Question about my Maytag 8000BTU A/C
Good golly it is hot!!!!
Having said that, I am concerned that my 2-year-old Maytag 8000BTU A/C
should be doing a better job than it is.
I have it in my 12' X 18' so-called sun-room. The blinds are all
shut. We were away for several days, and of course the room was quite
hot when we returned.
I put the A/C on High Cool, but after some 3 hours the room temp is
still some 84 degrees. I put a reefer thermometer in the outlet of
the unit, and it reads about 65 degrees at the lowest. No wonder the
room stays hot. Shouldn't the 65 degree-reading be lower - say, 50-55
I do hear the compressor cycling.
What is the outdoor temperature? A 20 degree drop over the coils is about
right. With the recent very high temperature we've been having in most of
hte US, you won't get the same cooking you got last year when the outdoor
temperature was 15 to 25 degree less.
My question though, is the compressor cycling. Do you mean it turns off
and on? Seems to me at 84 degrees, it should stay on for some time. Is
the filter clean? Coils clean?
Thanks for response.
It was 100 degrees here yesterday, which is quite high.
No, it was not cycling much if at all. I can set the threshold to
make it cycle. Yes the filter is clean as are the coils. I checked.
It just surprised me that the temp of the air coming from the thing
was as high as it was. My RV's roof A/C, for example, puts out air so
cold that it has a 'bite'. Much less than 65 degrees. Same is true
of both of my auto A/C's.
This AM, the ambient air outside is in the 80's. I want to see how it
behaves this morning (it was off overnight).
This shows what a central unit air temperature should be. I don't know about
a room unit.
I do know that the auto AC is very high capacity and the leaving air
temperature is lower than a residential unit.
You may do better overall leaving hte AC on overnight too. The solar heat
gain may be more than the capacity so running at night reduces the sensible
heat to start out the next day.
What does anyone think?
Room units usually have two or three fan speeds.
Does it feel humid in your home?
Try medium speed for several hours for a cooler cooling coil.
If you have acute humidity problems, try low speed for a umber of hours.
Buy a thermometer that also reads percent of humidity and try for 50% or
After things cool down:
Give it 24 hours.
Approx 15-20 difference between the air temp in and the air temp out is
normal for the 8,000 BTU unit.

I feel better now - even if I am hot.
