It depends on how long you will be gone.

Assuming you have a properly sized central air conditioning unit, if you are gone for a typical 8 hour work day you will save money by turning it off when you are not at home. If you are leaving for only a couple of hours the energy savings will not be significant.

Newer thermostats have the ability to set a schedule for the AC unit so that you can have the house begin to cool a set time before you get home. This ensures you are always comfortable at home and also saves you energy.

Depends on how often you turn it on/off. Basically the longer you leave it off the more energy you'll be saving. But if you intend to turn it on/off with only minutes interval you might as well leave it on.

In North American homes this is not a policy. Many home are automated and need the power on to operate. The only thing that needs to be shut off is the hot water tank if it is electric and the thermostat should be turned down to a minimum when you go away on holidays.

With the ac off your clutch the outer non belt driven part will not be turning. When it is turned on it will start to spin.


IS more gas used with the air conditioner on?

Yes. But if you try to save gas by turning off the ac and drive with the windows open you will change the aerodynamic properties of the car so that its air resistance is higher and it will therefore use as much (or more) gas as with the ac on (and windows closed).


Why would the cooling fans for the radiator not come on a 1994 Honda Accord if the fuses look good. Even if the the ac is off?

check the relay / check the temp sensor / try turning the fan on by turning on the AC - fan should come on when the AC compresor turns on /


Why does the AC stop blowing cold air but then works fine after turning AC on and off a few times on a 1999 Express van?

Possible low freon.


Can you bypass the ac on 95 bronco?

well, you 'bypass' it by turning it off? The compressor freewheels when the HVAC is off, so you might further explain bypass.

It cant, that's a wives tale. The less the AC has to work the cheaper your energy bill.

Check for loose connection or loose fuse in fuse panel


Why doesn't my car's air conditioner blow cold air when the engine is off?

You have to have the motor running as well as the AC compressor turning (AC on) to circulate the freon through the system


Why your ac not working on your 1996 Mazda 626?

First check your fuse for your AC in your fuse box, make sure it is good. Make sure your cooling fan is turning on when you turn on your AC, if not it could be your fan relay. If the AC compressor fan clutch is kicking on and off then it just needs freon. If the AC compressor fan clutch is not turning then it could be completely out of freon due to a leak, or you need a new AC compressor.


Can an ac motor generate electricity?

An ac motor cannot generate electricity but its shaft can be coupled to that of certain devices like an alternator to in order to generate electricity.


Will turning off the AC and turning on the heater actually cool a hot engine?

Yes, the heater uses and cools hot water from the engine that would otherwise have to be cooled in the radiator. But, this only works if there is enough water to circulate. If your engine is overheating from insufficient coolant, the heater won't be much help. Turning off the air conditioner will always help. The air pulled in the front grille passes over the hot AC condenser before it gets to the engine radiator. The AC compressor also puts a load on the engine, so turning it off will make less heat in the engine.
