Surge Protector Completed full maintenance on split system unit Checked refrigerant levels and temperature Tested capacitor Tested fan and compressor amps Vacuumed and flush condensate line Took temperature splits from supply and return Tested blower wheel amps Tested float switch Checked UV light Unit is up and operating at this time Customer approved of the installation of a surge protector. I went ahead and installed it on site. Unit is still in good condition. There is a little bit of bacterial growth growing inside the air handler cabinet. She has a UV light in the supply duct. If she wanted to go above and beyond I recommend installing the 24 V UV light in the air handler cabinet to eliminate any bacterial growth in there
