Hi, Experts, Is there a sure difference between this two? At last got hold of a real experienced, knowlegeable installer who started with Manual J calculation.
My choice of our new furnace is 2 stage, variable speed blower model. He gave a choice of comparable York, Carrier and Bryant. Any advices? Installer says any one of this 3 is a good choice. I am still shy on modulating type for reliability concern. York will need little more sheet metal work to fit. I'll have to decide by next week. Thanks,
