Checked operations of minisplit system.
Return to diagnose excessive vibration from air handler during cooling operation. Made minor adjustment to airflow to partially remove the resonant frequency causing excessive vibration. Unit will need to be lifted to get vibration pads installed under the equipment. In doing so, will need to replace the drain pan as well.
Replaced one air filter, other was wrong size. Checked both mini split systems. Turned all thermostats to cool and to 64 degrees, all systems came on and ran correctly. All electrical systems are found within manufacturers specs. Temperature splits were all correct. Systems are operating correctly at this time.
Performed heating maintenance on oil furnace.
