I have a home air-conditioning unit that is about 12 years old that I would like to replace. The unit, I was told the last time it was repaired, uses Freon 22 and is considered as being closed to its end of life. The unit is currently operational although is not cooling as fast as I believe it should. In a recent mailing I received from GSM there is a "Home Health Confort Care Package" advertised that got me to consider replacing the air-conditioning unit I am concerned about.
