Room Heat Load Estimate

Please note: This heat load estimate is based on limited inputs and shouldn't be relied on. It is not a substitute for a qualified H.V.A.C. consultant, undertaking a thorough heat load calculation that includes many other variables. If the heat load estimate falls between two AC unit available capacities, it is recommended to select the larger capacity model.
