To figure out how many watts your 2.5 ton air conditioner uses, you can use the SEER rating or the label, a smart electrical meter or a thermostat.
Out of all the appliances in your house, your air conditioner (AC) will probably be one of the appliances with the highest energyconsumption.
The energy that an air conditioner uses to run is measured in watts and to figure out how many watts a 2.5 ton air conditioner uses, you can rely on averages or measure the energy usage of your specific AC unit.
Do air conditioners use a lot of power?
One of the top concerns for air conditioner owners is the energy usage of these appliances. Although most modern air conditioners are designed to be much more energyefficient than their predecessors, air conditioners are still some of the appliances that use the most electricity within your home.
However, there are still ways that AC owners can be strategic when it comes to their air conditioners’ energy usage and to monitor this usage closely.
How many watts does a 2.5 ton air conditioner use?
Although the energy consumption of air conditioners is relatively high, it is always helpful to know how many watts your 2.5 ton air conditioner uses.
The energy that an air conditioner requires to operate is measured in watts. This means that to know how much power your air conditioner uses, you need to figure out how many watts your 2.5 on air conditioner uses to operate.
On average, a 2.5 ton air conditioner uses about 1200 watts to 3500 watts to run, but every model differs slightly from the next. The main factor that determines how many watts every individual 2.5 ton air conditioner model uses, is the SEER (Seasonal Energy Efficiency Ratio) rating of the unit.
One of the easiest ways to determine how many watts your 2.5 ton air conditioner uses is to look at a chart that can help you to match the SEER rating of your unit with the average wattages for similar units.
However, if you want a more specific and accurate measure of how many watts your specific air conditioner uses, you can determine this by looking at the label on the side of your unit, and using a smart electrical meter or a smart thermostat that will track your air conditioner’s power usage.
Once you have determined how many watts your 2.5 ton air conditioner uses, you can also employ some tactics to lower this energy usage over time.

How to determine how many watts your specific 2.5 ton air conditioner uses
Although getting a general idea of how many watts the average 2.5 ton air conditioner or even models with varying SEER ratings use, if you want to get specific figures of many watts your air conditioner uses, there are a few different methods to try, including:
Method 
Description 
Availability on Amazon 
Method 1: Looking at the label 
Air conditioners should have a metal plate or label printed on the side of the unit which has all of the unit’s necessary electrical information, including the kilowatt usage of the unit 

Method 2: Using a smart electrical meter 
This device is connected to your home’s circuit board and measures the electricity consumption of each circuit, including the one for your air conditioner 

Method 3: Using a smart thermostat 
The mobile applications that work with the smart thermostats can monitor the energy usage of your air conditioner in several modes and circumstances 
How to reduce the number of watts that your 2.5 ton air conditioner uses
If you have determined how many watts your 2.5 ton air conditioner uses and you want to reduce this amount as much as possible, there are a few ways that you can go about this, such as:
 Insulate the doors and windows in your space to reduce the load on your air conditioner
 Ensure that your air conditioner is clean and wellmaintained
 Change the settings throughout the day so that the air conditioner is not operating at full force the whole day
