When it comes to HVAC, you get what you pay for. Brennan H&C have installed a new construction furnace, as well as AC units in the same new construction, and my existing house - all the way in Bozeman. Tried to find a qualified and competent company in Bozeman and Kalispell, and they seem to be partially trained and marginally competent compared to the school trained guys that this company has employed. Would I use them again - hell yes. If they were local here in Bozeman, I would have them do our semi-annual maintenance on my organization's building. Keep up the great work. (Oh, and they also put in a new furnace and A/C unit at my folks house in GF, as well as an overhead garage heater. Flawless). Do your homework and you will find out why they are so good. I'm not willing to pay for work that continually needs "maintenance" because the first 3 guys didn't know what they were doing (which has happened here in Bozeman).

Great, super nice, rapid customer service from local family owned business. AC broke in the midst of a couple weeks of 90F+ heat (compressor went out on old R22 unit); they came out to bid the repair and had me back up and running with new AC unit installed the next day. Would call them again, no question.
