Save space and stay comfortable all-year-round with the right reverse-cycle AC

Hong Kong's winters have seen some cold days in recent years. Many people consider buying heaters but hesitate because they are only used for a few days. This is why a reverse-cycle air-conditioner could be your ideal choice. It offers both cooling and heating functions. Continue reading to find out the key factors to consider when selecting one.

Highest Cooling Efficiency ≠ Highest Heating Efficiency

The energy label on a heat pump air conditioner shows separate energy efficiency ratings for cooling and heating.

The Electrical and Mechanical Services Department (EMSD) website lists the Cooling Seasonal Performance Factor (CSPF) and Heating Seasonal Performance Factor (HSPF) for all models available in the market. The higher the number, the better the cooling or heating efficiency.

Remember: The highest cooling efficiency does not necessarily mean the highest heating efficiency. So, when choosing a model, make sure it matches your actual needs — whether you prioritise cooling, heating, or both.

Adequate Airflow for Your Household Size

Many users run their air conditioners for longer hours in the summer, especially in households with more people. Pay attention to the airflow capacity when selecting a unit for you. If the airflow is too low, it might not be cooling enough during the summer days.
