Best Air Conditioning Leak Detection Tools

Inficon 718-202-G1 Gas Mate Combustible Gas Leak Detector
INFICON raises the bar on combustible gas detectors with the next-generation GAS-Mate, the ideal tool (or locating leaks in combustion appliances, such as natural gas or propane-fired heating systems, or gas valves, regulators and pipelines.
"I originally used a gas rated teflon tape on all of my joints, however I came to find out through watching my meter that I was losing a very small amount of gas somewhere in the re-piped lines. This worked well when when I had considerably large leaks, and you can easily see all areas of the joint (back side of elbow and unions), but for micro leaks the soap and bubbles didn't work for me at my typical natural gas pressure (1/2psi or less). If you planning to re-pipe natural gas line, or you have some natural gas lines in your home that you want to check to be sure, this is a great product."
"Using the Gas Mate I was able to pinpoint the source of the leak to a particular fitting, The detector lit up like a Christmas tree even though it was very hard to detect with soap water."
"This was great found my gas leak in my RV. After I fixed it I use the most sensitive setting and found a bad connection that I may not have found."
"One thing I don't like is that it will produce a continuous tone while it is warming up (which can take 10-30 seconds depending on temperature)."
"I used the gas company $3000 hand held meter, which also failed to find the same leak."
"I love this Gas Mate, I have used it on my water heater,pool heater and my RV."
"Just 34 ppm of methane that came out of the pressure regulator vent sent the the Inficon's led readout to max! The pressure regulator venting "leak" can be normal when the climate temperature is fluctuating if your gas company does not periodically adjust line pressure throughout the year. If you smell or detect gas from there, you should also call your local gas company just to have them check it out."
"I can't smell gas well enough to locate it - this device is exactly like the pros use and it is accurate, easy to use and just saved me a lot of investigative hassle trying to find and then determine I had fixed the leak."
