"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."

"We were made to sign a Waiver of Right to Cancel and an Emergency Work Authorization although I had made it clear on the phone that it was not an emergency, we were just replacing functioning older elements with new ones. He then gave us a price that, even though it was said to be a service partner rate (they had previously done HVAC work for us), seemed extremely high, but we didn't have anything to compare it to (a mistake), so we said okay and he began work. He appeared to be having trouble removing the old sink, but did not inform us that he was damaging our counter top in the process. Not until he was all done and waiting for someone to bring him the right color caulk did he show us the many cracks in our counter top. He seemed surprised that we were unhappy about the damage. He went out to his truck and called in, then returned to say that his manager offered to install a toilet we had wanted to have replaced later at no charge. That didn't seem like much consolation when we are going to have to get all new counter tops installed in our kitchen, plus the sink and garbage disposal taken out and reinstalled. Later we had another plumber install our toilet, which cost less than a third of the service partner rate originally quoted to us by the Horizon technician, with no damage. We did not want Horizon to do any more plumbing for us. In addition to the ruined counter top, when the caulk cured it pulled away from the gap, leaving holes around the back and sides. We were also surprised that he took everything with him without asking us. I told him that the old garbage disposal still worked, we were just replacing it so we wouldn't have to do it later, and would have tried to see if someone else could use it. The same with the unused pieces from the new faucet. We chose not to install the soap dispenser, and he left us the just the pump piece while taking away the straw, the bottle, and the rest of the assembly pieces, as well as the deck plate and gasket that we didn't use. Maybe technicians are told to scavenge spare parts for future jobs, but we had purchased everything ourselves so it does seem like we should have been asked, at least. I was not watching him when he packed up because I was still in shock about the counter damage and the prospect of now having to replace counter tops when we hadn't planned on it. I submitted a review to Horizon's website, but it never appeared there and I received no response."

"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! 🌟"

"Came over and took care on the spot. Well done"

"East Coast comfort did the most horrible thing to us, and they have treated us with utter contempt. We have been with East Coast Comfort since they began when Ed McCollum and Anthony Mongeluzi started the company in 2006. Both Ed and Anthony were to our home in the early years of their business, performing maintenance and repairs, and one of them was here when they installed our current unit. We gave them a favorable review on Angie’s List, and we have never had any complaints about them in almost 20 years, until Lisa Hawthorne. We schedule routing maintenance, so we do not have equipment failures and outages. We have repeatedly been asked by Ms. Hawthorne of East Coast Comfort to reschedule our maintenance appointments, and we have always acquiesced. This occurred again a few weeks ago, and we rescheduled for last week. Ms. Hawthorne again called the day before our scheduled maintenance appointment last week, asked again to change the appointment because of the volume of emergency calls they were receiving, and we agreed as long as Ms. Hawthorne promised we would be given priority scheduling if our system went down. The next day, our air conditioning failed, and I contacted Ms. Hawthorne. A technician came to our home on the afternoon of the next day, but he said parts had to be ordered, and it could be days before they would arrive. I have emails supporting that we requested Ms. Hawthorne to order the needed parts, and she emailed back that the parts would be $1500.00 and labor $500.00. Though we made it clear from our emails that we wanted to get the system repaired as quickly as possible, she did not order the parts and would not grant us priority scheduling. When we learned of this betrayal, we contacted William Henderson Heating, Cooling, Plumbing, and Electrical Services. They worked us into their schedule for same-day service. I have an email exchange that proves how disdainful Ms. Hawthorne was to longtime customers of East Coast Comfort, both of us senior citizens, and one with a cardiac condition. A request we made to Ms. Hawthorne to speak with Mr. McCollum or Mr. Mongeluzi was ignored. In other words, other people had their systems repaired because of our kindness, so we can swelter in the heat and humidity. I consider their behavior toward us to be elder abuse. Good riddance East Coast Comfort, we are now receiving our comfort from William Henderson."

"Great job strive!!!"

"Company is way to expensive and the work was not mediocre. They use GoodLeap for financing, and they rip you off with that contract as well. Stay away!"
