Homeowner agreed to sign up both systems for our homecare membership; 26.95$ per month for 12 months. Performed 2 system homecares. Emailed estimates for updated flood protection, install a bypass and to add refrigerant to AC systems. Both heating and AC systems were operating at the end of service call. Issues: Both systems needed updated flood protection; builder installed very cheap unreliable flood protection. Both systems are low on refrigerant; refrigerant is needed so the systems can cool and dehumidify the home properly and to prevent the systems from failing. The upstairs system needs a bypass installed for the zoning system to decrease pressure on the system and to prevents system failure. I flushed the drain lines with water; media filters are ok for now. I believe that installers didn’t add additional refrigerant; leak reach maybe needed in the future if AC systems become low again.
