15 SEER 4-Ton AC | 3200 Watts | 5517 Watts |

16 SEER 4-Ton AC | 3000 Watts | 5172 Watts |

17 SEER 4-Ton AC | 2824 Watts | 4868 Watts |

18 SEER 4-Ton AC | 2667 Watts | 4598 Watts |

19 SEER 4-Ton AC | 2526 Watts | 4356 Watts |

20 SEER 4-Ton AC | 2400 Watts | 4138 Watts |

21 SEER 4-Ton AC | 2256 Watts | 3941 Watts |

22 SEER 4-Ton AC | 2182 Watts | 3762 Watts |

23 SEER 4-Ton AC | 2087 Watts | 3598 Watts |

24 SEER 4-Ton AC | 2000 Watts | 3448 Watts |

25 SEER 4-Ton AC | 1920 Watts | 3310 Watts |

## How To Calculate Air Conditioner Wattage?

To calculate the wattage of a 4 ton AC unit, you can follow the steps below:

### the cooling capacity of the AC unit

Determine the cooling capacity of the AC unit in BTUs (British Thermal Units). A 4 ton AC unit has a cooling capacity of 48,000 BTUs.

### Convert the BTUs to watts

Multiply the cooling capacity (48,000) by 0.2931. This gives you 14,044.8 watts.

### Factor in the SEER (Seasonal Energy Efficiency Ratio)

The SEER rating is a measure of the AC unit’s efficiency. The higher the SEER rating, the more efficient the unit is.

For example, if the SEER rating is 16, you would divide the wattage (14,044.8) by 16 to get 877.8 watts.

### Account for the power supply voltage.

Most AC units in the US run on 120 volts, while some larger units may require 240 volts.

If your 4 ton AC unit requires 240 volts, you would need to divide the wattage by 240 instead of 120 to get the amperage.

## Which Factors Affecting On AC Power Consumption?

Multiple factors will affect the power consumption of your air conditioner. These include:

### The size of your air conditioner

An air conditioner that is too small or too large for the room will have to work harder, using more power, to maintain the desired temperature.

### Age of air conditioner

Older air conditioners are less efficient than newer models and will use more power.

### Cooling capacity

A higher cooling capacity means that more power is required to operate the unit.

### SEER rating

The Seasonal Energy Efficiency Ratio (SEER) is a measure of how much cooling your air conditioner can provide per watt of power consumed.

You need to know that, if the SEER rating is higher, then more efficient of the Ac.

### No of people in the room

More people in the room will generate more heat, requiring the air conditioner to work harder and use more power.

### The room temperature

A higher temperature will require the air conditioner to work harder to cool the room down, using more power.

### The insulation of Ac

Good insulation will keep the heat out, making it easier for the air conditioner to cool the room and use less power.

### Number of windows

More windows mean more heat coming into the room, making it harder for the air conditioner to maintain the desired temperature and use more power.

### The sun exposure in the room

A room exposed to direct sunlight will be warmer, making it harder for the air conditioner to maintain the desired temperature and use more power.

### The number of appliances in the room

Appliances generate heat, making it harder for the air conditioner to maintain the desired temperature and use more power.

## FAQs on How Many Watts A 4 Ton AC Unit Use

### How Much Power Does 4 Ton Of AC Consume?

The consumption of a four-ton air conditioner is around 4 kWh per hour.

If a four-ton air conditioner consumed 12 kWh each day, the usage would be 48 per day.

Keep in mind that the size of the air conditioner is not the only factor that will affect power consumption.

### How Many Units Does AC Consume Per Hour?

It depends on the size of the AC, the age of the AC, cooling capacity, the SEER rating, and other factors.

But A 5-star air conditioner (1.5 tons) consumes 1.6 units each hour.

Whereas a 3-star air conditioner (1.5 tons) uses 1.7 units each hour.

So, a 5-star 1.5 ton AC would use 40% less power than a 3-star 1.5 ton AC.

### Is It Cheaper To Run AC All Day?

Your air conditioning will last considerably longer if it is left on all day instead of being turned off.

It is cheaper to run the AC all day if you have good insulation in your house.

If you do not have good insulation, turning the AC off when you leave the house is better.

So, it all depends on the insulation of your house.

### Why Does AC Use So Much Electricity?

Inside the evaporator coil, the Freon is pressurized and turns from a liquid to a gas.

As it evaporates, it absorbs heat from the air around it, cooling the air inside your home.

When the Freon reaches the compressor, it is turned back into a liquid so that it can start the process again.

This process uses a lot of electricity.

## Final Thoughts

We hope this article has helped you understand **how much power an air conditioner uses **and the factors that affect its power consumption.

Be sure to consider all of these factors when searching for an air conditioner.

So that you can find the most efficient model for your needs. Also, be sure to check the SEER rating to ensure that you are getting a quality air conditioner.
