Johnstone Supply San Bernardino

Majid M. Seraj, Pharm.D.

stay away from this shop! i was installing a mini-split unit, and needed A flashing panel. they didn't know what i was talking about despite showing them a picture. they ordered something for me, but it was NOT what i needed. at the time of purchase, they did not tell me that i could NOT return it. level of knowledge sucks, customer service sucks! go here at your own risk.

Horrible customer service, especially from guy named John, works there.I'm an hvac contractor, that's been in the hvac industry for 30+ years. I know many contractors. RE Michaels is the place to go. Never Johnstone.

This is an excellent supply house. Fast, friendly and well informed personnel. Very clean and good location. Fair prices also. Thanks Johnstone for all your help and good products.
