In Gilbert Arizona, I completed a scheduled maintenance on a Daikin split heat pump. I checked indoor temperature splits, indoor airflow, indoor motor amp draw‘s, capacitors, I checked rinsed and flushed the drain line. The drain has a blowout valve which I use nitrogen to blow through the line. I informed John of adding a start assist kit down the road as it helps the compressor on start up which should allow the compressor to last longer. Thank you for choosing Hobaica!
