Save time by buying online and picking up items in store.There's a lot of snake oil and questionable products lining the shelves of the average auto parts store. From octane booster to VTEC fluid (ha!), it's hard to separate the genuinely useful products from the chaff. So when A/C Pro sent me a few canisters of its do-it-yourself air conditioning recharge system, I was a bit skeptical. The idea is that most aging car air conditioning systems that don't blow as cold as they should suffer only from low levels of refrigerant. The way A/C Pro works is that you plug a can into your car's air conditioner and simply refill the system with R-134a refrigerant and the necessary lubricants to rejuvenate aging seals and moving parts. I've laid out detailed instructions for using the A/C Pro product in the gallery below. Check it out for photos and a full walkthrough.

Putting it to the test With the car running and the air conditioning system powered on, I located the air conditioner's low side connection port. Air conditioning systems are essentially split into two parts, the low- and high-pressure sides, and the cooling happens as the refrigerant is compressed and passes from a state of high pressure to low pressure. After locating the low-pressure connection point, I used the A/C Pro's gauge to measure the pressure of the system. (Be sure to keep your hands clear of moving parts; I got a nice friction burn on the back of my hand from a moving accessory belt.) If the pressure looks low, then it's time to refill and recharge the system using the A/C Pro product by pulling the trigger on the filler nozzle. The filler nozzle and pressure gauge combo gives feedback and control over the refilling and the user should take care not to overfill the system, which can adversely affect the system's ability to chill air. Our test car, a 1999 Toyota Corolla, was blowing 84-degrees-Fahrenheit air at the beginning of the test.

I saw a 20-degree drop in vent air temperature to about 64 degrees. That's a big-enough jump to prove that the product does work -- at least as a short-term fix. how much is a central ac unitSystems with moderate to large leaks could eventually depressurize again and may still need a mechanic's help. national ac unitA/C Pro tells us that for the vast majority of systems, this simple recharge should be enough.best air conditioner units for home All in, prepping, measuring, and recharging the system took me about 30 minutes. However, the Corolla's pressure levels were exceptionally low and I took more time than I probably needed to measure air temperatures and take photos, so it's still a fairly quick fix. I should note that the Corolla was actually my second attempt to test the A/C Pro product.

My first attempt was under the hood of a 1990s vintage Volkswagen Jetta. Unfortunately, this system had bigger problems than the A/C Pro product could fix. There's only so much that a simple refilling, recharging, and lubricating product can do. If there's physical damage (such as a seized compressor or a serious leak), you may need more help than A/C Pro can supply. Still, for only about $45 to $50 at your local auto parts retailer, A/C Pro isn't a bad DIY first step before calling in a professional (and potentially expensive) mechanic.

After using a couple of cheaper brands of sealants and recharging the refrigerant 2 or 3 times in the past to no avail, I decided to buy and try the Super Seal. I followed the detailed directions to the letter; and the air conditioner worked ok for about 1 1/2 weeks but then went kaput again. The previous attempts at sealing the system may have interfered with the efficacy of this product. My neighbor, who is a certified HVAC technician, told me has had good luck with this company's products in other refrigeration applications. In my opinion, it's worth spending the money on a can of this stuff and trying it before spending "big money" to get your auto air repaired.

That's fine, it's within expected limitations, but he bottom line is it didn't fix my... We followed the directions exactly as they are written and we no longer have a freon leak!
