Honeywell Portable Air Conditioner -Stay cool. Stay dry.

The MM14CHCS Honeywell Portable Air Conditioner with Heater combines 4-in-1 technology into one sleek body, cooling and dehumidifying areas up to 500 square feet and heating areas up to 400 square feet. With cooling and heating functions in one, this unit is available for year-round use, keeping you cool during hot summers and warm during cold winters. The MM14CHCS features an environmentally friendly refrigerant, auto-evaporation system, a reliable heating and dehumidifying function as well as a traditional three speed fan-only function. The MM14CHCS is a convenient portable air conditioner that delivers optimum cooling, spot heating, dehumidification and fresh ventilation.

The full-function remote control allows you to operate each feature from across the room. Unlike a fixed air conditioner unit, the Honeywell Portable Air Conditioner requires no permanent installation and the smooth-gliding caster wheels provide easy mobility from room to room. What's more, the auto-evaporation system allows for hours of continuous cooling with no water to drain or no bucket to empty (this operation depends on the humidity level at your location). This portable air conditioner comes with everything needed including a flexible exhaust hose and an easy-to-install window venting kit. The window vent can be removed when the unit is not in use.

Depends on what your looking for...

Good unit, but not for heat. The heat uses room temperature, and bumps it up slightly using the heat pump. If it is humid, the pan inside will fill up quick, you will need a continuous drain. A/C is nice and cool. Dehumidifier needs a continuous drain also using a standard yard hose fitting, but works well also.

Its great

Wer have had its four over 2 years. Here in Minnesota the winters get bitter cold and summers hot and humid. This does a great job keeping the kitchen comfortable all year around. It is loud and its a pain to empty the pan in the summer, its a good trade off....i would highly recommend this.

Honeywell MM14CHCS Portable

It's quiet. It appears to work well. We are waiting for the temperature to either go down to a cold level to test the heater or get above 85 to test the air. Time will tell.
