Good evening all...
I need some solid advice. I am in the process of requesting proposals to
replace my existing heat pump and air handler. I have proposals coming for:

Carrier - 38 ydb
York - ETS Stealth
Lennox - HPX19
Trane - XL19i

Each of these manufacturers have similar premium products. ie the
2-stage units.

What is a good, reliable, product ?? Is there a particular brand that I
should stay away from ?
