I need your advice on how to fix an American Standard air conditioner.

That’s not a surprise. The simplest way to fix it is to rip it out and put a different brand in, barring Bryant and Coleman.

I want to fix it, not buy a new air conditioner. What goes wrong with them, and how can I fix it?

American Standard units tend to freeze up.

Oh, the motor goes out?

Yes, that happens sometimes, but they actually freeze, too.

It is an air conditioner. It should get cold.

They tend to generate a lot of condensate that the piping cannot handle, so you’re prone to water flooding into the house if the pan or drains have issues, which they do.

I’m glad I do not have that problem. The upside is that I can clear out the drain pipe myself after mopping up the floor.

They also tend to freeze up literally, with all that condensate plus the dirt on the unit acting as insulation until it gets so cold you have ice on the unit. At that point, it either cannot exchange heat well or stops until the ice melts and floods the house.

So I put cleaning the AC coils on my chore list. And I’ve heard ice could form if your run it when it is less than sixty outside.

American Standard units tend to have their condensers, coils and valves leak. And in that case, all that water can freeze where the refrigerant is escaping.

Refrigerant is expensive to replace in any case. Fortunately, my AC does not look like it just escaped from the movie Frozen.

The frustrating part is that the government restricts the sale of refrigerant to licensed HVAC repairmen, so you cannot recharge the leaking refrigerant yourself.

What else do I need to look out for?

Another problem with the units are the evaporator coils.

That I cannot fix myself. How does American Standard customer support do in that regard?

Good luck getting a replacement part under warranty, because American Standard takes forever getting you the part.

Just in time inventory has made that a common problem for HVAC companies.

The problem is worse than the parts not necessarily being in stock, but more from sheer demand. And getting them to pay for the parts under warranty is a hassle, while they never pay for labor.

I wonder why they leak so much.

They have thin copper coils that are prone to cracking, breaking, oxidation and so forth. You can use no-weld stuff to try to slow a leak until a repair person gets to it, since it will be a while with American Standard.

No wonder you joke that the American Standard units are the ones that failed the Trane quality control checks.
