air conditioning?

Question

ok my brother said that if the air conditioning for my house runs its a waste of electricity but i want to prove him wrong cuz its hot as **** in the house. i want facts to prove that having the thing trun on and off like every 10 mins is more waste of electricity than rather just let it run

Answer 1

It is true. If it keeps coming on and turning off it will cost more money on your electric bill. It takes more electric to keep starting the condenser and evaporator.

Answer 2

If the unit does not run, it is not using electricity. When the unit runs, as it first starts up, it draws a little more amperage to get the motor started, then it goes back to its running amperage. This takes less than 2 seconds. You use more energy by constant draw than by resting for 5 to 10 minute intervals.

If your AC is constantly running, you have either too much heat for the unit to remove, the unit is inefficient, or undersized for the application.

With the AC on, take a good thermometer and put it by the return duct (air going back to the air handler). When you get a good reading, go to the supply duct (air coming out of the system) and take a reading there. Ideally you want a 20* difference. If it is less than 16 or more than 22, you have an issue that needs to be addressed professionally.

Your system will use less current if it is allowed to cycle as it removes the heat in your home. Of course, if you live in a high-humidity area and have a lot of solar gain during the day, it will run constantly to keep up with the heat load. Look at insulating your attic, and planting deciduous trees on the south.

Answer 3

A waste of energy is in the eye of the beholder. If he hates ac its a waste. If you love, it it's not. The only exception would be if you keep it too cold.

Answer 4

once you plug it in it starts more elctricity when you leavre it on it just runs !
