Pure Air Serial Numbers 0120123 - NLT218 - 9880 0011024 - NLT218 - 1134 Notes: returned to reseal plenum and immediate ducts for the upstairs unit. Once sealed I installed a pure air x in both air handler cabinets. Wiped down biogrowth inside cabinets and supply vents. 2 bedroom vents have some rust / biogrowth that is hard to get between the fins. Summary: both blower wheel assembly’s have some drywall dust. Once projects are completed I suggest a pull and clean on each unit. Performed a clean in place on both evaporator coils. Cleared and flushed both drain lines. Gathered delta t. Left both systems in the off position. Collected signatures and payment. This job has been completed. Thank you for choosing Total Air!
