Re: Wrong Size AC hose

The thermodynamics of refrigerants dictates the sizes.

Re: Wrong Size AC hose

There would be no issues. Too big a diameter is OK, too small is not.
If the AC is blowing cold, then forget about it

Re: Where is a micron gauge placed when vacuuming system?

"This video says a pump can get down below 200 microns in seconds," Correct. Surely you have an air leak somewhere. Also, the oil level is low. Strongly suggest you change the oil, also, because it is most likely saturated with water vapor, and thus will not pull down very low. Be sure to ...

Re: AC HOSES

Please review the hose sizes posted by Bohica at 9:41 this AM (above)
Be certain the condenser is upside right. You can tell by comparing the line sizes.
The larger diameter line always goes to the top (#8 hose), the smaller always to the bottom (#6 hose)

Re: AC HOSES

Do not bend the pipe on the compressor any further. It can easily be damaged. Insulate that area!!! Aerogel is one way to insulate

Re: What is best way to seal up/get ready a system for later vacuum and charge?

Driving around without a charge in the system, even if it is not gonna be used for a while, is not a good idea.
At the very least, vacuum it down now, and install 12-24 oz of refrigerant. Top it off later when ambients are better.

Re: AC HOSES

Yes, your pic is correct. Be sure to insulate the comp from the very nearby exhaust system. Whoever designed that system put the pump waaaay too close to the exhaust. Your performance will be compromised

Re: Does air get in system when using AC manifold gauges?

"Do I need to be worried about getting air into the AC lines simply by hooking up my gauges to read pressures? Should I be vacuuming out the manifold before hooking it up?" No. The system pressures will be higher than atmospheric (both hi and lo sides) at ordinary temps. For example, the P...
