    I respectfully disagree with Beenthere about the minimal SEER increase by adding a TXV valve. I indeed find that with those cheaper, very small condensor 10 SEER systems the efficiency gain is lower,...

    Add TXV valve

    You can also talk with your service professional about the possibility to replace the metering device with a TXV valve.

    I hope I don't hurt anybody's feelings, I'm not a firm believer in heat pumps for heating.
    I'm sure that the claims they make are valid (e.g. COP 2.8). This makes that for every KWh you're using and...

    I was reading some articles and stumbled onto a pdf explaining the benefits of a new refrigerant Ikon B.

    It is supposed to be a drop-in replacement for R22 and yields a better cooling efficiency....

    Davidr my mistake. I also believe that duct losses are far from neglectable. My question should have been:

    What is the value of the SEER rating?

    I can't help it, the more I think and read about it the more I doubt the value of the SEER rating for people living in Southern states.
