Duct free air conditioners make your home's individual rooms or other small spaces more comfortable. Remember, just like whole-home systems, the higher the SEER and HSPF ratings, the more efficient they will be.

We offer a variety of through-the-wall packaged terminal air conditioners (PTAC) and duct free heating and cooling systems to meet any individual room's needs.

What is Duct Free?

For decades, split-zoning air-conditioning and heat pump systems have been the quiet solution for cooling and heating problems around the world. Our quiet and powerful systems have three main components: an indoor unit, outdoor unit, and remote controller. Installation is as simple as mounting the indoor and outdoor units, connecting the refrigerant lines, and making a few electrical connections.

Why Mitsubishi Electric Ductless Systems?

Mitsubishi Electric is the industry leader in split-ductless air-conditioning technology - period. Compare and you'll see that no one surpasses the Mitsubishi Electric brand's performance for quiet, easy-to-use, and energy-efficient operation. And because our split-ductless technology carries the Mitsubishi Electric name, you know every product is built to last. The bottom line is, Mitsubishi systems deliver the ultimate in comfort control for your home or office. It's true today and will be comfortably evident for years to come.

Where Can Mitsubishi Electric Ductless Products Be Used?

If a room is too hot or too cold, Mitsubishi Electric Cooling & Heating can handle it! Mitsubishi split-zoning systems are specifically designed to improve the comfort level in an uncomfortably hot or cold room of an existing building. Because they don't require ductwork, they're the perfect heating and cooling systems for renovating older buildings that were constructed before air conditioning was available - even those with plaster walls and brick facades. The versatility and variety of applications for Mitsubishi Electric systems are virtually unlimited. They're an excellent choice for almost any spot cooling or heating situation, including enclosed sunrooms, upstairs bedrooms, classrooms, hospitals, nursing homes, restaurants, hotels, workout rooms, computer rooms, offices and churches.

They're also equipped with an anti-allergen filter and prevent the cross-flow of air with contaminants. And because they can be controlled by zone, it's easy to set the controls for the exact room temperature you want.

How does it work? Mitsubishi Electric Cooling & Heating can fit into almost any space because their innovative engineering optimizes the capabilities of the INVERTER technology and R410A refrigerant for more efficient systems with smaller indoor and outdoor units. R410A refrigerant is environmentally friendly, with zero Ozone Depletion Potential (ODP). The units themselves are also made of recyclable materials.
