If I change 2 tong aircondition compressor to 2.5 tong. Is that mean that I have 2.5 tong unit?

Someone told me that 2 tong central air condition evaporate coil can work with 2.5 compressor. The question become once I upgrade compressor to 2.5 tong, can I claim that I have 2.5 tong unit? Will I see the difference of cooling power?|||It will not work that way but if you were oversizing the evaporator by half ton it will work better at removing humidity . If the condenser is over sized then your system will begin to freeze up and you would see much lower suction pressure with that configuration .If your evaporator has a orifice type metering device you could change it to a 2.5 ton orifice but your coil size remains the same, so best solution is to keep your system matched or only up size the evaporator by half ton .|||You will have no problems with the change over most of the half ton unit compressors are rated .5 tons of colling above. I have replaced thousands of compressors and done it more times than I can remember and have not once had any problems.|||That is totally wrong. You do not want to connect a 2.5 ton compressor to a 2 ton system. The system is rated not just the compressor. The system is rated on how many btu/hr it can remove. 12000 btu/hr= 1ton of air conditioning. The most heat your 2 ton evaporator is going to remove is 2 ton.

You will probably be better off replacing your evaporator coil with a 2.5 ton coil with a TXV. You will get much better cooling performance.





A good tech will be able to determine if a larger evaporator will benefit you.|||IF the larger compressor is properly set up,


it will just cycle faster, and the cooling power


will be unchanged.


If it's not properly set up you can freeze the


'2 Ton` evaporator unit.


The final stage of the system is the evaporator,


and its capacity is based on the air flow and


heat transfer area it offers.


If the evaporator is a bit over-sized you might see some


increase in cooling, but, in general, it is not


a good idea to mix units with evaluating the engineering.
