Question 1:
What would be the seer of the following (existing central A/C heating unit)
HS14-511U-6P / C819-51-1P (TRANE)
My goal is to get a unit set that cools as well as the current unit - but with more energy efficiency and possibly better humidity control. Also - the current unit is older (I believe). I think it might be from 07/89 - at least that is what a sticker on the side says... so I'm thinking that means July 1989. It still works but has twice frozen up on us in the last month and seems to function erratically.
I am being offerred numerous options from a local vendor. Price is less relevant to me as they all fall within 1.5 k of each other (i.e. not discussing price).
If I drop the lowest two price points (and lowest SEER Ratings) then I'm left with:
Rheem RANL0601AZ/RHLLHM6024 - 15.8 SEER Puron
Trane 4ttx6060B1000A/4tEE3f651000A - - 15.1 SEER - Puron
Trane 2ttR4060A1000A/TWE065E12FB - 14.8 SEER - Freon
(I believe the 4ttx6060 should read 4ttx4060 - but that how its listed on his proposal).
Also - the older unit is 4 ton and the new one is 5 ton... reason being - we've added 2 sets of glass double doors and a 200 sq. foot addition to the house that has all glass walls n one side - hence more umph needed (i'm guessing at this - its what the vendor told me).
Or is there a combination not yet offerred that provides better cooling at lower operating cost - but is perhaps freon?
