RE: Do we change filter driers on units that have them inside the condenser?


Hey guys

My employer is a lennox dealer and unfortunately on some of the units  they come with driers on the inside of the condenser. Do we have to change them if we are doing a pump down and swapping the evap or txv.

If the charge is out of the system, I think it’s best practice to replace the drier. In that case, I would also relocate it.
