Ductless AC: Single- Versus Multi-Zone Cooling

Year-round warm, humid weather in Naples, FL, means you need an effective cooling system for comfort. When you’re adding onto your home, remodeling or replacing an old air conditioning system, ductless AC is a good choice. Here’s what you need to know about single- versus multi-zone cooling for your home.

Single-Zone Cooling

A single-zone ductless AC system has one indoor air handling unit and thermostat. A conduit leads through an exterior wall to the outdoor compressor and condenser unit. When you’re converting an attic or garage into a living space or putting a family room or master bedroom addition onto your home, it’s an efficient choice. It increases design flexibility and reduces energy waste from leaky air ducts.

Multi-zone Cooling

A multi-zone cooling system has up to four air handlers, each with its own thermostat. Each indoor unit also has a conduit, which can be up to 50 feet away from the outdoor unit. This provides plenty of options for placement.

Each indoor unit controls a zone, and each zone can have a different temperature. If you like a cool master bedroom for sleeping, but your other household members prefer warmer bedrooms, set the thermostats to each person’s preference. You can cool just one zone of your home, lowering your utility bills. Multi-zone cooling systems are ideal for new construction, complete home remodeling and homes with no air ducts.

Choosing a Ductless AC System

Ductless cooling systems offer remote control thermostat adjustments and save 30 to 50 percent on your cooling costs. When choosing a ductless AC system, make sure your service technician calculates your home’s cooling needs. An oversized cooling system will short cycle, which wastes energy and shortens the system’s lifespan.

Single-zone cooling systems are an economical choice for home additions and remodeled living spaces. When each person in your household has a different temperature preference, multi-zone cooling allows you flexibility and energy savings.
