For this job I did a super tune up. Deltas are good. Drains testing clear. Changed filters. Furnace components are good. Recommend pulling and cleaning blowers due to extreme dirt build up. Recommend replacing thermostats as they aren't intuitive and the buttons don't always register when you click. Outdoors refrigerant is good. Running amps are good. Cap and start kits are good. Cleaned coils. Recommend unit surge protection. Recommend replacing disconnects. Homeowner would like time to decide on work to be done. Systems cooling when I left.
