Once 2nd stage satisfy the electric heat drops out then due to the compressor not running or system extremely low on charge and compressor is running not enough heat or no heat ( compressor off ) your blower fan always stays on as there is no heat to satisfy the thermostat.

    If the large copper tube had no heat whatsoever at the indoor or outdoor unit and are the same temperature as the small copper line again that would be a good indication your compressor has issues or extremely low on charge.
    Thanks again for the input. If you are on the right track, this is clearly not something I can fix. I've got a technician coming Wednesday... Hope the recent snow doesn't delay that. Auxiliary heat is working fine in the meantime.

    I added another paragraph to the above comment, try it and get the results all you need is a thermometer and the touchy freely thing of those lines also....

    Tech was here today. Said the evaporator coil is leaking. He could see refrigerant oil residue on and around the coil. Also said the standing pressure was less than 50 psig, whatever that means. He said almost all the refrigerant had leaked out.

    Said likely fix was replacing evaporator coil.

    For various reasons I'm probably just going to replace the system with a new one.

    Things to ask for from bidding Contractors, make sure the system is a match and has a active AHRI number. You can ask them for that number and check the SEER, EER, HSPF, total cooling BTU. If your paying for a 16 SEER system ( as an example only ) make sure that's what you get. Seen many times here homeowners where under the impression a unit that says 16 SEER ( as an example ) automatically gives them that figure on paper. Even matched system may give you 15 or 15.5 SEER on paper.

    https://www.ahridirectory.org/ Check here

    Proper check out and start up of the system is very important, static pressure, correct field refrigerant charge, checking defrost operation, correctly sized sealed ductwork etc. etc.

    Some brand models heat pumps require the final adjustment charge to be done in the spring/summer time or whenever the OD temperature is somewhere around 60 degree or higher and a warm indoor room temperature and in COOL mode. If that is the case ( install guide will say ) they need to set up a appointment with you in the future. They can field charge and get the charge close in the winter heat mode but would need to come back and charge in cool mode.

    Research if your local gas utility company or state has rebates for installing energy star rated equipment.

    Make sure your system gets registered.

    Make sure you get several bids from different Contractors

    Did he show you or take a photo of the oil residue on the coil and show you?, did he put soap suds on that area and show you or take a picture of the leak and show you?

    It's an R-410 system. Outdoor temp was mid 30s or so.

    Thanks for the advice. He did not show a photo or otherwise prove the leak, but his advice is consistent with how the heat pump has been acting. In hindsight I suppose I should have asked, but the guy seemed trustworthy. Oh well.
