What You Need to Know Before Choosing Your Air Conditioning System
1. Room Size
One of the most important factors when choosing an air conditioning system is its capacity, which should be proportional to the area you want to cool or heat.
BTU stands for British Thermal Unit and is the unit used to indicate the cooling (or heating) capacity of an air conditioning system. Therefore, the higher the BTU/h rating of the unit, the greater its capacity to effectively regulate the temperature of a room.
| Room Area | Recommended BTU/h |
|---|---|
| Up to 12 m² | ~9,000 |
| 12–18 m² | ~12,000 |
| 18–24 m² | ~18,000 |
| 24–35 m² | ~24,000 |
This table provides an approximate estimate of the BTU/h capacity your air conditioning system should have, based on the size of the room or rooms you wish to climatise.
It is important to note that this is only a general reference. Other factors should also be taken into consideration, such as ceiling height, thermal insulation, sun exposure, the number and size of windows, and the usual number of people in the room.
2. Thermal Insulation
The thermal insulation of your home plays a crucial role in the efficiency of your air conditioning system. Homes with good insulation, such as double-glazed windows, well-insulated walls and properly sealed doors, retain the desired temperature more effectively. This reduces the workload of the system and, consequently, energy consumption.
3. Installation Type
There are several types of air conditioning systems. The two most common options for residential properties are Mono-Split and Multi-Split systems.
- Mono-Split: connects one indoor unit to one outdoor unit, making it ideal for conditioning a single room.
- Multi-Split: connects multiple indoor units (two to five) to a single outdoor unit, allowing you to control the temperature independently in different rooms of your home.
4. Energy Efficiency and Savings
The efficiency of your climate control system has a direct impact on your electricity bill. For this reason, it is important to choose efficient solutions, such as Inverter technology, which automatically adjusts the compressor speed according to the needs of the room, instead of constantly switching on and off as traditional systems do.
This technology can help to:
- Reduce energy consumption by up to 30–50% compared with non-Inverter models.
- Maintain a more stable and comfortable temperature, without sudden fluctuations.
- Reduce noise and minimise wear and tear on the system over time.
