Compressor wouldn't kick on during a heat wave and the tech had it diagnosed — bad start capacitor — inside twenty minutes.
Their tech traced it to a wiring fault at the thermostat and fixed it for a fraction of what I braced for.
Blower motor was pulling way more amps than it should and starting to smell hot.
Board threw an error code neither I nor the last technician could explain.
