What Makes These A/C Units Energy Efficient?
These A/C units are energy efficient because they require less power to operate. Advances in A/C technology have enabled today’s window units to consume far less juice, yet still produce large amounts of cool air. Some units also “recycle” their cooling water, making it last a lot longer.
Other units use additional energy saving techniques, such as side panels that seal in the cooler inside air while also blocking the hotter air from outside. You will be impressed at how little your electrical bill increases when using one of these units.
How to Choose an Energy Efficient Window Air Conditioner
There are a number of qualities you will want to consider when buying a window air conditioner:
This is clearly the main reason you are looking into window units – to cool off without being slapped with a giant power bill or the high cost of implementing a central air conditioning system. Keep an eye out for a unit’s EER rating – that stands for Energy Efficient Ratio, which will be a good comparison point on this factor.
What good is an air conditioner if it does not cool you off? Get yourself a window unit that will consistently and effectively deliver cool air on a reliable basis, so you can turn it on and forget about it – and forget about being hot – completely.
Ease of Operation
You need a window unit that is going to work well for you, not something you are going to have to constantly fiddle with to get it to the exact right temperature you are seeking. Set it and forget it with an air conditioner that has simple dials or setting systems.

It also has extra side panels to seal in cooled indoor air.

Window air conditioners can be one of the worst things in the world to repair – not only does it often take a specialized skill set to fix them, but by nature of the air conditioner not working, you are going to be drenched in sweat and cranky the whole time you are fiddling with your tools. Skip the stress and invest in a unit that will last a long time.

Stuff like automatic timers, so the unit will kick on right before you go to work or kick off right after you fall asleep and remote control operation can really improve your air conditioning experience.
Energy efficient air conditioners are the way of the future – they will cut down on your energy costs while still effectively cooling your entire living space. Make sure you find yourself an air conditioner that will fit your specific window and room sizing needs and you will never have to worry about being hot again.
