    New Heat Pump Estimate

    Hello all,

    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

    To clarify, I live in a three story town home. Also, not sure if a variable speed unit is necessary or makes a difference in this town home or if a single speed unit is sufficient.

    What is your location?

    Here is my personal checklist.

    Obviously correct sizing is important. If you are unsure, then request a
    load calculation or even perform it yourself for a nominal fee online.

    there are three equally important components-quality HVAC, the install by dealer, and probably the most overlooked and disregarded is the ductwork system.

    these are my minimum specs for a new HP system. both outside and
    inside units should be replaced to have a properly matched system.

    15 SEER, 12.5+ EER, 9 HSPF
    best matching VS air handler
    full BTUs in both cooling and heating for your rated size
    R-410a refrigerant(same as Puron)
    scroll compressor preferred
    electronic demand defrost preferred
    thermostat with "dehumidify on demand" feature
    staged backup heat strips
    new and correctly sized refrigerant line set

    you want a thorough inspection of your ductwork system. size, overall
    condition, supply and return lines, insulation qualities, leak test, etc.

    any hot/cold spot issues in your home should be addressed.

    I would look at Trane/AmStd,Rheem/Rudd,Carrier/Bryant.

    Depending on your location, I would not purchase a new HP system that
    did not have electronic demand defrost.

    IMO

    thank you for replying. i'm in maryland. sorry for posting the price, i now see that is something that should not be posted here, i apologize. i guess the bigger question deals with the unit itself.

    again, i appreciate your input and will look to find answers to those topics.
