I have a system which has a 4 ton air handler and a 5 ton compressor. I do not think it works properly. Has anyone any experience with this type of mis match. thanks

The equipment you posted is a approved match on the AHRI directory. Out of curiosity I also entered the 5 ton CBA38MV-060-230 model. Here are the results:

The numbers seem strange, but the 4 ton air handler produces 57,000 BTU of cooling with a 18 SEER and 11.2 EER. The 5 ton air handler only achieves 55,000 BTU of cooling wit 17 SEER and 10.5 EER. In this case the 4 ton air handler outperforms the 5 ton model and is more efficient. I imagine the 4 ton costs less than the 5 ton. You Lennox contractor has done his homework by offering the better equipment.

If you have more questions I suggest you start a new posting rather than tagging onto this old one.

Post model numbers, doubt its a rated match, and could cause issues with the compressor.

A 5 ton outdoor unit will not work with a 4 ton indoor coil and air handler or furnace. The freon won't boil off correctly.
Verify this by the mod numbers as mentioned.

Post your outdoor unit model number and we can see if it's a rated match. That blower may be able to move airflow for a 5 ton unit, and your dealer may be right, but it's good to be sure. Ask your dealer for the AHRI reference number, certificate of match.

Here is what i found...

Material: AVY48D3XH21 View Wiring Diagram
Serial number: A0L6110504
Product hierarchy: M13 Air handler 1 pc Stingray
Material Description: AH 1PC ECM 4.0T 25 FLEX HZ YRK
Status: Active

If you look at the airflow data sheet, when you set the "Cool Tab" to A & the "ADJ Tab" to B, you will get 2138 CFM which should be fine for the 5 ton outdoor unit. The evap coils are the same on the 4 & 5 ton models, just a slightly larger ECM motor on the 5 ton, but i would make sure that model number is what they quoted you and not the AVY60.

Hope this helps

Lennox contractor says Lennox 5-ton Condenser, Model Number EL18XCVS060 is compatible with 4-ton Lennox Air Handler Model CBA38MV-048-230. My home is almost 3000 sq ft of air conditioned space with 17 registers which cools all home spaces including 3 bathrooms and walk in closet, laundry room and hallways. What could be some of the potential problems with having an undersized air handler when compared to the size of the condenser?
