"The whole experience with 3 Mountains Plumbing was outstanding from Nicole at the office to Jon Marc and Peter, the plumbers. They originally scheduled me for an appointment 5 days out, but Nicole watched appointments carefully and moved my appointment to the same day I called. Jon Marc, the plumber, was very knowledgeable and professional. He gave me different options, which allowed me to decide what worked best for me. He even gave me a teacher discount. After installing my water heater at 8:00 p.m. at night, he discovered a manufacturing problem with the water heater. He called another plumber, Peter. Peter was going off shift and was at the office, but got another water heater and brought it to my house so Jon Marc could install it! I think other plumbers would have said that they needed to come back the next day, but Jon Marc stayed until 10:00 p.m. installing the water heater. I will never use another plumbing company because 3 Mountains is the best! Nicole, Peter and Jon Marc... Thank you!"

"We called several HVAC companies for our ductless mini split, but Aviator was the only one that responded quickly. They fixed the issue the next day and saved us from replacing the whole system. Excellent service!"
