Re: New AC evaporator install
What about plain old compressed air from a bicycle or tire pump and a

Re: New AC evaporator install
What about plain old compressed air from a bicycle or tire pump and a
brush with soapy water on it to check for leaks before bolting things back up? Same as we do on a new gas line install or an under pad plumbing install final test.

Re: New AC evaporator install
Where the heck is Nathan, now that we really need him? Compressed air is
bad, because it carries moisture. Nitrogen is better, because it is dry. Professional HVAC-ers use an electronic or chemical leak detector, because a leak doesn't have to be very big, to cause problems. In other words, a leak that you might miss, with the soap bubble test, can make your system leak down in a season. There is a cheap halide detector, that you may have seen, made from a propane torch and a copper disk that is heated red hot. The flame changes color when exposed to a gas containing halides, refrigerant for example. I assume that the electronic detectors are "better". They are more expensive, anyway. Reiterating that I am a mere amateur at this, the best way to test for the presence of a leak, is to pump the system down, and verify that it can hold a vacuum, preferably for several hours. This is better than a pressure test, because a vacuum gauge will move a lot, from just a little air leaking in. If the system holds vacuum, then you are ready to put the dash back together. It is when there is a loss of vacuum, even enough to make the gauge move a smidgeon overnight, that you absolutely have to identify the source of the leak. (The idiots who worked on my Suburban could tell that something was leaking, but none of them had the presence of mind to expose the rear AC unit for inspection. Not finding a leak, is not the same as holding vacuum and having a tight system.) If you are on budget in the back yard, the best alternative might be a chemical leak detector. These come in cans, similar to refrigerant cans, and contain a mix of refrigerant and a red dye. These work best if the system is running, circulating refrigerant and oil. They are not so good for verifying that the system is tight, before you put the dash back together.
