Upon arrival for super tuneup I found that home has two units but call was only scheduled for one so I asked homeowner if he wanted both units serviced to which he replied that he did want both. I called the office for them to correct. I asked homeowner for filters to which he replied that he wasn't sure if he had any that he would have to look for them. Homeowner showed me to attic access and upstairs thermostat Homeowner also mentioned that he had a water leak from the unit causing a leak on his ceiling in one of the bedrooms and asked for me to take a look at it. I began with the indoor unit for downstairs where I found water built up in the pan and the pan leaning to the left causing water buildup to drip over and leak onto drywall. I found cause to be a slow draining primary line causing water to come out of secondary into drain pan I then checked delta for unit and it was cooling at 20° Checked blower motor which was a little dirty but in good condition Checked Evaporator coil
