What a great company to work with. We worked with Scott Clark on having our HVAC unit replaced and he was always very responsive and was able to answer all of our questions and concerns. They replaced our unit and went over everything with us and the whole process was very stress free. We loved working with Scott and will continue to use JW Long Heating and Air Conditioning for all of our future needs. Thank you so very much!

Our heater stopped working a few days ago (of course at the coldest time of the year!) Brendon showed up when he said he would; he was pleasant and efficient, and he found the problem and fixed it in record time. I'm really impressed (and warm now). Thank you, Brendon!

Efficient install. Very nice. Answered my questions. Respectful of property and cleaned everything up when they were done. From experience I wanted a Trane and they accommodated my needs. I will be using them for regular maintenance going forward.

These guys came out and then send an estimate. Once I gave them the go ahead they came out quickly and replace all of my ductwork. I am looking forward to use the system. I would recommend to others.

I have been a customer of JW Long for 5 years; I bought a Trane unit for my home. I just installed a split unit in my FROG. One phone call; the split unit was installed within 10 days!! The staff at JW Long is as fantastic as a Trane Air Conditioner, quick, professional, reliable; most important friendly! I will b a lifelong customer. 5 Stars
