We just bought a new house, and we were already having issues with the heating system. A family member who lives nearby recommended Flanders Heating & Air Conditioning and we decided to go with them. They came out several times to try and fix the issues we were having and kept coming out because, when it seems they had discovered and fixed the issue, something else would come up. They stuck with it though, and now it seems to be working without a hiccup. We really appreciate their persistence in getting the problem resolved. They were friendly, and the staff who coordinated the visits were on top of everything, always answered our phone calls, and were just very helpful. We now have a service agreement with Flanders, so we will definitely be using them again.
