The Heating Specialist recently did some work for me. They came out to my home to replace the furnace. They are also putting in multi-zone thermostats throughout the house. Most of the work is completed and they are just now finishing up with the thermostats. I think the service itself has gone well with just a slight criticism. The young men who came out to the work have been very personable. However, they have messed up our rugs with mud. We have to do some rug cleaning and hope in the future they will be a little more careful. Otherwise, the work has been great so far.
