Emergency Diagnostics

Fast fault identification. Troubleshooting sensor failure, PCB short circuits, expansion valve freezes, and starting motor issues.

Surgical Troubleshooting

When a climate control system goes down unexpectedly, rapid and accurate diagnosis is critical. Simply replacing parts without understanding the root cause often leads to repeated failures and wasted capital.

Peekay Technician utilizes advanced multimeter testing and onboard diagnostic code analysis to pinpoint the exact point of failure. Whether it is a blown run capacitor, a faulty thermistor sensor, a sticking electronic expansion valve, or a fried printed circuit board (PCB), we isolate the component with surgical precision.

Once identified, we provide a transparent, fixed-cost repair quotation before any replacement work begins, ensuring you are in complete control of the repair process.
