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.

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

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.

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.

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 products, but about supporting proper installation and long-term service. Overall, this is a trustworthy supplier with great resources for HVAC professionals. I am pleased to work with them.

Knowledgeable and dependable.

Milner Air was responsive, courteous, on time and professional. They got to the problem immediately and was able to have it fixed in less than 30 minutes. Highly recommended.

New air conditioning wall mount energy efficient heating and air units. These new units have helped us heat and cool our house much more efficiently, are quiet and provide exactly what we need to make our house much more comfortable. They did a great job and will continue to maintain our heating and cooling systems. Very experienced and trustworthy,

We had our heating system cleaned and a defunct humidifier removed. They installed a new A/C and compressor. All functions performed efficiently and professionally and cleaned up afterward. We are very pleased with all work done. Highly recommend.

Wow, will never use another HVAC company. Had a couple companies come into my store and give me an estimate for a pretty large job, they were $30K lower than the competitors because they chose to take the time to actually look at our entire system and come up with a creative way to use existing utilities. Very professional and have never felt like they were cutting corners and not doing their best on any service call, 2 very big thumbs up from me and will recommend them to everyone i know residential or commercial. Thank you Milner. Customer forever

Called Milner as a good friend recommended them when it was time to replace our 22+ year old a/c and gas furnace. Jeff and his crew were trustworthy and professional in every way and did a great job. Highly recommended!
