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

Question

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.

thanks guys good to know Im not the only one. we have done everything like suggested. on the cooking thing I told my husband that because of the heat we need to eat out more often(ha ha).

Answer 1

Yes, that's normal. I am here in georgia, have the ac on 78 and it runs all day before shutting off

Answer 2

First off
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.

Answer 3

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.

Answer 4

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.

Answer 5

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.

Answer 6

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.

Answer 7

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.

Answer 8

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.

Answer 9

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.

Answer 10

properly for one element i do no longer see it as Gates vs. GM yet I see it as Ford vs GM in that Ford while he had to make money put in all of the robots on his production line and now has different technologies, the laptop, as properly. this is often while somebody desires to make greater money than they have already got that keeps human beings out of artwork. technologies has this is solid factors as properly as undesirable. i'm uncertain if that equals out nonetheless on the grounds that there is too lots blazing and blasting and tormenting and following as properly as too many bored technologies human beings stepping into places they might desire to no longer be and stealing education, spinning it and protecting the international on ingredient. easily i'm fearful of #8 using fact I stay in a community the place there's a lot of water. i'd would desire to apply a variety of element-a-ma-jiggers and smack my front window to get out of my vehicle if I landed in a lake or in tornado or typhoon water. Plus those computerized homestead windows can seize a individual's long hair and rip off their hair and you will choose a lot of stitched interior the emergency room. even with the undeniable fact that i recognize technologies continuously asks me "do you rather decide to try this" any time i choose something achieved on the laptop even with the undeniable fact that this is great disconcerting using fact i became into reported working with legal specialists in that in case you will desire to ask them a query two times in basic terms inquiring for confirmation they brissle or get indignant or assist you recognize off and you ought to get fired so my reaction to my laptop asking me "do you rather decide to try this" is in a screaming tone I respond "I specific as H do". grrr. All i recognize is that there is a vehicle maker accessible insisting on making a vehicle for the blind to force. So according to hazard technologies has reached its limits.
