DO NOT USE THIS COMPANY. Wow. Where do I begin? I called this company to come out to my house to look at my ground source heat pump which stopped working. I was not impressed with the guy they sent out at all. Nice fellow, but got the strong impression that he was not very knowledgeable about GSHP. Not to mention he was 1/2 hour late to the appointment. I was very shocked when 3 weeks later, I receive a bill for $280, claiming 3.5 hours of labor! He was at my house for a total of 1 1/2 hours, which is still a lengthy time to look at a 20 year old heat pump that clearly needed replacing. When I called to inquire about the bill, I was directed to CHUCK, who promised he would look into it, but that he didn't believe anyone they employ could be dishonest in any way. Huh. I called back the following business day to follow up since CHUCK never bothered to call me back. Again, he blew me off to say he needed to confer with his boss JERRY. Called back a third time two days later, and was met with the same indifference. By now I had had it, and demanded that the invoice be corrected. I also let him know about the reviews that are out over the internet regarding the service of this company. Good luck finding ANYTHING positive. I should also mention that if you are planning on installing a GSHP in the future, another reason not to use this company is that you will not get any rebate from Missoula Electric Cooperative for installation, as this company is not listed as a qualified company through bpa.gov. read more
