Ductless Mini Split Heat Pumps, or “Mini-splits” are electric heating and cooling systems that use refrigerant to efficiently capture warmth from the outside air to heat your home. During the summer months, the system can be reversed to capture cool air and provide air conditioning. A single unit, therefore, provides both heating and cooling! This technology has been used broadly in more temperate climates, but recent advances now mean that they maintain 100% efficiency in temperatures down to -15 degrees fahrenheit, in some models. These are now a great heating and cooling option for the Monadnock region.
