For this job I did a super tune up. Deltas are good. Homeowner said he will replace filter himself. Drain testing clear. UV bulb is out, homeowner expressed he was upset about previous explanations, tried to clarify. Furnace components are good. Tightened electrical connections. Outdoors refrigerant is good. Running amps are good. Home has solar battery, recommend soft start to drop amp draw on startup below 35. Washed coil. Recommend surge protection for unit/home. System off when I left.
