If you’re looking for a smart and cost-effective alternative to having a central HVAC system in your Seattle home, you might want to consider the potential of a ductless mini-split system . A mini-split system is a type of HVAC system that works without the ductwork that central systems require to function. Instead, a mini-split system uses an outdoor unit and an indoor unit—connected by wires through a small hole in the wall—in tandem to heat and cool one or more rooms inside your home. Mini-split systems are easy to add to homes that you’ve just moved into, and they’re a terrific way to upgrade your current house as well. If you don’t want to install ductwork, or if your home is small, a mini-split system may be a better option for you than a new central HVAC system. Mini-split systems are one of the most efficient climate control options available, and they are simple and convenient to operate.
