Project: Repair Natural Gas or Propane Furnace / Forced Air Heating System
We had a sweet smell in our house when we came home from work one evening, and potentially this could be a furnace problem. So, I called and spoke to a supervisor, and he talked me through it, and during the conversation, I decided to have them service both of our hvac units when they came the next day. They were professional, honest, and did what they said they would do. This is appreciated because so few people do this anymore! Thank you!
Response by Sullivan Service Co.: Thanks for giving us opportunity

Review by in Kimberly, AL
Sullivan Service Co. was the first HVAC company that reached out to me as soon as I starting looking on Home Advisor and Angie List. I was looking for a contractor that can and has installed (Mini Split Units) heat pumps, which I needed for an in-law-apartment. The owner of Sullivan actually was the one that contacted me by phone and listened to what I was looking for and told me that they would be happy to help with my project. I did tell him that I needed to get some more contractors to also look at what I needed and to give me information on different brands and prices. Of course, I had a few smaller contractors and three of the larger ones out of the Birmingham area. The prices and brands ranged from the top of the line to the bottom (cost-cutter), I am a firm believer in you get what you pay for. After reviewing my options and discussing this with my better half, we decided to go with the very good and well know the brand that Sullivan Services could provide and the price was very good. As soon as we pulled the trigger on this project Sullivan Services were on top of all the details and the installer (Daniel) was out looking over what we needed to do. Within a week and a half, we had a 1.5 ton 18,000 btu mini split heat pump in our basement. Sullivan Services also had to set up another contractor to drill a 2-inch hole in my foundation for the lines to go outside. To put this all into perspective the quality and the value that I received from Sullivan Services is top-notch and I do not feel that you could find a better HVAC contractor. I am also planning on using Sullivan Services to service my two other heat pumps next spring. Thanks, Gary, Kimberly, Alabama

Everyone from this company was professional from top to bottom. From the the tech who came and inspected everything to the installers to the owner. They came on time, they did not make a mess, they told the truth about their products and did not try to over sell anything. I would highly recommend them. I apologize for writing my review so late.
