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

"We could not be happier with choosing Unique Indoor Comfort for our new HVAC system. We found this company by being referred by a client of my husbands. The original duct work in our house was extremely undersized, over working our unit and not creating good airflow to reach the third floor of our town home. Reni came out to our home, and took the time to explain to me options with Unique to really make our new HVAC unit/system efficient and comfortable temperatures in our house. I really appreciated his kindness and patience with me with all my questions. Unique was able to get us scheduled within a week or finalizing the contract, just in time in end of April when the first heat wave hit. It has been almost two months now since Henry and Matt installed our new HVAC system (they both were friendly and did an excellent job) and we are truly enjoying it. With a new baby in the house, it is a relief to have this new unit and ability to cool down our house quickly and efficiently. I know it is a lot interviewing and getting quotes from different HVAC companies - it is a big investment. This company truly stood out for us and were able to work with our budget and our needs for our home. They were the only company who proposed how we could add an additional vent to allow more airflow, and to redo the duct work to the proper sizing for our house and up to code. We are very grateful and HIGHLY recommend Unique. Thank you Reni, Matt and Henry again!"

"They were professional, and they did a very well job."

"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 had a very negative and unprofessional experience with Horizon Services. I signed a contract with them. When it was time to service my AC unit, they cancelled my appointment and rescheduled it, only to cancel and reschedule it again, and yet they did it again! They cancelled my AC maintenance appointment three times over nearly a month period. The scheduler kept cancelling the appointment a few minutes before the appointment time, which was very inconvenient for me because I had to be home every time they scheduled. After the third cancellation, I asked the scheduler to escalate the case to a supervisor which he told me he did. But the Horizon customer service manager never called me back. I called again and escalated again, still the Horizon customer service manager never called me back. I called at least twice after that and was told that my case was already escalated to a female manager, but still she never called me back. All I got from the Horizon phone operators was repeated empty promises that “someone will call you back in 12 hours, etc.” But they never called back to commit to either providing the AC maintenance service or cancelling my contract and refunding my money in full. What makes matters worse is that none of the Horizon Services phone operators who answered my repeated calls was able to transfer me to a manager to speak with in real time. These operators said that they could only “email the senior manager or the concern department”. What a disappointment, and what a lousy excuse to ignore a contracted customer. I truly regret hiring Horizon Service and signing a contract with them and I will never recommend them to anyone. The failure by Horizon Services to provide the AC maintenance per the contractual agreement (it’s now mid-summer and my aging AC unit was not serviced to date) and the fact that their customer service manager never bothered to respond to my repeated phone complaints speak volumes about the unprofessional way they have treated me."

"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! 🌟"
