    return blocked. a-coil dirty. bad filter. bad blower. all would cause high head low suction. could be any number of things. get a real tech that actually investigates instead of changing parts.

    He is a real tech. Maybe not so good of a friend. I have added freon to older units many years ago, but that is the extent of my hands on work on A/C units.

    Thanks for the lists of usual suspects. I know what a dirty coil looks like. I know what the blower thingy does too guys.

    His assistant did a lot of the work. It seems like if a helper is any good, they start their own company.

    I will try a picture. I am new to this.

    This solder connection (read: weld) was done at installation 2 years ago. It joins the existing 3/4" vapor line to a 90 degree 7/8" elbow. Note elbow is crimped to form partial mechanical connection to vapor line.

    These days my imaginary friends are all in PC games. All my enemies are there too.

    you better pull out you refrigeration book!

    head pressure will not rise due to return blockage, a dirty Evap coil, dirty filter, or bad blower!

    your diagnostic opinions are not accurate!

    A dirty condenser coil would raise the head pressure.

    Are you trying to stop the entertainment.
