    New heat pump system

    My Goodman 3.5 ton Heat pump has failed me and I have been getting estimates for a replacement. I have gotten 3 quotes in my town but none of them have offered to do a manual J. I have gotten same day quotes from all three, and although they were all recommended by people whose opinions I value, I am not sure why no one offered this. I think they think my main concern is cost, and although I don't have thousands of $$$ lying around, I want it done right and well and will finance it.
    Since my house is only 8 years old I've come to blame the install more than the equipment and question the original size choice. Should I be asking for the manual j heat calc or should reputable outfits be proactively offering them? I have followed up with one of them asking for it but haven't heard back from them yet (just reached out today). They are Trane dealers and I have been looking at the xr15 and xr16. I believe the Xr16 does not come in .5 increments or at least they are not offered by them.

    Most companies will not do a manual j until you sign a contract with them. I personally am not going to spend a couple extra hours doing a load calc for a job I'm not going to get. Good luck

    I don't do manual J on replacements, just new systems (new construction).

    If there is an issue with cooling, or heating I will count returns, and supplies, and see where I can add if needed.

    Sometimes there is nothing you can do
    The opinions expressed by me are not that of my employer.

    Thanks. I am having an energy audit performed through the electric company so that should shed some light on some efficiency issues. Almost ruled out some good techs I think. Since my unit no longer works, I have no idea if it short cycled. It struggled in the winter but a lot of heat pumps do around here.
