AC Installation in San Jose, CA
A new central AC installation in San Jose typically runs between $4,500 and $12,000 depending on system size, brand, and whether ductwork needs modification – and most installations are completed in a single day. At Crestview Heating & Air California, Marcus Feldman manages every our AC Repair & Installation services personally, bringing nearly two decades of hands-on HVAC experience to a process that most companies hand off to whoever is available.
If your current system is beyond repair, undersized for your home, or simply worn out after 15-plus years of Silicon Valley summers, a new installation is the decision that pays off fastest. We work across nine major brands, so you’re never steered toward a specific manufacturer because it’s the only one we know. Our job is to match the right system to your home, not move inventory.

When You Need AC Installation
Not every situation calls for AC Repair. Some systems have simply reached the end of a reasonable service life, and continuing to patch them costs more over time than a clean replacement. Here are the scenarios where a new installation makes the most sense:
- Your system is 15 or more years old. Most central AC units in San Jose have a realistic service life of 15-20 years. Once a system hits that window, repair costs climb and efficiency drops – often at the same time.
- Repair costs are approaching 50% of replacement value. A compressor failure or refrigerant leak on an older unit can cost $1,500-$2,500 to fix. At that point, the math rarely favors the repair.
- Your home was recently added onto or remodeled. Many older homes in Willow Glen and Cambrian Park were built before modern open floor plans became common. An addition or renovation can leave your existing system undersized for the new square footage.
- You’re seeing sharply higher energy bills without explanation. Degraded efficiency is one of the first signs a system is working harder than it should. A new Trane or Lennox unit with a high SEER2 rating can cut cooling costs noticeably in San Jose’s warm-season months.
- Your system uses R-22 refrigerant (Freon). R-22 has been phased out federally. Systems that still rely on it are expensive to service and impossible to refill at reasonable cost – replacement is the only practical path forward.
- You’re building new or converting from window units. If your San Jose home has never had central air – common in older Japantown and Rose Garden properties – now is the time to do it right with a properly sized, ducted system or a ductless mini split where ducts aren’t feasible.
Our AC Installation Process
We don’t show up with a unit on a truck and hope for the best. Every installation follows a deliberate process that Marcus oversees from start to finish. Here’s what to expect:
- Load Calculation and Site Assessment. Before we recommend any system, we perform a Manual J load calculation – the industry standard for sizing HVAC equipment. We account for your home’s square footage, insulation quality, window orientation, ceiling height, and local climate data specific to San Jose. Skipping this step is one of the most common mistakes less experienced installers make, and it leads to systems that short-cycle, fail early, or never cool the house properly.
- System Selection and Proposal. Once we know what your home actually needs, we present you with equipment options across brands like Goodman, Rheem, Lennox, and Trane – with honest comparisons on efficiency ratings, warranty coverage, and total installed cost. No upselling you to equipment you don’t need, and no steering you toward a single brand because it’s what we stocked.
- Ductwork Inspection and Modification (If Needed). Ductwork is often overlooked, but leaky or undersized ducts can undermine even the best new system. We inspect your existing duct system and identify any sections that need sealing, resizing, or rerouting before the new unit goes in. In some San Jose homes – especially bungalows built in the 1940s and 50s – this step makes a bigger difference than the equipment choice itself.
- Equipment Removal and Installation. We remove the old system responsibly, handle refrigerant according to EPA guidelines, and install the new indoor and outdoor units according to manufacturer specs and local San Jose permit requirements. Electrical connections, refrigerant charging, condensate drainage, and thermostat wiring are all handled in-house – nothing subcontracted.
- System Commissioning and Testing. Once the equipment is in place, we don’t just flip the switch and leave. We verify refrigerant charge, check airflow at every register, confirm the thermostat is calibrated correctly, and run the system through a full cooling cycle to make sure everything is operating within spec.
- Walkthrough and Documentation. Before we leave, we walk you through the new system – how to operate it, what the maintenance schedule looks like, and what the manufacturer warranty covers. You’ll have everything you need in writing.
AC Installation Pricing in San Jose
New AC installation in San Jose costs between $4,500 and $12,000 for most residential projects. That’s a wide range, and it’s honest – the final number depends on several factors specific to your home and the equipment you choose. Here’s how the pieces break down:
| Project Type | Typical Range (Installed) |
|---|---|
| Standard central AC replacement (existing ducts, single-story) | $4,500 – $6,500 |
| Central AC replacement with duct repairs | $5,500 – $8,000 |
| New central AC with new ductwork | $8,000 – $12,000+ |
| Ductless mini split (single zone) | $3,000 – $5,000 |
| Ductless mini split (multi-zone, 3-4 zones) | $7,000 – $12,000 |
What moves the number up or down:
- System size (tonnage): A 2-ton unit for a 1,200 sq ft home costs less than a 4-ton system for a 2,800 sq ft two-story in Almaden Valley. Proper sizing matters – don’t let anyone sell you bigger just because “more is better.”
- Efficiency rating (SEER2): California Title 24 sets a minimum efficiency threshold for new installations, and higher-efficiency units cost more upfront but reduce monthly bills. We’ll show you the actual payback period so you can decide what makes sense.
- Ductwork condition: Homes in Berryessa and North San Jose with original 1970s duct systems often need significant work before a new unit will perform properly. We quote ductwork separately so you can see exactly what you’re paying for.
- Permits: San Jose requires permits for new AC installations. Permit fees vary but are typically in the $200-$500 range and are factored into our quotes.
- Brand and warranty: Entry-level Goodman units and premium Lennox or Trane systems both have their place – the right choice depends on your budget, how long you plan to stay in the home, and how much you want to spend on energy each month.

FAQs – AC Installation in San Jose
How long does AC installation take in San Jose?
Most residential AC installations are completed in one day – typically 4 to 8 hours depending on the complexity of the job. A straightforward equipment swap on an existing, properly sized duct system usually lands on the shorter end. If ductwork modifications are needed, or if the installation involves multiple zones, it can extend to a second day. We give you a realistic time estimate before we start so you can plan accordingly. Call (844) 560-6978 for an assessment specific to your home.
Do I need a permit for a new AC installation in San Jose?
Yes – San Jose requires a mechanical permit for new AC installations, and we pull it as part of every job. Some contractors skip permits to cut costs or time, but that creates problems when you sell your home and during any future insurance claim. We handle the permit process, the inspection scheduling, and the documentation. It’s built into our process, not an add-on.
How do I know what size AC system I need?
System size is determined by a Manual J load calculation, which accounts for your home’s square footage, layout, insulation, window area, ceiling height, and local climate conditions in San Jose. Bigger isn’t always better – an oversized unit will short-cycle, wear out faster, and leave your home feeling humid even when it’s cool. We never size by guessing. Call (844) 560-6978 and we’ll run the numbers before recommending anything.
Is it better to repair my old AC or replace it?
A general rule of thumb: if your system is over 12-15 years old and the AC Refrigerant Recharge Cost in California, CA or other repair exceeds 40-50% of what a new system would cost, replacement usually wins over time. Beyond the math, there’s also the efficiency gap – a 15-year-old system might run at a SEER rating of 10 or 11, while a new unit starts at 15 SEER2 or higher. In San Jose, where cooling season runs from roughly April through October, that efficiency difference shows up on your bill every month. We’re happy to walk through the numbers honestly and help you decide – call (844) 560-6978 for a free estimate.
