I have had multiple contractor estimates and multiple opinions on what I need and what will work correctly in my home. I am now confused.
I am thinking of going with a new Rheem 80% 2 stage Variable speed furnace 3 or 4 ton 75000 BTU but I have a 2 Ton A/C condenser with a 2 1/2 ton. The Rheen furnace is apparently 17" wide and the A/C coil is 21". One contractor said they would have to replace the A/C coil with a 17" coil - another contractors said they would be able to make the 21" coil work and there would be no air flow loss or problems.
Which is correct and what ton size do I really need for my A/C to work without restriction?
I live in the Denver area so do I need to be sure the contractor uses a High Altitude conversion kit and adjust or replace the burner orifices?
Thank you for any help you can provide!
