We’re Crestview Heating & Air California, and we’ve been driving out to San Marino from our San Jose base for years. We know the difference between working on a 1990s tract home and a 1925 Spanish Colonial on Huntington Drive. San Marino’s estates weren’t built for central air. They were built for ocean breezes and gravity furnaces. That matters when your compressor fails at 102°F in August and you need someone who understands plaster-and-lath construction, not just a guy with a refrigerant gauge.
Call us at (844) 560-6978. We’ll answer, we’ll show up, and Marcus Feldman still reviews every San Marino job personally.
Why Crestview Heating & Air California Is San Marino’s Preferred AC Repair & Installation Company
San Marino homeowners don’t call us because we’re the biggest outfit in the San Gabriel Valley. They call us because we’ve spent nearly two decades solving problems that stump technicians who’ve only worked on post-1980 construction. Our 4.8-star average across 250+ reviews didn’t come from easy jobs. It came from retrofits where other companies walked away.
Marcus Feldman is our owner and our Service Manager. That means the same person who answers your questions on the phone is the one who checks the load calculations and signs off on the final walkthrough. No dispatch center. No rotating cast of subcontractors who’ve never seen a gravity furnace.
We carry factory-authorized parts for nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. Your system, our specialty. That phrase exists because San Marino’s housing stock is so varied, one brand loyalty would leave half our customers stranded.
Our response time to San Marino is consistently same-day or next-morning for standard calls, and we maintain emergency HVAC availability for compressor failures, refrigerant leaks, and total system outages during heat waves. When Santa Ana winds push October temperatures back to 95°F, we know who’s still running their AC hard.
Our AC Repair & Installation Services in San Marino
AC Repair
San Marino’s inland location at 600–700 feet elevation means summer highs regularly hit 100–105°F, far above what coastal LA experiences. That sustained heat load exposes every weakness in your system. We see a lot of capacitor failures on aging units that short-cycle because they’re undersized for 4,000-square-foot homes with poor insulation. Our AC repair calls in the 91108 and 91118 ZIP codes average $150–$650, depending on whether we’re replacing a contactor or rebuilding a compressor electrical panel.
AC Installation
This is where San Marino gets interesting. Most of your neighbors’ homes were built between the 1920s and 1950s, before central air existed. Retrofitting ductwork means threading 10-inch supplies through original plaster-and-lath walls, navigating beamed ceilings, and preserving historic millwork that can’t be replicated. We recently retrofitted a 4,000 sq ft Tudor on Lombardy Road where the original 1940s gravity furnace had a cracked heat exchanger. Our crew had to snake 10-inch supply ducts through the attic and between lath channels, using a Carrier 3.5-ton system with a low-profile air handler to preserve the living room’s original beamed ceiling. AC installation in San Marino runs $3,500–$7,500, but the real cost driver isn’t the equipment. It’s the labor to install it without destroying what makes your house valuable.
AC Replacement
When your existing central system hits 15–20 years, replacement becomes a question of efficiency and capacity. San Marino’s building department is notably strict about equipment placement and aesthetic impact on historic residences. We’ve replaced systems where the previous contractor installed an oversized condenser that the city flagged during a real-estate transaction. Our AC replacement process includes fresh Manual J load calculations, permit documentation that satisfies San Marino’s inspectors, and equipment selection that fits both your cooling needs and your home’s architectural character. Same $3,500–$7,500 range, but with the documentation to protect your resale value.
Refrigerant Recharge
Low refrigerant in San Marino usually means a leak, not normal consumption. The thermal stress of 100°F days accelerates corrosion at coil joints, especially on systems that short-cycle from poor sizing. We don’t just top off your R-410A or R-32. We pressure-test, locate the leak, and give you a repair estimate before adding refrigerant. A blind recharge without leak repair is throwing money at a problem that’ll return in six weeks.
Compressor Repair
Compressor failures in San Marino often trace back to electrical issues, not mechanical wear. Voltage fluctuations during peak summer demand, combined with dirty condensers that can’t reject heat, cook compressors prematurely. We test amp draw, check capacitor tolerance, and verify condenser airflow before condemning a compressor. Sometimes it’s a $200 hard-start kit and a thorough cleaning. Sometimes it’s replacement. Either way, you’ll know exactly why before we proceed.
Capacitor Replacement
The most common summer repair we make in San Marino. Capacitors degrade faster in heat, and San Marino has plenty of it. We stock dual-run capacitors for Goodman, Rheem, Lennox, and Trane systems, and we test both the capacitor and the compressor amp draw to catch underlying electrical stress.

Trusted Brands We Service in San Marino
We maintain active dealer relationships and parts inventory for Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For San Marino’s historic homes, we find ourselves installing more Trane and Carrier systems with low-profile air handlers that fit tight attic spaces, and Lennox variable-speed equipment that handles the extended cooling season without the noise that would disturb carefully preserved residential character. Goodman and Rheem remain popular for secondary structures and guest houses where budget matters more than whisper-quiet operation. We don’t push one brand. We match the equipment to your house, your budget, and your tolerance for sound.
Common AC Repair & Installation Problems We See in San Marino Homes
- Sizing failures from ignored load calculations. Undersized units short-cycle brutally on 100°F days because the original load calc didn’t account for poor insulation, single-pane windows, and zero existing ductwork. We redo Manual J calculations on every San Marino installation.
- Condensate drain clogs from plaster-wall humidity. Original plaster walls trap moisture differently than modern drywall. High summer humidity leads to condensate backups, water damage, and mold claims. We install secondary drain pans and float switches as standard practice in pre-1950 construction.
- Permit violations on “simple” furnace swaps. San Marino’s building department requires detailed documentation and inspections on any work touching historic residences. Contractors who skip permits routinely get caught during real-estate transactions, triggering holds and expensive retroactive compliance.
- Legacy gravity furnace disconnections without proper closure. Those original octopus furnaces connected to floor registers can’t just be capped and forgotten. Improper disconnection creates safety hazards and code violations that surface during home sales.

What moves you within these ranges? Equipment accessibility matters enormously in San Marino. A condenser replacement on a ground pad behind a 1930s garage is straightforward. Running ductwork through a finished attic with original redwood framing is not. Permit fees and inspection scheduling add cost and time that newer cities don’t impose. We quote upfront, in writing, before any work begins. Estimates are free. Call (844) 560-6978.

FAQs — AC Repair & Installation in San Marino
Yes, in most cases we can install central AC without removing plaster walls. We route flexible ductwork through attics, basements, and existing chases, using low-profile air handlers designed for tight spaces. The field vignette on this page describes exactly that approach on Lombardy Road. Every San Marino retrofit requires careful planning and a building permit, but destruction of original finishes is not the default. Call (844) 560-6978 and we’ll walk through your specific floor plan.
Manual J is the engineering standard for sizing HVAC equipment, and San Marino’s large pre-1950 homes deviate so far from modern construction assumptions that rule-of-thumb sizing fails consistently. A 4,000 sq ft home with plaster walls, minimal insulation, and original single-pane windows has a radically different cooling load than a new build of the same square footage. Undersized equipment short-cycles, wears prematurely, and can’t hold temperature on 105°F days. Oversized equipment dehumidifies poorly and wastes energy. We perform fresh Manual J calculations on every San Marino installation, and we document them for permit submission.
Yes, though it’s rarely a direct swap. Wall heaters have no ductwork, so we design a new distribution system from scratch. In San Marino’s historic homes, that usually means attic-mounted air handlers with duct drops to ceiling registers, preserving floor plans and wall finishes. The wall heater location becomes a return air path or gets sealed properly. Cost falls in our standard $3,500–$7,500 installation range, with complexity depending on attic access and structural constraints. We’ll inspect your specific layout at no charge.
We most often recommend Trane, Carrier, or Lennox for San Marino’s historic properties because these manufacturers offer the quietest variable-speed air handlers and the most compact indoor units for tight attic installations. Goodman and Rheem work well for secondary structures or where budget is the primary concern. We do not install brands we cannot service with factory-authorized parts. Your system, our specialty means you get equipment we stand behind for the long term.
Yes. San Marino’s building department requires permits for compressor replacement, and they enforce inspection compliance more rigorously than most neighboring cities. Contractors who skip permits create liability that transfers to homeowners during real-estate transactions. We pull permits on every job that requires them, schedule inspections, and provide you with final approval documentation. The permit process adds a few days to the timeline but protects your property value and eliminates the risk of city-mandated rework. Call (844) 560-6978 for an exact quote on your compressor replacement, permit included.
