We were adding forced air and heating to our older house, which was not entirely straightforward. Bob Gnoth understood what we wanted to do, advised against a more expensive plan, and followed through on our agreed upon strategy perfectly. The price was slightly lower than other quotes and we have had absolutely no problem with the new compressor, furnace, or duct work. He worked very quickly and was very responsive. I have no qualms highly recommending Gnoth and Naragon.
