Johnstone Supply

When you walk into an HVAC specialty store, you don’t always know exactly which part you need. And this is the place where true professionals work — sometimes they understand the equipment even better than the technician. They will always help you, quickly find the right parts, and make the whole process easy. These guys are truly on the customer’s side. Fantastic place! I definitely recommend it to everyone in San Francisco. Throughout all my years of experience — this is the one spot where you really feel supported with a professional approach. ⭐️

Johnstone has some of the best customer service, always willing to help you find what you need and have a great stock of parts. They take The extra time to try and get you the parts you need. I highly recommend any Johnstone location for your HVAC needs.

Best place for find any equipment parts of any brands.

First time I made a purchase here. I was looking for mini split line sets, but a particular kind. Uv rated, 1/2" and US manufactured, etc. They didn't have what I needed in stock, But Edwin said he can get it pretty quick for a job I'm getting ready for. Instead of choosing to get me off the phone, he gave me options. Within a few days they had the line sets, and they followed up a few times with a status. Edwin was friendly, helpful, knowledgeable and followed through! I don't know why they have a 3.8 rating, they are 5 Star in my book!! Thx again guys!

Friend professional guys that know about what they are selling.
