I have read through several posts in the last several days to get educated on our purchase. Thank you to all for sharing information. I have narrowed my choice down to two units whose dealers both performed J tests for me to properly size the unit and both sized it at 3 TON. One of them gave me the numbers to verify. I believe both will do a fine job with the installation, which I understand is the most important part.
The specifics are as follows:
Trane unit -- Trane XL20i (18.5 SEER, 9.0 HSPF, I am not sure what the EER is on this unit) with CleanEffects (to reduce dust due to allergies). Unit would be the 4TEE3C04 Air Handler with the 4TWZ0036 heat pump and the Honeywell 900 controller.
Amana unit -- ASZ18-036 heat pump (18 SEER, 13 EER, 9.5 HSPF) and AEPF3137 Air Handler. I am inquiring about the control system for this as the quote just says digital display heating and cooling thermostat. Prefer the Honeywell 900 based upon what I have read.
I read seveal articles about the CleanEffects unit and it appears there were issues up front and a recall, but that most appreciate the reduction in dust. My wife and me are both allergic to dust and our house gets dusty quickly with our current unit even though I use the higher end 3M filters and replace them monthly.
I will get the extended warranty for labor on both units. The Amana unit will end up being about $700 cheaper overall.
My pros and cons are as follows:
Pros - Excellent unit. Many satisfied customers. Good warranty (12 years on compressor). Two compressors. $1,000 discount. $1,500 tax credit. CleanEffects.
Cons - More costly than the Amana. Concerns about CleanEffects historical issues.
Pros - Excellent unit. Many satisfied customers, Excellent warranty. Cheaper than the Trane.
Cons - Dealer about 20 miles away, so concerned about service if necessary. I read that even though the outside unit is under warranty that you would have to replace the inside unit to make sure they match, so there would still be cost.
I would appreciate any comments or recommendations that would help move me in one direction or another.
