Power Consumption of 1-ton ACs

A 1-ton air conditioner consumes between 0.6 and 1.0 unit of electricity per hour depending on its BEE star rating and compressor type. Choosing a 5-star inverter model lowers overall daily power consumption and reduces monthly utility bills.

• Prices for 1-ton air conditioners range from Rs. 25,000 for 3-star split models to Rs. 45,000 for 5-star inverter models.
• A 1-ton 3-star AC consumes approximately 0.9 to 1.0 unit (kWh) per hour of continuous running.
• A 1-ton 5-star inverter AC consumes about 0.6 to 0.7 unit (kWh) per hour under typical room conditions.
• Running a 1-ton 5-star AC for 8 hours daily costs roughly Rs. 40 to Rs. 45 per day at Rs. 8 per unit.
• Inverter compressors automatically adjust power draw once the target room cooling temperature is reached.

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.

A 1-ton 3-star non-inverter AC draws around 1,000 Watts to 1,100 Watts per hour, translating to roughly 1.0 unit of electricity per hour. A 1-ton 5-star inverter AC draws between 600 Watts and 700 Watts per hour on average once the room stabilizes. Over an 8-hour daily period, a 3-star 1-ton AC uses approximately 7.2 to 8.0 units of electricity. A 5-star inverter AC uses about 4.8 to 5.6 units over the same duration, saving nearly 2.4 units per day.

Choose your preferred model, then use the Bajaj Finance Insta EMI Card or Bajaj Finance Easy EMI Loan to finance it. Convert the cost into Easy EMIs that suit your monthly budget and enjoy zero down payment on select models. Check your loan eligibility online in minutes so you know exactly what you can get before you step into the store.

A 1-ton AC is designed for rooms up to 150 sq. ft. Installing a 1-ton AC in a room larger than 150 sq. ft. forces the compressor to run continuously at maximum capacity, increasing power consumption by up to 30%.

Matching room size to AC capacity prevents overworking the compressor. Proper sizing maintains fast room cooling while keeping your daily power consumption low.

Several environmental and mechanical factors influence how hard your air conditioner's compressor works to maintain cooling. The list below details key variables that increase or decrease the daily power consumption of a 1-ton air conditioner.

• Target temperature setting: Setting your AC to 24 degree Celsius instead of 18 degree Celsius reduces compressor workload, cutting electricity consumption by up to 24%.
• Room insulation and leaks: Unsealed doors, windows, and direct heat exposure increase heat ingress, forcing the compressor to run continuously at full power.
• Inverter vs non-inverter technology: Inverter ACs adjust motor speed variable-style instead of switching off and on repeatedly, consuming up to 30% less electricity.

Trade-off note: A 1-ton 5-star inverter AC costs around Rs. 5,000 to Rs. 8,000 more upfront than a 3-star model, but it recovers this price difference within two to three years of daily summer usage through lower monthly power bills.

Your set temperature is the primary factor affecting your 1-ton AC electricity bill. Setting the temperature to 18 degree Celsius instead of 24 degree Celsius increases power draw by up to 36%.

• Temperature setting: Setting the thermostat to 24 degree Celsius saves 6% to 8% power per degree raised above 18 degree Celsius.
• Daily usage duration: Running the unit for 12 hours instead of 8 hours increases daily electricity consumption by 50%.
• Compressor technology: Inverter ACs adjust motor speed to consume 30% to 50% less power than fixed-speed models.
• BEE Star rating: A 5 Star AC uses ~25% less electricity than a 3 Star AC of the same 1-ton capacity.
• Room heat load: Poor room insulation, high ambient outdoor heat (above 40 degree Celsius), or unsealed doors increase compressor workload.
• Filter maintenance: Clogged air filters reduce airflow efficiency, increasing energy consumption by 5% to 15%.

A 1 ton 3-star AC consumes approximately 0.9 kWh per hour, serving as the standard baseline for household cooling calculations. The table below breaks down hourly, daily, and monthly electricity draw along with estimated running costs across BEE star ratings.

Note: Values are approximate. Confirm on your AC's BEE energy label.

You can reduce 1-ton AC power consumption by up to 30% by following six simple habits during daily use:

1. Set thermostat to 24 degree Celsius: Keeping target cooling at 24 degree Celsius saves 6% electricity per degree compared to setting it lower at 22 degree Celsius.
2. Use Sleep Mode overnight: Sleep mode increases target temperature by 1 degree Celsius every 2 hours, cutting night-time power draw by 15%.
3. Clean filters every 15 days: Clean air filters maintain smooth airflow, preventing a 10% efficiency drop caused by dust buildup.
4. Upgrade to an inverter model: An inverter AC saves 30% to 50% power compared to older fixed-speed non-inverter units.
5. Combine with a ceiling fan: Running a ceiling fan at low speed circulates cool air faster without lowering thermostat settings.
6. Seal door and window gaps: Stopping cool air leakage prevents your compressor from running constantly at 100% capacity.

Inverter technology reduces 1-ton AC power consumption by 30–50% compared to fixed-speed models by continuously adjusting compressor speed instead of switching it off and on repeatedly. A 1-ton inverter AC uses a variable-speed compressor that throttles power draw between 300 W and 1,000 W once the target temperature is reached, yielding higher BEE ISEER ratings above 4.5. The table below contrasts key operational specifications between inverter and non-inverter 1-ton air conditioners.

Trade-off note: Inverter models cost Rs. 5,000 to Rs. 15,000 more upfront than non-inverter units, but these savings are fully realised over 2 to 3 years of regular summer use.

Bajaj Finance offers two financing options at over 1.5 lakh partner stores across 4,000 cities in India. Here is how they compare:

How to choose? Both options require you to be physically present at a partner store. The Insta EMI Card is ideal for shoppers who want to purchase across multiple categories over time. The Easy EMI Loan suits buyers looking to finance a higher-value purchase in a single transaction.

Buyer scenario: Rahul, a 35-year-old working professional from Pune, wanted to buy a 1.5-ton inverter AC priced at Rs. 42,990 before summer. Rather than paying the full amount upfront, he explored financing options at a participating retail store. He compared the Bajaj Finance Insta EMI Card, which offers a card loan offer of up to Rs. 3 lakh, with the Bajaj Finance Easy EMI Loan, which offers financing of up to Rs. 5 lakh. Rahul chose a 12-month repayment plan that suited his monthly budget. Assuming zero interest and no additional charges, his illustrative EMI would be around Rs. 3,583 per month. Before completing the purchase, he checked his eligibility, applicable fees and repayment terms.

The process is simple and typically takes 10 to 15 minutes once you are at the store.

1. Browse models on Bajaj Mall: Compare options on Bajaj Mall before visiting a store.
2. Find a partner store near you: Use the Bajaj Finance store locator to find a nearby partner outlet such as Croma, Vijay Sales, or other authorised retailers.
3. Check the AC in person: Check the key features, specifications, size, and performance to choose the product that best suits your needs and budget.
4. Choose a suitable EMI option: At checkout, ask the store executive about the Bajaj Finance Insta EMI Card or Easy EMI Loan. Confirm available tenure options and whether your chosen model comes with a zero down payment offer.
5. Complete payment and schedule installation: The in-store process is quick, and most partner stores offer installation as part of the purchase.

You can also check your loan eligibility online in advance by entering your mobile number and OTP, helping you plan your purchase better before visiting the store.
