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.
yes electricity costs money and you will save it
no ! ................
Yes but a much smaller amount due to the fact that the ac unit is connected to the energy source and must stay on in order to process your request to turn the air on and off.
Throughout the world the system used for home electrification is alternating current (AC).
AC, or alternating current.
Yes an inverter AC can save electricity. Most AC motors require large amount of current to start up. Once started - they consume very little power. In traditional AC's the compressor runs at full capacity till the desired temperature is reached and then it switches off. Each time it starts - it pulls is a lot of current - which wastes energy. In an inverter AC - the compressor never turns off compeletely. It mainatains the temperature by reducing the amount of comperssion in the comperssor in real time. It sounds counter intutive that a motor but a motor running continusly will draw in les spwoer than one that keeps turning on and off. This is why most escalators in malls will not switch off instalntly if no one is using them - since its cheaper to run them rather than star/stop for short periods of time.
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.
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).
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 /
Possible low freon.
well, you 'bypass' it by turning it off? The compressor freewheels when the HVAC is off, so you might further explain bypass.
Electricity or rather electric currant can be either AC or DC. AC means alternating current (as in that electricity that is supplied by the mains) and DC means direct current (as in that electricity supplied by a battery)..
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
You have to have the motor running as well as the AC compressor turning (AC on) to circulate the freon through the system
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.
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.
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.
