Johnstone Supply Denver

Terrible counter service, at least based on my one (and final) interaction with Johnstone. I walked in needing a slightly hard-to-find item and the gentleman behind the counter immediately started questioning my business credentials. He refused to clarify what his problem was, behaving like a condescending jerk -- inexcusable. He also uselessly suggested a different supplier that was totally inappropriate for my needs. I took my business to Grainger instead, where I had a completely delightful experience.

Great staff very helpful great service

I called Johnstone and asked for a part, and also asked if they sold to the public. I was told yes to both questions. I then drive over there - a 25 minute drive, only to be told they only sell to the trade. I was then sent to Federal heating supply where I had to pay 4x the real price (compared to Home Depot online) for the parts. Johnstone is participating in a ripoff scheme in which consumers lose out and trades make money that the consumer never even knows they're paying them for. In addition the counter person was rude an dismissive. If you're a contractor that honors your clients, avoiding Johnstone would be a gift you could give them. We need to break the gouging monopoly here in Denver - in the SF Bay area, there were always suppliers ready to sell to the public. Personally, I'm going to go get a contractor's license number to fool these greedy suppliers with.

For everybody complaining that they don't sell to you, because you do not have an account with them, you sound ridiculous. They are a WHOLE seller and have enough accounts to get by, without the DIY people of the world! With that said, they always have stock but if not are quick to order oem or have other options to finish the job! Turnover amongst the Employees is non existent. This is the go to place for hvac supplys and parts, that's if you have an account with them

The keep a lot of parts in stock with a great location with plenty of parking, only complaint is its a mad house having to wait 30 minutes to pull an order.

Excellent customer service, I mainly deal with Jerry Salgado at the counter and he takes great care of my company.

All my experiences here have been positive. Everyone I've dealt with has been super friendly and very helpful

Good place for residential, light commercial heating and cooling supplies and equipment. Lots of parts and equipment in stock. Ample parking and loading areas.

I choose Johnstone as my number one place to go. Compared to all the other HVAC suppliers in Denver, they are the most friendly, professional, and helpful than others by far.

Rob was phenomenal, helped me with everything I needed for a successful install.
