Ductless mini-split systems are one of the most versatile and energy-efficient HVAC solutions available, perfect for South Florida homes without existing ductwork, room additions, converted garages, or homes where traditional ducted systems aren't practical. At Sunnyside AC, we specialize in ductless mini-split installation, repair, and maintenance throughout South Florida. Our certified technicians have extensive experience with premium ductless brands including Mitsubishi, Daikin, Fujitsu, LG, and Carrier. Ductless mini-splits consist of an outdoor compressor unit connected to one or more indoor air handlers via small refrigerant lines that run through a 3-inch hole in the wall. This eliminates the need for bulky ductwork while providing precise temperature control for individual rooms or zones. Each indoor unit operates independently with its own remote control or smart thermostat, allowing different family members to set their preferred temperatures in different rooms—perfect for South Florida homes where cooling needs vary by room orientation and sun exposure. Modern ductless mini-split systems achieve exceptional efficiency ratings of 18-30+ SEER for cooling and 9-12+ HSPF for heating, far exceeding traditional central AC systems. This translates to 30-50% lower energy bills compared to window units or older central systems. Since they don't lose energy through ductwork (30% energy loss is common in leaky ducts), every dollar you spend on cooling goes directly to comfort. Many South Florida homeowners see complete payback within 3-5 years through energy savings alone. Ductless mini-splits are ideal for home additions and remodels (no need to extend ductwork), converted garages or Florida rooms, older homes without existing ducts, supplemental cooling for hot rooms, rental properties or ADUs, and homes where duct installation is impractical. They're also perfect for South Florida's architecture—many homes have concrete block construction, flat or low-slope roofs, and limited attic space where traditional ductwork is difficult or impossible to install. We provide complete ductless mini-split services including free home consultations and system design, new installations (single-zone and multi-zone), system replacements and upgrades, repairs for all brands, seasonal maintenance, smart thermostat integration, and 24/7 emergency service. Every installation includes manufacturer warranties (typically 7-12 years), our workmanship warranty, and ongoing support. We help you access available rebates and financing to make ductless mini-splits affordable for any budget.
