The Science
How We Calculate AC Size

Our calculator uses real HVAC engineering principles used by professionals — not a simple rule of thumb. Every factor that affects cooling load is considered.

1

Room Volume

Length × Width × Height gives the actual air volume that needs to be cooled.

2

Solar Gain

South/west-facing rooms absorb significantly more heat. We factor in your sunlight exposure.

3

Heat Sources

Each person adds approx. 100W of heat load. More occupants = higher cooling demand.

4

Floor Effect

Top floors absorb roof heat and need 10% more capacity than ground floors.

Common Questions
Frequently Asked
QIs a bigger AC always better?
No. An oversized AC short-cycles (starts and stops too quickly), leaving humidity high and wasting electricity. The right size runs longer cycles and cools more effectively.
QShould I get inverter or fixed-speed AC?
In Kishanganj where summers are long and usage is high, inverter ACs save 30–50% electricity. The higher upfront cost is recovered within 2–3 seasons. We recommend inverter for all rooms used more than 6 hours/day.
QWhy are Hitachi and Blue Star recommended?
Both brands are engineered specifically for Indian climate conditions. Hitachi’s R32 compressor technology and Blue Star’s tropical-optimized coils perform exceptionally even at 45°C+ outdoor temperatures common in Bihar summers.
QHow accurate is this calculator?
This calculator accounts for the primary factors affecting cooling load. For highly unusual rooms (glass facades, server rooms, unusual insulation), an on-site assessment by our team gives a more precise recommendation.

Disclaimer

Results are estimates based on standard HVAC load calculation methods for Indian residential conditions. Actual requirements may vary based on wall insulation quality, number of windows, appliances in use, and local climate variations. Jain Refrigeration recommends a site visit for precise assessment before purchase. We are not liable for decisions based solely on this tool.
