Arrived on site to perform cooling maintenance on newer install Lennox package unit. Upon arrival, the cleaner said she has been running it all day but it would not go below 81 degrees in the home. I checked the filters and set the thermostat into cooling. I went to the unit and checked indoor coil, blower assembly, electrical connections, capacitor readings, temperature split, refrigerant levels, and amp draws. No issues were found. I then went inside and checked the supply temp of 4 different vents. Found they were pushing out about the same temperature as the all the other supply vents. Explained to contact that it is about 105 degrees outside and manufactured homes don’t have the best insulation. It is going to work harder to get it cooler as the temperature outside increases. No issues were found during this maintenance. Unit is cooling properly at this time. All work is complete
