Johnstone Supply

As an HVAC contractor, Johnstone Supply has been an essential part of my business. Their customer service is solid and professional. Sometimes you need to wait a bit until a salesperson is available, but once they are, everything gets resolved quickly and efficiently — no runaround, no excuses, just solutions. Their online interface and product catalog are excellent and easy to navigate. In 99% of cases they have the parts I need for furnace and air conditioning repairs in stock, which saves a tremendous amount of time on service calls. Most of my testing and diagnostic tools are purchased here as well — prices are fair, and equipment is reliable. Johnstone also provides training and technical classes for contractors, which I really value. It shows they care not only about selling produc

Counter always helpful, we'll stocked with what I need to do my job. Lots of tools and display area very clean and organized. Fair prices, online system very easy to use. Pickup alays a breeze.

I needed a simple button style high limit switch, I called and the boy who answered says they have it yet he won't sell it to me and i need to call a professional when it is literally one of the most simple parts to swap on the consumer side of furnace repair. Last time I checked I didn't need a license to buy a thermo switch. Wouldn't it be more unsafe to keep trying to use a furnace that has a know bad part (tested with multimeter). I am extremely dissatisfied, it would be like if i called advance auto and requested a fuel filter and they told me working on my own car was too dangerous and they cant sell me the part, what a joke.

I must be honest , I read a few bad reviews and was Hesitant about going to this . I alway look for bad reviews lol. Im currently enrolled in trade school at MCC & I needed a manifold & hoses I thank god I didn’t listen to the bad reviews . This store was fantastic, the staff was friendly and very knowledgeable. I wanna give a special thank to one of the staff members his name is Mark . This guy was a blessing I couldn’t thank him enough he did everything in him power to make sure I got what I needed even tho I had a low budget he made it work so thanks again mark if you see this

Johnstone supply is an asset to HVAC community and many other trades. I have been dealing with them for many years and would highly recommend to other companies.
