Technical Explanation of BTU Discrepancy

Beware of the Mr. Cool Dual mini Split over hype
What happens here
The presenter delves into the technical explanation for the discrepancy. He explains that the system he purchased, despite being advertised as '21,000 BTU,' consists of an 18,000 BTU outdoor condenser (heat pump) and two indoor air handlers (one 9,000 BTU and one 12,000 BTU). He clarifies that the true cooling capacity of the system is determined by the condenser, not the sum of the air handlers. He uses an analogy of a 25-ton unit only doing 10 or 15 tons of cooling to illustrate the misleading nature. He highlights that the MrCool website's product description itself states: "It's essential to note that the total BTU output of the air handlers, when operating together, won't surpass the condenser's 18K BTU Rating." This is his primary evidence of the misrepresentation.
Goal: Explain why the advertising is misleading based on technical specifications.
