Important: BEE Star Rating Changes for 2026

The Bureau of Energy Efficiency (BEE) has revised star rating criteria for 2026. Air conditioners manufactured before 2026 may now have a lower star rating under the new standards: a 5-star AC from 2023-2025 may become a 4-star, a 4-star may become a 3-star, and a 3-star may become a 2-star.

What this means: These ACs haven't changed - they deliver the same cooling performance and consume the same electricity as before. The rating change only reflects updated BEE benchmarks. An older 5-star AC will still be more efficient than an older 3-star AC.

Full Transparency: We recommend older models only when they offer exceptional value, pricing, or features. We've clearly noted which models meet 2026 BEE standards in our reviews below. Understand ISEER & star ratings to compare models yourself.

How to choose a hot and cold AC

Hot & Cold ACs vs Regular ACs - Worth the Premium?

Hot & cold ACs cost ₹8,000-₹12,000 more than cooling-only models but eliminate need for separate room heaters. They provide efficient heating using heat pump technology, consuming 40-60% less electricity than electric heaters. Ideal for North India (Delhi, Punjab, Haryana), hill stations, or anyone wanting year-round climate control from a single unit. Payback period: 2-3 winters if replacing electric heaters.
Heating Performance Metrics Explained

Heating capacity (measured in kW at 7°C): Daikin 4.8 kW is excellent for rooms up to 150 sq.ft. Operating range: -7°C to 55°C means unit works even in sub-zero outdoor temperatures - critical for Delhi winters. Hot start feature: Prevents cold air blow during initial heating phase. Auto defrost: Automatically melts ice on outdoor unit in freezing conditions. Look for models rated for at least -5°C outdoor operation.
Dual Mode Energy Efficiency

Heating mode typically consumes 30-40% less electricity than equivalent electric heaters due to heat pump technology. Cooling mode ISEER ratings apply only to cooling - heating efficiency measured separately as COP (Coefficient of Performance). Best practice: Use convertible modes (5-in-1 or 7-in-1) to optimize energy usage across seasons. Auto mode switches between heating/cooling based on set temperature and room conditions.
Year-Round Maintenance for Dual Mode ACs

Clean filters monthly during heavy use (summer cooling or winter heating). Annual professional service before each season change. Check outdoor unit drainage in heating mode - condensate forms outside vs inside in cooling mode. Inspect for ice buildup during sub-zero operation. Run unit in opposite mode for 30 minutes monthly to keep both systems functional. Blue Fin coating essential for monsoon/coastal corrosion protection.

Frequently asked questions

What is the heating capacity of a 1.5 ton hot and cold AC in watts?

A 1.5 ton hot and cold AC typically delivers 4,500-5,200 watts (4.5-5.2 kW) of heating capacity. For example, the Daikin FTHT50 provides 4,800W heating output while consuming only 1,500-1,600W of electricity. This is possible because heat pump technology moves heat from outside air into the room rather than generating heat directly, making it 3-4 times more efficient than a standard electric heater rated at the same wattage.

Are hot and cold ACs more expensive to run than cooling-only ACs?

For cooling: Same cost. The 3-star rating applies to cooling mode, so electricity consumption during summers matches equivalent cooling-only 3-star ACs (950-1000 units/year for typical 6-hour daily use). For heating: 40-60% cheaper than electric heaters. Heat pump technology is extremely efficient - these ACs deliver 3-4 units of heat for every 1 unit of electricity consumed (COP 3.0-4.0). A 1500W electric heater consumes 1.5 kW to produce 1.5 kW heat. A hot & cold AC consumes 1.5 kW to produce 4.5-6 kW heat. Overall: Saves money if you currently use room heaters. The ₹8K-₹12K premium over cooling-only ACs pays back in 2-3 winters through eliminated heater electricity costs.

How effective is heating mode in extreme cold like Delhi winters?

Highly effective down to -7°C outdoor temperature for all reviewed models. Delhi's coldest nights rarely drop below 2-4°C, well within operating range. Heating performance factors: Daikin FTHT50: 4.8 kW heating capacity at 7°C outdoor - warms 150 sq.ft room in 15-20 minutes from cold start Auto defrost: All models prevent ice buildup that reduces efficiency in sub-zero conditions Hot start feature: Delays fan until coil warms up - no cold air blow during startup Performance reduction: Heating capacity drops ~20-30% when outdoor temp falls from 7°C to -5°C, but remains effective Real-world Delhi performance: Users report room heating from 8°C to 22°C in 20-30 minutes on coldest January mornings. More efficient and quieter than room heaters.

Can I use hot and cold AC in regions with only mild winters?

Yes, but evaluate your actual heating needs first. Recommended for these scenarios: North India (Delhi, Punjab, Haryana): Definite yes - winters reach 2-8°C, significant heating need Hill stations (Shimla, Dehradun, Manali): Essential - sub-zero winters, year-round climate control needed Central India (Madhya Pradesh, parts of Maharashtra): Worthwhile - occasional 10-15°C mornings benefit from heating Office spaces/hotels: Good investment - maintains consistent comfort for occupants year-round NOT recommended for: South India (Chennai, Bangalore, Kerala): Winters rarely below 20°C - heating rarely needed, save ₹8K-₹12K on cooling-only model Coastal regions with mild winters: If winter temps stay above 18°C, stick to cooling-only AC If you already have central heating: Dual functionality redundant Decision rule: If you use a room heater for more than 30 days/year, hot & cold AC pays for itself. Less than that, save money with cooling-only model.

What is COP rating in hot and cold AC and why does it matter?

COP (Coefficient of Performance) measures heating efficiency. A COP of 3.0 means the AC produces 3 kW of heat for every 1 kW of electricity consumed. Higher COP = lower heating bills. Typical COP values for hot and cold ACs in India: 2.5-3.5 at 7°C outdoor temperature (Delhi winter average) and 1.5-2.5 at -7°C. For comparison, an electric room heater has a COP of exactly 1.0 (1 kW electricity = 1 kW heat). So a hot and cold AC with COP 3.0 is 3 times cheaper to run than a room heater for the same heat output.

What is the minimum outdoor temperature for AC heating mode to work?

Most hot and cold ACs sold in India can operate in heating mode down to -15°C to -7°C outdoor temperature. The Daikin FTHT50 works down to -7°C, while some LG and Panasonic models go down to -15°C. However, heating efficiency drops as temperature decreases. At 7°C (typical Delhi winter), COP is around 3.0-3.5. At 0°C, COP drops to 2.0-2.5. Below -5°C, COP falls to 1.5-2.0. Delhi winters (2-8°C) and North India hill stations are well within the efficient operating range for all reviewed models.

How much electricity does AC heating mode consume compared to cooling mode?

Heating mode typically consumes 10-15% less electricity than cooling mode for the same duration. This is because the heat pump cycle is more efficient when transferring heat indoors (heating) than removing it (cooling) at moderate winter temperatures. At 6 hours daily usage with ₹7/unit electricity rate: Cooling mode (summer, 42°C outside): ~160-170 units/month = ₹1,120-₹1,190. Heating mode (winter, 5°C outside): ~140-155 units/month = ₹980-₹1,085. However, if outdoor temperature drops below 0°C, heating consumption increases and may exceed cooling consumption due to defrost cycles.

Can a hot and cold AC replace a room heater in North India winters?

Yes, a hot and cold AC can fully replace a room heater in North India (Delhi, Punjab, Haryana, UP). Key comparison: A 1500W room heater costs ~₹1,890/month (270 units at ₹7/unit for 6 hrs/day). A 1.5 ton hot and cold AC costs ~₹1,050/month for heating (150 units for same duration). Annual heating savings: ₹3,360-₹5,040 over 4 winter months. The ₹8,000-₹12,000 premium over cooling-only ACs pays back in 2-3 winters. Additional advantages: heats larger area uniformly, no fire hazard, no oxygen depletion, thermostat control, and timer function.

How much does it cost to run hot and cold AC for heating vs cooling monthly?

Monthly electricity cost calculations (assuming ₹7/unit and 6 hours/day usage): Cooling mode (Summer - April to September): ISEER 3.8 average for 3-star hot & cold ACs Monthly consumption: ~160-170 units Monthly cost: ₹1,120-₹1,190 Same as equivalent cooling-only 3-star AC Heating mode (Winter - November to February): COP 3.0-3.5 (3-3.5 units heat per 1 unit electricity) Monthly consumption: ~140-160 units (more efficient than cooling) Monthly cost: ₹980-₹1,120 vs 1500W room heater: 270 units/month = ₹1,890 - Save ₹770-₹910/month Annual cost comparison: Hot & cold AC: ₹7,200 (cooling) + ₹4,000 (heating) = ₹11,200/year Cooling AC + room heater: ₹7,200 (cooling) + ₹7,560 (heater) = ₹14,760/year Annual savings: ₹3,560 with dual-mode AC Payback period: ₹10,000 premium ÷ ₹3,560 savings = 2.8 years

What maintenance is required for dual-mode ACs?

Monthly maintenance (DIY): Clean indoor filter: Remove, wash with water, dry completely before reinstalling. Critical during heavy use (summer cooling or winter heating). Check outdoor unit: Ensure no debris blocking airflow, inspect for ice buildup in freezing weather Drainage check: In heating mode, condensate forms outside (reverse of cooling mode) - ensure outdoor drain isn't blocked Remote battery: Replace batteries annually Seasonal professional service (₹800-₹1,500): Before summer (March/April): Deep clean indoor coil, check refrigerant levels, test cooling performance, inspect electrical connections Before winter (October/November): Test heating mode, verify auto defrost functioning, check reversing valve operation, inspect for wear Best practices for dual-mode longevity: Run opposite mode monthly: Even in summer, run heating mode for 30 minutes/month to keep system functional Don't switch modes rapidly: Wait 5 minutes between heating and cooling mode switches Annual gas check: Refrigerant leaks more common in dual-mode ACs due to reversing valve - annual pressure check recommended Coastal areas: Models with Blue Fin/Ocean Black coating need less frequent maintenance due to corrosion resistance Service cost: ₹800-₹1,500 per professional service. Budget ₹2,000-₹3,000/year for two seasonal services.
