Endless Energy staff are accommodating and professional. Alycia, in the office, patiently answered my questions. Dan, who did the initial audit, was thorough and clearly helped me understand my options. Ryan, who supervised installation of the splits, kept me informed about modifications required due to unusual structure of my house's frame. Seth changed the water heater installation to accommodate my request that it be elevated off the floor. Brian, the carpenter, did an excellent job of matching a wall which had to be built to fill in a large gap where an old radiator was removed in my kitchen. When he returned (to repair a hole in my ceiling, inadvertently caused during insulation work) I knew he'd do another great job (which he did). My entire project began on May 13 with an audit, and has taken months but I'm very satisfied with the high quality of the workmanship and the very accommodating staff, every step of the way.
