A/C charging

[xaisomboun]

Anybody know a good shop with decent prices that can charge a dead empty A/C system?

Freon is expensive. If you pay to get it recharged, make sure you get the leak (if there is one) fixed. You could also look into the DIY R134A conversion kits.

You can get that stuff at the auto store now days.

Remember you cant just add xxxx amount of freon to an empty system. You need to pull a vacuum on the system for at least a half hour to make sure all the moisture and air is out. It is good to replace the drier if you are re-doing your a/c system as well and to make sure the correct amount of pag oil is in the compressor.

Youngstedts in maple grove, great prices even better service.

Waiting area is pretty nice too.

Does the conversion kit just involve compatible orings and the new service ports?

Where can I get a kit?

Thank you kind sir! :)

You can get a conversion kit at any parts store. The majority of the conversion is changing the connectors to R134a from R12. You will still need to get the system properly recharged.

Freon isn't bad, you can get it for $10/12oz can (R134a) at Wallymart. 2 cans will fill most systems.

I bought the A/C service manifold at Harbor freight and have done a few cars with it (you need to do the R134a port conversion first, just the two screw-on fittings). You can even get an HF vacuum pump to pull a vacuum before charging. I'm sure I didn't get all the amounts right, but suction and discharge pressures look good and the system blows cold air! Beats paying $300+ for service like you do at most shops. Just have to make sure you also get a somewhat apropriate amount of oil into the system.

Basically if i'm charging a dead system in an unknown state, i just slowly start to put a can into the system, then stop and listen for leaks. You waste a little freon, but you can usually find the leak (if its big) pretty reliably. And if its a slow leak, depending on HOW slow, a charge may last you a couple months, which will get you through a summer. Thrifty comfort :)

FYI
Freon is just Duponts brand name for their refrigerants.
Have you guys heard they are doing away with R-134a? They are going to start using HFO-1234yf it has a 99.7% lower global warming potential than R-134a.

Add some a/c dye when you charge it, so if there is a leak present you can easily find it.
