AC installation across San Diego County runs $6,800 to $16,000 for a complete system, installed, after a free in-home estimate. A standard single-stage system on a typical home lands toward the lower end. Variable-speed equipment, a heat pump conversion, or a home that needs duct work or a panel upgrade push it higher. Pricing is the same everywhere in the county, with no travel surcharge.
Boulevard sits at 3,200 feet along I-8 in high desert climate, hot dry summers and real winter freeze both apply, which means equipment needs genuine seasonal range rather than a mild coastal spec. Most rural large-lot homes here run on propane, making propane-to-heat-pump conversion the standard project. Permits route through the County of San Diego, and severe SDG&E power shutoff exposure makes battery backup a common consideration.
Mountain installs often mean dual-fuel configurations, a heat pump plus gas or propane backup, and longer line-set runs on larger rural lots, both of which add real material and labor cost. Add the drive time from the nearest service hub and this zone runs the highest install range in the county.
| Item | Typical cost | Notes |
|---|---|---|
| In-home installation estimate | Free | A measured quote in your home, not a phone guess |
| Manual J load calculation | Included | Part of every estimate, sizes the system to your actual home |
| Standard central AC system, installed | $7,000 - $10,000 | 14.3 SEER2 single-stage, the most common install countywide |
| Two-stage system, installed | $9,500 - $12,500 | Runs at low capacity most of the time, better humidity control |
| Variable-speed high-efficiency system, installed | $11,000 - $14,000 | Best comfort and efficiency, the highest equipment tier |
| Heat pump conversion, installed | $9,500 - $15,000 | Replaces AC and furnace with one system, qualifies for the largest rebates |
| Coastal-rated condenser upgrade | $400 - $1,200 added | Corrosion-resistant coil and hardware for homes near the water |
| Refrigerant line set replacement | $800 - $1,800 | When the existing line set can’t be safely reused |
| Mechanical permit | $250 - $500 | Pulled by us, inspection scheduled and included |
| Duct sealing or partial duct replacement | $1,000 - $4,000 | Quoted only if the duct inspection finds real air loss |
| Older-home electrical panel upgrade | $2,500 - $5,500 | Common on homes built before the 1980s |
Ranges reflect Boulevard and Backcountry San Diego. Your exact figure depends on the factors below. We quote flat-rate before starting.
SDG&E and TECH Clean California rebates apply to qualifying equipment, and they're largest for heat pump installs. The federal 25C tax credit can stack on top for equipment that qualifies. Exact rebate amounts depend on your home and the equipment you choose, so we confirm what you actually qualify for during the estimate rather than quoting a number up front. We also offer financing so a full replacement doesn't have to come out of savings all at once.
At 3,200 feet, Boulevard sees a wider temperature swing between summer highs and winter lows than most of the county, which means we size equipment for both peak cooling and peak heating rather than optimizing for just one. A cold-climate-rated heat pump handles that swing better than a standard model, typically for a few hundred dollars more, and avoids a system that performs well in summer but struggles in a real winter cold snap.

A complete system runs $6,800 to $16,000 installed, with most single-family homes landing in the $7,000 to $12,000 range. The free in-home estimate breaks out equipment, labor, and permit costs before you decide.
For most San Diego homes, yes, especially near the coast where humidity is higher. It runs quieter, holds a steadier temperature, and uses less electricity over a full season. On a smaller inland home with simple cooling needs, a standard single-stage system is often the more practical choice.
The in-home estimate and the Manual J load calculation are both free and included in every quote. On the installed system itself, a standard single-stage unit is the lowest-cost option that still comes with a full manufacturer warranty.
Yes. SDG&E and TECH Clean California both offer rebates, and they're largest for heat pump systems. The federal 25C tax credit can stack on top for qualifying equipment. We confirm exact eligibility and dollar amounts during your estimate rather than promising a number in advance.
