Power consumption of a 1.5-ton AC

A 1.5-ton AC usually consumes between 1.2 and 1.8 units of electricity per hour, depending on its star rating, inverter technology, and usage conditions. Choosing an energy-efficient model and using it correctly can help lower your electricity bills.

• Most 5-star inverter ACs consume around 1.2–1.5 units/hour.
• Many 3-star models use about 1.5–1.7 units/hour under similar conditions.
• Electricity use changes based on room size, outdoor temperature, insulation, thermostat setting, and maintenance.
• Popular brands such as LG, Daikin, Carrier, Voltas, Hitachi, and Panasonic offer energy-efficient 1.5-ton models.
• Current prices for 1.5-ton ACs generally range from Rs. 30,000 to Rs. 47,000, depending on the brand and features.

You can also buy a new AC on Easy EMIs at over 1.5 lakh partner stores across 4,000 cities, including Reliance Digital, Croma, and Vijay Sales.

The electricity consumption of a 1.5-ton AC depends on its energy rating, compressor technology, room conditions, and usage. Most modern inverter models consume between 1.2 and 1.8 units of electricity per hour, although actual usage varies by brand and operating conditions.

A 1.5-ton AC does not consume the same amount of electricity all the time. Its actual power usage depends on several factors, including the AC's energy rating, compressor type, room conditions, and how long you use it. Understanding these factors can help you choose an efficient model and reduce your monthly electricity bill.

The following table shows the latest prices of popular 1.5-ton AC models available in India.

Here's how EER is used to estimate power consumption:

EER (Energy Efficiency Ratio) = Cooling Capacity (in BTU/hr) / Power Consumption (in Watts)

However, to calculate the current, you'd need to know the AC's voltage rating as well. With both EER and voltage, you can use the following steps:

1. Convert BTU/hr to Watts: Multiply the cooling capacity (in BTU/hr) by a conversion factor of 0.9478 to get Watts.
2. Calculate Power Consumption: Divide the cooling capacity (in Watts) by the EER rating of your AC.
3. Find the Current: Divide the Power Consumption (Watts) by the voltage (in Volts) to get the current (in Amperes).

Important Note:

• The EER rating and voltage information can be found on the AC unit's label or user manual.
• This is an estimate, and the actual current draw can vary depending on the operating conditions of the AC.

For a more practical approach, you can estimate the AC's power consumption directly using its EER and tonnage (cooling capacity). Multiply the tonnage by a base value, like 1.5 kW, to get an approximate value in kW. This will give you a general idea of how much power the AC uses.

Star ratings play a key role in determining how much electricity a 1.5-ton AC consumes. Higher ratings mean better efficiency, lower bills, and smarter cooling for long-term savings.

• 1-Star ACs: Consume the most electricity, offering basic cooling but leading to higher monthly power bills.
• 3-Star ACs: Provide balanced cooling with moderate efficiency, suitable for households using ACs occasionally.
• 4-Star ACs: Deliver better energy savings than 3-star units, reducing electricity costs while maintaining strong cooling performance.
• 5-Star ACs: The most efficient option, saving up to 25–30 percent more power annually compared to lower-rated models, ideal for frequent use.

Choosing between inverter and non-inverter 1.5-ton ACs directly impacts electricity usage and long-term savings. The table below highlights how each type performs in terms of efficiency and power consumption.

Using the right thermostat temperature and AC settings can significantly reduce electricity consumption while maintaining comfortable cooling. Proper usage habits also help improve the efficiency and lifespan of a 1.5-ton air conditioner.

• Set the temperature between 24 degree Celsius and 26 degree Celsius: This range provides balanced cooling while consuming less electricity compared to very low temperature settings such as 18 degree Celsius or 20 degree Celsius.

• Use eco mode for daily cooling: Eco mode automatically adjusts cooling performance and compressor usage to improve energy efficiency and reduce power consumption.

• Enable sleep mode at night: Sleep mode gradually adjusts the temperature during sleeping hours, helping lower electricity usage without affecting comfort.

• Keep fan speed on auto mode: Auto fan mode allows the AC to optimise airflow according to room temperature, improving cooling efficiency and reducing unnecessary power usage.

• Avoid frequent temperature changes: Constantly lowering or increasing the thermostat forces the compressor to work harder, which can increase electricity bills.

• Use timer settings effectively: Setting automatic shut-off timers prevents the AC from running unnecessarily when the room is already cool or unoccupied.

• Clean AC filters regularly: Dirty filters restrict airflow and force the AC to use more power for effective cooling.

• Use stabilisers and proper voltage protection: Stable power supply helps maintain efficient AC performance and prevents unnecessary energy loss.

Among the models listed, the LG AI Convertible 6-in-1 5 Star Split AC has the lowest power consumption at approximately 1.2 units per hour under standard operating conditions. Other 5-star inverter models from Panasonic and Carrier also offer excellent energy efficiency, making them suitable for homes where the AC is used for long hours.
