We’re familiar with the specific headaches San Diego homeowners face: salt-air corrosion on coastal condensers, 1920s bungalows with zero ductwork, and the marine layer’s deceptive cooling that masks undersized systems until a heat wave hits. Marcus Feldman, our owner and Service Manager, has spent 19 years in HVAC and still manages jobs personally. That means when you call Crestview Heating & Air California, you’re talking to someone with skin in the game, not a dispatch center reading from a script.
Why Crestview Heating & Air California Is San Diego’s Preferred AC Repair & Installation Company
Our 4.8-star average across 250+ reviews didn’t come from cherry-picking easy jobs. It came from showing up in San Diego’s older neighborhoods where other companies either don’t want the work or don’t know how to handle it. We’ve installed three-zone mini-splits in Mission Hills craftsman homes with balloon-framed walls nobody wants to touch. We’ve replaced corroded condensers in Point Loma where the ocean air had destroyed four-year-old aluminum fins. San Diego customers remember that kind of specificity.
Marcus Feldman oversees every job as both owner and Service Manager. There’s no franchise layer, no outsourced project manager, no technician you’ve never met before who disappears after the invoice clears. From emergency calls to commercial buildouts, the same accountability structure applies. Your system, our specialty — and with factory-trained compatibility across nine major brands including Trane, Lennox, Goodman, and Rheem, we don’t turn you away because of what’s printed on the nameplate.
Our AC Repair & Installation Services in San Diego
AC Repair
San Diego’s coastal climate creates repair patterns you won’t see inland. In Point Loma (92106) and Ocean Beach (92107), salt-air corrosion attacks outdoor condenser coils with surprising speed. We routinely find refrigerant leaks and compressor strain on units that are only four or five years old — failures that would take fifteen years in Riverside or San Bernardino. Our AC repair calls in San Diego often start with coil inspection and electrical contact cleaning, not the generic “low refrigerant” diagnosis you’ll get from a tech who’s never worked the coast.
AC Installation
Here’s the reality most San Diego homeowners discover too late: if your house was built before 1980, you probably don’t have ductwork. Mission Hills, North Park, Hillcrest, Ocean Beach — these neighborhoods are packed with Spanish Colonial Revival and craftsman bungalows from the 1920s through 1950s that were heated by floor furnaces or wall units. Central AC was never part of the original build. AC installation in San Diego is overwhelmingly ductless mini-split retrofits, not central system swaps. We size these systems address-by-address because Mission Valley’s canyon heat (mid-90s) and Ocean Beach’s marine layer (upper 60s) are completely different loads despite sharing the same city name.
AC Replacement
When a 30-year-old Trane or Lennox finally gives out in a San Diego home that already has ductwork, replacement isn’t always straightforward. Older coastal units may have corroded line sets, deteriorated electrical connections, or pad mounts compromised by salt exposure. We assess the full system, not just the box that failed. In inland San Diego neighborhoods like City Heights (92105) or Lemon Grove, where central systems are more common, replacement timing often hinges on R-22 refrigerant phase-out and whether the existing ductwork can handle modern SEER2 equipment.
Refrigerant Recharge
A “simple” refrigerant recharge in San Diego usually isn’t simple. Coastal corrosion creates micro-leaks at flare fittings and service valves that evaporate refrigerant over months, not days. Recharging without finding the leak violates EPA regulations and wastes your money. We pressure-test and leak-detect first, then recharge with the correct refrigerant for your system — R-410A for most modern units, or discuss replacement options if you’re still running R-22.
Compressor Repair
Compressor failure in San Diego often traces back to one of three local factors: salt-air corrosion on electrical contacts, oversized systems short-cycling in Mission Valley’s heat spikes, or undersized ductless units running at maximum capacity during rare but intense coastal heat waves. Compressor repair versus full replacement depends on age, refrigerant type, and whether the underlying cause has been fixed. We’ve revived compressors in North Park bungalows and replaced them in Point Loma condos where the ocean view came with a four-year equipment lifespan.

Trusted Brands We Service in San Diego
We maintain factory-trained compatibility across nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For San Diego customers, this means we stock common parts locally and don’t need to special-order capacitors, contactors, or refrigerant valves for most service calls. Goodman and Rheem parts move fast in our San Diego inventory because those brands dominate the retrofit market in 92103, 92104, and 92105. Trane and Lennox components are stocked for the higher-end installations common in Mission Hills and Coronado. Daikin mini-split parts stay on hand because ductless retrofits are our bread and butter in this market.
Common AC Repair & Installation Problems We See in San Diego Homes
- Oceanfront condenser coil corrosion in Point Loma. Salt air within a mile of the ocean destroys aluminum fin coils in four years instead of fifteen. We find refrigerant leaks and compressor strain on units that look new but perform like they’re decades old. Annual coil coating pays for itself here.
- Oversized single-zone systems short-cycling in Mission Valley. The canyon traps heat, pushing temperatures into the mid-90s while coastal San Diego stays mild. Single-speed systems sized for peak load can’t modulate down, so they cycle on and off every few minutes, killing humidity control and compressor lifespan.
- Undersized ductless systems in Ocean Beach. Homeowners feel the marine layer’s cooling effect and spec systems for “typical” San Diego weather. Then a Santa Ana heat wave hits, and the mini-split runs flat-out without reaching setpoint. Proper load calculation must account for those rare but real 90°F+ days.
- Legacy floor furnaces with no path to central AC. In 1928 craftsman bungalows on Washington Street or 1930s Spanish Revival homes in North Park, there’s no chase space, no attic duct runs possible, no room for air handlers. The solution is always ductless, but many homeowners don’t know to ask for it.
Pricing for AC Repair & Installation in San Diego, CA
Here’s what AC work costs in San Diego’s market, based on our actual invoices across 92101–92115:
| Service | Price Range |
|---|---|
| AC Repair | $175–$765 |
| AC Installation | $4,130–$8,850 |
| Furnace Repair | $175–$825 |
| Tune-Up | $95–$235 |
AC installation at the higher end usually involves multi-zone ductless systems in older homes with complex electrical upgrades or structural mounting challenges. The lower end covers straightforward central system replacements where ductwork and electrical are already adequate. AC repair pricing depends on whether we’re replacing a capacitor or recovering refrigerant, brazing a leak, and pressure-testing — the kind of work salt-air corrosion creates. We don’t quote over the phone for installation, but we don’t charge for the estimate either. Call (844) 560-6978 to schedule.

FAQs — AC Repair & Installation in San Diego
Yes, the City of San Diego requires permits for all new HVAC installations, including ductless mini-splits, and the work must pass inspection. We handle permit submission and scheduling as part of our installation process, so you don’t need to navigate the Development Services Department yourself. Permit costs are itemized in your estimate, not buried in overhead. Call (844) 560-6978 to discuss your specific project.
Coastal units in ZIP codes 92106, 92107, and 92109 need annual service at minimum, and we recommend coil cleaning twice yearly if you’re within a half-mile of the ocean. Salt accumulation accelerates corrosion on outdoor condenser fins, electrical contacts, and mounting hardware. Inland San Diego homes can follow a standard annual schedule, but coastal conditions are genuinely harsher on equipment than manufacturer baselines assume.
Technically yes, but practically you’ll get better results from a ductless mini-split system. North Park’s 1920s–1950s bungalows have balloon-framed walls, finished attics with no chase space, and ceiling heights that make retrofit ductwork destructive and expensive. We’ve installed dozens of multi-zone mini-splits in 92104 that deliver zoned cooling without tearing into original plaster or trim. In a 1928 craftsman bungalow on Washington Street in Mission Hills, we found a rusty floor furnace from the 1950s still heating the home. With no ductwork and balloon-framed walls, we installed a three-zone Daikin mini-split system, mounting the outdoor unit on the rear patio away from ocean views to avoid salt-air corrosion.
Short cycling usually means your system is oversized for the actual cooling load, or there’s a restriction in airflow. In Mission Hills specifically, we’ve seen this pattern when homeowners install single-zone equipment rated for peak Mission Valley temperatures, then find it blasting on and off during the milder coastal days that are more typical. The fix is either proper load calculation for replacement, or in some cases, adding zoning controls to an existing system. Call (844) 560-6978 and we’ll diagnose whether it’s sizing, a failing thermostat, or something else entirely.
Replace it, unless the repair is extremely minor and you’re selling the home within two years. A 30-year-old Trane running R-22 refrigerant faces both refrigerant unavailability and efficiency standards that make continued operation expensive. In San Diego’s market, replacement with a modern system — or more likely, a ductless retrofit if your home lacks ductwork — typically pays back through reduced energy use within 5–7 years. We don’t push replacement for our margin; we push it when the math stops working for you. Call (844) 560-6978 for an honest assessment and free estimate.
