How much Electricity Consume in 5 Star AC
Many people want to know How much Electricity Consume in 5 Star AC actually consumes when it runs for long hours. In this test, a Blue Star 1.5 Ton 5 Star Inverter AC was operated during night and day to check cooling performance and power consumption. The AC was tested for 8 hours at night and also continuously for 24 hours to understand real electricity usage.
The room temperature, outdoor temperature, running load, and electricity units were recorded during the test. The AC was set at 26°C temperature, medium fan speed, and auto swing mode in normal cooling mode. This helped to measure how efficiently a 5 star inverter AC can cool a room while saving electricity.
During the test, the AC gradually increased its load to cool the room quickly and then reduced power once the desired temperature was achieved. This is the main reason inverter ACs are considered energy efficient compared to normal AC models.
The test also shows that electricity consumption depends on many factors such as room size, heat sources, outside temperature, and airflow. Because of these conditions, the same AC model may perform differently in different rooms.
This article explains the electricity consumption, compressor working, cooling performance, and energy efficiency of a 5 star AC based on the recorded test data.
1. Starting Performance and Initial Power Load
When the AC was turned on, the outside temperature was 34.5°C and the room temperature was 32.7°C, which means the room was already very warm.
Initial Cooling Load
After turning on the Blue Star 1.5 Ton 5 Star Inverter AC, the AC first started running at a low load. The energy meter showed around 560 watts load at the beginning with an input voltage close to 227 volts.
Inverter AC technology does not immediately run at full power. Instead, it slowly increases the compressor speed. Because of this gradual increase in load, the electrical wiring, socket, and meter do not experience sudden heavy power demand.
After a few minutes, the load increased to 900 watts and then above 1000 watts. This happened because the AC compressor tried to cool the room as quickly as possible. Once the desired temperature was reached, the power consumption began to decrease.
Inverter AC Power Adjustment
The important feature of inverter technology is automatic power adjustment. When the room temperature reaches the set value of 26°C, the compressor does not stop completely. Instead, it reduces its speed and continues running at lower power.
During the test, the running load gradually reduced from 1000 watts to around 350 watts. This shows how inverter AC systems maintain cooling while using less electricity. Because of this technology, inverter ACs are promoted as energy-efficient cooling systems.
2. Electricity Consumption in First 8 Hours
The first part of the test measured electricity consumption during 8 hours of night operation.
First Two Hours Consumption
After two hours of operation, the room temperature dropped to 26.8°C while the outside temperature remained around 31.4°C. At this time the AC load reduced to around 350 watts and current around 1.75 amps.
In the first two hours, the AC consumed 0.85 units of electricity. This is considered good performance because the AC had already cooled the room and now needed less power to maintain the temperature.
When the room temperature remains stable and there are no additional heat sources inside the room, the AC consumes less electricity. This shows that removing heat sources in an AC room can improve energy efficiency.
Four Hour Performance
After four hours, the electricity consumption reached 1.35 units. Between 1 AM and 3 AM, the AC used only 0.5 units, which indicates that the compressor sometimes turned off during this period.
When the desired temperature is maintained and no additional cooling is required, the inverter AC compressor may stop temporarily. Once the temperature increases slightly, the compressor starts again to maintain cooling.
3. Electricity Consumption After 6 and 8 Hours
The next part of the test recorded power consumption after six hours and eight hours.
Six Hour Consumption
At around 5:00 AM, the outdoor temperature dropped slightly to 29.7°C and the room temperature remained close to 26°C. The running load was still around 350 watts with about 1.7 amps current.
During the two hours between 3 AM and 5 AM, the AC consumed only 0.41 units of electricity. This brought the total consumption to 1.76 units in six hours.
The reason for this low consumption is that the room had already reached the desired temperature. Once cooling is achieved, the inverter AC reduces compressor speed and uses less electricity.
Eight Hour Total Consumption
By 7:00 AM, the total electricity consumption reached 2.09 units for the full 8-hour operation. Between 5 AM and 7 AM, the AC consumed only 0.33 units.
At this time the compressor had turned off because the room temperature was already lower than the set temperature. The running load dropped to around 15 watts, which means only the indoor fan was operating.

4. Electricity Consumption in 24 Hour Continuous Test
To check the long-term power usage, the same Blue Star 1.5 Ton 5 Star Inverter AC was operated continuously for 24 hours.
First 12 Hours Consumption
When the AC started at 10:00 AM, the outdoor temperature was 36°C and the room temperature was around 33°C. During the first few minutes the load increased gradually from 640 watts to about 1150 watts as the compressor worked harder to cool the room.
After 4 hours, the AC consumed 2.84 units while maintaining the room temperature at 26°C. By 8 hours, total consumption reached 5.42 units.
After 12 hours, the electricity usage increased to 6.94 units. As the outside temperature decreased in the evening, the power consumption also started decreasing.
Full Day Consumption
The AC continued running overnight and reached 8.15 units after 16 hours. When the room remained cool and the outdoor temperature dropped, the compressor worked at lower speed.
After 20 hours, the total consumption reached 9.08 units. Finally, after completing the 24-hour test, the total electricity consumption was approximately 10 units.
The average consumption during the test was 0.41 units per hour, which clearly shows the energy efficiency of a five-star inverter air conditioner.

5. Factors That Affect AC Electricity Consumption
The electricity consumption of an air conditioner does not depend only on the model.
Room and Environment Factors
Several factors influence AC performance such as room size, room design, floor level, sunlight exposure, and furniture inside the room. If the room receives direct sunlight or has many heat-producing devices, the AC will consume more electricity.
Other factors include the number of people in the room, computers or electronics generating heat, and whether doors or windows are frequently opened.
AC Settings and Installation
AC settings also affect electricity consumption. Temperature setting, cooling mode, fan usage, and voltage stability all influence power usage.
The placement of indoor and outdoor units, as well as the distance between them, can also change AC performance. Because of these conditions, the same AC model may show different electricity consumption in different locations.
