    Advice on a new heat pump/new system

    It is time to replace my old heat pump as it issues not worth fixing.

    It appears I have a couple options so far:
    1. replace the heatpump(30 years old) with a goodman r-22 system with one that matches the somewhat newer air handler(15 years old).

    2. replace everything(getting bids right now).

    I would like to replace everything, however I may have to financially punt at this point and go with option 1.

    Any significant issues with option 1?

    Thanks

    A 15 year old air handler may be expected to last 2 more weeks or 6 more years.

    The existing air handler is not rated for R410A so you are limited to finding an R22 replacement outdoor unit. Since this is a heat pump, the odds of this untested matchup being a happy experience are not very good.

    I recommend a matched R410A system. Efficiency recommendation depends on climate. So where do you live?

    Mix matched heat pump can be lots of problems, and leave you using your emergency heat this winter.

    The system has been mismatched since I moved in 10 years and it has worked fairly well during that time. The air handler is a goodman and the installation company has verified with goodman that the two units will work together.

    Gosh,

    That statement should give OP/homeowner a nice warm fuzzy feeling.

    I get a reasonable warm fuzzy on that, but trying to factor everything in together. I am not sure I get a warm fuzzy on goodman itself or sticking with r-22 at this point.

    Still looking for what issues I can expect to have if I go with option 1. The inside unit is also a 4 ton, so it would have larger coils than the new 3.5 ton heat pump.

    If your outdoor heat pump has completely failed, and you are broke then I would consider option 1 as a mismatched heat pump is better than no heat pump. However.... a 15 year old goodman air handler? 15 year old goodman coil? Spend the bucks if you got em and go for a new system you will be MUCH better off in the long run.

    I was being facetious. I would take that statement with a grain of salt.

    Need Clarification from OP

    You say new R-22 "system"
    Are you saying new R-22 Condenser (outdoor) paired with new R-22 coil to be installed in existing air handler ... OR
    Are you saying just new R-22 Condenser with 15-year old coil in existing airhandler.

    If you are saying new Condenser and coil, could a pro answer how this is a "mis-match"????

    My AC coils started leaking after 15 years. Blower and furnace were still going strong. But I was fortunate to be able to purchase a complete new system. Your mileage may vary....
