During set up for duct cleaning it was noticed that there was no access to attach the vacuum hose to the supply trunk. The unit has an open return. At this time we are not able to properly clean the duct system. Management was notified of the situation and it’s recommended that a 16x16 access panel be installed above the air handler. Once the access panel is installed a proper duct cleaning can be conducted. Please reschedule once the access panel is finished.
