which gas furnace is best
Trying to decide which new gas furnace and air conditioner to buy. Want to purchase a 2 stage variable speed furnace for a 4 level multi level home. Stuck between Trane, Carrier and York. Anyone have any comments as to which is better and whether to get R22 or R410 as refrigerant. Everyone gives me a different answer. Prices are around $7,500 to $8,000. Live in PA. Does that seem high?????
