I stand by my statement if the suction is sloped towards the compressor in the slightest amount. If anyone has any specific situations where this is not true, lets hear them. (I haven't seen every type of install possible, obviously.)
it was working.... played with it.... now its broke.... whats the going hourly rate for HVAC repair
Slope in pipes towards compressor is so important for oil return. I had an opportunity to repipe a 10,000 sq ft freezer that was not properly sloped. Before the job we constantly had oil problems and endless compressor failures. Afterwards never lost one compressor! It was an older system using Carlyle 5F40 compressors. It took some time to convince the customer it was a major issue with his system. Now he is my best customer and sends me tons of referrals.
