Professional ductless mini-split installation for homes and businesses. Energy-efficient zone cooling without ductwork.
Professional Ductless Mini-Split Installation
- Zone Cooling — Ductless mini-splits provide independent temperature control for each room or zone. Perfect for additions, garages, converted spaces, or homes without existing ductwork. Each indoor unit operates independently, so you only cool the spaces you’re using.
- Energy Efficiency — Mini-splits are among the most efficient cooling systems available, with SEER2 ratings up to 30+. They avoid the energy losses associated with ductwork (which can account for 25-30% efficiency loss in traditional systems).
- Flexible Installation — Mini-splits require only a small hole through the wall for the refrigerant lines. This makes them ideal for historic homes, room additions, sunrooms, garages, and spaces where ductwork isn’t feasible.
- Heating & Cooling — Many mini-split systems provide both heating and cooling, eliminating the need for separate systems. Heat pump models can efficiently heat your home even in cool temperatures.
- Top Brands — We install leading mini-split brands including Daikin, Mitsubishi, Fujitsu, and LG. Our technicians are factory-trained on all major manufacturers for warranty-compliant installations.
