You can find the tonnage in the model number which increases by increments of 12, so if the model number is 24 =2 tons. Model number on your a/handler is 17. Thats a ton and a half. Really should match the evap and condenser for the best efficiency. ...

This should cover it.

Take your scams and ... never mind.

You need to look at the nameplate of the indoor unit .If it's a 1 ton unit it will not work with a ton and half condenser

Hi, yes the number you are showing me 036 indicates its a 3 ton unit. For every ton of cooling, you will have 12,000 btu's of cooling. 36 divided by 12=3 ton unit. Its showing me also its a Ruud Handler 2.0 ton which would be a Model# UACC-024JAS? If your mobel number is the one you gave me, UACC-036JAS, this is a 3 ton unit, absolutely no questions. I hope I have been of help to you. I am a licensed air conditioning / Refrigeration /Heating Contractor. Let me know if I have been of help.

PS If this is a split system with the indoor air handler and condenser outdoors, both coils must be the same tonnage for it to work for you properly. You can't have a 2 ton indoor evaporator coil with a 3 ton condensing unit.

It is a 3.5 ton air handler and without knowing for sure about Rudd only making those sizes which they should, they more than likely would have gone up to a 4ton coil. One way to cross check this, is to see what ton the condenser outside says it is. If you have a 4ton condenser, then you should have a 3.5 to 4 ton coil, either being okay. What you don't want, is a 3 ton coil and a 4 ton condenser and so on. A half ton isn't going to be a problem regardless, but if anything, you can always take the measurements of the coil if you are trying to replace it.

I could not find a "fault code" list for the LA125HV but for thier Multi Split Units LG lists code CH7 (C7) as "Indoor Unit is Set in Different Cool/Heat Operation Mode." So maybe your air-handler tihinks it's in Heat mode will the compressor is in Cool mode, or vice-versa....

That is a fairly large difference. It is usually ok to have the inside evap. coil and blower up to 1 ton larger than the outside condenser. That will make the unit slightly more efficient as well as less likely to freeze up on low airflow situations. It is not recommended to install a new condenser on an old evap coil. There has been a lot of changes to the design of the coils in the last little while. For example a 10 year old 2 ton coil may only have 3 cubic feet of volume but a new 2 ton coil may have 4 cubit feet of volume.

There are many factors that may have infulenced the decision on what size condenser to install. Many of which can only be done by visiting the home and doing alot of work, checking the duct sizing bioth supply and return, inspecting the insulation and windows of the home etc. etc. Most of the time that never gets done. You can blame the contractor for not doing a complete check, but at the same time you can blame the customer because many contractors that are that good loose the job to a cheaper bid that did not no any of the research. It is a catch 22 for everyone involved.

There is ALOT more to sizing equipment that many people think, sadly that also includes many HVAC contractors. Way too many people use "rule of thumbs" or flat out "guess".

Sorry for the rant but your queston can only be answered by a good well educated HVAC contractor visiting your home. That type of a contractor is getting hard to find these days in such a price competetive world.
