We’re Crestview Heating & Air California, and we know Sherman Oaks. We know the flatlands south of Ventura Boulevard where 1960s ranch homes bake in 100°F-plus heat, and the hillside streets above where older systems strain against afternoon sun exposure. We’ve been called to homes on Dickens Street, near the Galleria, and up toward Mulholland Drive. Sherman Oaks isn’t a generic service area for us. It’s a specific climate challenge: the Santa Monica Mountains block the marine layer, so your AC runs harder and longer than systems just five miles south in Brentwood. That’s why local experience matters here.
Our AC Repair & Installation team responds to Sherman Oaks calls with trucks stocked for the brands and problems we see most in this market. Owner Marcus Feldman still manages jobs in the field, so the person quoting your repair is the same person accountable for the fix.
Why Crestview Heating & Air California Is Sherman Oaks’s Preferred AC Repair & Installation Company
Nearly two decades of HVAC experience means we’ve worked on virtually every system type found in Sherman Oaks’s post-WWII housing stock. The 1950s–1970s ranch homes that define this neighborhood carry specific problems: original ductwork in unconditioned attics, earthquake damage from 1994 that was never properly addressed, and compressors that weren’t designed for modern Valley heat loads. We’ve seen these patterns enough to diagnose them fast.
Our 4.8-star average rating across 250+ customer reviews reflects consistent real-world performance. Sherman Oaks homeowners specifically mention our willingness to investigate attic ductwork when other companies only checked the thermostat and condenser. That’s owner-managed accountability, not outsourced dispatch.
We don’t quote from a script. Marcus Feldman serves as both Owner and Service Manager, which means ownership-level accountability is built into daily operations. When we recommend a repair versus a full replacement, it’s based on what we’ve measured in your attic, not a sales quota.
From emergency calls to commercial buildouts, we serve a broader range than most local HVAC shops. But Sherman Oaks residential work remains our core. Your system, our specialty.
Our AC Repair & Installation Services in Sherman Oaks
AC Repair
Sherman Oaks summers push AC systems to their breaking point. We repair compressors, capacitors, contactors, and refrigerant lines across the 91403, 91413, 91423, and 91495 ZIP codes. The most common call we get: the system runs but can’t keep up. Often the culprit isn’t the condenser at all. It’s earthquake-displaced ductwork leaking 25–35% of cooled air into a 150°F attic. We find and fix that.
AC Installation
New AC installation in Sherman Oaks requires sizing for real Valley conditions, not textbook coastal calculations. A system rated for Los Angeles often falls short here where temperatures hit 110°F and attics reach 150°F+. We size for load, seal ductwork before connecting new equipment, and verify airflow at every vent. Installation costs range $4,130–$8,850 depending on tonnage, ductwork condition, and whether we need to replace refrigerant lines.
AC Replacement
When to replace versus repair? For Sherman Oaks homeowners with original 1960s–70s units, the math usually tips toward replacement once repair estimates exceed $600–$700 and the system uses R-22 refrigerant. New 16+ SEER systems cut operating costs significantly in high-run-time markets like ours. We handle full removal, permitting, and disposal.
Refrigerant Recharge
Low refrigerant in Sherman Oaks often signals a leak, not just normal depletion. Extended compressor run times in Valley heat stress refrigerant lines and flare fittings. We locate leaks with electronic detection and nitrogen pressure testing, then recharge to manufacturer spec. A proper fix, not a temporary top-off that fails by August.
Ductwork Repair
This is where our Sherman Oaks expertise pays off most. We arrived at a 1960s ranch home on Dickens Street in the flatlands south of Ventura Blvd to find the AC blowing warm air. The compressor was laboring, and when we opened the attic we found a flex-duct collar that had been torn loose in the 1994 Northridge earthquake and never resealed — the homeowner had been losing over 30% of cooled air into a 150°F attic for 30 years. We reconnected and mastic-sealed the joint, recharged the refrigerant, and the system delivered a 20°F temperature drop at the vents. Ductwork repair isn’t glamorous. It’s often the difference between a system that works and one that never will.

Trusted Brands We Service in Sherman Oaks
Your system, our specialty. We service and stock parts for Trane, Lennox, Goodman, Rheem, and five additional major brands. Sherman Oaks homeowners with older Goodman or Rheem units — common in 1970s tract builds — often assume parts are obsolete. They’re not. We carry capacitors, contactors, and compressor hardware for these legacy systems, which means faster turnaround and no waiting for Valley distributors to open Monday morning. Factory-trained compatibility across nine brands means we never tell you “we don’t work on that.”
Common AC Repair & Installation Problems We See in Sherman Oaks Homes
- Hidden earthquake-displaced duct joints from the 1994 Northridge quake leak conditioned air directly into scorching attics, wasting 25–35% of cooling capacity. Structural contractors patched drywall after the quake, but HVAC permits weren’t pulled and flex-duct collars were never resealed. We find this in roughly one of every three 1960s–70s ranch homes we inspect.
- Original 1960s–70s ductwork wrapped in asbestos tape or low-R-value insulation deteriorates in 150°F+ attic heat, causing total system failure mid-August. The insulation crumbles. The tape delaminates. Suddenly your 5-ton system is delivering 3 tons of cooling to the rooms below. We replace with R-8 flex duct or hard pipe where appropriate.
- Legacy one-speed compressor units on 50–60 year old slabs are undersized and prone to refrigerant line corrosion from extended run-times in the Valley’s 100–110°F summers. These systems weren’t designed for modern heat loads. They run constantly, never cycle off, and burn through capacitors annually. Variable-speed replacement typically cuts runtime hours by 30–40%.
- Capacitor failure accelerated by attic heat and extended compressor cycling. A capacitor that lasts 8–10 years in Santa Monica often fails in 3–4 years in Sherman Oaks. We upgrade to higher-temp-rated components where the application allows.

FAQs — AC Repair & Installation in Sherman Oaks
We can usually keep a 1960s unit running with capacitor replacement, contactor service, or refrigerant recharge, but replacement becomes the smarter investment once repair estimates approach $600–$700 or the system uses R-22 refrigerant. Original units in Sherman Oaks are typically 6–8 SEER; modern systems start at 14 SEER and cut cooling costs by 40–50% in high-run-time Valley conditions. Call (844) 560-6978 for a free evaluation of your specific unit.
This pattern almost always indicates ductwork problems, not a failing compressor. In Sherman Oaks ranch homes, we regularly find earthquake-displaced duct boots, torn flex-duct collars from the 1994 Northridge quake, or deteriorated insulation that lets 150°F attic air warm your supply air before it reaches the back of the house. We inspect attic ductwork with every service call and can typically identify the problem within 30 minutes. Call (844) 560-6978 to schedule ductwork diagnostics.
Full ductwork replacement in a typical 1,200–1,800 square foot Sherman Oaks ranch home runs $2,800–$5,500 depending on attic accessibility, number of vents, and whether we need to reroute around structural modifications. Partial repairs — resealing joints, replacing damaged flex runs — typically fall in the $800–$1,800 range. The investment usually pays back in 2–3 summers through reduced runtime and lower energy bills. Call (844) 560-6978 for an exact quote based on your attic layout.
Yes. Original asbestos duct tape or later fiberglass tape deteriorates in 150°F+ Sherman Oaks attics, and kitchen vents are often the longest runs with the most joints. We find failed tape allowing supply air to leak into the attic before reaching the register. Mastic sealing or duct replacement solves this permanently. We see this exact scenario in homes throughout the flatlands south of Ventura Boulevard. Call (844) 560-6978 and we’ll trace the kitchen duct run.
It is. Capacitors in Sherman Oaks fail faster than in coastal LA because extended compressor run times in 100–110°F heat cause more electrical cycling stress, and attic-mounted air handlers expose components to ambient temperatures 20–30°F higher than design spec. A capacitor rated for 10 years in milder climates often lasts 3–4 years here. We install higher-temp-rated replacements and can relocate controls to cooler locations where practical. Call (844) 560-6978 if you’re on your third capacitor in five years.
