    I do not have a Goodman. I have a Payne (basically a lower-end Carrier). United Air Temp can install other brands besides Goodman and Amana.

I have received a number of complaints from homeowners with the frequent defrost cycling and really try to avoid using heat pumps for this reason.
    Not a problem.

    Second Opinion, do you live and work in the D.C. area by chance? You seem to have the ability to comment about equipment and contractors in this area.

    I had the impression that this area is heavy with Bryant/Carrier dealers and advocates.Or is just a quirk of the ones that I sampled? I used some recommendations and the lists from Checkbook.org.

    Just a quirk. There is plenty of all brands. I happen to know quite a lot of them. You have all of the 5 major brands Trane, Carrier, Lennox, Rheem, York.

    do you have personal preferences, ranked, and reasons why? how about pricing? I heard that Goodman's tend to be cheap and Trane tends to be expensive.

    There is a variety of heat pumps in my neighborhood with a lot Carrier or Bryant. Second Opinion, do you think you could tell me the company you work for (by email if necessary)? I'd really be curious to know which one; chances are I've heard of them.

    Non-expert you are correct that Goodman products tend to be cheap and Trane products tend to be expensive. Although I like Trane products, I don't mind Carrier/Bryant, Rheem, York, etc. From what we discussed via email, it sounded like you had a good contractor. If you're still looking for a contractor, I'd still recommend the ones I sent to you via email.

    Use a heat pump with on demand defrost. Instead of time and temp.

    Does that mean the homeowner chooses when he/she would like the defrost sequence to begin?

    No. The board monitors the OD temp, and the temp of the coil, and how long since the last defrost to determine if a defrost is needed.
    After the OD temp drops so low(varies by manufacturer), they won't go into defrost more then once every 6 hours.
    Saves a lot of electric not having needless defrost cycles.
