Power Consumption of a 1.5 Ton AC: What You Need to Know

power consumption of a 1.5 ton ac
Summarize and analyze this article with:

Are you curious about how much power a 1.5 Ton AC uses? It’s surprising to learn that there are various factors that determine the answer. Nowadays, we rely heavily on air conditioners to stay comfortable as they have become essential tools for cooling our homes and businesses.

Through this blog, we will discuss the power usage of a 1.5 Ton AC and the different factors that impact it.

What will be the power consumption for a 1.5 Ton AC?

Over a long run, a higher star rating means higher efficiency hence lower electricity costs to run the AC.

An air conditioner 1.5 Ton’s power consumption is based on its energy rating. Greater energy efficiency, shown by a higher star rating, means that your air conditioner will use less energy to cool your space.

When compared to a 3-star AC, a 5-star AC may save up to 28% on electricity. Even while a one-star air conditioner could cost less up front, over time its higher operating costs might offset the savings.

Consequently, for a long run, selecting an air conditioner with a higher star rating might end up being more economical.

What is the power consumption of 1.5 ton AC per hour?

To accurately calculate the running cost of a 1.5 ton air conditioner per hour, you only need to consider two factors: power and wattage. 

The wattage is crucial in determining the electricity consumption of a 1.5-ton AC unit. There are two ways to calculate the wattage: you can either check the label on your air conditioner or refer to the EER rating.

For instance, portable AC units with a three-star rating or 1.5-ton windows with an EER value of nine or lower typically have a power of 2,000W when operating at full cooling capacity.

On the other hand, a more energy-efficient 5-star 1.5-ton air conditioner usually has around 11 of an EER rating, requiring approximately 1,600 watts when running at maximum power.

The price of electricity per kilowatt-hour is what determines the cost of using electricity. If you know the wattage of your 1.5-ton air conditioner, you can easily calculate how much power it consumes in kilowatt-hours.

To find out the hourly cost of running your air conditioner, simply multiply the unit price by the kilowatt-hours used.

What is the power consumption of 1.5 ton AC per month?

To calculate the monthly power consumption of an air conditioner, you can use the following calculation: Multiply the kilowatt hours used by the air conditioner per hour by hours of operation daily and do it for all the days of the month to get to the total number of days of consumption in a month.

Let us say, we have a branded 1.5 kW AC. It runs for 10 hours a day in a month of 30 days, with an initial consumption of 1.5 kWh per hour. 

Monthly energy consumption will be calculated as follows: 1.5 kWh per hour x 10 hours per day x 30 days = 450 kWh.

For instance, the electricity cost  per unit is ₹ 7. To calculate the amount of electricity consumed by the AC on a monthly basis, we can use the formula: 

Monthly electricity price of the air conditioner = units per month x unit cost. 

If we plug our price forecast into the calculation, we find that the monthly electricity price for the AC will be ₹ 3150 (450 units x ₹ 7).

What are the factors that affect AC power consumption?

The energy consumption of your air conditioner is influenced by various factors, depending on its energy rating and tonnage:

  • In a room, the number of individuals present can affect the amount of air conditioner’s power required to keep it cool. For instance, a larger group of twenty to twenty-five people may need multiple air conditioners, whereas a smaller group of three to five people may only need one unit.
  • The size and capacity of the air conditioner also impact its energy usage. An oversized AC unit may cycle on and off frequently, leading to inefficient cooling and higher energy consumption.
  • A room’s size has a significant impact on how much electricity the AC uses. The amount of power consumption of an AC increases with the room size, while the smaller rooms cool down with less power consumption.
  • Proper maintenance and regular cleaning of air conditioning units can improve their energy efficiency. Dirty filters, clogged coils, and blocked vents can restrict airflow and make the AC work harder, consuming more electricity.
  • The location and orientation of the air conditioner can affect its energy usage. Placing the AC unit in direct sunlight or near heat sources can cause it to work harder and consume more power.
  • Energy-saving features such as sleep mode, timer functions, and smart controls can further optimize energy usage by adjusting cooling levels based on specific needs and preferences.
  • Central air conditioners are typically more energy-efficient than window or split AC units, as they can cool multiple rooms or an entire house with a single system.
  • The temperature settings and usage patterns of the air conditioner can impact energy consumption. Setting the thermostat at a higher temperature or using programmable settings to adjust cooling based on occupancy can help save energy.
  • The insulation and sealing of the room or building also play a role in energy consumption. Well-insulated spaces can retain cool air more effectively, reducing the workload on the air conditioner and lowering electricity usage.
  • The overall energy efficiency of the building or home, including factors such as insulation, ventilation, and shading, can influence the energy consumption of the air conditioner. A well-designed and energy-efficient building can reduce the cooling load and decrease the power required by the AC unit.

How to reduce the Power Consumption of 1.5 ton AC?

High power consumption comes with a huge monthly electricity bill. Knowing the way to reduce your air conditioner’s power consumption can be a solution to beat the heat with less budget than usual. Here are a few pointers to save on your power consumption while using a 1.5 ton AC:

  • Make sure to keep your room’s window and door closed for improved cooling and less consumption.
  • Switch off the AC when not in use.
  • Protect your AC’s compressor from direct sunlight.
  • Filters must be cleaned regularly.
  • For cooling the room faster than usual, you can put on the ceiling fan.
  • Exchange or sell your old AC when it is consuming more power and buy a new one.
  • Keep its servicing up to date.
  • Maintaining the AC at its optimal temperature may consume less power.

Conclusion 

The scorching Indian summer is notorious for bringing higher temperatures and increased discomfort. The best solution to beat the heat and avoid sweating is by using an air conditioner.

However, it comes with a significant monthly power cost. While we can’t provide an exact estimate of your air conditioner’s power consumption, we hope this article has given you a better understanding of what to expect.

It’s important to know the operating cost of your unit as it helps you determine when to use it and when to explore alternative cooling methods instead of relying solely on air conditioning. 

Additionally, we’ve included some helpful tips on reducing your energy usage.For those looking to save on costs, consider exploring the best deals on second-hand ACs at OLX India, the biggest second-hand marketplace.

FREQUENTLY ASKED QUESTIONS ( FAQs):

  • Is the performance of an AC affected by its ratings?

Yes, AC’s power consumption is based on its energy rating. Greater energy efficiency, shown by a higher star rating, means that your air conditioner will use less energy to cool down your space. So it is always better to choose for an AC with higher ratings.

  • Can a 1.5 ton AC be used in a smaller space?

Definitely yes. 1.5 ton AC cools your small cozy rooms quickly and for a long time. For small spaces, this AC can be the perfect choice.

  • Does 1.5 ton AC have a noise concern?

While a split AC can be really silent, a window AC might be good to avoid if you can’t bear compressor noise at all.

  • When AC gets old, should I keep servicing it or sell it?

We will recommend you to buy a new AC with improved features as the older one might require a lot of maintenance adding unnecessarily extra budget to your pocket along with higher energy consumption.
