Just joined the Home Owners Protection Plan (HPP) that Efficiency offers. Had my first Fall preventative maintenance done on my water heater and furnace as part of the program. Technician, Tim, provided me a lot of very good information and the work was done to my complete satisfaction. Saved considerable money on my furnace filter as part of the HPP. Dealing with the service coordinator, Shaunna, is a pleasure and helpful. I certainly recommend this company and the HPP.
