These folks are professionals and thank goodness they serve the area we are moving to. I would not hire another company for Septic issues in the Flagstaff area. If you are having Septic issues hire these folks. They will take good care of you! George, Carlos and their team have a lot of knowledge, professionalism and truly care about their customers.

I was very pleased with the electrician when he came out to do an initial estimate. He was friendly and explained that this company enjoys helping home owners with these kind of electrical needs that I had at the time. The value seems to be a little higher than others but everyone has their own rates set. So I still think it's reasonable. I don't know how well the work would have been done, so I'm only reviewing the experience that I did have. 4/5 stars due to the communication issue. I called the office and spoke to a gal multiple times who was not relaying messages to the electrician. That's my only issue.

Danny, the project manager, listened carefully and worked with us to make things right. Mammoth returned to address an area that had been missed, and in the end they removed our additonal cost. That kind of follow-through and willingness to stand behind their work meant a great deal to us. The crew was courteous, professional, and helpful, and we appreciated the care they took with a situation that was both unpleasant and overwhelming. A company's character really shows when something doesn't go perfectly, and Mammoth handled our concerns in a way that left us feeling respected and well taken care of. We would definitely recommend them.

My experience with this company has been incredibly frustrating. In short, I do not recommend them…read moreand would not use them again. Details: Our house did not have a/c and our upper level was getting pretty toasty during the summer. After getting six quotes, we went with Master Mechanical. Our furnace covering the upstairs was over 30 years old so we decided to replace that at the same time. MM recommended a heat pump and furnace combo to address all our heating/cooling needs. Since install, we've needed MM to come out multiple times for various different issues that all amount to them cutting corners and doing a very sloppy install job. Ironically, when getting quotes, two of the more expensive companies warned us that a lot of contractors are cheaper, but cut corners during install, causing problems down the road. At the time I chalked that up to sales tactics, but now I wish I'd taken their advice more seriously. The problems started right off the bat. They couldn't get the a/c system to work after install. Supposedly it was a thermostat issue -- the old wiring for the thermostat wasn't compatible (whatever that means), and instead of just running new wire they went for the wireless thermostat option. They eventually got it working, but the wireless thermostat they installed wasn't a smart thermostat, which was in our contract. They came back and left some additional piece that could be connected to the thermostat to make it a "smart" thermostat. And I mean left it -- some assembly required by us that was not as simple as plug and play. Fall comes and we discovered our furnace for the lower level wasn't working. They didn't replace this one -- it's an older one, but it was in the same closet as the new one, so I figured something must have been unplugged or wiring messed with on this one while installing the new system for the upstairs. They come out and tell me some door shutoff piece was broken, not their fault. I can't prove it had anything to do with them, but this furnace was working beautifully with no issues the previous winter and I definitely didn't mess with the door so seems pretty clear to me what happened. But I sucked it up and paid that bill. Not long after, the new heat pump for the upstairs started having issues. It was working well for heating during the fall, but then temps dropped to a point where the heat pump should have shut off and the furnace would over, but it didn't. The heat pump just ran constantly trying to heat the house but unable to raise the temp anytime the outside temp was below 40. I called MM and they came out a week later and figured out they hadn't hooked up the wiring correctly so the furnace wasn't able to kick on. (I had asked after the install if they tested the systems and was told yes, but obviously they didn't test the heat). They "fix" the wiring and tell me it's good to go but I have to put the system on "auxiliary heat" (emergency heat) for the furnace to work. I ask, "so the heat pump won't work at warmer temperatures and then automatically kick over to the furnace once the temp drops enough?" They had no idea. Their solution was for me to manually change the heat source between normal and emergency heat for the two systems and they would come out again to add some outdoor sensor to see if they could make the transfer work on its own. How do you recommend and install a system and not know how it works??? Absolutely baffling. They topped it off by sending us a repair bill for the wiring issue, despite it being under the labor warranty and their mistake. I now have no faith this system will last and have considered hiring another contractor to come inspect it and make sure there's nothing else glaring. Do yourself a favor and go with someone else.
