When it comes to determining what your AC system’s capacity needs to be, consider the size of the room or space you need to cool:

  • A room within a 120 to 140 square foot range requires 1 ton cooling capacity
  • A room within a 150 to 180 square foot range requires 1.5 ton cooling capacity
  • A room within a 180 to 240 square foot range requires 2 ton cooling capacity

Energy Efficiency

Energy efficiency is a must!

We’ve already mentioned the importance of buying energy efficient products here, and a home AC is one of the appliances that consumes the most energy. So, when buying one, pay attention to the EER (Energy Efficiency Rating) - the more stars it has, the lesser energy it consumes.

Air Quality (a.k.a. Good Filter)

Air quality equals a good filter.

The air quality of an indoor ac unit relies on its filter. A good filter guarantees not only the air quality, but also ensures a better cooling performance.

Did you know a good filter also affects the energy efficiency? It prevents the choking of the evaporator coil due to dust! Learn more about it.

The types of AC systems available are:

  • Split System: There are two parts to this kind of AC, one that’s internal and one that’s external - to exhaust the heat out. They have a low cost installation and provide flexibility.
  • Reverse System: This type offers both heating and cooling system, meaning it will be useful throughout winter as well. In addition, these hot and cold ACs save up 35% more energy than common heaters!
  • Inverter System: These are more expensive, however, they’re much quieter. They stand out because they’re able to vary the temperature of the air instead of stopping and starting again.
  • Multi System: These connect multiple units to a single outdoor condenser. This means you’ll have less ductwork, but all rooms will have the same temperature control.

A reminder: air conditioners with both heat and cool options have separate ratings when it comes to energy efficiency.
