Johnstone Supply

I have been a Johnstone customer for over 20 years, and this location is among the very best. The team is consistently helpful, knowledgeable, and responsive. I also appreciate that they sell exclusively to contractors, which keeps the store efficient and prevents long lines caused by homeowner or handyman returns. Their inventory is extensive, and on the rare occasion they don’t have a part in stock, they are able to source it quickly. Local delivery service is another major benefit, saving both time and effort. Overall, this Johnstone branch provides outstanding service and convenience, and I will continue to rely on them for my supply needs.

The team at the Valencia Johnstone branch is awesome! They’re always super helpful and go out of their way to take care of me. If they can’t do something, they’ll still work to find a solution. The counter guys are all friendly and know their stuff, and I always have a great experience whenever I stop by.

Johnstone's Valencia is fantastic. Ryan and his team are always on top of things; they always have my equipment ready when I order it online. They have been helpful with ordering warranty parts. Would highly recommend them to any HVAC company that hasn't used them before.

I've been coming to Johnstones for over 20 years now and although I've seen employees come and go, the store as a whole has always kept the same friendly, knowledgeable, and professional service standards that is honestly not seen in any of the many other suppliers I work with. I've known most of the employees for over 10 years and look forward to having an excuse to go buy something from them.

The boys at Johnstone supply are very helpful and knowledgeable I like coming in and being helped knowing I got the best services I work for Nicholas aire systems and I would recommended any contractor to come in and get helped by the team at Johnstone supply especially my guy over there Louie he’s very good at his trait and always provides A1 service and helps out with the knowledge he provides
