How Much Electricity Does A 2.5 Ton AC Use?

The central AC table below shows how much power 15 ton air conditioners use every hour, month, and year.

According to the graph, a 2.5 ton central air conditioner consumes 1.88 kWh of electricity every hour. This means that a 2.5 ton central air conditioner needs 1350 kWh per month and 2475 kWh per year.

A 2.5 ton central air conditioner consumes how many watts?

I can assist you.

I just finished installing a similar item that uses the same compressor.

A 2.5 ton air conditioner will need roughly 7.5 amps.

When you double this by 240 volts, you get 1800 watts.

The second thing to consider is the blower in your furnace, which is working at the same time as the AC condenser outside.

If you have a typical furnace with a PSC motor, it will draw approximately 5 amps.

You multiply this by the voltage (120 in the case of a furnace) to get 600 watts.

As a result, when you combine the two together, the total wattage for each hour of run time is 2400.

How much electricity does a 2 ton air conditioner consume?

Air conditioning is almost always fueled by energy, which is rarely free. Knowing this, you might be curious as to how many watts a 2-ton air conditioner consumes. Here, we provide a comprehensive response to your query based on the most recent research and industry expert knowledge.

The wattage needed of a 2-ton air conditioning unit varies depending on the model and manufacturer. The cooling capacity of the AC unit is measured in tons, whereas the immediate energy requirements are measured in watts. A 2-ton air conditioner uses between 500 and 7,033 watts, depending on the SEER rating.

Continue reading this post for a more in-depth examination of AC unit watt needs. This provides a detailed explanation of what the SEER rating means as well as a formula for calculating watts based on tonnage and SEER. Finally, we respond to a number of relevant questions.

How much energy does a 3.5 ton air conditioner consume?

As a general guideline, a three ton central air conditioner consumes 3500 watts per hour, whereas a 12,000 watt window unit consumes 1200 watts per hour.

How much electricity does an air conditioner use in a month?

An air conditioner costs between $0.06 and $0.88 per hour to run on average. Let’s see how much air conditioning costs every month (assuming it runs for 8 hours per day): The cheapest option is $14.40 per month. $211.20 per month on the high end.

Is it true that central air consumes a lot of electricity?

The central air conditioner unit is usually positioned outside of the house and connected to the duct system, which distributes clean, cool air throughout the house. Furthermore, estimates of electricity use will vary depending on the model, room/outdoor temperature, time of use, and energy pricing in your area.

In states like Arizona, for example, most air conditioners operate for nine hours or more each day for several months of the year. In some states, such as Minnesota, air conditioning is only used for three months or less of the year. The climate in which your home is situated will have the greatest impact on the wattages used.

The electrical consumption of a central air conditioning machine varies between 3,000 and 5,000 watts per hour of use. The typical central air conditioning unit consumes 3,300 to 3,500 Wh and weighs between 2,000 and 2,500 pounds.

These watts per hour are calculated with the air conditioner set on chill. Assume you were solely using the fan setting to circulate the air. The output would be reduced to around 750 watts every electrical hour.

How can I figure out how much AC power I use?

You’ll need the following three items to manually calculate your AC power consumption.

  • The wattage of your air conditioner The unit of power is the watt. It refers to the rate at which a gadget consumes or produces electricity. A 50 watt electric fan, for example, consumes 50 watts every hour. This does not imply that the fan utilized 50 units of electricity, but rather that it will consume 50 watts every hour.
  • Hours of operation
  • The number of hours your appliance, in this case an air conditioner, has been running.
  • The amount your electricity provider costs you for one unit (kWh) of power is known as the electricity tariff. The electricity rate in Mumbai, India is Rs 12 per kWh. Simply enter the electricity tariff in your location into the calculator.
  • kWh stands for kilowatt hour.
  • The energy consumption of a device is measured in kilowatt hours (kWh) or units. A 50 watt electric fan, for example, will use 50 watts x 50 hours = 2500 watt hours = 2.5 kilowatt hours of electricity = 2.5 units of electricity.

As a general rule of thumb, while calculating AC power consumption, you should factor in

  • 1,000 watts Equals 1 ton of cooling
  • 1,500 watts Equals 1.5 ton of cooling
  • 2,00 watts Equals 2 ton of cooling
  • 3 ton cooling equals 3000 watts, and so forth.

What To Do With The Calculated Result:

Whatever figure you obtain, double it because your AC compressor is only active 50% of the time, whether you have a conventional or inverter air conditioner.

Is it more cost-effective to use a window air conditioner instead of central air?

It all boils down to two primary variables when deciding between a window unit and a central air conditioner: cost and efficiency.


There’s more to it than the purchase price of an air conditioner. Other expenses include monthly electricity bills and operating expenses. When deciding on the ideal unit for your home, choose one that will be less expensive in the long term.

Purchasing and maintaining a central air conditioner will be more expensive than purchasing and maintaining several window units (more than 5).


This is a measure of how successfully an air conditioner does its job. This covers factors such as the size of the air conditioner and its ability to maintain comfortable room temperatures.

In addition, your air conditioner must operate at optimal efficiency while spending minimal electricity.

If you live in a hot environment, this is especially crucial; air conditioners in Phoenix, for example, run for most of the year and can rack up big expenditures if inefficient.

How much electricity does an air conditioner consume per hour?

The amount of electricity that 3-star and 5-star air conditioners consume once installed is one of the primary variations between the two versions. The EER rating of an air conditioner determines how much power it uses. A 5-star air conditioner uses less energy than a 3-star air conditioner. A 5-star AC (1.5 tons) consumes about 1.5 units of power per hour, whereas a 3-star AC (1.5 tons) consumes 1.6 units per hour.

Is it cheaper to use fans or air conditioning?

Fans are less expensive to run than air conditioners and can be used instead of or in addition to them to save money. If you have a ceiling fan, turn it on at the same time you turn on the air conditioner. Cooler air is pushed down and over the bodies of everyone in the room.
