Arrived to remedy a couple leaking drains and install some locking refrigerant caps. Cut away the drain stub for the upstairs unit. Made sure the drain port was clear of debris. Repaird the portion that was cut. Poured a bucket of water down the condensation drain line while running the shop vac where the drain ended to ensure any restrictions have been cleared. For the drain in the basement applied thread tape for the fitting that goes into the protrusion for the evaporator coil. Found that the end of the drain hose was smashed into place by a couple screws. These screws were causing a restriction. Reworked the drain in the basement. Systems are draining properly at this time. Grabbed some locking refrigerant caps and applied them to the condensers.
