Hi guys I dont know much about AC s I just moved into a place and dont want to keep calling the landlord . I thought freon was put in before i move in because he said so and it was blowing cool not like before when it was freezing over a couple weeks later it froze over again and he put more freeon .it seems to never cut over so im woried about my electric bill .
now main question when i went to check to see if it froze over again because it wasnt cooling I felt air blowing through the coils I thought it was supposed to suck through the coils
One other thing you have two copper lines a big one and a small now under normal operation shouldnt both be cold because the small one is room temperature.
Thanks in advance to anyone that takes a minute and offers your expertise

 

Welcome to the forums.

The larger line should be ice cold and the smaller one will be room temperature or slightly warmer.

The air gets passed thru the coil. The direction of air travel is based on the type of air handler. Air enters thru the return and leaves from the supply side.
