In this edition of the Btu Buddy series, Bob is scheduled to help finish a job that a new construction crew installed. The installers left the gas line and liquid line on a heat pump at the jobsite turned up all weekend and it rained in the tubing. The foreman noticed it and asked for the service department to finish the job.
Bob arrives at the job and sees right away what the problem is. Sure enough, the new construction department has made a mess of this one. The installation crew had run the gas and liquid lines out to the outdoor unit and just turned them up on the ends, with every intention of plugging them before they went home for the weekend, but they didn’t. There were no gutters on the house and water from the roof just ran in the lines. The lines had a fairly long horizontal run and all lines were standing full of water. This would be the end of these systems if they were just connected to the outdoor units and started up. The foreman had made a good call getting the service department involved at this time.
