Arrived on site for freezing coils in air handler. Upon arrival and handler was completely thawed. Went to go check pressures on the unit and pressure seems fine. Temperature difference inside the house peaked at 18° difference. Static pressures inside the house was good. All vents were open all dampers were open. Went to check the DATS and noticed there isnt any, told customer we'll come back to install discharge air temperature sensor. Customer acknowledged, paid, and signed off.
