Question bro never worked on big boy stuff like that just got into a light commercial company so since their are 2 circuits did you have to recover the refrigerant on both circuits in order to change out this coil ? And vacuum and charge each circuit individually?
Yep, each circuit must be recovered, filter driers changed, vacuum pulled and recharged. Every now and again on larger systems you’ll run across parallel compressors and then you only have to recover one single charge for a large coil even though there are multiple stages. Also some of the larger Lennox’s are going away with the multiple circuits on a single coil and they’ll send you two individual coils to replace the old single coil.
Good job bro
