When it comes to minisplit heat pumps, you get to play by different rules. With a traditional split-system heat pump (or air conditioner), thereβs one outdoor unit and one indoor unit. But with minisplits, you have the option of connecting multiple indoor units (aka heads) to a single outdoor unit. Sometimes youβll see this called a multisplit heat pump. Interesting idea, eh? Sounds like it might save money and make things simpler to have only one outdoor unit. But what are the downsides?
