What Does BTU Stand For?
BTU is an acronym that stands for British Thermal Unit. It’s an international standard for a form of measurement that measures energy. One BTU refers to the amount of energy that’s needed to increase the temperature of a pound of water by 1° F.
BTU measurements are used when talking about heating and air conditioning units.
What Do BTUs Mean for Your Portable AC?
All portable air conditioners come with a BTU rating that tells you how powerful the unit is.
Although air conditioners remove heat from the air and circulate cool air back in, the BTU measurement still applies. Instead of measuring the amount of heat added to the air, a portable AC BTU rating measures how much heat is removed.
Similar to heaters, the higher the BTU rating of a portable air conditioner, the more powerful it is at cooling a room. Higher BTU ratings equal more square footage for the portable AC unit to cover.
How a Portable Air Conditioner Can Save You Money
Customize the Coolness
Portable units can reduce the cost of indoor temperature control by allowing you to target one room at a time, and when running on a schedule, can even take the place of your existing central air system by keeping only high-traffic areas cool.
Enjoy Year-Round Temperature Management
Having a central air conditioning system is no reason to forego the money-saving benefits of using a portable unit.
Such an investment can help keep your energy costs manageable all year long, especially when the unit is used with a central system that stays running at a higher temperature.
Some portable units even have heating capabilities, adding to their year-round value.
Some portable air conditioners look and function more like high-tech gadgets than simple air conditioning units.
Rule of thumb: the more features the machine has, the more likely it is to save you some serious cash.
Some of the nicest machines on the market come equipped with apps and other features that allow homeowners to control temperatures all day long, whether they are at home or away.
Keep temperatures up when nobody is home, but adjust the temperature to something more comfortable before you get back (without running the central AC system for no reason).
There are lots of portable air conditioners out there that double (or even triple) as several machines in one.
For example, some units are air dehumidifiers and/or HEPA filter air purifiers as well as powerful air conditioners.
If the unit includes a dehumidifying function then it can lower the humidity levels inside your home which also makes it feel cooler.
If it has a HEPA filter, it can act as an air purifier to remove airborne pollutants like dust, allergens, smoke particles, bacteria, and more.
Just remember, the BTU is still a good indication of how much space will be affected by a multi-tasking portable unit.
The higher the BTU of the machine, the more space the unit will cool.
Make Your Home More Efficient
Central air conditioning units are notorious for using a lot of energy. Portable units are known to run much more efficiently, not to mention they are super easy to install and maintain.
While central AC has its benefits, installation can be extremely expensive and upkeep is always a chore.
Customization is out of the question, so to cool one specific area of the home it requires the entire system has to be powered on.
If you want to save the most money on your electric bill and only have a small room to cool, consider getting a small room air conditioner. Using this unit to supplement your cooling during the hot months can save you a considerable amount of money.

As you learned, a portable air conditioner can save you a substantial amount of money when compared to a central air conditioning system.
The exact answer for how much does it cost to run a portable air conditioner depends on the BTU rating of the unit.
