Lacking knowledge, poor customer service. They sent over a kid whose first words were "I don't…read moreknow a lot about the problem you're having." The "technician" was on the phone the whole time with someone who knew more about the subject. He rearranged some wiring and left and within a couple of hours the upstairs was 80 degrees and the downstairs 60! He came back and just put things back to the way things were. He told us he would look into options and get back to us. Not only did we get billed for the whole thing, without a diagnosis and certainly not a fix, we never did hear back from them about potential options. The kid did return the next day, to retrieve the tool box he had forgotten behind! I did contact the owner, who was completely defensive of what had happened and completely unwilling to 1) work harder to fix the problem or 2) waive any portion of the bill for the inconvenience, lack of diagnosis, lack of fix, $400 for his apprentice to dink around in our basement for an afternoon hardly seems worth it! He also removed quite a bit of foam from our dampers that I had to replace. Save your money. What makes this all the more infuriating is that I did diagnose it myself, there was a broken motor on one of the dampers. $100 and 20 minutes later and everything works fine. The owner, as part of his dismissal, said that our system was out of date and that's why no one knew how to fix it, but the only reason we called Intermountain to begin with is because they are the ones who installed it 10 years ago and left their sticker on the system! Highly Recommend Sleeping Giant HVAC who followed up my own repair with excellent service to get the whole thing in working order.

I called Jaks to get information on replacing my boiler and hot water heater, and James, the owner…read morecame out personally to asses my situation and help me out. After hearing all my concerns and ideas, he suggested something that I hadn't thought of and that was a mini split. I had no idea that you could get a system that worked from the outside of the house that both cooled in the summer and heated in the winter in one unit! We ended up not getting the water heater from him, but we did get the mini split, one in the living room and one in the bedroom, and they work very well. Not quite as good maybe, as a forced air system, but certainly better and more quietly that large window air conditioners, which I previously had. What a relief!! I didn't know these mini splits even existed. Thanks for the heads up James, and thanks for helping us!

Technician showed up promptly at scheduled time, conducted a very thorough inspection of the AC components. He was not able to identify a specific issue, however the capacitor was a bit out of spec, so had him replace it since the unit was already disassembled. The issues I have with the service is 1. No report of the tests done and findings during or after service other than verbally.2. We were charged $240 to install the $30 part and the unit was already tore down from the inspection.

The other tech bit his tongue at least, but I cant believe they let that other guy go out in the field dealing with customers.

Nick responded quickly to my call to service our HVAC system that failed during a heat wave. Told…read moreme he would be at our house next day (Thursday) to assess our system and provide a quote. He called before arriving, to confirm visit. Wanted to diagnose our AC unit, even though it wasn't a service call. Determined the capacitor was bad and compressor was not repairable. Checked our furnace and gave us a quote. I asked when and he wanted to confirm a cancellation early the next week. Called us and offered to replace our system Tuesday. Yep, Tuesday sent a message they were coming at 9 am. Nick and his technicians arrived on time and finished replacing our HVAC system by 5 pm. Very professional crew, courteous, and never stopped till the job was done. Clean up everything and hauled it away. I offered to give him a 5-star recommendation, but he said 4-star got more attention. So, here's the 4-star for an excellent installation. Highly recommended. And, he billed his quoted price.
