Had an interesting discovery when trying to cool down my raptor this afternoon. I had thought that it would be a good idea to run the garage fan on high while running both the main A/C and the bed room unit. I thought that this would pull in cool air from the living area into the garage. However, after running for two hours and seeing just a few degrees difference in temperature, I started to wonder what was happening... A/C's were blowing cold why wasn't it getting cooler in the living area :confused: As I came near the bathroom step I found the issue. Apparently the fan in the garage was pulling in air from the furnace fresh air duct under the stairs and that air was as hot as the outside temp. I then shut off the fan and magically the air temp in the living area started to drop.
Has anyone noticed this issue? I am thinking that the fan in the garage is better suited to pull in air from open windows and should not be run when the A/C is running.
