    Why would someone over charge a restriction to a point that the suction pressure is too high? The flashing can be heard now. I actually heard it. When I sprayed the water on the condenser, it went...

    Compressor running right at RLA

  9. Why has there been a recent obsession with heat loads (manual J)?

    I noticed there has been a recent trend to blame equipment selection and sizing as the root to a lot of issues. If you go back 5 to 8 years ago, people were not so quick to blame the equipment or not...

  14. Does Trane or other manufacturers require labor warranties?

    Usually, a one year labor warranty is provided for new construction. Can authorized Trane dealers not provide labor warranties with new installs (new homes)? I know builders and contractors are...

    It will give a ball park figure. If the nameplate says 12 to 14 lbs on it, he can drop the whole issue. If it says 5lbs, then he can raise some issues. He's not asking for the exact weigh in charge.
