Kari C Gem Heating and Air Conditioning have been great to work with. My furnace went out on a Friday and they were very quick to show up at my house immediately and diagnose and fix the problem to avoid an emergency call out over the weekend. James took the time to explain everything to me thoroughly and was very clear about my options moving forward. They are very easy to reach when needed, and respond right away when you have questions. The business is a local independent and family run business, making your interaction with them more personal. Would highly recommend this business! James Barrett Great service. Not the cheapest but they sure do great work! Wilderness Medic James was super nice and quick getting my AC repaired before the summer. Michelle Baker We had a great experience with Gem Heating and Air Conditioning. James came out and took care of our A/C problem this past fall and we were able to sign up with their maintenance program. We look forward to working with them going forward! We’d recommend them for all your HVAC needs. William Herd Our mini split system wasn't heating. James came out and got it diagnosed and up and running. There were some unavoidable costs, but he worked with us best he could and there have been no issues since. Great service, thanks James. Brian Bentler I highly, highly recommend Gem Heating and Air Conditioning!!! Lea Garcia Jax was very professional and made sure everything was in order. They worked on replacing my HVAC vents that were ruined after my leak. Carol L Chase They’re wonderful David “Aerothises” Fast response time, transparency, documentation, and personalization. I am happy with y'all's service call and look forward to working with you all in the future. I hired the company to come out and do a seasonal inspection, and they found a handful of items that the previous installers overlooked either in haste or carelessness. We put together a plan to keep the system running at peak performance after the initial evaluation that exposed issues that reveal a darker story for the other company I hired last year.
