Arrived on site, located store manager. Store manager directed me to units, two units are in a HVAC room/closet and the one rooftop unit( not on the rooftop) is located behind a store. Who was informed rooftop unit having four filters, it has six, two of the filters that need to be changed are going to be in front as soon as you pop off the panel to access filters, the rest of the four that are behind them are new. The units inside of HVAC room those two filters have been changed.
