“I can’t say enough good things about the quality of service and comparative costs for those services. Bagniefski provided the best estimate for a high efficiency boiler system. The installation was done in less than a day. The furnace room never looked better with the boiler installed on the wall, replacing one that took up space on the floor. This past heating season was the most comfortable and economical in 52 years. In addition, I received two sizable rebates for choosing a high efficiency unit! I highly recommend you choose Bagniefski for reliable, honest, friendly service.”

“Shortly after purchasing our home, Tim’s team replaced an aging and inefficient hot water boiler and water heater with a new high efficiency condensing boiler and indirect fired water heater. His technicians were well-organized, efficient and the team lead was very knowledgeable about how to configure the advanced technology that controls these units for our home. We recently turned to Tim again to consult and help us sort through options when converting a sun porch to a four season room. His questions, research and recommendations helped us pick just the right solution for our application.”
