"I was very happy with the job Green Sun has done and the communication they consistently provided. I met someone yesterday who was looking install Solar Panels and they mentioned how painful the sales presentation was (with a very high pressure approach). I told them I have had no issues with Green Sun and I have been very happy. Glen was very professional and informative in the presentation he gave. I also had a neighbor looking for Solar last year and tried to go with a competitor, but they kept delaying things with very inconsistent communication. The communication from both Glen and Chris was always consistent, keeping me in the loop all along the process as they pushed to finish my job before the end of 2020."

"I’m really happy I decided to go solar with this company. The team was professional, answered all my questions, and kept me updated throughout the entire process. The best part is that my electric bill is now $0! I honestly didn’t expect to see such a big difference so quickly. I would definitely recommend them to anyone thinking about getting solar panels."

"I originally reviewed Dawson Mechanical Contracting two years ago when this furnace was originally converted to gas. (Superbly.) I called them again this morning because the overflow tank was leaking water--today is a Saturday after a snowstorm--and Dave and his crew came out a few hours later and repaired the entire thing. (A serious and complicated job.) I'm grateful for the speed and professionalism Dawson Mechanical Contracting showed. My heat is working again, and the price was fair. I recommend these guys without reservation. Two thumbs up."

"Called for broken gas furnace. Came out and efficiently fixed the problem the same day. Would use again for repairs. They offered to deduct the price of the repair of a new system if we decided to change out the system since it is 18 years old. While the sales person was very nice and professional, he was a little pushy trying to sell us a system. Has called back numerous times. We ended up using somebody else who was offering a more efficient Lennox system (the brand Pipeworks was selling) for a few grand less."

"I had an issue with my stream boiler last Saturday. Did a google search and called multiple companies except Lighthouse (also part of Premier HVAC) picked up the phone right away and the tech Slava (unsure if I spelled his name correctly) showed up an hour after my call. He was very knowledgeable. He first did a thorough inspection on my streamer boiler (I thought mine was called furnace but he corrected me and luckily Lighthouse also repair stream boiler), then giving options (replace the water feeder and side glass or the whole stream boiler since mine was already past 30years and it may not last long). Due to budget issue, after discussed with my family, we chose for now just changed the parts. Slava has no problem with that and I got lucky that he was about to arrange time to have the work done the same day. Slava is also very patient and professional. As he learned that I am new to streamer boiler, while he was doing his work, at the same time, he was giving “a lecture “ in terms of names, functions of each parts and the concept of how the stream boiler works and how to maintain it properly. I gotta be honest that I don’t recall all the he mentioned but at least now I have a concept. In terms of the price, I can’t say that it’s cheap but you pay for the quality of service that you get. Slava literally taking his time and spent about 4 hours to repair. Highly recommend."
