Completed AC replacement. Recovered refrigerant and removed old condenser and coil. Installed new coil in the plenum above furnace and set condenser on a new pad outside. Flushed then reconnected the lineset. Pressurized the lineset with approximately 320 psi nitrogen to test for leaks. Left nitrogen in lines until spring when we come back to do the start up procedure. Thank you for choosing Black-Haak. Please take a moment to fill out our online survey. Thanks, Craig.
