Air Conditioning Repair

Air conditioning repair is a general term that covers a lot of possibilities, so on this page I'll talk about it in a general way.

Also for new technicians, our Air Conditioning Tools page has some guidance about tool selection, and our Air Conditioning Vacuum Pump page has tips about using and caring for your vacuum pump.

Air conditioning repair can be hazardous even for experienced technicians, so if you haven't worked in this trade yet, be careful.

Don't open a unit to troubleshoot it in pouring rain.

Your multi-tester will get wet and might be ruined, the electrical components in the unit will get wet and might fail if they get soaked, and any new electrical parts you handle in the rain might get soaked and fail.

If you're not familiar with air conditioning repair procedures, don't go drilling into the sides of air conditioning equipment, or banging on copper piping, or cutting wires or piping unless you know how to tag out and lock out the circuit, and verify that the wires aren't energized and that the piping has been evacuated.

Electrical shock or a blast of liquid refrigerant mixed with oil can definitely ruin your day;

And the damage will be compounded if you're working on top of a ladder or up on someone's roof without a safety harness, and get knocked off.

I hope this page has helped you stay out of trouble, and also helped you find the information you need to get your unit up and running.
