Mini Split with HyperHeat
Hello, I have steam heat and when we get those really cold days below say 15F my boiler runs nonstop and has trouble trying to get past 60F . (past 55 in the zero days). I was toying with having a mini split to help on the coldest of days but one AC pro told me that to be honest it won't help on those days? Is this true? I know they say they can heat up to like 30 below but he installs them all the time and says no? Thoughts?
