How to choose between them

Size to the room first: the ENERGY STAR chart, adjusted for sun, ceiling height and climate, decides the BTU. Our BTU calculator does it for you and lists the systems in range.

One large head suits a single open space; a home of separate rooms is usually better served by a multi-zone system or several small heads.

Rankings follow the rule and order stated above, using makers' published specifications and listed prices. How we research · Disclosure
