Customer Question

Like the people above, I'm trying to decide what unit to purchase. I have 2 companies that are quoting me Trane and one company is quoting Daikin. The lowest cost for variable speed condenser and air handler, 5 ton, 18 seer is 11,800 (Trane unit). The 2 stage condenser with variable speed air handler, 5 ton, 16 seer is $9,300 (Daikin) and $10,400 (Trane). Do I need a variable speed, 18 seer? I live in Phoenix, AZ and right now I have a 5 ton, 13 speed, single stage condenser and just wanted more efficiency and lower monthly bills. Any help you can give with this decision would be helpful. I need to make this decision in the next day! Thank you!

The variable speed will definitely be quieter and more efficient. As for SEER ratings you can figure you will save about 10% on utility bill per SEER rating. So if you had a 200 dollar a month electric bill for ac with the 13SEER, your bill would drop to about 140 with the 16 SEER and to about 100 a month with the 18SEER.

My preference would efinitely be the Trane and as you can see, will pay the difference in a relatively short time

I think Daikin is offering complete 12 year parts where Trane offers 12 on compressor and 10 on the other parts, my preference is still the Trane.
