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 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.

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.

Went in today and guy at counter was refusing to help. Hispanic guy at the counter has bad customer service skills. Didn't want to check part availability. Don't worry, went across the street and got the part. US Air was much better with trying to help. Sad because I give a lot of business to the Oxnard and newbury park johnstones.

Horrible service!!! Don't bother coming here unless you like wasting your time. Should be called useless supply.

If you're in need of parts for a DIY job at home -- don't bother looking here. I needed a dual run capacitor for my central A/C -- and they wouldn't sell me one without a contractor license. I try to support local businesses over Amazon whenever I can -- but these guys are actually giving Amazon business that would have been theirs. How stupid is that? When I told him that Amazon was getting his business he snapped back with "we'll still be here". -- Not with my money.

Won't sell to end users, only contractors. Doesn't say so on their website.

My folks of 90+ years young gas furnace started to act up . pulled out the gas igniter and headed to Johnstone supply . Walked in holding the connector and asked the young man to guess the part number . This started a search of all available igniters once jarred saw the part number. 15 minutes later and 5 different models a direct fit replacement was found . working and bantering with Jarred was such a pleasure. This experience reminded me of years past of great customer service we don't see often enough any more . I just have to say Thank you jarred and the Valencia store !

What a piece of s*** company. Great business model to not sell to licenced general contractors. Only C20. Not even the public. The guy was a fu$%&g a$$ hole on the phone. My AC Cap went bad and I needed a new one quick. hotter than crap out. Wont sell. I hope the guy I talked to gets Covid and hope this company and any other with the same attitude and F'ed up policy goes under

I have had my plumbing contractor license for years. I am currently a first responder, working at this stores local law enforcement. My air conditioning went out late Friday night, all I needed was a motor for the blower. I have put in hundreds of motors over the years. This store would not sell to me because I did not have my c-20 contractors license. A gentleman out in the parking lot was nice enough to offer to buy the motor for me. When he walked in I heard them say " you are not trying to buy for that guy are you" referring to me. They refused to sell to that nice gentleman as well, even though they knew him. COME ON guys I have a family of six at home with no air conditioning 4 of them are small children. Never was I rude and I even thanked them for their time, even after the contractor was trying to buy it for me. I'm not telling anyone where to spend their hard earned money , but explore your options.

I've been coming to this business for about 6 years and have had the best costomer service and the best prices around. They will help with any questions or concerns about product.
