How to Choose the Right AC Capacity for Your Indore Home

Updated January 2026

Choosing the right tonnage is one of the most important decisions when buying a new AC. An undersized AC will never cool properly, while an oversized one can cycle too quickly and waste power. These simple guidelines are tailored for typical flats and houses in Indore.

Basic Room Size Guidelines

As a rough thumb rule, rooms up to about 120 sq. ft. may work with 1 ton, 120–180 sq. ft. with 1.5 ton and larger living rooms with 2 ton, assuming normal ceiling height and average sun exposure. Very sunny west-facing rooms or top-floor flats may need one step higher.

Factors That Increase Required Capacity

• Top floor flats with direct terrace heat
• Large glass windows without curtains or blinds
• Rooms that open frequently to balconies or corridors
• Very crowded living rooms during peak hours

When to Ask a Technician for Advice

If you are unsure, sharing room photos and rough measurements with a trusted technician can save you from an expensive mistake. At Coolfix, we regularly help Indore customers pick the right capacity before installation.
