Upon my arrival in Austin, I performed A/C cooling evaluations on all systems except the Carrier mini split. Found all newer systems running and operating properly at this time. Replaced all air filters in the home. Found the air movement system in the highest attic with the Lennox system to be very dirty, I recommend having the indoor air movement system cleaned. The amp draw on the refrigerant pumping station is also almost at the very maximum amp draw on the system. I would recommend having a system consultation before we run into further issues with the system. Client would potentially like to set the mini split up on a maintenance plan as well.
