Preformed dryer vent cleaning. Preformed 2 system heating maintenance on 2018 gas furnaces. I tested all electrical components and safeties on both units. All electrical components and safeties tested within manufacturer specifications. I did find that unit number 1 ducts were dirty, also both units did not have float switches on them along with blow out valves. I presented client with findings. Client would like to hold off for now. I noticed when visually inspecting the outside unit that the suction line was not getting as cold as I would like to see. I proceeded to take a temperature reading of unit number 1s supply temp. I was getting around 58 degrees. Client would like refrigerant levels checked during their next visit. Client did not have filters to change out at this time 20x25x4. Unit was cooling upon departure.
