I live in Central Ky. Temps from 95-30. Would a heat pump only be a good way to go or a gas furnace? Here is what I came up with.
Would this be the best system for my money and performance?
-Infinity 16 Heat Pump (or should I go with a 15 or 18?Whats the best for my $)
-Infinity Series Variable Speed Fan Coil
-Infinity Air Purifier (Have Asthma & Allergies, do these work well?)
Just want some professional opinions, this is a big investment. The installer is very reputable and measured the outside of my home. Any other questions I should ask him? My home is 2500 sq and he said I needed a 4 ton unit. I have a 3 tom now and it runs all the time. Would this system last a long time? Also is the extended warranty worth it? Sorry for all of the questions just want to be sure.
