Frequently Asked Questions

AI
BTU (British Thermal Units) measures cooling capacity. Generally, a 5,000 BTU unit is suitable for small rooms up to 150 square feet, while 8,000 to 10,000 BTUs are better for medium to large rooms. Choosing a unit that is too powerful for your room will lead to inefficient cooling and poor dehumidification.
Smart features, such as app control and Alexa/Google Assistant compatibility, offer convenience and especially useful for those who want to adjust temperatures from another room or set schedules. However, if you only need basic cooling, a mechanical unit is often more durable and simpler to operate.
Mechanical units use dials and knobs, which are often more reliable over the long term and easier to operate. Digital units typically offer more precise temperature control, remote controls, and additional modes like 'Eco' or 'Sleep' mode for better energy management.
