Question about Whirlwind FH-778 Air Conditioner
Unit is freezing up around the lines close to the outside unit.
Freon is low. Sounds counter-intuitive, but the large return line should be cool( even have condensation on it) but never cold enough to freeze.Either use factory pressure settings or add just enough Freon until Ice melts. If unit has a high-side sight glass there should be no bubbles present. Do not overfill.
