Karlo is the best! Today he serviced our furnace after we experienced soot in our basement. Not only did he diagnose the problem as our oil tank, he made sure a Burkholder consultant came to confirm the need for tank replacement, provide a quote and schedule the replacement within a week. He also provided the name of a chimney sweep, who was scheduled of the next day. Not only does Karlo know the technical side of his job, he goes out of his way to make sure the client knows what needs to be done and assists in getting it done.
