ve earned 499 verified reviews averaging 4.7 stars across platforms, and a solid share of those come from Canoga Park homeowners who found us after bad experiences with dispatch-only operations. Jason Trent holds the title of Field Supervisor, meaning he’s physically on job sites from initial diagnosis to final testing. In Canoga Park, where attic work at 150°F separates real technicians from phone jockeys, that matters.
Our response time to Canoga Park is built around the reality of this market: heat emergencies here are genuine emergencies, not discomfort. When a Santa Ana wind event drops humidity to single digits and your system is already running near capacity from three months of 100°F+ days, a next-week appointment isn’t useful. We prioritize same-day diagnosis for Canoga Park calls because we’ve seen what this climate does to equipment.
Our 16 years in California HVAC means we’ve watched Canoga Park’s housing stock age in real time. We know which 1960s Lennox units are still clinging to life in the tract homes near Sherman Way, which Goodman systems were installed in the 1980s rebuilds, and how the original ductwork in those post-war ranches was never designed for the heat extremes of the 2020s. That institutional memory saves diagnostic time and prevents misdiagnosis.
Our AC Repair & Installation Services in Canoga Park
AC Repair
Most Canoga Park repair calls we see aren’t compressor failures. They’re duct collapses, frozen coils from undersized equipment running 18 hours straight, or condensate drains clogged with attic debris. Our repair pricing runs $150–$650, and we start with a full system test, not a guess. We work on nine major brands, so we don’t hit you with “we don’t service that” after you’ve already waited.
AC Installation
New AC installation in Canoga Park runs $3,500–$7,500. The wide range reflects a reality specific to this area: many 1950s–1970s ranch homes need electrical panel upgrades to handle modern equipment, and nearly all need ductwork replacement before a new unit will perform to spec. We size every installation to current Manual J standards using actual Canoga Park design temperatures, not coastal LA numbers. A system sized for Santa Monica will fail here.
AC Replacement
Replacement in Canoga Park often means more than swapping boxes. The original equipment in these tract homes was frequently undersized even by 1960s standards, and decades of 150°F+ attic exposure have destroyed what little insulation the ductwork once had. We replace the full system, including ducts, when that’s what the house needs. Jason Trent supervises every replacement personally.
Refrigerant Recharge
Low refrigerant in Canoga Park usually signals a leak, not normal consumption. The thermal cycling here, extreme even by Valley standards, stresses line sets and coil joints. We locate and repair leaks before recharging; adding refrigerant to a leaking system is throwing money into your attic. Recharge costs fall within our standard $150–$650 repair range.
Duct Inspection & Repair
This is where our Canoga Park expertise pays off most. We worked a job on Vanowen Street where a 1960s ranch home’s duct board had shattered in the attic, dumping all cooled air into the crawlspace; the compressor tested perfect, but the owner was sweating at 95°F indoors. We replaced the ductwork with modern, insulated flex ducts and upgraded their aging Lennox unit to a variable-speed system, cutting their summer bills by 25%. In Canoga Park, duct inspection is our first stop, not our last.

Trusted Brands We Service in Canoga Park
We’re certified and experienced on nine leading HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Canoga Park customers, this means no dead ends. We’ve got parts relationships and technical documentation for all nine, so when your Trane’s variable-speed blower fails in August or your Lennox coil freezes in a Santa Ana event, we’re not ordering manuals and guessing. We stock common capacitors, contactors, and refrigerant types locally to cut downtime. Whatever brand you have, one team handles it.
Common AC Repair & Installation Problems We See in Canoga Park Homes
- Duct collapse in scorching attics. Original foil-backed fiberglass duct board from the 1960s and 1970s degrades after decades of 150°F+ exposure. The dense tract neighborhoods along Vanowen and Sherman Way produce a predictable late-summer failure pattern: shattered duct board dumping cooled air into attics and crawlspaces while the compressor runs fine.
- Undersized equipment from original builds. 1960s Manual J calculations didn’t account for 105°F+ summer peaks. Systems sized for those specs run continuously, freeze coils, and fail prematurely. We see this constantly in Canoga Park’s single-story ranches.
- Condensate drain clogs from attic debris. Tight tract neighborhoods generate dust and debris that collect in attic condensate lines. When these clog, water backs up and damages drywall and ceilings, a secondary repair that could’ve been prevented with routine maintenance.
- Electrical panels overwhelmed by modern loads. Many Canoga Park homes still run original 100-amp panels. A new variable-speed system or heat pump upgrade often requires panel work before installation can proceed, adding scope that coastal contractors don’t anticipate.

FAQs — AC Repair & Installation in Canoga Park
Your ductwork has likely failed in the attic. In Canoga Park’s 150°F+ attics, original 1960s duct board and foil-backed fiberglass deteriorate and collapse after decades, dumping cooled air into the crawlspace or attic while the compressor runs perfectly. We inspect ducts first on every “warm air” call in Canoga Park. Call (855) 467-1888 and we’ll diagnose it same-day.
Yes, the City of Los Angeles requires permits for AC replacement in Canoga Park, which falls under LADBS jurisdiction. We handle permit filing as part of our installation service; you don’t need to visit the Van Nuys office yourself. This is standard on our jobs, not an upsell. Call (855) 467-1888 for details on your specific project.
Santa Ana winds drop humidity to single digits and spike temperatures in fall, when your system has already run near capacity all summer. This combination stresses compressors, dries seals, and can trigger failures in equipment that was marginal in July. We see a secondary surge of emergency calls in October and November, distinct from coastal patterns. Call (855) 467-1888 if your system’s struggling in a Santa Ana event.
In Canoga Park, almost always yes. Original ductwork in these tract homes was never designed for current heat loads, and decades of 150°F+ attic exposure have destroyed insulation and structural integrity. Installing a new, properly sized unit on failed ducts wastes capacity and money. We include duct inspection in every installation quote and won’t install on ducts we know will fail. Call (855) 467-1888 for a full-system assessment.
We size to current Manual J standards using Canoga Park’s actual design temperatures, not coastal LA numbers. “Oversized” is the wrong goal; properly sized is what matters. Many original Canoga Park systems are actually undersized by modern standards, and simply swapping like-for-like leaves you with a unit that can’t handle 110°F days. We calculate precise load based on your home’s square footage, insulation, window efficiency, and duct condition. Call (855) 467-1888 for a proper load calculation.
