How We Diagnose and Repair Your System
Most central air conditioning issues come down to one of three areas: the refrigerant circuit, the electrical components, or airflow across the coils. A refrigerant leak, a capacitor or contactor on its way out, a frozen evaporator coil, or a condenser buried in yard debris can each stop cooling in its tracks — and each calls for a different repair. We measure pressures, amp draw, and the temperature split across the coil before we ever open up the equipment, so we're fixing the actual cause rather than guessing.
When an AC won't start at all, it's often an electrical issue. A weakening run capacitor, a contactor with worn or pitted contacts, or a tripped high-pressure switch can all leave a unit humming or completely silent when the thermostat calls for cooling. We test each of these with a multimeter instead of swapping parts on a hunch — if a capacitor reads within spec, it stays in.
For refrigerant leaks, our priority is finding the leak itself, not just recharging the system — topping off refrigerant without a repair just buys a little time before the same problem returns. Once we've located and sealed the source, we recharge to the manufacturer's exact specification and confirm performance with superheat and subcooling readings rather than a rough estimate.
