I have a carrier heat pump that was installed in 94. I am trying to find out what the seer rating is and find a superheat chart. The name plates says to charge by subcooling 9 degrees with a txv. I dont have a txv, I have the fixed orifice. I searched carriers web site with no luck. Any ideas? My model number is hc1bn030-a. Thanks.
