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.

Sudden shutdowns usually trace to a tripped capacitor, a blown fuse, or a safety switch doing its job — a technician can isolate the cause during the first visit.
As a rule of thumb, a repair under a third of replacement cost on a system with years of life left is usually worth making.
Specialty parts on older or less common systems occasionally require an order, and we'll tell you that upfront.
