When setting your thermostat for heating and cooling which is the least expensive setting, "auto" or "on"?

Answer 1

Auto and set your thermostat to 78 degrees or higher if you can stand it.

Answer 2

Set to Automatic at a comfy tempature for you, and animals, and parents, inllaws, travelling salesman, plumber, auto technichian, and whatnot.
I rekon 78-80 is survuiveable, set it and lock that unit up. Where all the crazy billing comes , besides the use of oil and junk, is from constant adjustments that are very uneeded. If a human can survive and did with out Enviroment Controll for a buncha thousunds of years I think we can make it though one lifesapan without the comfort of no sweat and no chills. Gets really goofy when the sweats come in the cold outdoors. And visa versa.
If you have so many monies to have Central HVAC then why worry?
Folks all over America dont even have a house, they is the houseless ones that dont work so should be in jail, but thats another topic.
The housless peoples seem to endure it ok, but yeah, one tempature year round and leave it be is best way to save expenditures on a thingy like that.

This basically depends upon the home and climate you are in. The AC unit has two basic components, the cooling/heating component (furnance, compressor, evaporator, condensor, etc.) and the air flow component (fan, ducts, etc.). When you select 'Auto' this tells the system to only activate when the temperature rises or falls above a given set point. This setting turns on both components.

When you select 'On' the tells the system to run the 'air flow' component constant and it will cycle the temperature component as needed. This setting is good for places where circulation of the air is conductive to good temperature control or for air filtration for those with high allergy problem or if the home uses and 'complete home air filtration system'.

Obviously running the fan constantly is not the most efficient in most cases. The auto setting is the best.

Hope this helps!

"On" runs your A/C constantly. "Auto" runs your A/C until the programed temp is reached and then it shuts off... It will turn on again to cool the home if the temp rises above the programmed temp.

Cheapest is "auto", to save even more money and electricity set the temp 3 degrees warmer than what your ideal temp is during the summer and 3 degrees cooler in the winter.

If you don't have children or pets that are home during the day turn the A/C off all together and then turn the "Auto" on when you get home.... You'll save a bundle!

Answer 5

Auto or on only applies to the fan. It should always be set to auto, unless you just want to circulate the air in your house. It will not affect heating and cooling cycles.

Answer 6

If you set the fan to "on" it will run 24 hrs a day. If it's on "auto" it runs only when the heat or cooling is on

Answer 7

set it on auto. if you set it to on the fan will run continuesly driving you light bill throught the roof. also try to leave it at one temperature setting when you are home. 74-75 is usually adequate. then push it up to 77-78 when you leave, but do not shut it off when you are not home. It takes more energy to cool a house down when the /c has been off all day, than it does to keep it at a constant temperature.

Answer 8

It depends on where you live for the proper temperature setting, but always leave it in the "Auto" position. Leaving it on "On" will make the blower motor in your air handler run all the time, not the compressor, therefore its more expensive. To cut cooling costs, make sure your a/c filter is clean. A clogged air filter will restrict air flow to your system.

Answer 9

Auto. On is just constently running, where as auto all runs when the temperature drops or rises above what it is set to.

Answer 10

It would be least expensive to put it on auto, that way it will kick on when your house gets to warm instead of being on all the time.
