Air conditioners draw huge quantities of energy to maintain your private home cool and comfy. Sadly, this could imply the next electrical energy invoice in addition to added stress on your private home’s backup battery storage throughout an influence outage.
You will have to know what number of watts your air con unit makes use of in an effort to allocate the facility required to run it in your backup battery storage. Let’s break down what number of watts a typical air conditioner makes use of, why these watts matter, and how one can save in your electrical invoice.
Key takeaways
- The quantity of watts an AC unit makes use of will depend on the kind of system and its measurement, however you may assume it makes use of round 1,000 watts.
- Along with the wattage, search for the SEER and BTU score to greatest perceive an AC’s mandatory energy consumption.
- Photo voltaic panels will help maintain your electrical payments down, however the unit will nonetheless use giant quantities of electrical energy to run, regardless of your energy supply.
What number of watts does a typical air conditioner use?
An air conditioner makes use of a mean of about 1,000 watts. This quantity relies upon, although, on a number of elements corresponding to the kind of air conditioner, the scale, and the way arduous it must work in an effort to quiet down the designated area.
BTUs defined
Every AC unit makes use of a selected measurement to find out its cooling capability referred to as BTUs or British Thermal Units. BTUs measure your air conditioner’s means to take away warmth from your private home’s air over a selected interval, normally an hour. Whereas a window air conditioner is perhaps rated at round 5,000 to 10,000 BTUs, a residential central air con unit might common between 20,000 to 50,000 BTUs.
Because the BTU score is basically a measurement of an AC’s cooling capability, that capability may also offer you an thought of what number of watts it would take to chill your area.
| BTU AC | Watts |
| 5,000 | 41 -625 |
| 10,000 | 833-1,500 |
| 15,000 | 1,250-2,250 |
The main points of your particular air conditioner may be discovered on the machine’s label, however in case you are blasting your AC, it can use extra energy.
SEER rankings defined
An air conditioner’s SEER or Seasonal Power Effectivity Ratio score is a measurement of how environment friendly an AC unit is. These measurements vary all around the map, however a 13 SEER score is a stable jumping-off level.
Components that affect air conditioner electrical energy utilization
Even when you’ve got essentially the most environment friendly AC that’s Energy Star-rated, there are exterior elements that may make it work more durable. Parts corresponding to temperature, humidity, residence insulation, and whether or not the AC unit has been working all day sometimes impacts its power utilization.
Remember to purchase an air con unit that’s giant sufficient to chill your private home. If the system you buy is simply too small, it might want to work further arduous to chill down the area.
Overworking your AC unit will drive up the watt utilization, however beneath typical circumstances, your AC will use the quantity of watts that seem on the label.
What number of watts do the various kinds of air conditioners use?
A window unit is way smaller than a central air conditioner, and as such, wants completely different quantities of watts to run. To offer you an thought, we’ve rounded up the common watts utilized by the most typical forms of air conditioners: transportable air conditioners, window items, and central AC techniques.
Transportable air conidionters
Transportable air conditioners present a variety of energy in a small compact measurement, however in addition they use a variety of power. Picture supply: Whirlpool
Transportable air conditioners supply comfort, much less noise than window items, and unbelievable cooling means. You may anticipate these items to make use of between 700 and 1,500 watts. Whereas transportable air conditioners is perhaps a house owner’s solely choice, remember that they use a variety of electrical energy to function.
Window unit air conditioners
Window air conditioners can quiet down surprisingly giant rooms for his or her measurement. Picture supply: People
Window items are an important complement if a full HVAC system isn’t an choice. You may anticipate them to make use of about 500 to 1,000 watts an hour relying on the scale of the unit and the sq. ft of the area the unit wants to chill down.
Central air conditioners
Central AC items are fairly intricate, however do an important job at retaining your private home cool. Picture supply: The Spruce
Central air con techniques are giant machines which can be normally put in exterior the house and power air out and in of ducts all through a constructing. They’re fairly environment friendly however they do cowl a good quantity of area, so you may anticipate them to make use of between 3,000 and 5,000 watts of energy.
What number of photo voltaic panels do it is advisable to run an AC?
There is no such thing as a straightforward reply to what number of photo voltaic panels it is advisable to run your AC unit. It sometimes will depend on the wattage of the unit you’re utilizing, how usually your AC unit is on, and the way a lot energy your photo voltaic panels are producing on the time you are utilizing your AC.
In case you are in search of a stable reply, primarily based on the common watts of all AC items, you may assume that you simply want at the very least three 350 W photo voltaic panels for the common AC wattage of 1,000 watts (at the very least in our hypothetical instance). A 350 W panel will produce about 350 W per hour, so three panels can present 1,050 W to energy your AC unit. Air con items are typically electrical energy guzzlers regardless of the way you get your energy.
You probably have air con in your own home previous to getting photo voltaic put in, your photo voltaic installer will take your power consumption into consideration when constructing out a photo voltaic system. In case you are putting in AC after your photo voltaic panels, or need to perceive how a lot electrical energy it is advisable to retailer in a storage battery to run AC throughout an influence outage, realizing the watts your system makes use of is essential.
As an example, a backup battery can not present sufficient energy for each equipment in your house if the electrical energy goes out. When you outline your AC as a vital load – one thing that should run if the facility is out – calculate that into your determination.

How can solar panels cut your electric bill?
As a general rule, no matter how many watts your AC uses, solar panels can help you cut your energy bills. When solar systems are installed, an installer determines the average electricity usage of your home and builds out the system size that can power that average electricity usage.
Solar can help you save money in a few ways by providing most or all of your electricity and reducing your bill or by net metering benefits that can pay you for the excess electricity that your panels produce.
If you do not have solar, monitoring your AC use can help you cut back on bills. Supplementing your home cooling system by adding ceiling fans, keeping window shades down during the day, and pre-setting your thermostat can go a long way in keeping your house cool.
The general rule is that the bigger the air conditioner or the more space it needs to cool down, the more watts it will take to do it. Buying a more energy-efficient air conditioner unit model can keep the watts low and the cool air flowing.
