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

"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."

"Service was excellent. Technician was courteous, professional and thorough. He explained everything."

"Crew was professional and they did a great job."

"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,"

"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! 🌟"

"Repair Service to Fix Gas Boiler - WM Henderson first sends out a tech who is not familiar with gas boilers and admits there is an issue but does not know how to diagnose it. I had to pay $89 for this. Instead of having the right person come out, I had to to actively call again to get someone else to come out. The 2nd tech diagnosed the issue, but wants to charge me the same $89 that I already paid. - and quotes me $380 for the repair - and has to order the part. I agree and then call back the next day to confirm part is on order - and they tell me the charge is $1,015. I asked to speak to a manager to discuss, and no one is available and no one calls me back. I bought the replacement part from a supply where house (confirming it works with my make/model of boiler) and it cost me $165. I have had other scheduling issues with them as well. Don't use them!!!!!!!!"

"On 4/6/2018 a representative from Generation Electric came to my home to provide an estimate to replace an existing chandelier with a replacement of the same chandelier. The existing chandelier was being replaced due to the previous installation errors and damage sustained during the first installation attempt by another electrician. I made the representative aware of some very important aspects of the installation at this time. The chandelier has 22 crystals and would need the cords cut to equal lengths and rewired. Each crystal would need to be wrapped to insure that they would not bang against each other and become nicked. The entire fixture is very heavy and four people minimum would be needed onsite to install. The representative assured me none of these concerns would be an issue and that electricians experienced with installing similar fixtures would be sent for the install. I explicitly told him that this was a job for professionals experienced with this type of project and that I did not want a repeat the first attempt- the chandelier was expensive! On 4/24/2018 a crew of four electricians arrived to install the replacement chandelier. The first step was the removal of the old chandelier. After this was complete the electricians informed me that they did not feel comfortable or believe it was safe to install the new chandelier without additional support beams being installed in the ceiling. I agreed and told them I would have the ceiling cut open, supports installed, drywall replaced and everything repainted for the installation. I had this work completed over the next couple of weeks. On 5/11/2018 the second crew of electricians (only three this time) came to my home for the installation. The window of arrival was 8am to 10am with a call prior. I received no call and they arrived at 9:10am. After a few minutes of being there and me telling them protecting the crystals from nicks was top priority they determined they needed something to wrap each crystal with. Shouldn’t they have known this? One of the electricians was from the first crew additionally, this was made quite clear during the estimate. At this point two of the three guys left to go to Home Depot to buy bubble wrap. Approximately an hour later they returned with bubble wrap and began the installation. The team struggled from the very beginning from how to best move the fixture out of the box to work on the wiring to where to place the fixture to get the cord height adjustment taken care of. I told them that the previous team elevated the fixture across two four feet ladders which helped with being able to adjust the cords and wire the fixture. Once the wiring began one of the electricians told me that they would not be able to make sure each of the crystals were level and that the fixture was not meant to be rewired or have the cords cut to length. This was incredibly infuriating to me! I gave complete instructions to the estimator and hired your organization to complete an install that now I was being told could not be completed the way it was meant and agreed upon. Restoration Hardware indicates directly on their website that “cords can be cut to length at time of professional installation.” Isn’t that why I hired your organization?? I told the electricians this and one began to actually get aggressive and loud with me. It was to the point where they were saying they did not think they would be able to complete the job. At this time I had no other choice but to stop working (I work from home) and begin to assist in the process. I instructed them and assisted for the next two hours. I could hardly believe this was happening but wanted to get the fixture up and was done hearing them ***** about the fact that it was a difficult/impossible job and they only had three guys! I also called your office at this point to request a fourth person. I was told someone would look into it and call me back. I never received a return call. Apparently there was some communication with the electricians as they mentioned the field supervisor was not responding and was probably in a bar?!? During the process of me and one of the electricians trying to level and secure each cord- which by the way several crystals still are not even close to being level because the ladders were not level with each other- one of the other electricians went to get smoothies and one stood watching. After that part of the installation was complete the electrician that assisted me left for at least an hour- I think he went to sit in the van? The chandelier did finally make it up to the ceiling but is not flush to the ceiling all the way around- it was too heavy to do this with three guys which is why four was requested during the estimate. During the clean-up of all the trash, wires etc which piled up along the way one of the guys ran right into the crystals (now uncovered) with his head and banged several together resulting in chips in two of them. Unbelievable- this was the main reason the first fixture was being replaced! Needless to say this installation was NOT a success! It was made very clear during the estimate that individuals with experience installing this type of fixture should be sent- this did not happened and now I again have a 5k fixture that is damaged and not installed correctly! I am completely disappointed and feel like the estimator sold me a bill of goods!"
