I guess I don't understand. You are using the EPA estimate as the prior standard? I would suggest running the unit as is, without the modified thermostat, and NOT using the EPA estimate. Then you have a true baseline allowing an apples to apples comparison.

It could be that the new thermostat is better - but why? The insulation is the same, the compressor is the same - what is different?
