A valve on the supply line to my water heater failed in the closed position, so I had no hot water in mid-December here in Flagstaff where the temps. get pretty low. Replacing the valve was not so easy because of residual water in the lines and the mess of pipes in the vicinity of the valve. So I called Intermountain and was able to speak with a person right away, no easy thing these days. The pleasant lady (Vanessa) was able to arrange a visit from one of her plumbers reasonably soon, given the time of the year, when lots of repair work is called for in this area.

Reviews
I am the manager at Allguard Self Storage. I’ve been here almost 4 years and up till then the a/c and heating had only been serviced as needed. Coming from a commercial real estate background, I felt the need to have annual PMs performed - especially given the fact the equipment was 30 years old. After trying a few different companies and not being happy with them I found this one - I found I made the best decision. They are reliable, knowledgeable and trustworthy. I am very comfortable with them and I know our equipment is in good hands.
Intermountain recently installed a furnace in my in law suite and did a great job! They are my go to for any heating system or plumbing needs!
The office staff is responsive and professional and the service techs are always prompt, helpful and knowledgeable. Would highly recommend Intermountain.
