"Jay’s site visit was inspirational. He presented creative ideas and listened to our thoughts and concerns. His enthusiasm was reassuring and we trusted him because he didn’t come across as a “salesy” HVAC owner. His advice and solutions felt sincere and well planned."

So... How do ductless systems work?

The ductless air-conditioning and heating units are made up to 2 components:


  1. Outdoor compressor unit
  2. Indoor air-handling unit


The 2 units are connected by a refrigerant line and uses electricity to transfer heat between outdoor and indoor air by compressing and expanding the refrigerant.


The ductless heat pump collects heat from outside the house and delivers it inside on the heating cycle and vice versa on the cooling cycle.


New technology

ductless technologyEco-comfort technology makes these systems smarter in how they use energy. Larger coils heat faster and the Hot StartTM system doesn’t activate the fan until the desired temperature is reached. This prevents uncomfortable drafts of cold air.


In addition, the i-see™ Sensor automatically detects differences in a room’s temperature and adjusts for greater comfort.


Installation is a breeze

ductless installationInstallation is easy and fast since these ductless systems don’t require any ductwork. The outdoor and indoor units are linked by a refrigerant line which only requires a small hole (about 3”) for the line to come into your house.


The connecting line is available in various lengths so the outdoor units can be hidden on the side or in back of your house.


Why are ductless systems so energy efficient?

They heat (or cool) rooms individually so unoccupied rooms can be set lower or turned off.


Up to 30% of heat can be lost as it travels through ductwork so no ducts mean no wasted energy.
