We just had Kevin Shaw Plumbing install a new heating system in our home. They had promised us that the system they were installing would heat our house evenly both the upstairs and downstairs. They came through as promised. I can say, that after 2 weeks we are thrilled. With our old system, the upstairs would be 15 to 20 degrees hotter than downstairs. Now there is barely a 2 degrees difference. It is so nice to be able to walk around the house and have the temperature be comfortable all over. They said it would take two days and that is how long it took. I am looking forward to a cozy house this winter.
