has anyone come up with a good formula to provide an efficiency rating for a package dx unit with a dx evap and water cooled cond. i would like some type of rating system to combine each component of the unit ie:compressor blower motor, evap,cond,...the eer rating is nice but i would like to know how everything is performing individually then combine that and come up with a percentage rating
