Fast, Reliable AC Repair & Installation Across Westlake Village
AC repair in Westlake Village typically runs $150–$650, and most repairs are completed same day. Installation of a new system for the area’s larger homes generally falls between $3,500–$7,500 depending on tonnage, duct condition, and whether zoning is added. Call (844) 560-6978 for a free estimate.
We’ve been serving Westlake Village homeowners for nearly two decades, and we know the Conejo Valley’s specific demands. Summer temperatures here push 95–105°F during Santa Ana events, while winter nights dip to the mid-30s. That dual-season load means your system works harder than equipment in coastal LA neighborhoods where cooling barely runs. We’re familiar with the master-planned neighborhoods off Agoura Road, the Westlake Lake area, and the Foxfield tract — and we understand how the original 1968–1995 construction cycles affect what we’re likely to find in your attic.
Why Crestview Heating & Air California Is Westlake Village’s Preferred AC Repair & Installation Company
Our AC Repair & Installation team has built a 4.8-star average across 250+ customer reviews, and many of those come from repeat calls in the 91359 and 91361 ZIP codes. Westlake Village residents aren’t looking for a dispatcher in another county. They’re looking for Marcus Feldman, our Owner and Service Manager, who still manages jobs in the field personally.
That ownership-level accountability matters when you’re dealing with a 1980s air handler platform that’s leaking condensate into a ceiling, or a seized compressor during a September heat event. We’ve replaced systems on Lindero Canyon Road, repaired ductwork in the original lakeside tracts, and diagnosed refrigerant leaks in homes off Triunfo Canyon. The response time to Westlake Village from our operation is straightforward — we’re not routing trucks from downtown LA or the Valley.
Nearly two decades of HVAC experience means we’ve worked on virtually every system age and configuration found in Westlake Village’s uniform housing stock. Your system, our specialty — whether it’s a 35-year-old Carrier still limping along or a newer Rheem that needs zoning optimization.
Our AC Repair & Installation Services in Westlake Village
AC Repair
Most Westlake Village AC repair calls we handle involve capacitor failure, compressor electrical issues, or refrigerant leaks in aging condensing units. The Santa Ana wind episodes in late summer and fall are a concentrated stress period — outdoor coils clog with dust, and head pressures spike on systems already running at capacity. A typical repair in Westlake Village runs $150–$650. We stock capacitors, contactors, and refrigerant for same-day resolution on most calls.
AC Installation
Westlake Village’s master-planned development means most homes were built with original AC systems simultaneously around 1968–1995, creating a synchronized replacement wave as R-4/R-6 flex ducts and aging air handlers now fail citywide. The predominantly affluent homeowner base here expects premium zoned systems and high-SEER equipment, not entry-level swaps. Our installations range from $3,500–$7,500, with most larger homes in the 2,500–5,000 sq ft range landing in the upper half of that band once zoning and duct upgrades are factored.
AC Replacement
Replacement in Westlake Village isn’t just swapping boxes. The original air-handler platforms from the 1970s–90s often lack proper drainage geometry for modern high-SEER coils, leading to condensate overflow. We rebuild platforms, upsize drain lines, and verify pitch. Uniform roof tile age across neighborhoods also means compressor access frequently requires tile removal or lift rental — we plan for this, not discover it mid-job.
Refrigerant Recharge
Low refrigerant in Westlake Village usually signals a leak, not normal consumption. We locate and repair the source before recharging — whether it’s a corroded evaporator coil, a leaking flare fitting, or pinholes in line sets running through 140°F attic spaces. A recharge with leak repair typically falls in the $150–$650 repair range depending on refrigerant type and accessibility.

Common AC Repair & Installation Problems We See in Westlake Village Homes
- Flex duct delamination in attic heat. In the original 1970s lakeside tracts, flex duct runs through attics where temps exceed 140°F under tile roofs. The R-4 or R-6 insulation separates from the inner liner, collapsing airflow. Homeowners feel weak supply at registers while the system runs constantly. We find this almost every time we inspect attics in the older Westlake Lake-adjacent streets.
- Condensate overflow from outdated platforms. Original air-handler platforms weren’t designed for the steeper coils on high-SEER replacement equipment. The drain pan geometry is wrong, the line is undersized, and water ends up in ceilings. We see this repeatedly in homes built 1975–1985.
- Compressor failure during Santa Ana events. September through November brings low-humidity, high-temperature stress that pushes aging condensing units past their limits. The Conejo Valley’s inland position makes these episodes more severe than coastal areas. Failed compressors in 25+ year old systems usually mean replacement, not repair.
- Tile roof access complications. Westlake Village’s clay and concrete tile roofs are uniform across neighborhoods, and they’re brittle after decades. Compressor replacement or condenser cleaning often requires protective walkboards, tile lift rentals, or selective removal. We quote this upfront, not as a surprise.
Pricing for AC Repair & Installation in Westlake Village, CA
We’re straightforward about numbers because Westlake Village homeowners are shopping with real budgets. Here’s what our AC Repair & Installation work typically costs:
| Service | Price Range in Westlake Village |
|---|---|
| AC Repair (including refrigerant, electrical, minor parts) | $150–$650 |
| AC Installation (new system, standard home) | $3,500–$7,500 |
| AC Tune-Up & Inspection | $80–$200 |
What moves you within these ranges? System tonnage, duct condition, whether zoning is added, and roof access difficulty. A 3,200 sq ft home with failing R-6 flex duct and a tile roof needing lift access will land higher than a straightforward ground-level swap on a smaller home with good ductwork. We inspect, measure, and quote before any work begins — estimates are free. Call (844) 560-6978 to schedule.

FAQs — AC Repair & Installation in Westlake Village
At 50 years, replacement is almost always the better investment. Original equipment from that era runs at 6–8 SEER versus 16–20 SEER for modern systems, and the original R-4 flex duct in your attic has likely delaminated. We can repair a failed compressor or capacitor to get you through a heat event, but we’d recommend budgeting for full replacement within the next 1–2 seasons. Call (844) 560-6978 and we’ll inspect your ductwork and platform condition to give you a straight answer.
Yes, significantly. The Santa Ana winds in September through November bring low-humidity, 95–105°F conditions that force your condenser to work at maximum capacity while dust clogs the outdoor coil. Aging systems often fail during these episodes because they’re already running near limit. We recommend pre-season tune-ups in August to clean coils and check refrigerant charge before the stress hits.
Very common, especially in the 2,500–5,000 sq ft homes that dominate here. Master-planned homes were built with single-zone systems that struggle to balance temperatures across large footprints. We regularly install zoned dampers with new Trane or Lennox systems, particularly in two-story homes where upstairs cooling lag is the primary complaint. Zoning adds roughly $800–$1,500 to a standard replacement but solves comfort complaints that new equipment alone won’t fix.
We typically recommend 16–18 SEER for Westlake Village’s climate and utility rates. The tile roof creates extreme attic heat, so higher SEER equipment with variable-speed blowers pays back faster here than in milder coastal zones. California’s Title 24 requirements also set minimums. We size carefully — oversizing is a common mistake in large homes that leads to short-cycling and humidity control problems.
It’s almost certainly the ducts. Original R-6 flex in 140°F attic conditions loses insulation adhesion, collapses at bends, and develops leaks at connections. The AC unit may be producing full capacity, but that capacity never reaches your upstairs registers. We see this constantly in Westlake Village’s 1980s tracts. A duct inspection with airflow measurement will tell the story — and duct replacement or upsizing to R-8 often delivers more comfort improvement than a new condenser alone.
In the Foxfield tract near Westlake Lake, we replaced a 1988 Carrier condensing unit that had seized during a Santa Ana event. The original R-6 flex duct in the attic had delaminated under 140°F tile-roof temps, so we upsized to R-8 and installed a high-SEER Trane system with zoned dampers for the owner’s 3,200 sq ft home.
