Best thing to do is go with the best warranty and the best installer. Make sure they pull a permit and have the job inspected. I have a 80% Heil furnace in my home and have had no problems. In addition, make sure the installing company does a manual j load calculation and submits it to you. This will determine the size of the equipment in your home. Best wishes!
Now the freaks are on television, the freaks are in the movies. And its no longer the sideshow, its the whole show. The colorful circus and the clowns and the elephants, for all intents and purposes, are gone, and were dealing only with the freaks. - Jonathan Winters
