Service call for 1st fl system not working properly this is space pak unit located down in the basement with a daikin outdoor condenser. On arrival system was turned on and all operations were checked. Checked drain line to ensure it was not clogged and poured water to test condensate pump. Found air filter very dirty 20x25x4 I put a temporary air filter 20x25x1. checked refrigerant pressures after replacing filter and pressures are ok. Very possible that the clogged air filter could have caused some issues. A maintenance is recommended customer is going to have us come in the spring time to complete tune ups on both systems. System is currently operational. https://visionshare.xoi.io/?id=msc0553b4e-575d-i184-6e5842bc82a1-uF83-5427b1155cef
