It is more expensive, but it uses far less energy. An traditional 1.5 tonne air conditioner consumes about 1.5 units per hour, whereas an inverter air conditioner consumes only 0.91 units per hour.
What is the typical monthly electricity bill in Pakistan?
In Pakistan, the National Electric Power Regulatory Authority (NEPRA) recently increased electricity costs across the board, including residential electricity tariffs for users using more than 300 kWh per month.
I detailed how our electricity bill is computed using the slab tariff system shown above a few years ago. Check it out if you want to learn more about the billing system before reading on to find out what’s new in NEPRA’s latest release.
Residential electricity tariffs for customers who use 301-700 kWh of electricity per month have increased from Rs. 16.00 to Rs. 17.60, plus taxes, as shown. The new cost has raised by 15% for customers who consumed more above 700 kWh in a month, from Rs. 18.00 to Rs. 20.70. Remember that you receive the advantage of the slab underneath as well. For example, if your bill exceeds 700 units, the first 700 kWh will be charged at Rs. 17.60, and all subsequent units would be charged at Rs. 20.70. Of course, there’s also tax to consider.
However, things are no longer so straightforward. For many home consumers, this is good news. Even if they use more than 700 units per month, many customers will see a reduction in their expenses.
This is because NEPRA has mandated Time of Use (TOU) charging for all customers with a sanctioned load of 5kW or more. NEPRA implemented TOU billing and made it mandatory a few years ago. It has not, however, been enforced in cities such as Karachi. Until now, that is.
Clause XXXII of NEPRA’s recent ruling requires K-Electric to begin offering TOU invoicing for all customers with a sanctioned load of 5kW or more immediately. From April to October, peak hours are 6:30 p.m. to 10:30 p.m., and from November to March, 6 p.m. to 10 p.m. The remaining 20 hours of the day are referred to as “off-peak.”
That means that in the summer, all customers with a sanctioned load of 5kW or more will pay Rs. 20.70 per kWh just from 6:30pm to 10:30pm (peak period), or for only 4 hours. They will pay only Rs. 14.38 per unit for the remaining 20 hours of the day, regardless of how many units of power they use in a month. + applicable taxes (always).
So, if a customer uses more than 700 units per month and has a sanctioned load of more than 5kW, their average power bill will be between Rs. 15.00 and Rs. 17.00 per unit (plus tax), depending on how many units they use during peak hours. Many clients may discover that their total amount is lower than before the price hike. That can be credited to TOU billing.
If you use more than 700 units per month on average and your sanctioned load is less than 5kW, it may be a good idea to get your sanctioned load raised to over 5kW so that you can take advantage of TOU billing and earn a lower average cost.
Nothing has changed for customers with a sanctioned load of less than 5kW and a consumption of less than 300kWh. Your rates remain unchanged, and you continue to be subsidized by all other consumers as well as the government.
Things are about to grow incredibly expensive for consumers like me who use less than 300kWh per month in the summer and have a sanctioned load above 5kW (because we have ACs installed but don’t use them). In the summer, my average rate is around Rs. 10 per kWh, and in the winter, when our consumption is less than 200 units per month, it’s around Rs. 7 per kWh. Because of TOU billing, which is imposed on all consumers with sanctioned loads exceeding 5kW, my cost would now increase to Rs. 15-17 per kWh.
By upgrading to LED lighting and replacing my old fridge with a new inverter refrigerator, I was able to reduce my use to these levels. I even had the water pump serviced to lower its power use, and I’m actively working on water conservation around the house to reduce the water pump’s demand.
Hmm, I’m starting to wonder if I should try to get our home’s sanctioned load cut to less than 5kW. I’d be able to keep my electricity cost significantly lower, but it might limit the amount of solar PV I can build on my roof and sell to the grid in the future.
However, if I do the math, I might discover that selling solar to the grid during off-peak hours and paying KE during peak hours is really more expensive than simply lowering my sanctioned load to below 5kW.
What is the price of a 1.5 ton air conditioner bill?
In the summer, a household requires an air conditioner to maintain a comfortable environment at home and at work. During the summer, customers have two options: fix or replace their existing air conditioning system. We will explain how to install an air conditioner and how to save money on your electricity bill in this article.
The air conditioner provides a cooler and more comfortable environment for the residents. During the summer, the weather can be extremely hot. As a result, having a well installed and maintained air conditioner means that you have a more pleasant day.
Let’s have a look at the many forms of air conditioning offered to users. Choosing the right type of air conditioner can assist you in making a sensible investment decision.
The demand for air conditioners has increased dramatically in the previous 5-6 years. The growth can be predicted using the graph below.
Because March is the first month of the summer season, the demand for air conditioners jumps by 80% when compared to the winter season. In India, people have been using air conditioners since mid-March. In the south Indian regions, people use 12 months.
AC Buying Tips
We’ll look at two different types of ac customers here. First, those who already own air conditioners, and second, those who intend to purchase an air conditioner this summer. To begin, learn the fundamentals of air conditioning.
#1. Types of AC
When you go to the store to buy an air conditioner, you must first pick which sort of air conditioner you want to buy, such as:
a. Window air conditioner: A window air conditioner, often known as a room air conditioner, is the most basic type of air conditioning system. They are fixed to the inside of windows or the outside of walls.
It consists of a single unit with all components contained within a single casing. As a result, the following are some of its common characteristics:
- Installation is simple and painless.
- Installation costs are lower.
- Cooling of large areas
b. Split air conditioner: A split air conditioner has two parts: an outdoor unit and an indoor unit. Its external unit is mounted on or near the outside wall of the room to be cooled.
The compressor, condenser coil, and expansion coil or capillary tube are all part of it.
The following are some of the most frequent Split AC features:
- Installation at a permanent location
- Installation is costly, but it saves money on electricity bills.
- Because the fan and compressor are outside the window, there is less noise pollution.
- Long-lasting and durable
c. Central Air Conditioner: A central air conditioner is another form of air conditioner. This air conditioner is commonly seen in hotels, conference halls, reception areas, and gyms. The central air conditioner is installed on the ceiling wall.
#2. AC Technology
The appropriate indoor temperature is maintained by a residential air conditioner in each of the house’s rooms. Air conditioners are further classified into two types based on the number of hours they are used.
Normal air conditioning is appropriate for families or individuals who just require 3-4 hours of cooling each day. It usually comes at a low price and requires little maintenance. Although they consume a substantial quantity of energy, they are inefficient in comparison to other technologies.
It has the following basic characteristics:
- Perfect for 3-4 hours of use every day
- Maintenance costs are lower.
For homes or businesses that want air conditioning for 14-15 hours each day, inverter AC is the ideal option. At all times, they maintain a stable and comfortable temperature.
It has superior energy efficiency ratings and is environmentally friendly. Not only can inverter air conditioners save money on electricity bills, but they also save money on repairs.
The following are some of its important features:
- Domestic and commercial performance at its best
- Operation that is efficient
- Higher energy efficiency ratings
#3. Rating of AC
AC has a significant environmental impact. It also uses a lot of energy, which results in hefty electricity costs. Thanks to cutting-edge technology, a wide range of air conditioners can now be classified into three categories:
- 3 star AC: Uses less energy and saves money on your electricity bill.
- 4 star air conditioning: Lowering the electricity bill is more effective.
- 5 star air conditioners are the most energy efficient, consuming the least amount of energy and saving you money on your electricity bill.
#4. Electricity Bill of 1.5 Ton AC
The typical monthly electricity bill for a 1.5 Ton AC (Window / Split or Normal / Inverter) is between Rs. 2,000 and 3,000. In the summer, if you have one 1.5 ton inverter ac with a 4 star rating, your monthly electricity bill will be around 3500 to 5000 dollars. If you have a four-bedroom house and two 1.5-ton air conditioners, your monthly electricity bill will range from Rs. 10,000 to 15,000 in April, May, June, and July.
Is it true that having an air conditioner raises your electricity bill?
“Every degree higher in the AC temperature saves roughly 3-5 percent electricity,” Majumdar remarked. Increasing the temperature of your air conditioner from 18 to 27 degrees can save you $6,240 each year.
How much energy does air conditioning use 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.
How much electricity does air conditioning consume?
In most homes, air conditioners are a must-have piece of equipment. In the summer, they pump cold air around the house to keep it at a reasonable temperature. When many people consider installing an air conditioner, they are concerned about the unit’s energy consumption. It will be easier to arrange your budget if you have an understanding of how much electricity an AC uses under regular settings. Here’s a step-by-step instruction to help you out.
1. What Is the Power Consumption of an Air Conditioner?
The amount of energy consumed fluctuates depending on a number of things. During hotter days, a central air conditioner can use up to 3,000 watts per hour on average. When you run your air conditioner in fan-only mode for an hour, it uses about 750 watts. Large portable air conditioners can require up to 4,100 watts per hour, whereas mid-sized air conditioners use roughly 2,900 watts. A large window air conditioner can take up to 1,440 watts, a medium one 900 watts, and a small one 500 watts.
2. How to Calculate the Power Consumption of an Air Conditioner
Using the information on the label, you may compute the energy consumption level of an air conditioner. The annual power consumption rate of the system can be found on the energy-saving sticker. The majority of the time, this data is reported in kilowatts. Keep in mind that 1,000 watts equals 1 kilowatt. If a unit consumes 60 watts per hour and runs for 60 hours, the energy consumption rate is 60 watts x 60 hours, or 3,600 watts per hour, or 3.6 kWh, or kilowatt-hours of electricity. You’ll also need to figure out when your air conditioner is on. Most air conditioners run for about 1,600 hours per year, or 4.4 hours per day and 132 hours per month. This value, however, will differ from one home to the next.
Make sure you understand your power tariff, or how much your provider charges per kWh of electricity. You would multiply the figures to determine the energy consumption if you have a 3,500-watt unit that you run for roughly 4.4 hours every day. The air conditioner uses 3,500 x 4.4 = 15,400 watt-hours, or 15.4kWh. It’s worth mentioning that air conditioners don’t operate indefinitely. As a result, calculating the wattage per hour will give you an inflated figure. The majority of units will run on a 15-minute cycle twice an hour. As a result, the real power consumption is half of the number, or 7.7kWh when multiplied by two. Multiply the answer by the price of power, say $0.10, to get a daily cost of $0.77.
3. Factors Affecting Air Conditioner Electricity Consumption
Some air conditioners use more energy than others for a variety of reasons. An older model consumes more energy than ones that use new technologies. In addition, if your unit hasn’t been maintained in a long time, it will likely take more energy to maintain the desired temperature in your home.
Energy usage is determined by the capacity of the air conditioners. The greater the cooling requirements and the higher the AC energy consumption, the larger the unit. The capacity of an air conditioner is measured in British thermal units, or BTUs. For each square foot, you’ll require 20 BTUs on average.
The sort of unit you use will also have an impact on the amount of energy consumed. Split-system air conditioners consume less energy than ducted air conditioners. Energy consumption is also influenced by the brand. The Seasonal Energy Efficiency Ratio, or SEER, will give you a better idea of how energy efficient your unit is. The greater the SEER, the more efficient your air conditioner is. To perform properly, a highly efficient system will not require a lot of electricity. A basic air conditioner should have a SEER rating of 13 to 14. Models with a SEER rating of 25 are still available.
The temperature in your area has an impact on how much energy an air conditioner uses. When the outside temperature is too high, it requires more energy to chill a room. If you live in a hotter climate, you’ll need a more powerful air conditioner, which means more power use.
The number of people in your home is another element that affects your AC power use. The human body produces a lot of heat in general. If there are more people in a house, it will require a larger air conditioner, which will require more power than a house with fewer residents. Additionally, the heat generated by electrical gadgets in your home raises the indoor temperature. As a result, your air conditioner will have to work more to chill the same amount of air, resulting in higher energy use.
4. How to Save Money on Your Air Conditioning Bills
You can reduce the wattage of your air conditioner in a number of ways. First, have an older unit replaced with a more energy-efficient model. During the hot summer months, close your windows and doors to keep the sun from heating up your home needlessly. Your air conditioner will have to work harder to maintain appropriate cooling, resulting in increased energy usage.
Energy usage is also affected by the temperature settings and the length of time your device runs. The majority of homeowners keep their homes cooler than what is considered necessary. To avoid overcooling, set the temperature of your air conditioner to 72 to 75 degrees. Make sure the temperature in the device isn’t more than 8 degrees below the outside temperature.
Continuously running the air conditioner is not a good idea. To save energy, turn it off in the evenings or before going to bed, and turn off heat dissipation devices while not in use. Also, make sure your home is properly insulated to prevent conditioned air from leaking out via cracks.
If your home has cabinets, keep them closed at all times. They increase the volume of air that your air conditioner must cool when they are opened, resulting in excessive power use. Clean or replace your AC filters on a regular basis. A blocked filter inhibits airflow, causing the unit to work harder and consume more energy.
Make a plan to have your air conditioner serviced once a year. Check for refrigerant leaks, blocked coils, and a broken compressor, all of which can reduce the efficiency of your unit. Make sure you get an air conditioner that is appropriate for the size of your home. If you purchase a system that is undersized, it will have to work incredibly hard to meet your cooling requirements. Although an oversized unit will chill your home faster, the extra capacity will result in higher energy consumption.
Although some people believe that running an air conditioner is costly, there are several energy-efficient models on the market today that use less energy than earlier air conditioners. It’s a wise purchase, especially for people who live in hot climates, because air conditioning makes the heat bearable. It’s a good idea to consult a specialist before purchasing an air conditioner. They will examine your cooling requirements and assist you in selecting an appropriate equipment. To guarantee that the air conditioner operates at maximum capacity, it’s preferable to leave the installation to a professional.
How much does one unit cost?
A unit cost is the total cost incurred by a business to manufacture, store, and sell one unit of a product or service. The terms “unit costs” and “cost of goods sold” are interchangeable (COGS). All fixed and variable expenses involved with the production of a good or service are included in this accounting metric.
What is the formula for calculating my electric bill?
How to Work Out Your Electric Bill Calculator for Electric Bills with Examples
- Example:
- Total Units Consumed = 720.
- P x t1000 = E ( kWh)
- Energy Used in Watts x Time in Hours = Consumed Energy.
- Energy Cost is calculated by multiplying the amount of energy used in kWh by the amount of time in hours.
What is the power consumption of a 1 ton air conditioner?
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.
What is the formula for calculating unit per hour?
A unit is measured in kWH, or Kilowatt Hour, as seen on power bills. This is the amount of power or energy that has been consumed. You expend 1 unit or 1 Kilowatt-Hour (kWh) of electricity if you use 1000 Watts or 1 Kilowatt of power for 1 hour. As a result, the reading on the electricity meter reflects the real amount of electricity consumed. Similarly to the odometer on your car, which displays the actual distance traveled, an electricity meter displays the quantity of electricity consumed. So, if a 100-watt bulb is left on for 10 hours, it will use the following amount of energy:
