Mighty Pine installed a QUILT ductless AC and heating system and we are so happy with it! The company is very nice to deal with, and the technicians are top notch! We are glad we chose them!
My partner and I used Mighty Pine to check out our AC at the start of the summer season for routine maintenance. Neko did a thorough inspection and I was impressed by how professional, personable and informative he was. He gave us a heads up on services to consider to avoid
Great service. Sean was knowledgeable and friendly. He answered my many questions. I learned a lot about AC. We will stay with Mighty Pine for HVAC and also have them do a plumbing inspection of our house.
Neko came out to repair our a/c and did an outstanding job! Very professional, courteous, and thorough! Took his time and treated our home like it was his. Very impressive!
Great service! Highly recommend! Chris Duncan was our service tech. He was extremely helpful in explaining the recommended course of action and did a great job doing the repair. I'll be sure to call Mighty Pine should I need help with my mechanical equipment or plumbing. Thanks
