Perform single system heating maintenance. The system was installed in 2023. It is a communicating heat pump. I checked amps, filter, electrical, thermostat and temperature differential. The system is heating inside of manufacture specifications. I ran air advice machine to test the air quality of the home. I spoke to the customer to see if they are interested with adding the air scrubber the their system and uv stick inside their evaporator coil compartment to help prevent possible growth in their air handler. The customer is not interested in the Airscrubber and Uv bundle at this time due to other projects. A price for the IAQ bundle was requested for future reference. Unit was back to cooling upon departure
