I live in s.c. its 107degrees,my a/c has not shut off,is this normal?

I have a 28X68 mobile home, with central a/c and its set at 70 degrees. it didnt shut off until 10pm last night. I change the filters regular.

I live in s.c. its 107degrees,my a/c has not shut off,is this normal?
Yes, that's normal. I am here in georgia, have the ac on 78 and it runs all day before shutting off
Reply:Most A/C systems are designed for a 20-25 degree difference in temperature. If it is 100 degrees outside and inside is 75 degrees it's doing the job. Yes, its normal.
Reply:There isn't an ac made that was designed to maintain 70deg in the summer. You need to get use to a higher setting. Keep raising the thermostat until it cycles once and a while.
Reply:At 107 degrees on a mobile home and with any humidity , it would not be unusal for your a/c to run well past midnight, you might want to clean the evapartor and condenser for maxium efficiency though.


Also make sure that your condensate drain line is not blocked by mold or algae.





Just remember its like your fridge keep the doors closed as much as possible that will help a lot at that temp.

70 is to darn cold to be keeping your house in summer. Actually 70 is borderline freezing up your AC anyway. you should be running a coil temp above 40 F if the room is 70 and you have a 25degree temp drop the air coming out of your coil is 45 degrees which puts your coil about 35-38 ...thats too close to freezing . ANY problems will cause the coil to freeeze up and stop cooling alltogether. ALSO PLEASE


NOTE: Setting the thermostat to a colder temp will NOT make the AC cool more. It only lowers the temp the AC cuts off at. If your rooom starts off at 90 and you want to get to 78 setting at 78 will do it as fast as setting it at 70. the Temps below 70 are for HEATING not cooling. I advise people to set cooling temps at 78 and heating temps at 68


100 degrees out side you should be around 78 in the house . other wise it can make you sick..


NOW back to the question


YES its normal. Mobile homes are notorious for being hard to cool , not to mention many installers undersize the AC units. OR at leas sized it for more normal temps there.


when the temps outside get over 100 its harder on teh AC to do its job to begin with, and also the heat load on the house goes up. So you have 2 limiting factors on it.


To save some money try setting it to 78 and run a fan. also you can get a water hose and wash out the coils on the outside part of your AC . that is what condenses the freon back to a liquid and removes the heat from your house in the process. If that coil is dirty its less efficient and the AC has to work harder.
Reply:A properly sized AC unit should run almost continuously on the hottest day of the year to keep the inside at a comfortable temperature. If it is only running part time on the hottest day of the year, then it won't be running enough on cooler days to properly dehumidify your home. Of course if it is running full time on the hottest day of the year and you still aren't comfortable then there is a problem.
Reply:I have the same problem with my mobile home in California's Central Valley. It is normal. And be glad you don't live in Blythe, CA. It was 127 when I was there.
Reply:Unfortunately, I live in SC too and I am also dealing with this outrageous heat. My A/C is working overtime too. Best thing you can do is cut down on oven usage and long hot showers because they heat up the house and don't leave the door open long when going in and out.
Reply:Its 107 here also in Alabama. My ac has not shut off because


it is thermostat controlled. That means that it much reach, consistantly cool, and maintain a temperature of say, 78. Because it is so much warmer outside, It must work much harder to reach and keep that temp throughout. So it is staying on much longer than normal.
