Keeping cool as summer heats up is simple with home comfort units from Arctic Wind. This through the wall air conditioner has a 12,000 BTU cooling capacity, allowing it to quickly and efficiently cool spaces up to 550 square feet with ease. The supplemental heating function keeps you cozy in the fall but is not meant as a main heat source in the coldest winter months. Set your ideal temperature and keep it there with precise digital controls and an auto mode so the unit will turn on and off as needed to keep the climate consistent. A 24-hour timer is also included so you can create settings so that your living space is cool when you get home from work and school or at bedtime. Forget the stress of finding replacement filters, use the easy tilt-out removable and washable filter in this unit for easy maintenance that will provide years of use. A Follow Me remote puts the thermostat at your fingertips so the temperature remains consistent from across the room.
