AC that pulls the lowest amount of electricity

Looking for recommendation for ac unit (for bedroom) that pulls the lowest amount of electricity.  Our electricity is very old & our fuses can easily be tripped.  Any recommendations?  Thanks!

Your best bet might be to ask an electrician directly?

Yes, unless someone here who is a professional who is familiar with the different brands, I wouldn't rely on the information anyone provides.  You're asking a specific technical question.  

A good bet is to do a quick Google search.  The info is out there.

If your fuses are being tripped, there are more important things to consider than the draw of an a.c. 

First of all, are they fuses or circuit breakers? Either way, if they are being tripped, that is a sign that your house AND ITS OCCUPANTS are in danger.

Call an electrician for an evaluation.

An electrician will likely tell you to upgrade your electrical service at a cost of mucho dinero.

The amperage of ac's is readily available on the internet. If you look up ac's on, you can see what the draw is for each one. It will be listed under the product specifications.

However, first you need to know how many BTU's you need so that you get a properly sized one. BTU's are dependent on room size.

Here's a btu calculator to help you figure it out.


You've stumbled into a more complex question than you thought.

Air conditioners draw a lot of current. You probably want to stick with one that has a 5000 BTU rating which should be fine unless your bedroom is a two-story loft with floor to ceiling windows. A lower BTU rating means less current.

Try to find one with an Energy Star rating. They are usually the most efficient.

But you also have some homework to do. Each manufacturer should have information on their website or a downloadable manual that will tell you what the appliance draws in terms of current.  It would be listed in amps. If you want to find the one that has the lowest operating current you'll have to look at all the manuals. I doubt you'll find someone on MOL who knows which manufacturer draws the least current.

The other problem is one that's common to a lot of older houses. There are probably lots of outlets and lights on one or two electrical circuits. It might be a 15-amp circuit. Everything plugged into that circuit draws a certain number of amps, and if it adds up to more than 15 the breaker will trip. 

You need to figure out what all is on the circuit that you want to add that air conditioner to. Maybe your fridge or microwave is already on it and those are big current hogs. It could be the circuit is just overloaded and can't handle much more current. In our old house we had to turn off the bedroom air conditioner before my wife could dry her hair in the bathroom on the other side of the house!

But if the circuit breakers are tripping with very few things plugged in and running you may have a problem. Could be bad insulation on the wires somewhere, and that's a hazard. 

It might be a good idea to get some estimates from electricians to add a dedicated 20-amp outlet to your bedroom. Then you don't have to worry about it.

drummerboy and I were furiously typing at the same time.

Yes, the Home Depot website is a great resource for researching. And I was being cavalier with my BTUs. You should figure out what you need the right way.

I bought multiple appliances and ACs from Karl's in Orange (East Orange?) over the years. I was always impressed at their expertise and product knowledge. For example, I called once to inquire about replacing a through-the-wall AC unit. The guy sounded like an encyclopedia, spouting out information about sizes and BTUs were available that would fit in the existing chassis. They really know their stuff. And they will probably have opinions on whether it would be safe.
