Ductless Air Conditioning

‘Heat pumps’ or ‘Ductless’ systems are cost-effective and energy-efficient cooling for homes and businesses. For older homes or homes with forced hot water systems, a ductless system is an alternative to ducted central air conditioning.  For homes that already have central AC, a ductless solution can help to cool (or heat) spaces that get too hot/cold for your current system to handle.

Energy saving over traditional electric heat is typically as much as 60%.  AND if you need to add cool to a room you can do it WITHOUT expensive duct work.

How Ductless Heat Pumps Cool Your Home

A traditional AC system burns fuel to create cooling, while a heat pump moves cooing into or out of a building. Heat pumps circulate  refrigerant, between an indoor air-handling unit and an outdoor radiator.T he refrigerant is then sent outside and pressurized, which heats it up, and the ambient outdoor temperature cools it. Heat pumps can use the temperatures of either the outdoor air or the ground to provide heat or cool.

According to the Massachusetts Clean Energy Center using these systems vs traditional baseboards can save 60% on electric heat costs.
