I was called out to Michael’s house for a Homecare maintenance. Michael has lived here for awhile so we performed a thorough evaluation. During the evaluation we discovered that the systems need their flood protection updated, the plenums are duct board, the filter racks are outdated and 2 of them don’t work, and the basement air handler needs a uv to keep it clean internally. Today I added some refrigerant to the main and basement systems and I adjusted the airflow for the main and upstairs system for better efficiency.
