9,000 BTU Capacity

A 9,000 BTU system is one of our most popular sizes, typically designed to cool or heat rooms between 350 and 450 square feet. This capacity is perfect for standard bedrooms, nurseries, or small living areas where precision comfort is a priority. Our 9000 BTU systems are available in both 115V and 230V configurations to suit your home's electrical setup. Many customers choose these for multi-zone wall mounts because they offer a whisper-quiet operation that won't disturb your sleep. If you are looking for a high-efficiency Cooper&Hunter unit, this size often features some of the highest SEER2 ratings in our inventory. It is an excellent choice for a balanced mix of power and energy savings.
