Adriana Maniere James was everything you want in home maintenance and repair. Kind, thorough, great communicator, and got the job done in one visit! We’re happy to be continuing our business with Gem! Galverg Maelstrom Very professional, got the AC up and running again within an hour, cleaned out the unit itself and was very kind all the way around. Would absolutely hire them again! Katie Coleman My wife and I came back from a trip and our air conditioner was not working. James came out last minute and diagnosed the problem instantly. Very professional and got straight to work. I would refer him to anyone that has HVAC issues. You’re the man James!!! Jessica Clay Great business and very honest! FC I called Gem after another company came out to diagnose my lagging AC and told me I needed 1lb of R22, but they didn't carry it. James was able to come by only a few hours after I called and did a full diagnostic and ended up adding 2.2lb of R22. He explained how my system worked and some sizing issues that are a part of my problem. I felt like he did a thorough job and explained things in detail which I appreciate. He didn't pressure me into a new system but let me know that I may need one in the next few years as mine is old and mismatched. I ended up purchasing their maintenance plan ($240/year) to help keep my system running as long as possible. Overall was very happy with my service. Brooke Ball I can’t recommend this company enough! James was on it as quick as possible. Very thorough with his work, and the process of doing things correctly. Very clean and very friendly as well. Great price and now we are even on his service plan monthly and it’s a huge weight off our shoulders with heating and air maintenance. This is definitely an easy 5 stars! Kaysha Weygandt Our HVAC stopped working on one of the hottest days of the summer when it was 107°F outside. We spent all day Friday trying to troubleshoot the issue ourselves but couldn’t get it figured out. Saturday morning we called Gem Heating & Air Conditioning, and James was able to come out within an hour. He quickly diagnosed the problem, explained everything clearly, and had our system repaired so we could get our home cool again during this Idaho heat wave. What impressed us most was James’s honesty and integrity. From the moment he arrived, we felt confident that he genuinely cared about fixing the problem—not selling us services or parts we didn’t need. He took the time to explain everything in a way we could understand, answered all of our questions, and made us feel like he truly had our best interests at heart. That level of transparency and trust is hard to find, and it’s exactly why we’ll be calling Gem Heating & Air Conditioning for any future HVAC needs. If you’re looking for a knowledgeable, responsive, and trustworthy HVAC company, I can’t recommend Gem Heating & Air Conditioning enough. Thank you, James, for getting us back up and running so quickly! Kyle Charles Awesome, knowledgeable, and most importantly, honest. James saved me a bunch of money and was able to trouble shoot my minisplit the same day. I’d rate 10 stars if I could. eric blair James came out to troubleshoot our AC and was very thorough and friendly. He took the time to educate us on the system and went out of his way to show us how things function. We appreciate his recommendations on how to love forward with maintenance and how to help us in the future. Matt Steeves James was a little early today but way better than being late! He was fast, knowledgeable and put my issues to rest and even got me set up for my fall maintenance. I would highly recommend Gem and James to anyone needing HVAC maintenance or repairs. James is the owner and operator of his business. You can tell by the way he treats his customers and handles business. Thanks again James for your honest, straightforward work.
