    Hello I have a question. If there are supply leaks outside the thermal envelope will it pressurize the house ? And if there are return leaks outside the thermal envelope will the house be depressurized ? I’ve been study for my Raters exam and this was on one of my study sheets .. I feel these are wrong and it’s vice versa actually. Thanks I would appreciate the help

    Be careful - the scenarios we talk about in this video are about air movement when in the testing conditions only - this is not about standard operations.
