How to Choose the Right AC Capacity for Every Room in Your Home

In a city like Islamabad—especially areas like PWD, where summers can be unforgiving—an air conditioner isn’t a luxury anymore, it’s a necessity. But choosing just any AC won’t guarantee comfort or efficiency. One of the most overlooked yet crucial aspects of buying an air conditioner is selecting the right capacity based on the size and purpose of your room.

At Jalal Electronics, we’ve guided thousands of homeowners in the PWD community to make informed choices that result in optimal cooling, energy savings, and longer appliance life. Whether you’re cooling a compact bedroom, a mid-sized lounge, or an open-plan office, understanding AC capacity will help you enjoy maximum comfort without skyrocketing electricity bills.

Why AC Capacity Matters

Choosing an air conditioner with incorrect capacity is like buying shoes in the wrong size—it just won’t perform the way it should.

• Underpowered units struggle to cool the space, run continuously, and consume more energy.

• Overpowered units cool too quickly without dehumidifying properly, leading to discomfort and frequent breakdowns.

The key unit of measurement is BTU (British Thermal Unit), which represents the amount of heat an AC can remove per hour. The higher the BTU, the more cooling power the unit has. But bigger isn’t always better—it’s about matching the BTU to your room’s square footage and environmental conditions.

General BTU Guidelines for Room Sizes

Note: These are basic guidelines. Factors like ceiling height, sunlight exposure, number of people, and usage pattern also affect capacity needs.

Room-by-Room AC Capacity Recommendations

✅ Small Bedrooms (100–150 sq. ft.)

For single bedrooms or compact study rooms, a 0.75-ton inverter AC is usually sufficient. It cools the space evenly, consumes less power, and operates quietly.

✅ Master Bedrooms or Medium Rooms (150–250 sq. ft.)

These rooms need a 1-ton AC, especially if they’re frequently used at night or receive moderate sunlight. Inverter models are preferred for maintaining temperature without frequent starts and stops.

✅ Living Rooms & Lounges (250–400 sq. ft.)

Larger common areas where families gather require at least a 1.5-ton AC, sometimes 2-ton depending on ceiling height and exposure to sunlight. Split ACs are ideal here as they offer better aesthetics and more powerful airflow.

✅ Offices & Commercial Spaces (400+ sq. ft.)

For larger open-plan offices or spaces like salons, showrooms, or classrooms, a 2-ton AC ensures consistent cooling. It's better to use multiple smaller units if the layout has partitions, instead of one oversized unit.

Electrolux Air Conditioner: Efficient Cooling with the Right Capacity

When choosing capacity, brand matters just as much. At Jalal Electronics PWD branch, one of our top-recommended options is the Electrolux air conditioner. Designed for durability, power efficiency, and comfort, Electrolux ACs come in various capacities to suit every room in your home.

Whether you need a 0.75-ton unit for a study or a 2-ton model for your living room, Electrolux offers:

• Eco-friendly refrigerants to reduce environmental impact

• Durability and sleek design to match modern interiors

Our staff at Jalal Electronics can help you choose the exact model that matches your room size and energy-saving goals.

What Else Should You Consider?

✅ Room Insulation

Poorly insulated rooms (thin walls, large windows, or exposed roofs) require more powerful units. Installing blinds, insulating curtains, or sealing windows can reduce the cooling load.

✅ Sun Exposure

South-facing rooms or those with large glass surfaces heat up faster and need higher capacity units compared to shaded rooms.

✅ Appliance Heat Load

Rooms with high-power electronics like desktop computers, televisions, or ovens generate internal heat. For such rooms, increase the BTU by 10–15%.

✅ Number of Occupants

More people mean more body heat, which increases the cooling requirement. Add extra BTU if more than 2 people will regularly use the room.
