Auto Repair Tech TipsNumerous things can be the culprit when your A/C is blowing air that isn’t very cold. There’s a good chance that your A/C system may be out of refrigerant. If it is, there could be a leak in your A/C system.The refrigerant is an invisible gas, which leaves no obvious signs when it leaks. In order to identify where the A/C system is leaking, all refrigerant must be evacuated from the system. Then the system is refilled with refrigerant containing a special dye in it. In most cases, you will leave the shop with cold A/C! If your system is leaking, the refrigerant will eventually leak out again. This time, the dye that was added will leave a “stain” at the location of the leak.

Our technicians will shine a special light over the system and the “stain” will glow in that light. It is at this point that the actual repair can be completed.

If your car is running poorly, or the light is flashing, get service right away! Check back soon for the latest tech tips! Contact us or call us at 218-963-2202 for more information about our auto services.
