I needed a capacitor for my AC unit and went to several locations, and may I add on their websites did not mention “Only Contractors”. Got turned away several times for not being a contractor! Finally found Johnstone Supply and they had my part and were willing to sell! OMG a business willing to do business! Thanks to these fine folks a customer went home happy and got his AC running again just in time for 100F heat;) awesome shop, great prices, and honest! Thanks for the sell Johnstone Supply!

One of the better locations. Other stores it can be hard to get a call back but these guys are willing to take the time to research parts and get back to you.

They are always helpful. Especially Lisa. They are fast and they always know what I need. Very knowledgeable and very friendly. I have never had a problem.

Johnstone supply store in montebello rocks! Best store. Always stocked in equipment and supplies if they dont have it they usually try and get it asap for you and they make it happen. Friendly staff that help you out with a good attitude even Miguel u may not see him but he is behind the counter with a smile as well. Lonnie pretty much knows everything about most equipment and very helpful. Thanks guys!
