We called a couple of places to get estimates, it wasn't going to be an easy or inexpensive job, Tim at Day asked what we had, asked for some pictures with some fact finding, same day I had the estimate. The others we asked for quotes didn't even get back to us. They scheduled it to be done in less than a week. The techs that serviced our issue kept me in the loop every step of the way. Day may not be the cheapest but there's a reason for that, in this case you get what you pay for. We've always had good luck with them and they've always been patient with us.

This was my first encounter & from Rep to serviceman no one could have been friendlier or more efficient. Even their billing process went smoothly. With rising costs I felt their charges were fair as well. Couldn't be happier & definitely will be calling them in the future when needed. Service: Heating maintenance
