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. Chris Monier Reached out to Gem Heating and Air Conditioning after finding out our dryer vent was not up to code and a potential fire hazard. James came out the next day, went over quotes with different options, explaining the pros and cons of each, wasn't pushy whatsoever and didn't try to upsell us. We decided a direction and he came out and completed the work the next day. The work was done quickly and they left my space cleaner than they found it. Will 100% be using them for any HVAC needs going forward. 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. Danny Warn If you are looking for a small local business, that will look you in the eye and tell it to you straight, you found the right place Bonnie Olswanger James came over to diagnose a potential gas leak coming from a line under our home and was super respectful and extremely helpful. Thank you for such great service and for giving us peace of mind! Mike James did a great job installing a new hot water heater on our property. He also agreed to inspect 3 questionably installed mini splits. All in all, we were very satisfied with the service he provided and wouldn't hesitate to recommend him to anyone looking for plumbing or HVAC service. Cameron J Gem Heating & Air is awesome! They were able to come out and troubleshoot my issues quickly and gave me several price options to choose from and I never felt any pressure to over buy. All my questions were answered and the few concerns I had were resolved through pleasent conversation. Quality of work was top notch. Professionalism was among the best I've worked with. I absolutely reccommend Gem Heating & Air. Garrett James and Ezra came out within about an hour to help me get my AC unit back up and running. They were very friendly and professional and made sure I was well educated on what my options and costs were and even told me what to look out for in the future with that AC unit to stay ahead of any problems. I can’t thank them enough. Bryce Straub James and his daughter Mila are true professionals. I've had issues with my AC for the last 4 years and have had several companies come out and not solve the problem. James came out and diagnosed thee problem in an efficient and professional manner that left no doubt what the problem was. He was very friendly and was able to describe cause to my complaint, why it was the cause, and also provided the solution. Thankfully this time it was a cheap fix. Finding good repairmen is a challenge these days and once you find one you better hang onto that number. We will be holding onto his number for ourselves and passing it around to everyone. Thanks again James and Mila from Gem Heating and Air
