What type of heating system may provide both heating and cooling?

• A. Baseboard heaters
• B. Radiant floor heating
• C. Ductless mini-split systems
• D. Electric space heaters

Answer: (C)

Ductless mini-split systems are an excellent choice when considering a heating system that can provide both heating and cooling. These systems consist of an outdoor unit and one or more indoor units, allowing for both functions without the need for ductwork. In heating mode, the system extracts heat from the outside air and transfers it indoors, while in cooling mode, it reverses the process and removes heat from the indoor air, thus effectively cooling the space.

This dual functionality makes ductless mini-split systems particularly versatile for year-round climate control, making them suitable for various applications in different climates. Other systems listed do not offer this combined capability, as they are specifically designed for either heating or cooling rather than both.
