Service eval for odor Green and blue lights off on the UV ballast on arrival. Switch was “on”. Reset switch and system turned on and is running fine. Spoke to dynamic AQS rep as that failure is not listed in their paperwork. Was advised likely due to loose connection on the UV system particularly the ground wire Tightened all wire connections and redid the ground wire with a spade mount Replaced electrostatic filter media due to dust build up Advised homeowner on difference between soft and hard start kits to prevent lights flickering when condenser turns on System cooling at exit
