I consulted Max Heating two years ago due to uneven heat distribution in my home. I was advised that my two old Lennox furnaces should be replaced with one new efficient furnace by a brand I did not recognize (that should have been my first clue). As a result, the uneven heat distribution got WORSE!! When I complained, I was told by Dave that it was my fault for choosing to replace two furnaces with one. Stay away from this company -- at the front end reception service seems nice, but the boss and the technicians, the people responsible for the job, not only do not solve the issue you asked them to solve *they make it worse* . . . and then blame you.
