Hybrid Systems

Hybrid or “dual-fuel” systems are a great energy-efficient alternative to conventional heating and cooling systems. Just like a hybrid vehicle, a hybrid HVAC system automatically selects the most fuel-efficient method to deliver home comfort. Alternating between an electric heat pump and a fuel-powered furnace, hybrid systems keep your home comfortable in moderate to freezing temperatures.

The Unico System

The Unico System can be used to cool or heat homes or buildings that have no ductwork, inadequate ductwork or little space; or in any application where superior indoor comfort is desired. The Unico System adapts perfectly to any type of residential setting such as homes, condominiums, or apartments. It also adapts to many commercial and industrial applications. It offers a mini-duct system where air is distributed through small 2-inch flexible ducts that fit almost anywhere.

Ductless Split Systems

Mini-Split heating and cooling systems provide individual room temperatures, yet whole-home constant comfort year-round. Systems allow for a peaceful inside environment because components like compressors and motors are installed outdoors. Engineered to install quickly and easily with little to no ducting, these systems provide heating and cooling solutions where others cannot.
