Johnstone Supply San Bernardino

Good customer service. staff is very friendly.

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.

DIYers beware: Johnstone only sells to people who are in the "club.' I went to this place for a blower run capacitor, a part that one can buy on Amazon for about $10. I just needed it "stat" as we have a rental and their A/C was down. The people seemed nice at first but the change of tone when one of the guys behind the counter learned I wasn't with "a company" was like Day & Night (pun intended.) He gave me a slip of paper (they had a stack of these next to the register) directing me to Mac's Electronics(!), whom they apparently use as a middleman for retail sales. He said that they have to "protect the trade" (I guess that means they want to force DIYers to pay one of their member companies $150 for a service call for a problem they've already diagnosed, plus pay for a ridiculously marked-up part - or make someone drive across town to Mac's for a marked-up part, wasting even more time and money.)

Fortunately for my situation, there was an HVAC technician in the parking lot who had overheard the exchange in the store and offered to sell me a new capacitor he had in his truck for $5! Crisis averted, and we were able to effect our needed repairs. Many thanks to that guy.

Caveat emptor to those looking for local parts: Get the items you think may go bad (capacitors, contactors, etc.) on Amazon and keep them around just in case! If you need them in short order around here you're out of luck.

Great store. The staff is friendly, knowledgeable and eager to help. Fair pricing and all the parts have a warranty unlike online retailers.

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.

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.

Good prices and quality

These guys really know how to take care of their customers!

Unfortunately they didn't have the copper air gap I needed other than that great place!!!

John on register gave me a really bad service.no more business with them.....
