Nobody wants to stay in a hot and humid place, right? Air conditioners are widely used to cool down the temperatures in our rooms.

That being said, air conditioners consume a lot of power. So, you might be wondering how much power a 4 ton air conditioner consumes. Let’s find the answers to all your queries about the power consumption of a 4 ton air conditioner.

**How much power does a 4 ton air conditioner use?**

**The amount of power a 4 ton air conditioner will need depends on the technology, features, and model of the unit. Generally, a 4 ton air conditioner uses 4000 watts of power per hour to work. If there are additional features added to the air conditioner then the power consumption will increase.**

The amount of power an air conditioner uses mainly means what amount of electricity it will consume while operating. It is measured in watts.

A 4 ton air conditioner uses 4000 watts of electric power in an hour. It means that the air conditioning unit will need 4000 watts of electricity to operate and cool down a room per hour.

Since the 4 ton air conditioner is usually used as central air conditioning units, it requires a high amount of power to work flawlessly.

The high power consumption rate of this unit is somewhat justified since it can be used to control the temperature of a 2,500 square feet area.

That being said, the power consumption of the 4 ton air conditioner varies from unit to unit. It mainly depends on the built, integrated technology and features, and fan speed.

If the 4 ton air conditioner has a high fan speed and additional features are added, then the unit will consume more power than the regular units.

In addition to that, the 4 ton central air conditioner can also use more power than the regular 4 ton air conditioners. Let’s find out how much power a 4 ton central air conditioner uses.

**4 ton central air conditioner:**

A 4 ton central air conditioner also uses the same amount of power as a normal 4 ton air conditioner. It uses around 4000 watts of electric power per hour to work properly.

However, **the power consumption of the 4 ton central air conditioner can go up to 5 kWh if there are additional features in the unit.**

**How many watts does it take to run a 4 ton air conditioner?**

**It takes 4000 watts per hour or 4 kilowatts per hour to run a 4 ton air conditioner.** It basically means that a 4 ton air conditioner consumes 4000 watts of electricity if it runs for an hour.

If it operates for two hours, the electric power consumption of the 4 ton air conditioner will be 8000 watts.

However, there are some 4 ton air conditioners that will draw around 4700 watts to 5000 watts of electric power per hour. It mainly depends on the performance and the features of the unit.

Otherwise, 4 kWh is needed to run a 4 ton AC unit. This air conditioner size is considered a large-sized unit as it can cool down a 2,500 square feet apartment or office space. So, the 4 ton air conditioners are also used as a central unit.

**How many amps does a 4 ton AC pull?**

**A 4 ton AC pulls from 26.4 amps to a maximum of 45 amps.** However, there are a few 4 ton air conditioners that pull only 15 amps per hour.

Amps short for amperes is the unit of electrical current. The electrical current means the movement of charged particles through an electrical conductor or space.

The electrical current is determined by the number of electrons that pass through an electrical conductor in a second.

The 4 ton air conditioners pull a huge amount of amperes as a high amount of charge particles passes from one conductor to another to start and run the unit.

**What size generator do I need to run a 4 ton AC unit?**

**To run a 4 ton air conditioner unit flawlessly and without any issue, you will need to use a 17 kilowatts generator.** This is the ideal sized generator required to run a unit as large as the 4 ton air conditioners.

That being said, you can also opt for a 12 kW or 14 kW generator to run your 4 ton AC unit. However, that won’t be a very good choice as the generator won’t be able to provide backup for the air conditioner for a long period of time.

The smaller-sized generators won’t also be able to provide enough wattage and amperes to run the air conditioning unit properly. If the air conditioner is operated using a small generator it can also harm the AC unit.

So, while choosing which generator to use for your 4 ton AC unit, you must be very careful and cautious. Ensure that the unit is compatible and strong enough to provide backup to your appliance.

**Factors that determine ac wattage usage**

There are multiple factors that determine the AC units’ wattage usage. It is very important to know which factors determine the wattage usage of air conditioners so that you can choose the right AC unit for you.

Here are the factors that determine the AC wattage usage:

**Type of the air conditioner:**

The type of the air conditioner is a very important factor that determines the wattage usage of an air conditioner. Depending on what type the air conditioner is, the power consumption massively varies.

The inverter air conditioners consume a lot less electrical power than the regular units. Then again, the ducted air conditioners use somewhat higher wattage than most other AC units available on the market.

**Insulation:**

A properly insulated house or home means that the cold air won’t be able to escape the space when the windows and doors are closed. So, in a properly insulated space, the air conditioner unit requires less electric power to run.

**Maintenance:**

A properly and regularly serviced air conditioner unit will consume a lot less wattage as the filters will be clean. It is recommended to service your air conditioner at least twice a year to ensure efficient wattage usage.

**Climate:**

The climate in your area greatly influences the wattage usage of the air conditioners. If the climate in your region is very hot and humid, the AC unit will need a lot more power and current to reduce the temperature in the room.

**How do I determine the wattage of my air conditioner?**

Determining the wattage of an air conditioner is not as complicated as it may seem to you at first. It is quite simple and you can do it with a little bit of effort and time.

Let’s find out how you can determine the wattage of your air conditioner.

**Calculate the electrical current and potential difference:**

Ampere is the unit for electrical current and the voltage is the unit for electrical potential difference. By calculating the amperage and voltage of an air conditioner, you can determine the number of watts it needs to run properly.

Note down the ampere and voltage of your air conditioner from the specification sheet. After doing that, just multiply the amperage with voltage and you will find the wattage of the unit.

For example, if the voltage of an air conditioner unit is 220 volt and the amperage is 20 amps, then the wattage will be 4400 watts.

**Check the BTU and EER rating:**

To determine the wattage of your air conditioner you can use the BTU and EER rating of your air conditioner. The BTU is the British Thermal Unit and EER is the Energy Efficiency Ration.

By dividing BTU by EER, you can easily find the wattage of the unit. So, if you are using an AC unit of 48,000 BTUs and an EER of 10, then the wattage of the unit will be 4,800 watts.

**Final Thoughts**

The power consumption of a 4 ton air conditioner is 4000 watts per hour on average. There are a few units that even use electrical power from 4500 watts to 5000 watts per hour. It varies from unit to unit depending on the make and the included features.
