I thought maybe I heard the radio wrong, but found it on NOAA ($2 for a
report). Fortunately I was on a jet from SNA to ORD (Chicago) by then:
Latitude:, 33° 41'
Longitude:, -117° 52'
Station Elev. (ft):, 49 (not far from the sea)
Time Conversion:, +8
Station (Type; Name, State):, ASOS; "SANTA ANA, CA"
1553, , 36.1, -2.8, 16.2, 8 ,29.75,6,012 , .00
ie, 3:53PM 36.1C (97F), -2.8C dew pt, 16.2C wet bulb, 8% rel humidity
Note that this was after it was 31.1C, 36% 9/4, and 23.9C, 55% 9/3.
Thank you all for the replies. Now I understrand that the new AC works
well above it is supposed to do. I will ask my parents to run the fan
And I am glad to answer some of the questions ...
My mom is a patient who is sensitive to low humidity. She doesn't feel
comfortable with 20 RH as others usually do.
The humidity is measured by a digital meter which is in one of the
bedroom. It is not the warmest part of the home, not the coolest part
either. My mom uses it all year long and it is fairly accurate. We can
see it raise quickly when we turn on her little humidifier in the
As someone suggested do measure the outdoor humidity as a check of the
calibration of your meter. I have found that meters of all kinds measuring
humidity are not very accurate, although that one should seem to be very far
off or it is really low. Sorry I don't have any really good, well proven,
ideas for a solution. I hope someone has some better ideas. I just have a
hard time imagining how it is doing it. The use of a higher speed setting
and running the fan after the compressor shuts off are at lest ideas that
the time. As the humidity level goes down, the ratio of condensation
goes way down, too! His humidity gauge is way off! High SEER systems are
less efficient at bringing down humidity due to the higher E-Coil
