Ductless mini split Heat Pumps & ACs can be configured with either one or multiple indoor units (multi zone system) powered by a single inverter controlled, variable-speed outdoor unit to bring comfort anywhere in your home, including room additions, sunrooms, and garages. The inverter outdoor compressor ensures maximum comfort in any season by continuously adjusting heating and cooling capacities to meet your specific needs.
Because there are no ducts, installation is a breeze—no tearing open walls, patching, or repainting required! Ductless mini split ACs and heating can be either wall mounted or ceiling mounted, creating a clean look while preserving the easy installation factor of traditional window units. And the outdoor unit powers the indoor units, so there is no need for additional wiring.
Older homes weren’t built to accommodate the ductwork of standard modern air conditioning systems. With a ductless mini split air conditioner, you can preserve the integrity of your home’s architecture without having to carve out spaces for ducts and vents.
By selecting specific rooms to heat or cool, energy use is concentrated in the areas you choose - meaning that you can control the temperature and your energy bill!. Plus, ductless mini split systems can offset the energy loss of older homes by continuously adjusting heating and cooling capacities to best match current conditions, making them a convenient and energy-efficient choice.

Frequently Asked Questions
How many square feet can ductless mini split systems heat/cool?

By how much can a ductless mini split system lower your energy bill?
