"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."

"Professional. Efficient. Got right to task and 30 minutes later he was done. Already recommended him to a friend."

"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! 🌟"

"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."

"They truly live by the code of "you get what you paid for". The price was cheaper than expected (and they included a free estimate too). So ultimately, our slow bathtub drain was cleared. However, the technician had terrible housekeeping. After stripping the caulking around the overflow valve, they left the caulking pieces in the bathtub and told us to flush them down the drain (?!). They said the provided bio solution would clear the pieces just fine...but why do that when a trash can is less than a foot away?? Then, they did not offer to reseal the valve they just opened...just left a mess for us to pick up. As such, we will not be using them again next time...free estimate or not. If we wanted the bare minimum, we would have done it ourselves."
