"Phenomenal! The repairman, Sherrod, came and fixed the issue quickly and beyond professionally. I will definitely call Dilling Heating & Cooling again!"

"Excellent Service Excellent Customer Service Excellent Staff Recommend getting Service Contract!"

"I scheduled an appointment with them in response to their ad to flush a hot water tank for $49, no trip charge or add on expenses. After scheduling and in advance of the appointment I called for details regarding the service to be provided at this very hard to believe price. No matter what time of day I called I was always routed to an answering service that only scheduled appointments. Each time they said they would reach out to a manager to get my questions answered. After 3 calls and an email without a response, I cancelled my appointment."

"I wouldn’t be writing this Review if one thing would have happened, TALK TO ME. Don’t place the answering service in the position of telling a Customer that the Supervisor has left for the day at 2.45p on a Thursday. Especially when the Horizon repairman had just fried our whole cooling system, including the thermostat!! What started with a bad fan motor in a new AC system that was only 3.5 years old in a $10,000 system, for which we had waited 4 days for the new motor to be installed. Add to that the fact that the repairman told me he would be at our home at 8.30a and didn’t arrive until 11.30a - after having to use a vacation day to wait at home for them to arrive. Then telling me this will be ‘quick’ all I have to do is switch out the motor by mounting it and plugging in the new one. Hours went by, nothing. He comes in to test the thermostat and it is non-responsive. He tells me to get new batteries, which I did. Then asks me, “these are new?” To which I say, ‘of course’ - you watched me take them out of the box. Then he goes out to his truck for the next 1.5hrs, supposedly speaks with his Supervisor and comes in and tells me that he has fried the system. I reply by saying I will be calling a senior person to speak with them. Called 4 times and never spoke with anyone. Each time I waited on hold for an extended period of time. Each time, I was then told by the answering service that someone would call and never did. Then at 2.45p I am told “everyone has left for the day” and no one would be calling. This was a Thursday, I had been home all day and no one would speak with me. We remain without an AC system, no plan, no calls - - nothing!!! If I could rate them a ZERO, I would,"

"Very knowledgeable staff, on time, work done right. Great price and great product offered, can't ask for better! Will hire again."

"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! 🌟"

"Worst service I’ve ever have experienced. They wanted to sell me the product, never told me that there was an early termination fee and another penalty for an initial offer they gave me. Had double charges every month, once for the oil they provided (which they never told me they were going to provide before coming. They just came without my knowledge and then I find a high amount bill) and another for an “automatic payment” for 500 that they never could explain. The didn’t even fix this issue and it kept happening every month even after I cancelled the service. Then having to call them is a hastié for the refund of the 500. Stay away of this company"

"The screened-in covered porch attached to the back of my house had shown signs of leaking for awhile. This February, however, there were several storms that brought with them high winds and heavy rain. My porch?s small leaks became greater in number and magnitude.    Jim, from W.J.C. Construction Services, came over that same day and assessed the damage to the porch roof. He gave me quotes to either  1. just repair and replace the leaking  shingles, or 2. replace the entire porch roof. He explained the first choice would stop the leaks where they were visible, but that it might not correct the cause of the leaking. Choice #2 was to replace the entire roof.     I considered both options and chose to have him replace the entire roof. I am very glad I did. As he worked taking the old shingles off, he saw that the original roofing on the porch was not up to code. Had I chosen to have him just reshingle the original leaking ares, I would still be left with a roof that would leak again.    "

"He called back promptly, scheduled an appointment and showed up on time. This is, unfortunately, a rare thing with contractors these days. The price was very reasonable and his work ethic phenomenal. He went above what was quoted and stayed extra free of charge. Such a hard working and conscientious guy. Highly recommend!!!"

"I had an AC installed in July 2023. There is a coolant leak due to a valve that the installer admitted he had issues installing. I reached out the first week in May and the installer said it would be two weeks to get the part installed under warranty. He was apologetic and admitted fault. The company then strung me along for two months repeatedly telling me they would be out soon. Then they stopped answering and have ignored any calls and messages. It has been almost 3 months since I contacted them originally about the issue and they seem to not honor warranty coverage. "
