 Very Pleased - DIY AC Repair Jan 31, 2011
By J. Hudson
Recently we had a hot spell (in January) and I noticed the air conditioner in our car was not working very well. I did a quick check under the hood and everything appeared OK, so I figured the AC system was a little low on Freon. I took the car to the local Nissan Dealership for a "recharge" and was surprised when they called me up and wanted $500 for repairs!
It seems the low pressure AC line was leaking - which made sense because the Freon had to go somewhere and I did notice a little oily residue on one of the hoses when I checked under the hoold. The dealership wanted $175 for the hose and the other $325 was for labor and the 1 lb of freon it would take to refill the system. A quick search on the internet indicated I could get the same OEM low pressure hose for $111 (delivered) so I asked them if they could evac the system so I could do my own repairs. Note, if there is any Freon at all in the system, the responsible thing to do is have a repair station remove it so that it is not vented to the atmosphere.
The dealership actually did the evac for free so I picked the car up and ordered the parts to fix it. While waiting, I did some more research and decided to recharge the system myself. Once I repaired the hose, I could take the car back to the dealer and they would refill the system for me for $129. That would put the total cost of the repair at approximately $250 - so almost half of what they originally wanted. However, I decided to buy the tools so that I could do it myself - which initially cost me more money, but then I had the tools and I could work on my other cars.
First thing I needed was the Vacuum Pump. You actually need to size the pump to the type of equipment your working on and for a car air condition 1.5 to 3.0 CFM would be about the right size. I liked the quality of this pump and after reading several reviews I ended up buying it. Note - Harbor Freight has a vacuum pump that looks pretty much like this one if your interested in saving money.
I was surprised by how small and heavy the pump was when it came in the box. Although the pump is shipped without oil, they do test these at the factory and there is still some oil left inside when they ship them - so don't be surprised if you find that oil leaked out onto the pump. They do include a bottle of oil to fill the pump before first use - be careful not to overfill it - bring the oil level up the the line
There is a T fitting with two different sizes. The fitting that comes off the side is a coarser thread and that is what my manifold gauge set connected to. (The fitting that comes straight up is a finer thread) To properly use the pump, you also need a manifold gauge set which I purchased on Amazon for around $100. My car AC uses R134a and I easily connected the gauge set to the AC system and then to the pump.
After I replaced the leaking hose (about 15 minutes of work removing 3 bolts), I then "evacuated" the system with the pump. A "deep" vacuum that this pump can produce will actually cause any moisture that is in the air inside of the new hose to boil off into a vapor and then be sucked out. Moisture in your AC system is a no no. I let the pump run for 30 minutes and then shut it off and used the manifold gauges to check for leaks. I waited another hour and the system did not loose any vacuum so I was ready to recharge it
The best way to fill an empty AC system is by weight - there should be a sticker under the hood that indicates how much R134a your system requires. On my Pathfinder it was .99 lbs or call it 1 lb. R134a is sold in 12 oz cans - you get them from Walmart for $10, so since there is 16 ounces in 1 lb, I would need two cans. I also purchased a valve/tap to pierce the can and connect it to my gauge set
Refilling the system was pretty simple - I emptied the first can completely and when I started on the second can I weighed the can on my postal scale when I started and when it was 4 ounces lighter, I knew the system was full. You can also use the gauge set to try to figure out when the system is completely recharged but the pressure depends on the ambient temperature and other factors, so charging by weight was a lot easier for me
Cost of my DIY repair > $111 for the new hose, $136 for the Vacuum Pump, $118 for the manifold gauge set, $11 for the can tap and $20 for the Freon. Total was $396. So I still saved over $100 and I now have all the tool for future repairs and the satisfaction of doing the job myself. I am also planning on using the vacuum pump for other projects - like brake bleeding, etc

Better than expected Mar 23, 2009
By Luis E. Alvarez
"Maximus"
This vacuum pump worked better than I expected, when I did the vacuum test in my car the needle on the gauge was steady. I did this test three times to verify accuracy and the three times the gauge read exactly the same. I highly recommend this Vacuum pump.

What a nifty pump! Sep 30, 2009
By D. Jensen
I purchased this pump to evacuate glow discharge tubes of my own manufacture. It came highly recommended yet I was still pleasantly surprised at how well it pumps and how quietly it operates. I'm not sure how anyone can make a profit selling it for $99, but I guess that's for someone else to worry about. I'm just very happy to have it! Delivery from Wholesale Parts & Tools was just three or four days.

Great Vacuum Pump Aug 20, 2009
By Kenneth Southerland
The shipping on this was a little longer than I thought it should be, but the wait was worth it. This is an excellant pump at a very good price. It tells you that the time to use it is 45 minutes to an hour. My system was done in 15 minutes. I bought this because I was tired of being robbed at the garages. I had not done A.C. work before, but it is much easier than they want you to know. I saved more than $1,000 on my truck and I have since done my son's truck. I do recommend this pump to anyone and it comes with the old and new style gauge fittings.
Thank you,
Kenneth

Works for my casting projects Apr 13, 2009
By Adam Smith
I bought this to de-gas small amounts of silicone and polyurethane casting components, for which it performs adequately. The key is small amounds (less than a quart). For a vacuum chamber any larger than a volleball, I would look to a higher CFM pump.
