Hello everyone. I am currently looking to install a brand new heat pump system. My square footage on in my attached townhouse is roughly 1100 above grade and 30 yrs old with mediocre insulation (original doors and sliding glass door) and i am currently running a 2.5 ton 10 seer system. My neighbors are running a 2 ton system as well as my gf and all claim to have quiet systems and they are comfortable. My unit is very loud and the air seems to be blasting out of my vents which can be loud and annoying. My current unit also does not seem to be very efficient.
I am currently torn between an Amana ASZ14 2.5 ton 15 seer single stage system with a variable handler and a Frigidaire 16 seer 2 ton dual stage stage system. The contractor looking to install the 16 seer says the 2 ton dual stage is plenty while the person wanting to install the Amana says that the 2.5 is good with the variable handler, especially when temperatures become extremely cold, which is why it was upped to a 2.5 ton from a 2 ton. I am torn between the two systems and am not sure which way to go. Should i consider stepping up to the 2 stage dual stage system? Any feedback would be greatly appreciated.
