Is 1 Ton AC Enough for Your Room?
If you are buying a 1 ton AC under 20000, room size selection becomes extremely important. A 1 Ton unit is suitable only for small rooms up to 120 sq. ft. Choosing the wrong capacity can increase electricity bills and reduce cooling efficiency. A smaller AC will run continuously and still struggle to cool the room. This increases monthly power usage.
AC Room Size & Capacity Chart
| Room Size (sq. ft.) | Recommended AC Capacity |
|---|---|
| Up to 120 sq. ft. | 1.0 Ton |
| 121 – 170 sq. ft. | 1.5 Ton |
| 171 – 250 sq. ft. | 2.0 Ton |
| Above 250 sq. ft. | 2.5 Ton or Multi-Split |
How to Choose the Best 1 Ton AC Under 20000?
When buying the best 1 ton AC under 20000, focus on essential cooling performance rather than premium features. In this price range, smart comparison prevents unnecessary electricity and maintenance costs.
- Room Size Suitability: Ensure your room is strictly up to 120 sq. ft. Installing a 1 Ton AC in a bigger space leads to continuous running, weak cooling, and higher monthly electricity bills.
- Energy Rating Check: Most options offer 2 Star efficiency. If a 3 Star model fits under ₹20,000, prefer it because it reduces annual power consumption by approximately 80–120 units.
- Copper Condenser Coil: Always choose 100% copper condenser models. Copper improves cooling efficiency, reduces corrosion risk, and lowers long-term servicing costs compared to aluminium condenser alternatives.
- Window vs Split Decision: Window ACs cost less and installation is simpler. Split ACs are quieter but may require additional installation expenses of ₹1,500–₹2,500 in most Indian cities.
- Annual Power Consumption (kWh): Compare yearly electricity usage carefully. Even a 100 kWh difference can impact your annual electricity expense by ₹700–₹1,000, depending on local power tariffs.
- Warranty Coverage: Minimum 5-year compressor warranty is essential. Compressor failure is expensive, and extended coverage protects you from repair bills that can exceed ₹5,000–₹8,000.
- Local Service Availability: Check the brand service network in your city. Easy availability of spare parts reduces downtime, especially during peak summer months when service demand increases.
