Any HVAC experts want to weigh in on something...

My parents in DFW have an old system that it appears the evap/coils on the air handler are shot. It's an R22 system and they are trying to see if it is worth upgrading to r410 now. My question is... could they replace the evap/coils on the air handler and then also just replace the condenser on the heat pump and get away with a cheapish conversion to r410 or will they need to run new lines and replace the whole air handler and heat pump.

The other option is to just replace the evap/coils and stay R22 but that seems like a pretty big expense to not just go ahead and upgrade things.

If it is a Goodman unit replace the whole thing. Goodman products are the absolute bottom of the barrel.

goodman is not the bottom of the barrel, a quality install means alot. for some reason alot of hack jobs used goodmans. of course it's not the same as a train or lennox or maybe a york. but you need to go premium on those, they do make entry level stuff that goodman is as good as. they also brand some units with other names that are just plain cheap.

i recently discovered this DIY product that seals minor leaks, i may give it a try soon. feedback on some pro boards seems pretty decent.
