Arrived on site to perform spring tune up on 2 2 year old unit. Client stated no issues as units are new. Cycled both and both operational. Washed both condenser coils inside and out. Primary starter good. Secondary motor control is good. Both fan motor are good and in range. Checked start up and run amps on both. Heat pump is holding good charge and cooling at 19 degrees. Mini split is cooling at 2 degrees. Found no protection from n either u it and highly recommend adding protection to protect systems from electrical surges and power outages that can damage or even short out systems and components. Inspected in door unit. Filter was dirty and replaced. Coil was good and motors as well. Ducting is new and good. No protection on indoor unit and recommended adding some to protect systems. Cycled units and went over all findings with client and she is aware how unit is running and cooling. Client did hold of on recommendations but did renew ESA. Both units are operational upon departure
