Hoover's Home Energy is outstanding. We are 100% pleased with Hoover's work and customer service. We reached Hoover by phone with a real live answer on our first call, and we could always easily reach a live person any time that we called the company. Hoover's came out to give us an estimate quickly, as requested. The Napoleon furnace that they recommended is super fine. We checked Hoover's web site for all the selections before the estimate was done. We selected the Ultimate 9700 series furnace, which is a reasonable $800 more than the Napoleon 9600 series very high efficiency furnace, and which is even higher efficiency than the very high efficiency 9600 furnace. The Ultimate is a heavily built, 4 sided insulated, stainless steel/aluminum/titanium furnace with a lifetime warranty on the heat exchanger, 15 year furnace replacement on the heat exchanger warranty, a 10 year parts warranty on parts other than the heat exchanger, self-diagnostic indicators, uv light for removing bacteria, and a built-in convenient interior lighting system for inspecting the furnace. Hoover's installed this furnace on time. Hoover's also put in 2 exterior gas shut-off valves, and ran a line for an external generator to power the furnace in case of a power failure, at our request. We also like the 24 hour/7 days a week Hoover's telephone line and on-call service, if ever needed. We highly recommend this outstanding company. And, the service is very courteous and friendly. Plus, Hoover's performed a super good cleaning of our wood fireplace chimney.
