What temperature should I be receiving from my vents when it is 100 degrees outside?

yup and is cooling just fine.

Will run same tests tomorrow during the day.
I normally only get 12-13 difference when it is hotter outside and in the attic.
Tomorrow will be the first time I check it right after the coil though.

1 degree gain is kind of ok. On a system moving 1200 CFM, that would be just a little over 1200 BTUs gained.

Time to clean coils and check SH and SC.

Ok thanks.

Both coils are definitely clean.

Can you explain how I would check the SH and SC?

THanks

At this point you need to call a tech to hook up the gauge and check the pressures and temperatures

I am thinking my outside unit is running too hot.
It seems to be a good bit hotter than most others I have felt.

How would I check the amperage on the fan motor and compressor?

thanks
