Wow! These guys did a really great job. I highly recommend J & K. They replaced our water and heating system and made what felt like a big, stressful job feel manageable from start to finish. These guys went above and beyond. They took the time to answer our questions, helped us through the whole process, and made us feel like we were in good hands. That kind of care sticks with you. Phil and Roman, thank you both. We’d hire you again in a heartbeat.

J & K is the best around! They gave the best price, did not try to upsell and do excellent work! Connor and Enoch did an excellent job. They worked clean and were very efficient. They were polite and very professional and their work looks good. They did both a furnace and ac install for me and I can't say enough good about them. I'm so pleased with the job they did. So glad I went with J&K!

J&K replaced the boiler for my water based heating system. I did research, got several estimates, then chose J&K. Their estimate was fair and their chosen boiler was highly rated. And their customers seemed to love them. Now I understand why.The technicians worked diligently, communicated well, solved every problem that arose, and moved pieces around so it was all efficient and unobtrusive. Then they cleaned up every speck. I applaud Kevin and Enoch.
