New Condenser Proposal

I received this as a replacement for my old AC condenser unit I've created past posts about. Does it look legit or worthwhile? The guy's charging $500 labor on top of the costs.

Thanks!

 

Why would you put an R-407C unit in? And keep an old evaporator coil.
A better investment would be a matched R-410A system.

 

I don't know your back and forth with the company responsible with this invoice but it seems odd. I'm in agreement with "roughneck77" and would think a HVAC company wound recommend a R-410a system as well. It also seems odd that they would list a pre-charged R-407c condenser right after listing a 25 lb jug of refrigerant, -did you ask for extra refrigerant on the side?-

 

I'm not entirely sure what answer to give. He said that the refrigerant needs to be replaced with a new condenser, but the attic equipment doesn't. Is there a mistake here I should correct?

TBH I'm on the fence about selling my home and purchasing a different one so not sure if I want to do a complete overhaul of the system or should just get the system passed on a home inspection. I would hope, in the least, that I can replace this part and move forward with other components if need be, unless it's just a better idea to replace the whole thing at once.

Let me know what you think.

 

I'm not real familiar with R407.

What is the current refrigerant in use..... R410a ?
If yes....I wouldn't switch.
A 5 ton coil is big.
25 lbs of R407. That seems like an awful lot.

 

It’s a better idea to replace the whole thing and move to R-410A.
Pete, 407C is an R22 substitute that works with POE. This contractor is proposing leaving the old evaporator and just replacing the condenser.

 

It's going to cost upwards of $8,000 to get the whole thing replaced. Not sure if it's worth the investment especially if I'm going to sell this house on the near horizon.

 

Look at it this way. You could replace the condenser and have the old evaporator start leaking a week later. Which will require coil replacement. And will require conversion to R22. Then when it’s time to do the condenser again it will need reconverted to R-410A.
Plus if a home inspector picks up on an old evaporator with a new condenser, you’ll likely be giving money at closing for a new air conditioner to the buyers.

 

Well ain't that a B.

 

Reading your past history with this system it would seem that "roughneck77"'s talk of a leak in a week could be more than possible. What confused me on the invoice was the Evcon part number is for a pre-charged condenser. The invoice also shows a charge for an additional 25 lb jug of refrigerant. That seems excessive.

 

It looks like he gave you his cost on material and he is going to charge you $500 above that. (More like $800 if he keeps the jug of refrigerant)

You are taking a gamble keeping the evaporator coil.

I also recommend getting a quote from someone else to replace the condenser and evaporator coil.

 

Can I keep the current evaporator coil with a new 410 but change it later if needed?

*Edit: Sorry if it's difficult for me to follow along. I'm hoping I could keep the equipment I currently have in the attic and replace only what's needed. But it sounds like a full-system overhaul is the best option ATM.

 

No, that’s not an option
