They have almost finished installing the new 1.5 ton goodman (15 SEER) unit.
They will be charging the system soon. What should I watch to ensure it is done correctly? Temps are about 75 F outside at the moment.
Also, how do I tell if a TXV is installed (isn't one required to achieve the 15 SEER rating?).
Thanks and thank to those that responded to my previous post!!
