OK, I finally pulled the trigger called my installer and told him to order the equiptment.
His proposal was for:
3Ton XL16i Heat Pump (36,000 BTUH) Model:4TWX6036
3Ton VS Air Handler (40,000 BTUH) Model:4TEE3F40A
Trane Three-stage heat,Two-stage Cool Thermostat Model:TCONT802
Trane 5" Media Filter 23.5" Model:TFM235A0AH1
Trane 15kw Electric Heat Model:BAYHTR1415BRKA
(4) 6" Snow Legs Model:BAYLEGS002
I told him that I had a Load Analysis done and was considering using the smaller 3Ton VS Air Handler (37,000 BTUH) Model:4TEE3F37A with no other changes to the proposal except for the smaller 23.5" media filter to fit the smaller AH cabinet.

Sensible Gain 23,586
Latent Gain 4,247
Total Heat Gain 27,833
Total Heat Loss 64,284
His comment was that he did not recomend this as he had a problem with this setup in the past. He did not elaborate. He strongly encourage that I keep with the "matched" 4TEE3F40A. I told him that my only concern was humidy issues in the summer with going with the larger coil. He will be ordering the equiptment tomorrrow. So my question is: Is their really any problems matching the 4TEE3F37A AH with a 3Ton XL16i 4TWX6036 HP?
