Perform seasonal maintenance on two split systems and a mini split. Systems running within manufacturer specifications. They all had good temperature differentials and found no issues with system. We had recommended on one of our last visits to do a leak search because I suspected there was a leak, they had their home warranty, come out and do the work on that. However, I did leave estimates for a condensation safety switch on both units and a in rush device. Homeowner said she will talk to her husband about installing the condensation switches, but did tell me to go ahead and install the inrush devices today. All units running at departure.
