Not just new equipment — a system done correctly.

Central AC Installation

ABC Service sizes every system with a proper Manual J load calculation. Oversized AC short-cycles, leaves rooms clammy, and wears out fast — right-sizing is the single most important decision in the entire project.

AC Replacement

We install variable-speed and two-stage condensers from Trane, Carrier, Bosch, Mitsubishi, and Daikin, paired with matched coils. Inverter-driven equipment delivers 18–22 SEER2 in real operation and runs in the 50–60 dB range — barely audible.

AC Repair

Most AC complaints originate in the ductwork and airflow side of the system, not the condenser. We measure static pressure, isolate refrigerant and electrical faults, repair returns, and seal leakage so the system actually reaches setpoint without long, noisy cycles.

System Maintenance

Every system is started up with calibrated instruments: refrigerant charge verification, superheat and subcool measurement, and airflow balancing. Annual service preserves capacity, efficiency, and equipment life.

Why it matters

Why this is worth doing right.

Quiet operation

Modern inverter equipment runs in the 50–60 dB range — properly placed, you barely hear it.

Right-sized comfort

Oversized AC short-cycles, doesn't dehumidify, and wears out fast. Correct sizing is the whole game.

Efficiency

Inverter-driven systems hit 18–22 SEER2 in real operation — meaningful on summer afternoons.

Heat-wave readiness

Bay Area summers are warming. A well-designed AC system is now a baseline comfort and safety system.
