Our contractor has two Carrier units, both 3 ton.
– 2 stage 17 SEER
– 5 speed 19 SEER
The 19 SEER unit is about $1,300 more and I’m wondering how to quantify the value. There are at least two ways to look at it. Will the 19 SEER unit provide any benefits at all over the 17? Over what time period would the 19 SEER unit become cost neutral?
