Have you chosen the right air conditioner size for your room? Most AC Salesmen in our region try to sell us ACs that are twice as large as they should be. An air conditioner reaches peak efficiency after running for 10 minutes. Buy too big and your air conditioner will shut on and off too often, wasting enormous amounts of electricity while it runs with low efficiency. It will also not have enough time to reduce the humidity of your room, which is crucial to feel cooler.
Before you head out to buy a new air conditioner, first choose the right air conditioner size for your room by using the calculator below. It will choose a size for you based on room size, ceiling height, insulation and shade.

In general, a 0.75 ton (9000 BTU) or 1 ton (12000 BTU) air conditioner is usually big enough for all bedrooms, office rooms or meetings rooms. You may need a 1.5 ton (18000 BTU) or 2 ton (24000 BTU) air conditioner for your living room or classroom.
To compare air conditioner brands and models and find the best air conditioner brand for you, you need one main benchmark. The Energy Efficiency Ratio (EER) is the key to see how efficient the overall performance of the AC is, assuming it is correctly sized. EER is the ratio of the amount of cooling power the air conditioner provides versus the amount of input power it needs to run. The EER has a direct impact on the air conditioner power consumption. The higher the Energy Efficiency Ratio, the more efficient the AC.
Compare air conditioner brands in the table below to find the most energy efficient air conditioner for your needs. We have shown all brands and models that are available in Pakistan. Check back regularly as we add more brands and models to the table. Find the best energy saving air conditioner brand for your needs.
Annual electricity usage and bills calculations make the following assumptions: The AC runs 10 hours daily for 7 months of the year. And the electricity tariff is Rs. 15.62 + tax (the tariff for 300-700units/month).
