I have had a very bad experience with Bill's Heating they installed a oversized house gas furnace in my mobile home it sticks out well out in the hallway. I cannot believe a company would do this. After discovering that a intertherm furnace is the proper furnance to be properly installed in my mobile home they admit that I should have been offered a intertherm furnance but they did not offer me anything they just installed the oversized house furnance and now are stonewalling me do not do business with this company RDI did my neighbors they did a great job
