A few years ago I purchased a new home. This year I decided to hire an
HVAC service firm to get my HVAC serviced/checked. Given I'm new to
all of this, I don't know what is "normal" service.

Is the following considered normal service? I'm asking because I want
to get a better sense of whether or not I should hire this firm again
next year. This is what they did and didn't do.

1. checked the inside unit: electronics. This did not include looking
at the evaporator coil to see if it needed to be cleaned, and it did
not include removing the blower fan to visually inspect it or clean it.
He simply put his finger into the blower fan, said it looked clean,
and left it at that. They indicated that cleaning the evaporator coil
was an extra service that I would have to get a separate estimate for.
He indicated that it was likely clean, and that it would not need to be
cleaned until maybe after 7 years of service. He said they needed to
put a chemical on it to clean it, which is why it was a different
service.

2. outside, he checked the compressor unit. He checked the Puron
level, and added a bit. He also checked the outside electronics. Last,
using a hose, he washed down the inside and outside of the unit
including the fins.

This cost $99. I live in California if that helps with the prices.

Is this normal servicing?

How can I personally check if the condensor coil is clean?

Thanks,

Jack
