Melissa S.

Everyone on this team is fantastic, the techs are great! Thank you again Kurt and Austin for getting here so fast to resolve the issue, and Kelly for ordering the new part I needed for my furnace. Payton was also fantastic, I appreciate you all immensely. They always arrive in a timely fashion and Kurt had my new motor in and running in no time! I would highly recommend J&J Sheet Metal to my friends and family.

David B.

Kurt was absolutely fantastic! Showed up early, was quick to find a solution and got my A/C running within an hour! Highly recommend these guys! Professional, funny and polite all around makes for my new first call! Thank you, Kurt!

Doug V.

Contacted J&J to receive a competitive bid, I am glad I did. The company not only wants your business but works hard to get it. A/C and furnace were installed in one day, clean up was meticulous all at reasonable price. Service from the beginning to the end verifies my decision to go with them.

Ray W.

They had the best range of products to meet my needs and offered several choices. They helped me replace my old Lennox furnace with a new high efficiency one. Payton helped make the process easy and smooth. They work with Michigan Saves which got me great finance terms. The installation team worked late to make sure we had heat over the weekend. Big thanks to the whole team!
