I am currently shopping for a new furnace and got four estimates. I have a 2000 square foot 2 story home with a full basement which is 1/2 finished. The 2000 does not include the basement. The home is 15 yrs old and is insulated and sealed pretty good.
Here is my dilema. I am look for a 2 stage 90% + efficient furnace. My current furnace shows a BTU of 115,000. Two estimates came in with 100,000 BTU, one 80,000 BTU and another 70,000 BTU. The guy who quoted the 70,000 said the current furnace is too big, short cycling, and everyone is going off the current furnace size. I have seen the furnace turn on and off a few times within a few minutes but not all the time. I mentioned this to one guy who quoted me for the 100,000 and he said that the size of my house requires a 100,000.
Can anyone help me in determining which is the best furnace for my home?
Thanks for any advice you can provide.
