Recently my AC unit has crashed and it appears I need a new unit (heat pump). MY wife is pregnant (35 weeks) and getting AC back is pretty damn important to her (obviously) at this point.
I've been given an estimate for a 2 ton Amana heat pump system with a ASV14 outdoor unit and an AVPTC1830 variable speed air handler unit for my townhome. The unit will produce 15 seer, 12.5 eer, 8.5 hspf according to the estimate.
My questions are:
1. is this a good unit? I've read many online reviews crushing the Amana brand and claiming how often it fails and how loud it is.
2. is a price of $$$$$ reasonable for the installation of this unit.
3. I understand that the new more efficient units call for wider "lines" if you will. My lines are currently 5/8 inch thick and the new lines should be 3/4 inches? is that correct? can the unit run effectively with the 5/8 inch lines or should i install the 3/4 inch thick ones?
I greatly appreciate your time in taking to answer these questions and advise me on the subject
