Why Mini Splits Are Bad

However, it has been shown that mini-split installation can also have serious “leaks” as long line sets on the outside of the house can pick up heat in the summer and lose heat in the winter. The result can be significantly higher energy costs than would be expected based upon the rated efficiency of the system.

Are mini splits supposed to run all the time?

Mini splits run nearly all the time. But, unlike forced-air systems, they don’t use nearly as much energy. That’s because ductless heating and cooling systems use low-power modes that maintain the temperature without clicking on and off all the time.

How much does it cost to run a mini split per month?
