When I asked how many BTUs the quoted HP could move the guy couldn’t tell me. I told him I wasn’t trying to remove horses so that little tidbit of information was kinda important. Eventually I looked up the conversion and also got the manufacturers specs. Later I was told that Daikin instructed them to quote in hp based on room size. No mention of R values, occupancy, windows etc., just room size, so no need for all that other superfluous information. It was a “developing” country.
