    do you have licenses to handle and purchase Refrigerant?

    do you have equipment to recover the refrigerant?

    do you own a torch and solder and silver solder rods to solder compressor back?

    Do you own a vacuum pump and a micron gauge?

    do you have access to filter driers?

    is old compressor shorted out or a no pumper?

    are all of your run capacitors ok?

    are all of your start capacitors ok?

    is the replacement compressor identical to the one you are removing?

    is it a heatpump or straight A/C?



    let me know if you have all of this to this point and i can help you further

questions:
1. how do you know when the compressor is bad?
2. how much should a dealer charge us to replace under a warranty? an est. would be great...
3.Is the warranty still valid if an independent contractor installed it, is no longer in business?

SOURCE: compressor size

Square footage is how you determine what size of an AC you need, say two bedroom house with 1500 square feet would require a 3 ton unit but I would go to a 4 or 5 ton depending on brand and what you may do in the future, Like adding a bedroom or bathroom and how many people will be living in the house, a heat pump normally last longer the bigger it is and is more efficient than a smaller size. Just think like this, a 3 ton will run 30 minutes to an hour longer to cool the same space as a 5 ton so if the five ton does it 30 minutes faster it will not run as long. And when it has to pull down the temperature again it will do it much faster. So less run time means faster heat or cooling and less energy is used. I have found that the bigger units are made better and last longer as a general rule. And to understand the 3-ton and 5 ton let me say that it means how long it takes 3 tons of ice to bring the temperature down 10 degrees, the old BTU’s British thermal units. However the bigger the unit the more well built it is normally and the less maintenance required. 5 tons of ice would get it cooler faster. But one thing to keep in mind a heat pump is only good for 20 degrees temperature range, for instance if the high range is 80 then the low side would be 60 in order for it to be efficient so if you have it set in the house at 72 degrees on the high side and low side would be 52 degrees. But the larger the unit the less time it would take it to recover from the heat differential.

SOURCE: Replaced my 5-year old 3-ton 12 SEER Goodman outside condensing unit with an older 3-ton RUDD condensing unit because of lack of funds. Now the compressor has gone out on the RUDD. Is it better to rep

A new unit will be 13+ seer unless you can find someone that has replaced a compressor or has one left over from pre 2006 stock. Our wise Government with all its resources decided that we aren't smart enough to turn off the lights to save energy, so they chose to end the med and low price lines. And the same bunch of smart ones decided that now R22 because of its chlorien content being bad for the air (5% of what R12 was) so we have R410A and others that no one knows how much cancer or daMAGE THEY WILL DO OVER TIME. So now if you replace your AC unit out side with a new one be sure its compatable with the refrigerant inside and beware soem manufacturers wont stand up to full warranty if you dont buy an indoor coil and rerplace it too.

We get what we deserve in Washington DC and if our guy didnt support this stuf too many other folks guys did. We just dont talk about it enough. AND WE SHOULD. But then again you like me are probably RITCH. So we have to give up our wealth to the government so they can redistribute it and buy more votes. And we can stay working too much to talk about it.

Just burns my back side like a 4 foot flame.

Read tween the politics and you'll get my recomendation.

Buy your self a compressor and get someone qualified to install it or see if the old goodman one will interchange easily.

What is the HP rating if a 3 ton air conditioner?


Hi, this depends on the compressor that is installed in this unit. It may be a Copeland scroll, a Tecumseh, its hard to say. Most compressors are around 2 hp for a 3 ton unit. On the data plate it will tell you the h.p. of the blower and condenser fan motors such as 1/4 h.p., or 1/3. If you can get the name and model numbers from the top of your compressor, you can call a a/c, Refrigeration parts house, wholesale and they will have it in there manuals. The B.T.U. rating for your compressor is 36,000. There are 12,000 BTU's per ton of cooling, this is something that almost no one knows, but now you do. If it were a smaller unit such as a 2 and 1/2 ton, it would be 30,000 B.T.U.'s. You can look at the model number of a unit and you will see numbers like this, 024, 2-ton, 030, 21/2 ton, and 036 a 3 ton unit and so on. Your compressor alone will be in the range of a 2 horse unit, which ever the brand of compressor they installed in it. Please don't forget to rate me on this as I know you will be kind. I will be here if you ever need help on repairs or trouble-shooting your unit in the future, just use my user name below.

Compresser is shorted out across the fields. I want to comfirm the compresser size before I replace it.


Hi,
You need a niminal 3 ton compressor...the "36" in the model number gives you the 3 ton rating...36000 BTU @ 12000 BTU/ton = 3 ton...
So you need a 3 ton 240 volt single phase compressor...

Do you know how I can get a Goodman Ht pmp Manual


this manual willl not help your system perform better , have a qualified tech check your sub-cooling. temp diff, and match your piston with your coil. many goodman systems may say they are 3 or 4 ton but are half a ton smaller than advertised at the compressor. a three ton system will have a two and a half ton compressor

Compressor kicks out and it's new


First of all, clean your outside coils so that you are assured of good cooling air. The compressors have an overtemp device that is usually internal to protect them against heat. If you have an air compressor use it to blow out the coils good. If the compressor will start, the capacitor is good so it sounds like a cooling problem with the compressor

12AJB42AO1


Hi, Check the mod # again. They don't have a 4L. If it is a 12AJB42AO1 it is 3.5 ton, If it is 12AJB48AO1, Its 4 ton. Not sure of the KW but it should have the Amp draw listed on the name plate although it probably wont draw that much. If you want to see if it has a proper charge in it, the suction line should be sweating all the way to the compressor but the compressor should stay pretty dry. If no sweat back or if its froze, its probably low, If compressor is all wet, Its overcharged. Hope I have helped. If not, please go into more detail on what you need. kstfas
