Jefferson Tools JEFPAC12 12000 Btu Portable Air Conditioner Dehumidifier Air Cooler Heater

Maintaining a comfortable indoor environment isn’t just about cooling — it’s about control, flexibility, and efficiency. The Jefferson JEFPAC12 12,000 Btu/hr Portable Air Conditioner, Dehumidifier, Air Cooler, and Heater is designed to deliver all four in a single compact unit, making it a practical solution for homes, workshops, offices, and spaces where permanent air conditioning installation is limited.

With 12,000 Btu/hr of cooling capacity, this portable unit is well suited to single rooms such as bedrooms, kitchens, computer rooms, garages, and small workspaces. In addition to cooling, it also functions as a heater, dehumidifier, and ventilation fan, allowing year-round climate management from one appliance.

Smart, user-friendly control

The unit features an LED digital display with electronic touch controls, allowing easy temperature adjustment and mode selection. A built-in timer and sleep mode help optimise energy use, while the automatic restart function ensures the unit resumes operation following a power outage. A remote control is included for added convenience.

Efficient and environmentally responsible

Using R290 refrigerant, the Jefferson JEFPAC12 offers efficient performance with minimal environmental impact. R290 has zero ozone depletion potential, making it a more environmentally friendly alternative to traditional refrigerants. A self-evaporating system improves efficiency by reducing the need for manual water drainage during cooling operation.

Designed for reliability and safety

An automatic shut-off function activates when the internal tank is full, protecting the unit from overflow. The auto defrost function ensures reliable operation in lower ambient temperatures, particularly when used in heating mode. Pressure limits and heat exchanger tolerances are designed to support safe long-term operation.

Easy to install and move

The unit includes a full window installation kit, allowing quick setup without permanent modification. Caster wheels provide smooth mobility, making it easy to move the unit between rooms as needed.
