I came to do a prepaid ac tune up. There is a water leak at the inside unit. We need to redo the pvc drain line. The humidifier is leaking and needs a new pad. They do not have a wet switch. The filter is dirty. Today I did an ac tune up. I changed the filter. I put one of there humidifier pads in for them. I teflon taped the fitting leaking at furnace. They did not want a wet switch today. The ac is ready to run this summer.
