4-1 portable air conditioner that’s eco-friendly and low maintenance

When you get the Honeywell MM14CHCS, you’re getting a fan, air conditioner, dehumidifier, and heater. The air conditioner has 14,000 BTU and the heater has 12,000 so both are reasonably powerful and work in small to medium-sized rooms. Taking care of the unit requires very little work on your part, so operating and enjoying this Honeywell is hassle-free.

14,000 BTU air conditioner and 12,000 BTU built-in heat pump

As a 4-in-1 machine, you get a portable air conditioner with 14,000 BTU, and a heat pump with 12,000 BTU. The fan mode has three speeds, so you can either very quickly cool a room (and deal with a little more noise) or keep it low for a more relaxing, soothing vibe. Because of its size and power, it’s ideal in a room up to 550-square feet.

Digital LED display

All four functions are controlled with the digital LED display. The buttons include an automatic on/off and a programmable timer so you can choose exactly when you want the air conditioner/heater to turn off or on. You get a remote control as well, so you can operate everything from a distance.

Auto-Evaporation system

Maintaining the MM14CHCS requires almost no work. Instead of having to manually empty a bucket, the air conditioner has an auto-evaporation so all the water is taken care of on its own. You can run the unit all day and night without having to take time to drain the water yourself.


Effective dehumidifier

The dehumidifier on the Honeywell MM14CHCS can pull around 80-90 pints of water from the air per day. This puts it on par (or above) with units that are just dehumidifiers, so you’re getting a lot of bang for your buck with this 4-in-1 deal. If you use it as an dehumidifier you have to attach the drain pipe to get rid of the captured water.


Many air conditioners are not good for the environment. They not only consume a lot of energy, but they use ozone-depleting refrigerant to cool your home. The Honeywell 14,000 BTU uses RA10A, which is eco-friendly and does not contribute to global warming like other refrigerants do.

Provides extra heat source

This air conditioner is unique because it’s also a heater. You can use the air conditioner during the summer, and the heater in the winter. The heat pump can be used as a supplemental heat source when it’s above 45 Fahrenheit outside.


Has trouble cooling very hot rooms

Most portable air conditioners aren’t great in especially hot climates or rooms that get baked in sunlight and humidity. This Honeywell doesn’t have enough power to make you feel really comfortable. You’ll feel the cooling work best in smaller rooms that don’t get really hot.

Overall Review

As a 4-1 unit, you can use the Honeywell MM14CHCS 14,000 BTU portable air conditioner all year round. It’s an air conditioner, fan, heater, and dehumidifier. The dehumidifier in particular works very well, which is ideal if you’re dealing with a lot of humidity. You don’t even need to empty the water it pulls from the air because of the auto-evaporation system. Because of its power, the air conditioner and heater both work all their best in smaller rooms.
