Johnstone Supply

I have been doing business with Johnstone Supply for many years and they are simply the best. I use to believe that customer service was nonexistent in 2024, but they have changed that. The customer service is outstanding and Mr. Ryan at the Katy location always goes above and beyond to make sure I’m satisfied. You can ask any of the other frequent customers about him and they’ll say the same thing. He knows his customers on a first name basis and is knowledgeable about the HVAC products they sell. I will continue doing business there and recommend them to anyone. Keep up the great work!!

Johnston supply in Katy service is excellent!!I been buying from them over a Decades . The new manager Ryan has Been a GOD Send. Any Equipment or parts I need he takes care in ordering it and have the equipment ready if it available or ready at another branch promptly if they don’t have it. Another great aspect is any part that from a particular branch that the company doesn’t sell 70%of the time it can be ordered thru the company, an Ryan gets it done very quick which makes my Customers very satisfied and I’m very satisfied 10 plus STARS FOR ME 😎🙏🏾!!

I purchased a motor for my AC unit and the employees that helped me were super knowledgeable! First time homeowner and have never replaced any hvac. But Justin and everyone else that helped were easy to work with and helped me find the right part when I was about to buy the wrong one!

Ive never been disappointed visiting Johnstone Supply Katy. The manager and sales guys are quick to take care of customers. Theyre familiar with their products and make great recommendations.

Friendly customer services, very quick and swift to respond. They will get you just what you need, Ive never had a problem purchasing here.

Staff is knowledgeable and friendly. The branch level employees really go the extra mile to take care of their customers.

My husband purchased a part for our broken A/C unit. The employee who was helping him sold him the wrong part. When we went back a few days later to get the correct part, a second employee asked the same questions as the employee who sold to us the first time. This time they recommended something different and we were sold a different part. How unprofessional that they will not refund for the unused part that THEIR employee sold us said we needed based on the specifications we provided. It’s no secret that these are hard times. Now we have spent double the money and will likely never get the full amount we paid for the wrong part. We will not support this business again.

Great customer service very helpful in Katy.Jason made sure I got what I needed to do the job right.

JOHNSTONE SUPPLY OF KATY AREA you Have one employee that needed help how to respect any customer that enter your store.. Your place do not deserved to be called PROFESSIONAL If not all customer are welcome and not treated right.. I would like to post a picture of him here since he does not want to show or give his name but let me respect him as I want him to respect my husband.

Justin has always taken care of everything I have ever needed. The staff is friendly and the store always looks clean.

Ive never had a problem with the guys at this location BECAUSE IM A LICENSED CONTRACTOR. Johnstone Supply only sells to licensed contractors. If you are a homeowner, then you need to call a technician to service your air conditioning equipment. Its not the job of the guys at the parts house to diagnose your equipments problems for you.

Manger Ryan was fast and had great service

Great service good guys. business as usual.Special note for the other reviewers.This is a HVAC supply house for licensed professionals. If you are a homeowner do not expect them to diagnose your HVAC system or tell you what parts you need. They are not obligated to sell parts to you. Especially if you have no idea what you are doing.

I am a licensed HVAC contractor and a Johnstone Supply customer for over 20 years. I have always received great customer service from all of Johnstone Supply branches. I just want to point out to the negative reviews Johnstone Supply clearly indicates wholesale only with no sales to the general public.

Not helpful at all. I had an old capacitor that did not have the marking on it due to rust. I took all the specs of my 3 Lennox AC system with me and was going to buy capacitors for all three units. The guy behind the counter spend two minutes typing on his keyboard and said he couldnt help me and that need to call Lennox because they were not a Lennox shop. I went to the next closes place and the person behind the counter actually applied some effort and helped me figure out the capacitors that I needed. The second place was not a Lennox dealer either they just put some effort into the process and took care of the customer standing in front of them. I wasnt a big sale but I ended up buying a motor and 3 capacitors and spend north of $450 with PartsCo on HWY6.

Justin and Brandon are great guys! They both know the business very well. Never an issue at this location. Keep up the good work!

Used to be a good place to come too and I wish I could give him higher than 1 star but they dont sell to the public anymore. I can understand not selling stuff that requires EPA certifications, but a bottle of pan tabs or a multimeter?

Dont go to this places, the white guy cashier are racism

Never had a problem with these guys. Have used them on several occasions for parts and equipment I could not find anywhere else. I am a Licensed Contractor.

Thank you for your assistance in answering all my questions.You made my decision very easy.

No help at all. Im surprised they know how to find the parts they have. Ive never been to a supply house that couldnt tell you anything about what they sell.

They have friendly service, well stocked and helpful, also great pricing.

Very professional and helpful people with excellent prices.

Great place the best prices , and they help you if you have question and advice you as well

They won’t sell you anything unless you trying to buy a lot of stuff . Don’t do business with them .

Supeeeeeeer slooooooow customer service. Thats why I just come here when its extremely necessary

NEED A LICENSE TO BUY A SEAL FOR A TEST HOSE, B.S. !!!! NOT DOING BUSINESS WITH JOHNSTONE !!

A model of inefficiency! Will take you longer to buy supplys for a job than the job itself!

Dont waste your time. This place is not open to the public.

Highly recommend!

Truely a great place to deliver.

So helpful!!

Gr a at service
