Need help installing a new a/c system
Hi . I have too install a new A/C system and between the outdoor unit and the building it's a side walk and I have to go with the piping (7/8 inch) underground for 6 feet .`
My question is if I have too put a trap for the oil ? I am 95% sure that I have too , but it's better to have others opinion too .
Thanks
