"Jeff and his team did and excellent job with the installation of two Daikin HVAC units. I had many questions about the units and install and they were quick and thorough in responding. The price and warranty were competitive with high end brands. The crew was courteous and professional during the two day install. They were the only company that included replacement of the coolant lines, rather than just flushing the old ones. So far the Daikin variable speed AC units are exceptionally quiet and the house is very comfortable. Would recommend Ace Home Services and Unique Comfort without reservation."

"A Raving Review for Green Mechanical LLC! If you’re looking for the absolute best HVAC service around, look no further than Green Mechanical LLC! This company is truly a gem, and I couldn’t be more thrilled with the incredible service they provided. My heater had been misdiagnosed by another company, leaving my family and me in the cold—literally! Thankfully, I called Green Mechanical LLC, and they completely turned things around. From the moment I called, I knew I was in good hands. Devin Green, the owner himself, came to my house to personally assess the issue. This level of dedication and care is something you just don’t see every day! Devin’s professionalism, deep expertise, and genuine commitment to solving the problem made all the difference. He didn’t just slap on a temporary fix or rush through the job—he made sure to thoroughly diagnose the issue and explain every step of the process to me. A huge shoutout to Jacob and G, who also worked on my system. They were punctual, knowledgeable, and incredibly respectful of my home. Their teamwork and attention to detail were top-notch, and it was clear they take immense pride in their work. Thanks to Devin, Jacob, and G, my heater is now working perfectly, and my family can finally enjoy a warm, comfortable home again! I also want to emphasize how important it is to support small businesses like Green Mechanical LLC. These are the companies that truly care about their customers and their communities. Devin and his team are local experts who go above and beyond to deliver top-notch service, and they deserve every bit of your trust and business. If you need HVAC services—whether it’s a repair, installation, or just regular maintenance—do yourself a favor and call Green Mechanical LLC. Their commitment to excellence, fair pricing, and outstanding customer service make them a company you’ll want to recommend to everyone you know. Thank you, Devin, Jacob, and G, for your amazing work and dedication. You’ve earned a lifelong customer! 🌟"

"4/29/23 Christian tech checks our our home AC. He notes the cooling coils are rusty, a source of coolant leak, and the system, at 14 years age, is near it's end of life. He also noted some mold in the blower blades, which isn't easily seen. He put pressure gauges on the system at outside valves and reported coolant pressure was good. System was test run successfully. He sold us a 1 year maintenance agreement. 6/2/23 outside temp reaches 93 deg. We turned on the AC and only warm air came out. Outside compressor WOULD NOT RUN. We had Christian rep come out. He said all coolant had leaked out. He offered a leak test with dye for $510, or replace the "rusted" coil for at least $3681. We declined. A Christian salesman later quoted a full system replacement. We had another AC company investigate. He found the outside valves HAND TIGHT ONLY, which would allow coolant leak. We had him pressure test with nitrogen over a 4 day weekend, which he charged ONLY a $149 service call. Starting psi over 300. Psi after 4 days over 300 psi. We had him recharge the system. He noted that coils are rusty within 6 months from new. We then had him recharge the system. Total costs with labor & visits both companies $1,595. 7/11/23 Date writing this review. AC working well, same electric power usage for air temps as prior years. Christian seems more interested in selling new systems. Giving benefit of doubt, their 4/29 "technician" was incompetent."
