A/C problem, need help ASAP

Steve, mine does not look like a plug, more like three terminals.

I am not sure if there is an overload.

Now that we know that what you have is *probably* a Goodman/Janitrol, or an Intertherm, fill us in on a few more details... Is it a house or a trailer?? Is it gas heat?? or electric?? The answers will determine what recommendations you will get. While you are thinking about replacement, check this link for a little food for thought.

It is a "Tempstar".

It is a house, about 5k square feet if I count the finished basement. Gas heat. I am going to read that link now, thanks.

It's probably 5k "before it goes throught the transformer" for your home service.

You're right! I should probably think of it that way.

Darn, now I'll be afraid even to plug in a lamp.

I should have said, "typically". You won't find them at Mouser or Digi- Key.

most likely you will need a new compressor from DIDO

Typical Al Gore EPA baloney. This only applies to certain "developed nations"; the rest of the world will make more R-22 than we ever did or would have. Just like has happened with R-12. Look what's happened to the ozone since!

Investment tip: Get the EPA license

and stockpile R-22. The people that did this in the early 1990s with R-12 bought it at $1/lb and sold it for $50/lb.

Where you at? 13 KVAC hereabouts.

They are thermallly protected internally for the most part with this type compressors. If one goes off on the overload its not going to reset until the compressor cools down period.

Sounds like a compressor burn-out.(Dead short) But that would have obvious when checking the compressor terminals (wires removed) resistance.

A compressor locked rotor does not trip circuit breakers right away if at all. Normally the compressor overload trips first. Or fuses at the disconnect. You can find the LRA on the top of the compressor. (3 1/2 ton a/c about 95amps)

Just for reference:

A 15 or 20 amp breaker can usually take being tripped several times

A 30 - 50 amp breaker can not take the heat when it trips repeatedly. Yours should be replaced when the problem is corrected. A weak breaker might not cause problems until hot weather.

A 100 amp circuit breaker would be lucky to trip one time without damage.

Yep, that is indeed the case. I will get a whole new system.

According to Noon-Air :

Hmm ... are there substitutes for R-22 (HCFC-22 in their list)?

If not -- are there satisfactory refrigerants for the purpose with a change of compressor and A-coil?

If not -- what will we do with global warming?

Enjoy, DoN.

Why would they do that? the "rest of the world" aren't manufacturing heat pumps to use R-22 any more.

That's a ridiculous assertion. Look at the biggest HVAC brand in China, Haier. Everything in their catalog is R-22.

China is in the midst of a huge retrofit to air conditioned housing in the cities. All the old Stalinesque high-rises are now covered with R-22 mini- splits.

R-22 has superior physical and economical properties to any alternative. No one is going to abandon it except for political reasons. And in the third world, physics and economy still beat nutty environmentalist politics.

It's fun to blame Al Gore, I'm sure, but the Republicans have ruled the EPA for 5 1/2 years now.

That's what it says.

So what's your point. They won't be selling it here, except as the schedule provides.

I don't think you read the chart very carefully. It clearly states that R-22 will be available in the US for ACs made before 2010. And that that will be its status until 2020, after which it won't be legally available IN THE US.

If other countries, don't accept the Montreal Protocols, that's the way it is.

Just like has happened with R-12. Look what's happened to the
