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. |
A good son that owns a highly popular website should probably buy his parents the Cadillac model as an anniversary present.
I know I would if in that position. |
I'd be real surprised if there was a way to cost effectively convert a condensing unit to 410.
If the current heat pump is less than 5 years old I'd probably lean towards just replacing the evap. If it's an older unit they may as well go ahead and bite the bullet for a 410 system. |
I think the lines and coils also have to be replaced.

One of the biggest issues is the placement of the air handler.. I honestly have no clue how they got it installed in the first place. It is huge and the the access is not. |
I'm not a specialist but I can tell you that almost every Engineering Organization I ever met who designed "White Goods" like A.C., Water Heater, Washer, Dryer etc. got input from their Sales/Marketing people and they usually make sure to keep older technology incompatible with newer tech unless of course they have an in house customer service unit where they will do less work for more margin thus creating a larger income stream for themselves. I'm guessing you have built in incompatibility.

I finally remembered I have a buddy who does this for a living in Austin who I have sent a message to. Hopefully he can set me straight. I have a sneaking feeling the costs will be about the same no matter on this. Interesting guy who has been doing this for years after retiring from profession bull riding. He even came back for a while and tried the "senior" circuit. |
Are we talking about a self-contained unit or a split system?

Inside coils have the leak. |
Replace the whole thing, a lot of money upfront but it will save you money in the long run.

This guy is great and he will provide second opinion if needed. http://www.bigbearair.com/

It's something like this (but not exactly) http://www.goodmanmfg.com/Residentia...8/Default.aspx My concern is the vast amount of labor required to replace the entire unit(I don't even see how it was put in in the first place) as compared to the POSSIBILITY of replacing just some of the guts (evap/coils). Of course, it may just be cheaper to buy the whole unit, I have no clue. |
