HVAC call. Customer reports not all areas receiving AC/Air. Tested each damper for power and operation. Found a few dampers seized and manually opened. Once air flow went to the trunks that were closed off the temp began to improve in the warm spots. Used the manual dampers at the end of each trunk to balance the air flow based on user preference for the area the diffuser was cooling. The space came down to 70 deg after I made adjustments. Ill follow up on Tuesday and if any areas need minor adjustments ill make them at that point. Call is complete.
