We asked Wojo's Heating & Air Conditioning for their opinion and pricing, because there was an issue with the furnace that didn't seem to be working right. Their professionalism was fine on the phone, and he gave information about the costs upfront. The difference was about $40 for service on the weekend--to just come out and investigate and figure it out. They gave the advice of resetting it, but that didn't seem to resolve the issue right away. The issue did resolve itself, so we didn't need to use them. I didn't have any issues with Wojo's and I would probably tell others we had used them--and that it was good service--if it came up in conversation.
