I've used Shannon Heating and Cooling a few times. They have been pretty decent for the most part. Their communication... could be a little better but the reason I'm leaving this review if because of the following. I have an Airbnb in town and I received word from my guest that the heat stopped working and they made other arrangements for the next evening. I called Shannon heating & cooling. Once they got there my cleaning lady told them a door that had been left open and she believed that was the reason the heat was keeping up. They stayed 15 minutes to monitor and then let me know. I told them to send the bill. I was expecting $75 as that's usually a standard service call fee and I think for 15 minutes of just waiting isn't bad. They ended up charging me $150 for that 15 minutes and when I called to ask about it they said it is what it is. I've decided based on this I'm no longer using them in the future and I would advise if you are in the market you shop around.Update: The owner called me and said due to the short time he would reduce the bill to $75 but in the future to know that all service calls are $150 more

Our heating system went on the fritz and they updated our air conditioning unit at the same time. The process was quick... and efficient!read more

Called for them to come out because my AC quit working overnight. While he was checking it out it started working. I... asked what he did to get it started. He said “ nothing, it just started “. He checked the Freon and nothing more and left. A $150.00 service call. The next night it happened again. I called and asked if they could send someone more knowledgeable out and because they didn’t fix it the first time if they could waive the service fee. Boy did I get an ear full. So every time they come out it is a $150.00 whether they fix it or not. Update: So in the end I educated myself, did my own diagnostic and testing, discovered the part I needed, ordered it and replaced it myself. And all I got from Shannon was charged $150.00 for more

I called Shannon Heating & Cooling on Saturday of Memorial weekend not expecting a real person to answer, but to leave... a message hoping to request service for Tuesday when they opened. My furnace was not working. To my surprise, the phone was answered by a real person and I believe it was the owner! I explained the problem and he told me a technician would call me shortly. 90 minutes later the tech and called me, been here and had the furnace working. In a time when customer service is almost nonexistent, I cannot express my amazement at how this company operates and takes care of their customers. Very rare!! I am so appreciative. Wonderful people to deal with!! Thank you!! I highly recommend them for your heating and cooling needs!read more

On Sunday 2/14/21 in the early morning hours when temps were well into the negatives and we were getting half a foot of... snow our furnace died. We called, they came out to our rural home quickly, and assessed the situation. Monday morning they went to Springfield to get a new furnace for us while other members of their crew removed our old one. By 430 in the afternoon Monday we had heat again. They were all professional, knowledgeable, and exceptional. We couldn’t be more pleased and highly recommend this company for coming to our rescue and not charging an arm and a leg for it!read more
