Today I arrived on a service called and notice unit had a restriction airflow causing the compressor to struggle to pump refrigerant also its low on refrigerant. Club member needs and blower wheel cleaning and evaporator coil cleaning. Club member is aware of the situation a wants to be on maintenance next week morning what Lauri prefers.
Service fee unit wasn’t operating and it needs components to get the unit back operational
Arrived to thermostat set at 68 reading 76. Ensured blower is operating. Checked refrigerant pressures and found mini split was slightly low on R410A. Added 5oz of R410A to make refrigerant pressures and temperatures appropriate for indoor and outdoor weather conditions. Checked for leaks none found. System is cooling at this time. Temperature split 20*. Return air 75*. Photos attached.
DCM1: AC complete. Checked 16x25x4 filter, filter is dirty recommend replacing to keep system clean and increase longevity of system. Spoke with homeowner he decided he was going to order one. System is fully functional and operating within manufacturer specifications. Refrigerant pressures and temperatures are appropriate for indoor and outdoor weather conditions. Maintenance checklist attached.

Maintenance checklist attached. Arrived to thermostat off and indoor temp 45*. Turned system on heat mode, system turned on however was not heating. Checked indoor and outdoor control boards for codes, board was not flashing codes. Checked refrigerant pressures and temperatures found that mini split is low on R410A, reached out to manufacturer to see if system is under warranty however they are closed today. Need to let homeowners know if system is under warranty or not and options from there.
