Ductless Mini-Split Services
Ductless mini-splits are the ideal HVAC solution for precise comfort that you can customize to individual zones. Whether you have a home addition, a two-story home, or a home without ductwork, mini-splits are a great option.
We offer a full selection of ductless mini-split services, including:
Mini Split Vs. Heat Pumps: Which is Better
Should you install a series of mini-splits or a whole-home heat pump to warm and cool your home? It’s a big decision, but there are things to consider before making a choice.
Mini-splits feature an indoor unit and an outdoor compressor. They can provide heating or cooling for a single room and be set up into a zoning system with other mini-splits.
Heat pumps transfer heat from one space to the other to create a cooling or warming effect. These systems can heat or cool the entire home through the air duct system or without air ducts.
Our team can discuss your needs and install the right HVAC system for you.
