ive been reading alot about different people asking about different brands of furnaces, and it has really started to make me think
i always thought that most of the furnaces on the market are equally reliable, as long as you are comparing different brands equal furnaces, and the most important factor is how the furnace is actually installed, is that wrong?
are there other specs that change when you are moving up to a higher caliber furnace? besides big things like vs dc motor, 2 stage heating, corrosion free heat exchanger, insulated blower cabinet
i was also wondering what brands offer sealed burners, and if these are better (whether that be for noise or efficiency)
