I have a Lennox Sentinel EC10Q4-25 electric heat furnace.

My home is a cottage (basement: 33' x 25', 1st floor 33' x 25', 2nd floor 33' x 25'

I need to replace my 3 ton (I think) heat pump (Lennox HP-23-411-1P).

I was told that the Lennox CVP10-46 (3.5 ton I think) coil inside the furnace also needs to be replaced because of the new 410 freon.

It was suggested by some air conditionig companies in my area that a 3 ton heat pump is too powerful for my home size and to instead go with a 2.5 ton heat pump (external unit) and a 3 or 3.5 ton coil inside my furnace.

What do you think about this suggestion and what do you suggest?

Thanks for your help
