I was told by a competitor that my dual wall heater needed to be replaced and turned off the pilot. Another technician arrived to try and sell me on ductless mini splits as an option (I do not have A/C). I opted to get a 2nd opinion and quotes for both options with Bill Howe. Alvin surveyed the house and offered several options of split placements in master bedroom and living room. He proceeded to check on the wall heater and ended up doing a complete servicing! No problem was found and stated it was in good working order. Relieved, I still have heat and can take my time to consider a Bill Howe ductless system. Bravo for Alvin!!!
