You see a lot of them on the smaller tonnage Rheem Rudd heat pumps that are high seer units. They do this because often times the indoor coil can’t handle the charge in heat mode.
When pulling a vacuum on an existing system, will remaining refrigerant oil in the tubes affect your vacuum reading? In my mind the oil will evaporate just like water and ruin your vacuum reading?
I have over 20 videos on vacuum. Refrigerant oil will not be affected by vacuum. It will take longer to pull the moisture out if existing oil and only driers can remove all the moisture from POE oil . Get the book, Review of vacuum for the service engineer and you will learn a lot and it will clear up these misconceptions.
Good job 👍👍
