The 36,000 BTU system is a heavy hitter, providing 3 tons of cooling and heating capacity for spaces up to 1,500 square feet. This is the ideal size for large residential living rooms, small office buildings, or large detached garages. You can explore our 36000 BTU collection to find both ductless and ducted heat pump systems. Many of these units are used in multi-zone setups where several rooms are served by one powerful outdoor condenser. They are frequently paired with concealed duct handlers to provide invisible comfort to multiple nearby rooms. This capacity is essential for anyone dealing with high heat loads and large square footage.
