head pressure control - split system
have a 35 ton unit with an especially long freon run.there are head pressure issues and concern about returning oil and unit use on cooler days may be a problem.
to improve reliability of unit, installation of a device to modulate condenser fan has been proposed (ie. head pressure control); also condenser fan blade and motor to be replaced too.
interested in comments about this idea
