A/C Condener replacement (5 Posts)
A/C Condener replacementHi, I have a 2 ton Rheem A/C Handler R410A coolant & would like to know if I can use a Trane XL 14i 3 ton condeser also uses R410A coolant as an replacement unit.
Please advise. Thank you
"Can" or "Should"?If you are asking if you can, the answer is yes. If you are asking if you should, the answer is no.
As expected, you should make an effort to match not only the capacities of the indoor and outdoor units, but also the manufacturers of the equipment.
Having a 3-ton condensing unit and a 2-ton evaporator coil will most likely result in lower operating pressures and temperatures that can lead to the freezing of the indoor coil. As the air filter gets dirty, the freezing effect can become worse.
In addition, a three-ton condensing unit has a, give or take, 3-hp compressor that will use significantly more electricity than a 2-Hp pump.
Using a Thermostatic expansion valve on the system will help things a little. Also, a longer line set will help bridge the gap in capacity, although its effect will be minor and is a major contributing factor to system inefficiencies.
So, to make this short and sweet, yes, you can connect these two components but the result will be poor, the cooling effect may very well be less than 2-tons and you will spend a lot more money to run the equipment.
If this was for my house, I would tip my hat and say, No Thanks!Eugene

I dont want to start a warbut you should never oversize your condenser on a HVAC system, yes in refrigeration systems, but no on residential HVAC. I know and the professor knows in certain load requirements but these are 99% of the time on commercial applications but my friend I don't mean to be cruel but it is very apparent you do not have the knowledge to make this work.
PEACE BE WITH YOU

Condenser ReplacingHow to replace the condenser? What things are required to keep in mind? Please advice me.
Cond replaceHeat , I agree w/ The Professor and David Broome.
smithwatson, lots of knowledge, lots of tools, lots of test tools and instruments, lots of copper /fittings, lots of miscellaneous electrical parts/fittings, and an E.P.A. certificate.And Freon .And solder/brazing skills. And about 4-6 hrs of labor. Are you in the trade?This post was edited by an admin on February 5, 2014 9:45 PM.
