We have lived in this tri-level house since it was built in 1975. At NO time through the fall of 2012 has the distribution of either heat or cooling air been uniform. A most uncomfortable difference between the first and third levels was there during the hot and cold seasons. Luckily, for us the furnace sprung a leak in the fall of 2012 and Guin quickly responded. They, put in a a Bryant Evolution Zone control AND it has worked LIKE A CHARM!

Each level is set at a different temp and is maintained there constantly including our finished basement. Best of all, our heating bills(natural gas) have cut by 60%.

Melvin and BG just left my house after heroic work on my sewer line. Besides repairing whatever wasn’t working and leaving everything neat when they drove off, they were unfailingly patient with my curiosity about the work and my various comments and questions, even though they no doubt could have worked much faster without my interruptions. Guin has been taking care of my house for a loooong time, and I am inexpressibly grateful to all of you for making so much of my home run smoothly.

Thank you for allowing me to lean on you all these years. As you no doubt intended, my life has been easier and more joyful because of your support.

Richard McDonald and Chris arrived on schedule, were very cordial and went about their work in an efficient manner. As has been my experience for many years, dealing with Guin and all of their personnel is always pleasant and results in a job well done. Pricing is always fair. You can’t go wrong with these folks.

Initially talked to Ricky about replacing 2 GE systems. Cole M did the installation and now my family is enjoying a climate controlled environment. We were quoted a great price, the installation was quick and the guys cleaned up behind themselves. I will recommend Guin to my family and friends without reservation.

Have used Guin for many years and have always been pleased with the services they provide. Gary serviced our Heating system and also our Generac Home generator today. He was very thorough testing and changing out filters and advising us of things to watch out for which might need serviced in the near future. Gary R. Is very trust worthy and personable. I highly recommend using Guin for all the services they provide like HVAC, Generator installation and service, and also Plumbing.
