How to Choose a Kaisai Air Conditioner for Your Home or Office
Choosing the right Kaisai model comes down to three main factors:1. Room size (in square meters)
The rule is simple: 100 BTU per 1 m² of room.- Up to 20 m² (bedroom, small office) → 9000 BTU (Kaisai KCC-09) – 380 €
- 20–35 m² (living room, kitchen) → 12000 BTU (Kaisai KCC-12) – 450 €
- 35–50 m² (large living room, office) → 18000 BTU (Kaisai KCP-18) – 850 €
- Over 50 m² → a multi-split system or the Professional series
2. The room’s conditions
- Sun all day → add 15–20% to the BTU (e.g., 20 m² with sun = 11000 BTU instead of 9000)
- Poor insulation → add 10–15% to the BTU
- Office with lots of computers and lighting → increase the BTU by 20%
3. Budget and extra options
The price rises with features:- Comfort series (380–450 €) – basic functionality, manual control
- Premium series (620–850 €) – Wi-Fi control, antiviral filter, design
- Office series (540–1200 €) – multi-split, maintenance, centralized control

Kaisai FAQ
Will a Kaisai air conditioner work in cold winter weather?
🔽
Yes, Kaisai inverter air conditioners work at temperatures down to -25°C. This means you can use the heating function even in cold weather.

A Kaisai inverter air conditioner (A++ / A+++) uses 1.5–2 kWh in continuous operation. For a 9000 BTU model at full capacity: 900–1200W. At partial load (air conditioner at 50% capacity), consumption is 400–600W. Monthly cost: around 50–100 euros depending on use.
