Any home heating and cooling techs here? - 01/28/20 09:16 PM
I need some tech input on a new furnance and ac unit for the house. I had two different companies come out and give me a quote for replacement equipment. I currently have a 100,000 btu furnance and 5 ton ac unit. The house is a two story 3,000 square ft home. One company said I need a 110,000btu furnance and 5 ton ac unit, the other guy said I need a 90,000btu furnance and 2.5 ton ac. He said to go with smaller furnance because my 100,000 unit is short cycling, because it is too big for the house. He also said it is more efficient to go smaller with the ac unit and have it run longer for more even cooling between the upstairs and downstairs. There is a $2,500 cost difference between the quotes. What is the correct size units for my home? Confused after talking to these contractors. Please clear things up for me. What's more cost effective for fuel and electricity? Thanks
