For this job, we installed a Weather King 3 ton full system with a return plenum. Replaced the drain pan and added drain safeties. Reattached the flue, drain and gas with new piping, ensuring that there are no leaks. Added two 10 inch returns to the bedrooms and reattached ductwork that had fallen off. Replaced the outdoor pad, as well as the whip and disconnect. We brazed, leak tested, vacuumed and charged to manufacturer specifications. Tested that both heating and cooling modes work and completed the walkthrough with the customer.
