new coil or new compressor or both?

That is sound advice. The reasoning is logical. So why are you here? You know damned well its the wifes OK you have to get.

yeh another ripoff! get nother contractor who wants to work

It's 15 years old but works just fine.

:-)

But make damn sure they have a brain, unlike newjersey.

It wont hurt a 410 rated coil if you run r22 in it but if you later change refrigerant over to 410 it will need to be thoroughly flushed which adds to the materials and labor cost.

It's not worth the extra cost to flush a coil later. Besides the TXV will have to be changed. Why not change the system now and save money? That's the smart way to do things. But hey, it's *their* money!

Replace the entire system and be done with it.

Basically what I said.

what make you think that there is TXV on the system

No no go to KJPRO he will deffinatly do nice job on your valet

There has to be a TXV on the system, they don't make evap coils without them anymore.... but then you don't do resi HVAC do you. Maybe if you did a little homework??

anymore....but this unit is few years old

but then you don't do resi HVAC do you. Maybe if you did a

And we're talking about a *new* replacement coil... Jeez... you must be stuck on stupid.

Do it right or don't do it....

I suppose now you are going to tell us that copper is rated for 410

Man question was will it hurt 410 rated coil if use on R-22

Simple answer Is NO! However to get proper rated capacity

That could be a problem and that is Evaporator versa Condenser

or Condenser versa Evaporator.

And I do not believe that they can not get original replacement coil

Instead giving him a fast one.

And KJPRO if you don't like my answers TS have nice day TONY

Tony, finding a 10SEER evap coil is almost impossible now... Even the 10 SEER trailer coils have to be special ordered.....all your gonna find on the shelf now is 13+SEER with expansion valves.

You don't have much of a choice now. As far as running R-22 in an R-410a coil, thats not recommended at all.... nor is it cost effective, unless you don't warranty your work. The capacities and expansion valves are not even a close match.

If you want to frankenstein a system, then do it with *YOUR* customers, as for myself, I am gonna do it right, or I am not gonna do it.

BTW... cryo, and commercial refrigeration systems are a far cry from the new resi equipment, and there is no comparison. You stick to what you know best, and those of us who do resi will stick to what we know best.

It's not that you *try* to answer questions, its that your answers are

I wasn't going to get into this because it sounds like you're getting good advice to change both units but there is an alternative. I'm at the beach & its very common to change the condenser only because of coil corrosion since the air handler will outlast two or three of them. It's not uncommon to find a reasonably new condenser with a bad air handler coil that needs replaced. Goodman & Amana use the same Air Handler/coil for both their 13 SEER R22 & R410A units. I haven't had to convert one to 410A yet but there is an ARI match for them. So for people eking by & trying to save it is an option though with a 15 year old condenser I would not recommend it.
