Question about Heating & Cooling

1 Answer

I was trying to figure out how to check the r-22 pressures in my AC unit. It is probably 20 years old, and not really looking to buy a new one. I am not sure which is the high and low pressure sides. I have a gauge but have never operated on and do not want to losse all the r-22. Any heelp would greatly be appreciated. Thanks Mark This is a Rheem classic X rahe-023Jas

    The temperature is blowing at 74 degrees. I was told it is probably the charge in the A/c unit. I was also told that the A/C should blow temperatures around 58-62 degrees.

I'm sticking by my guns based on what you said ... don't fool with it ...

If you insist ... you will have to attach the gages the best you can ... they shoud be color coded ... are you able to purchase r-22 in your area? Can you detect and repair leaks?

Some times the best way to check something is by calling inthe pros ...

Ruud back then had a label tag that would fade out or fall off, the ref is R-22, if you check the supply air temp. and then check to return air temp. the difference is plus or minus 20 degrees (18 to 20pluss ) your good, its called delta t. 20 degrees is good. The 10 is the SEER rating.

I think compressor needs to be replaced, ac unit not pumping any cold hair in the house. I have a weatherking a/c model 10AJA3001, how much eventually it would take to replace it?


You're looking at around $800-$1000 to replace the compressor and if the condensing unit has some years on it (say 12 or more) it would probably be cost-effective to think about a new one, except for the fact you'd probably have to change the evaporative (inside) coil - to match the new condensing (outside) unit because chances are - your old unit is R-22 and you're going to have to put in a condensing unit that will be using a different refrigerant.
All that being said - I would try to find out the reason your AC is not cooling and hope it is a minor problem that can be easily repaired.

We recently switched the thermostat to a/c and it blew out hot air. We left it on for about 20 minutes and the air never cooled. We have a split systerm heat pump. JTF07-048K. R-22 4 ton unit. Is there a...


The compressor for the AC is probably on it's own circuit. The fan will come on but the compressor won't if the breaker tripped. Many times the breaker is outside by the unit. Lift the cover and reset it even if it looks like it's on

Good Luck

I have a 7 yr old coil model number CK3XAA04202-1AAA I now need to replace the outside condenser which is 20 yrs old. How do I find out what ton is the condenser all markings are gone?


You could look at the compressor to get the model number off the compressor which can be traced back to how many BTU's this unit was capable of producing. Also you may have to change that coil that was replaced 7 years ago. R-22 is now a refrigerant of the past. Of course you can still buy the jugs of R-22 but manufacturers cannot make the units using R-22. You are now going to go with a R-410a unit which runs at significantly higher pressures. That indoor coil may not be rated to handle that kind of pressure. Do not let any contractor try to tell you different unless they can show proof that the coil has a R-410a rating from the manufacturer. It may cost more but it is nice to have a matched system.

I am looking at buying a used kenmore 15100 btu unit model 253-355-350 that is supposedly 5-6 years old but little to no use. Is there any issues with this regarding losing some of the coolant? Does it...


This is a catch 22....this is a good unit, but I would try it before you buy. If you get it cheap enough it will pay for itself. Are there more efficient units? Yes , but at what cost? This will be a decision between long term and short term. I would get a new unit if you want long term....and short term if you just want toget by a couple years.

I have a Carrier 4 ton unit model number 661CJ048-A which is charged with R-22 capacity is 9,25lbs. It has developed a leak at the evaporator coil. It has rust on the coils which from what I understand...


First your system is 22 and 134A is a auto AC refrigerant. I have never seen it used in residential ac. I have been in AC business for 45 years. The new refrigerant is 410A or Puron. But you can not use it. Your outside unit is set up for 22. Mix 134A with the oil used in a 22 system is not done. You need to get the correct coil for your system. They are going to make 22 for years. They now have a Drop in for 22 called NU22. I know times are tough but you may have to get a Service Tech anyway.
