    I believe that I have a leak in my evaporator coil in attic as it freezes up. I have a set of gauges that my dad gave me and I want to check my lennox system. I'm to broke right now to get the leak fixed and want to add some R22 if it is low until I can afford to get it fixed correctly. Can someone explain to me how to use the gauges before I call a service man to fix my problem.Thanks in advance.
