Buying a house and this is the current AC unit. Looking for thoughts and input as to whether it should be replaced even though the seller says it is functional. In my opinion it cannot be working efficiently with all the fins missing and crushed fins. Any input is appreciated. Thanks

It's seen better days. It's definitely going to be running hotter then it needs to be, if it's not already leaking. Get the quotes rolling, wait for the shoulder seasons and you'll get better prices.

Cheers!

If you can reduce the cost of the house by that of a new unit after getting an opinion, can try to block off the area with no fins. It should cool but at slightly reduced capacity/efficiency.

If you replace...

If the dog urinating on the coil isn't the seller's, the problem will recur.

Get the installer to not connect the ground and wire one of the hots to the cabinet; will protect the next unit from people bending fins and pesky urinating dogs. *no, don't do it.

If it was mine, I would check if the remaining fins were somewhat passable for air, and if they were I would block off the corroded section and run it and see if it performed without an undue electric bill, before just summarily replacing it.

Charge may also be low if that is really a frosted suction line.

At the same time, you know it is going to need replacing sooner or later so if you have the money you might do it.

But there is a significant chance that it might still perform adequately, and then it would be money spent too early from an economic standpoint, to replace it now.

This is an older thread. The OP probably has moved on already.

..

It's not going to be too early looking like that. Even if it works half way, it's still on borrowed time and using excess electricity. (There's going to be a significant amount of separation of the aluminum fins from the copper tubes. Even if the aluminum hasn't completely fallen off, it's not conducting heat well.)

The moment I see something like that, I recommend replacing the coil, or in small units like this, the whole thing.

Cheers!
