Anyone know how to repair hotel Ac's?
We have about 50 of our rooms blowing hot air and not cooling... anyone have any troubleshooting help for me?

Thanks in advance!

You just use standard procedures like on all other A/C units.

It is best to have a service man well versed in the HVAC trade to do the work.

A EPA certificate is required for handeling refrigerant/freon.

I do not relish the problems you have since those units can be a pain to work on.

Yeah... and unfortunately at the hottest point of the year my hotel is without a Maint. Man... so I have resorted to trying to figure out these units myself which HAS NOT been fun.

Good luck.
