Ductless Mini-Split Air Conditioning

What is a ductless mini split, and how can they help me save on energy cost?

A ductless mini split is a heat pump system ideal for the warm temperatures in the Bryan/College Station area as it can draw hot air out of the home through the indoor unit and expel the heat through the outside unit. On cooler days, the system can reverse its direction, keeping your home at a comfortable temperature. This specific system requires minimal labor costs for installation due to its independence from complex ventilation systems, and it allows you to air condition or heat any room independently of the others.

Ductless systems are designed to meet the cooling and heating demands of large, high demand spaces. They provide powerful comfort, particularly in harsh conditions, while maintaining the efficiency you expect
