What is a Ductless “Mini-Split” and How Does It Work?

Instead, they rely on an electric refrigeration system “split” between an outdoor unit and an indoor air handler that moves hot and cold temperatures between the indoor and outdoor units via metal tubing.

These compact HVAC systems can maintain different temperatures in different rooms and keep individual members of your household comfortable at the temperature they like best, year-round even in sub-zero temperatures.  

Ductless “Mini-Splits” are Electric Heating & Air Conditioning Systems that don’t use a network of air ducts or burn any fuel.

What Are Some of The Benefits of a Ductless “Mini-Split” Heating & Cooling System?

Lower energy costs, improved air quality, has zero emissions, is extremely quiet to operate, and can be installed virtually anywhere.

Mini-Split Systems require less energy to operate than traditional HVAC Systems and slash your monthly energy bill by eliminating expenses associated with burning fuel and the need to push air through long, outdated ducts to heat or cool the entirety of your home.

Ductless “Mini-Splits” systems are a modern, incredibly efficient HVAC technology that provides superior comfort for every member of the household.

Comfort & Flexibility

Make each room in your home the perfect temperature for its occupants year-round.

Efficiency & Savings

Slash your energy bill with all-electric, incredibly efficient systems. 

Better Air Quality

Improve your family’s health. Breathe cleaner air with no mold, dust, or funky odors
