Heating & Air Conditioning / HVAC near Columbia Falls

“My combo boiler was blowing off water from the release valve almost nightly. I called Chris to troubleshoot and let me know what needed to be done. After several trips out to troubleshoot Chris was able to greatly reduce the frequency of this happening and installed a drain pipe for the water to drain in a bucket safely. He was honest and kept me educated on next steps. When the boiler needs to be replaced I’ll be calling Chris and his team. I highly recommend Chris and the All Valley Mechanical team for your HVAC needs. Thank you Chris!“

“This team is awesome!!! We needed help with some gas piping work, we met with Brandon to get the job organized and scheduled. Luke and Xandon arrived on time as scheduled. These two guys put in a long hard day but knocked the job out of the park! As a plus Luke kept me laughing and smiling the whole day. Highly recommend the Grizzly Team!“

“Friendly and efficient office staff. Very easy to schedule and timely. Technician was great. Did exactly what was needed in an efficient manner. Next day follow up from the office was a very pleasant surprise. Will definitely use them again.“

“So glad my neighbor recommended Great Northern. We had an estimate from a "big box" heating company but did not feel well served by them...After speaking to a neighbor we called Great Northern and so glad we did. Mark listened to our home heating needs, suggested two mini splits and a single ductless unit for another room that had an attic area above. Also suggested a larger mini-split then the first contractor for one area and based upon his math calculations for the room size we totally agreed. The crew's workmanship, profesionalism and comraderie during the two day installation period was wonderful. They also meticulously cleaned up and repositioned the furnishings, etc. All this and the final price tag was nearly $1500.00 less than the big box. To top it off, Great Northern even submitted the rebate info to Flathead Electric and we already received a check in the mail. Thank you Great Northern for your excellent work!“
