Which is cheaper to run? The air conditioner or dehumidifier?

since indoors here for at least 4 months during the year it's 83 indoors average, I can't understand that you'd have 68 indoors or even have it all day without having a huge electric bill. Are you renting that your electric payment is within your rent?

I don't use a dehumidifier here. I do use a fan in the bathroom though for drying out after showering. Sure you need to have the air circulating so that your place won't mold but I've never in my life used a dehumidifier. Doesn't a dehumidifier dry you (and your wood furniture) out? And since you said yours is a portable are you saying it's a window AC because if so there might be a security issue. I always thought a dehumidifier was for a person who has asthma.

An air conditioner and dehumidifier are the same thing. The only difference is that the AC will dump the warm air it generates outside of the house. In the summertime running a dehumidifier strictly for dehumidification, when you still need cooling, is a fool's errand. You could be availing yourself of the cooling too.

Air conditioners -by nature of how they work- also dehumidify the air. However, a dehumidifier is not vented to the outside so will generate heat. This heat comes from the compressor and fan motor. In most cases, you are better off using an air conditioner to not only dehumidify the air but also expel the waste heat outdoors.

Dehumidifier

A dehumidifier. But only because a dehumidifier's function is to remove water from the air while an AC unit's function is to cool the air; a side effect of an AC unit does remove water from the air.

A dehumidifier.

It simply depends on the watts of the unit itself. A dehumidifier that is rated for 1500 watts uses the same amount of power as a AC unit rated at 1500 watts. They are basically the same except one dumps heat and water outside and the other just dumps water into a bucket or down a drain.

Thanks Bob for the fast answer. I hope I get others because on research the answers are all over the board. Dumb me never thought about using the dehumidifier during the day before now after 10 years of running it.

Probaly the dehumidifier

Dehumidifier.

But they don't do the same things (although both do have the effect of reducing humidity).
