Ductwork can be expensive to install and takes up more space than most homeowners would like. Echelon and LX Series ductless air conditioners and heat pumps from Coleman, a brand of Johnson Controls, are Energy Star certified and feature a 16 SEER to 27 SEER rating. A more compact and efficient alternative to central air conditioning, the ductless mini-split systems allow users to set temperature and humidity levels for each room in a house to maximize comfort while minimizing energy use. Their advanced compressor technology modulates the system to use only the electricity needed to heat or cool to a preset temperature. The systems also feature a wireless remote controller with a built-in temperature sensor. colemanhvacdealer.com
