Re: Temp dif split
Just to clarifiy how we report the cooling system in Tx.-- which makes the TD (an indicator only) more important than if it were to include the ducting and vents as some might otherwise think;
Our reporting system is broken down into three categories, not just heating or cooling, but separates the ducting and vents as a stand-alone item of reporting.
Having separated out the Ducts and Vents from the Heating and Cooling section does make the temperature differential a little less subjective than if the ducting and vents were in that equation. However, it does nothing to validate the cooling system if the coil cannot be fully observed-- which you won't be able to.
I do wonder how many folks out there actually report the temperature differential when the split is too high... The lack of reporting of this condition can and may cause degridation to the ducting and insulation from the sweating. Our Texas summers are partcularlly damaging to units installed in the attic when the split is too high.
