Thank you so much for fixing an apartment complex for us. I called 4 other companies and no one could help us until the next day. It was going to be 12 degrees and I was worried about my tenants and the pipes. John came out and got it fixed that night!

John and his team installed ductless mini splits in all three of our bedrooms and our downstairs living room. They were great in communication and getting our top of the line Mitsubishi systems as quickly as possible. They worked quickly, efficiently and clean! We really appreciate them taking such good of care of us just in time before summer. They also were very affordable after comparing multiple company estimates and did not try to sell us on more than what we needed. 5 stars!
