Great company to deal with. Cheapest of 3 quotes for hi-efficiency furnace. No upselling. Work is very well organized, workers are clean and professional. Best quality furnace for cheaper price (of 3). Kevin, salesman, also assists on installation. Very knowledgeable, friendly and efficient. I trust these guys! I would recommend highly; will use them again when a/c packs it in.
After 4 days of no heat, GNA was here the next day with furnace, truck and crew. Put down carpet protectors first thing. 4 hours later, we had heat; furnace very professionally installed.
Met Gus initially on repair call for Sears. Thank goodness Sears is no longer in the business; they were awful. Gus didn't try to sell me a new furnace or a/c though he could have. A great company...you can't go wrong.
