Donna asks…
Do I save more energy if I turn my air conditioner on at night vs during the day?
Kind of a dumb question. But does the heat outside cause the air conditoner to work harder and use more energy?
adminsta answers:
Yes it does. Your air conditioning unit has to take air in (air intake) and the hotter the outside air, the harder it has to work to cool that air down to a desired temperature. This hot air goes into the unit, has to go through a cooling process(coils and fans and that’s where the freon comes in). This liquid/chemical is what cools the air and then this is what in turn turns into the cool air blowing inside your home. The ideal A/C system, in theory, reuses the cold air it blows out – energy efficient systems do this supposedly – through the air return, so the A/C unit does not have to cool outside hot air anymore. Some people recommend that you turn off the A/C while you’re not at home and turn it on when you come in, but that causes more energy to be used because the unit has to cool down a space that is hotter than it would be if you left it on all day. When not at home, turn it up a bit, maybe to 80 degrees or so. When at home, lower it to 77-76. A 2 degree difference from what almost everyone likes (74-75 degrees) is hardly noticeable by our body and will save a bit of energy. The night factor depends on where you live, is it a hot-humid area or a hot-arid area? Air temperature during the day vs. Night may or may not have such a big impact. In hot-humid areas, the air is so saturated with moisture, it may seem like it’s cooler at night but it really isn’t. Hope this helps.
Paul asks…
Does the energy save setting on air conditioners really save much energy?
I know it turns the fan off when the compressor isn’t running, but don’t you save more money be letting the fan run to get all the benefit of the cooled radiator of the AC. Would it help to cut down on humidity by letting the fan run?
adminsta answers:
The off position will save a lotmof energy. Other than that, not much at all.

Daniel asks…
What percentage of energy do you save for each seer your air conditioner has?
I know if you go from 13 to 15 you save twenty percent, and 15 to 17 thirteen percent, and 17 to 19 five percent and 19 to 21 five percent, but what about the rest of them?
adminsta answers:
It depends on what SEER you start with as a basis.
SEER. Seasonal Energy Efficiency Ratio.
It refers to the BTUs produced divided by the Watts used over the course of a season.
A 10 SEER produces 10BTUs/Watt
A 13 SEER produces 13BTUs/Watt
Dividing the BTUs produced by the watts used gives you the SEER.
A 10 SEER will use 30% MORE energy than a 13 SEER.
A 13 SEER will use 23% LESS energy than a 10 SEER.
The energy saved (as a percentage) by going to a higher SEER is:
[SEER(higher) minus SEER(lower)] divided by SEER(lower) all times 100.
Nancy asks…
what is the required temperature for lg air conditioners to save energy?
adminsta answers:
To save energy you turn it off. Since you have an AC that means you want comfort. With that in mind, I would set it at the highest temperature at which you are comfortable.
People all have different ideas and opinions about what is correct. The first problem with that is the fact that no two thermostats read the same temperature. They can vary by 1 to 2 degrees when them come from the factory so one person’s 75 degrees is another person’s 77 degrees.
As a matter of interest, we set our thermostat at 78 degs in the morning, 79 in the afternoon and 77 at night. That keeps the AC running enough to keep the humidity down and make us feel comfortable. If we set it at 79 all of the time, it wouldn’t run at night and the house would become very humid. If we set it at 77 all of the time, it would excessively in the morning and afternoon and make the house too cool.
