How Sufficient is Vacuum Pump made from 1.5 Ton AC Compressor

Hello Everyone,

I started learning ac repair and converted my Samsung Ac 1.5 Ton Rotary Compressor into vacuum pump.

I would like to know is it sufficient for pulling air and moisture from the system?
It become very hot when pulling vacuum for more than 20 minutes ?

It is not sufficient.
Compressors are cooled via refrigerant vapor. When no refrigerant is flowing they quickly overheat.
They will also not provide low enough vacuum to properly evacuate the system.

A vacuum pump for A/C work uses rotary carbon vanes for maximum suction power.

historic home needs better AC return air venting

C

Cheryle Fuller on Aug 02, 2022

I have a historic home I have an accommodations business in. This means many of the rooms are closed most of the time, but the 3 up front have transom windows which are left slightly ajar. The back ones are the issue. There are 2 different joist levels between the 2 main rooms, and angled roofs above the side rooms. (Envision a simple farm house with gabled ends, although joists heights are not the same) The original 5 ton central unit is up front tucked under the closest roof line to the rear of the house. It was the only place to have a central air return which is what was normal when this was added in '99. There have always been issues with some rooms not being cold or too cold. Many discussions have been made with contractors but none really seem to have a solution. All are very reluctant to do anything. There is one large ductboard air duct coming from the front to the rear which the rear ducts come off of on the S. side of the house handing where a finished room was in the 1850's. This is also the part of the house with the lowest ceiling Downstairs (Fachwerk is 9', kitchen behind this is 10', Victorian Eastlake up front is 12'). I can bring a small 4-5" duct from the side room to this area through the brick wall supporting the rafters, as well as one from the next room and this room, to join a larger duct, but there is a limited access to the main air return on the other side of this roof line, due to the valley above the air return/furnace. Can someone suggest a type of filter for these? Would a box built to accept the smaller return ducts in the reverse of the air handler up front be suitable for some type of filter? I think I can collect these ducts in front of a larger box to hold the filter (which would have to be a long use filter needing changing only every 6 months), then have a specially made flat duct to go under the roof valley to the air return a foot or so away . My thinking is that any type of return air for these rooms will be helpful. Then the question would be where would I find small round ducts and covers? Preferably wood, because all my ceilings are painted 1 x 6 T&G. Any other suggestions would be appreciated barring some massive huge ducts that make the room all about the ventilation instead of the history. P.S. I just had the attic and floor joists foamed with closed cell insulation. I am hoping the huge utility bills will come down at this point. Read More

Use of nitrogen while brazing

F

Fixologist on Aug 04, 2022

I have watch a number of different services braze the copper lines on A.C. condensers and up to now, none of them used nitrogen to control copper oxide in the joints. I can on attribute not doing it to the following reasons. If I am off base in my reasoning, I would appreciate any correction and information on just how important brazing with nitrogen might be or not be. 1. From experience, those that do not do it have found it not to be as necessary as others claim it to be. 2. It takes more time and another step in the job as well as extra costs involved that lead to less profit for the job. 3. If the oxide does create a problem in the system, it probably will not show up immediately leading to another service call.Read More
