Is the unit outside the one sweating ? If it is that means it is working really well. Pressure should only be set by maximum efficiency and nit to change condensation.

What's wrong with your current AHU? Any Ruud dealer can assist you. Most 4 ton units work with r-22 or 410a. As a side note, most parts in an air handler can be replaced unless the case is rusted thru.

Only if they are still available in your area. Goodman still has a few R-22 units left in Texas the last I heard and that is only if your local supply stores can order them. They are getting to be far and few between since they have stopped making the equipment. You might also get a second opinion, a lot of companies are just trying to benefit more by replacing everything, but you could still have a R-22/410A compatible indoor coil and copper line set, they just have to use a flush kit to get all the old refrigerant out of the system. 410A is easily contaminated and runs at a lot higher pressures, that is why they want you to replace everything, but there is still hope. It will save you a little money just having the system flushed and replaced with 410A condenser, but only if compatible. Hope this helps and good luck!

The old 410A fittings are different than the r-22 fittings. There are adapters available on ebay. Remember 410A runs at higher pressures than 22. Be sure to use gauges for 410A! Use the right gauges with the right hoses! High pressure.. Use the right gauges and the right hoses!

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.

Going to replace hvac system. Don't know what


Hello,
According to the model number it is a 2 ton or 24,000 BTU unit. It is very important that you change the indoor coil as well as the outdoor section, due to it being a 10 SEER unit, and the new basic systems are 13 SEER, the old coil cannot handle the higher SEER ratings.
Rheem and Ruud are the same equipment, just 1 number different on the model number.
I hope this has helped, please rate the new guy :)
Please contact me if I can be of any further help to you.
Have a great day!
Sincerely,
Paul Gibson

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

A/C coolant requirements, replacing both units


That is true, what the company told you, due to the gov't upping the minimum S.E.E.R rating (Seasonal Energy Efficiency Ratio) it is heavily recommended by everyone in this field to replace both. It is a lot of money in this economy to do this but your energy savings in time will pay for it, I'm a Carrier kind of guy personally and with the new tax credits the government is giving for energy saving the Carrier Infinity which is the Cadillac of A/C units, is very cheap. Plus from experience it has saved my customers up to 65% on their electric bills
