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.
Imperial Beach combines severe salt exposure with a lot of small rental cottages, which shapes the typical project. A 900 to 1,400 square foot beach cottage near Seacoast Drive usually gets a coastal-rated two or three zone mini-split heat pump rather than central ducting, since there's no attic space to retrofit. Absentee-owner and rental property work is common here, and permits route through the City of Imperial Beach, generally faster to clear than Coronado's historic review since most of the housing stock isn't under design review.
Coastal installs need corrosion-resistant coil coatings and salt-rated cabinets on anything within a couple miles of the water, and that hardware costs more than standard equipment. The top of the range assumes a coastal-grade condenser, not a base unit.
| 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 Imperial Beach and Coastal 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.
A two to three zone coastal-rated mini-split heat pump for a 900 to 1,400 square foot cottage typically runs $9,000 to $16,000, a few hundred to a thousand dollars more than the same system inland because of the corrosion-protected coil upgrade. It's still cheaper than trying to retrofit central ducting into a home this size, which usually isn't practical anyway.

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.
