The Koldfront wall-mounted air conditioner heater combo features four operational modes, three fan speeds, and four-way directional air vents. Using the 24-hour timer, the unit will adjust temperature continuously throughout the day.
With four operational modes, including a dry mode for dehumidifying, this is an excellent AC-Heater combo. The heat mode will quickly andquietlywarm a chilly room, and the AC mode will bring down thetemperature fast. For overnight use, the low fan speed contributes a subtle white noise that is hardly detectable.
Sleep mode gradually changes the temperature through the night to save energy before returning to the original setting in the morning. The Energy-Saver mode automatically engages the fan for 2 minutes every 10 minutes to keep temperatures down while the compressor cycles.
When properly installed, the Koldfront AC/Heater combo is quieter than standard wall AC units. Using noise damper blocks and making sure it is tightly secured inside the wall cabinet will go a long way in reducing the running noise.

The installation was straightforward and using the Styrofoam centering blocks, and foam padding helped minimize any vibrations and reduced the noise levels. It quickly cooled a 400 sq. ft. room, though the heater was not as strong as the AC and took a while to bring the temperature back up. Sleep mode was beneficial, as the machine runs at a lower setting and is much quieter before returning to full speed in the morning. The controls on the front of the unit and the remote control are very intuitive and easy to figure out.
The Keystone 2 in 1 air conditioner and heater combo provides room cooling and heating through one efficient model. With three fan speeds, three cooling speeds, and one heating speed, this machine will help maintain a comfortable room temperature without sacrificing your energy bill.
The remote control has a built-inthermostat, allowing for a more even room temperature and sending a signal to the AC to cool based on where you stand. You have complete control over the unit with the remote and can adjust the temperature, speeds, and mode. The timer feature changes the unit’s settings and allows you to create the perfect environment throughout the day. The LED Display is easy to read on both the unit and the remote.
The Keystone 2-1 Air Conditioner and Heatercombo will automatically dehumidify up to 2.3 pints per hour and uses this condensate to cool the air compressor coils, reducing outside drip. In addition, the adjustable 4-way airflow makes it easy to direct the cool where you want it to go and helps increase room circulation.
With the many different speeds for each mode, you never have to worry about being ‘too cool’ or ‘too warm’ and needing to see-saw your way to comfort. For example, the unit’s sleep mode gradually increases room temperature after beingactivated and then cools the room back down in the morning.
- 10,000 BTU of cooling power and 10,600 BTU of heating
- Four-way directional air vents provide coverage for 450 sqft
- Remote Control allows for operation from anywhere in the room and has a sensor that detects room temperatures from where you are standing
- LED Display is easy to read
- Remote has a built-in thermostat
- Remote Control can be tricky to figure out
- Instructions are not very clear; professional installation is recommended
We were impressed with the overall build quality of the Keystone 2-in-1 AC. The condenser coil is copper rather than the aluminum usually installed in these machines, providing longer and more stable life. The “follow me” remote Control helped create a thorough cool through the room, and the buttons are large and easy to see. It cooled our 400 sq. ft. room as quickly as the other ACs on the list. With the Auto feature set, the supplemental heater would run in the morning, reduce the chill, and switch to AC mode as the day progressed.
What Are Some Important Features of a Wall Mounted Air Conditioner/Heater?
Any 2 in 1 wall-mounted air conditioner and heater combination will provide cooling and heating for bedrooms, offices, and studies. Air conditioner heater combo wall units are packed with features great for any home. Some models take that to the next level by adding fan-only air circulation mode, and even a dehumidifier setting. All models differ in their settings and capabilities, so always review the user’s manual and specifications before purchasing one for your home.
Many recent AC and heater combos now include features that make them easier to use than ever, such as remote controls and 24-hour programming. Become familiar with any efficiency modes and timers before you make your purchase, as they can help you create the best continuous ambiance in your space while saving you money on your energy bills.
Lastly, consider where the 2 in 1 air conditioner/heater will be mounted, and the traffic pattern of the room. Many of these air conditioner heater combo wall unit models have multi-directional vents that can change the airflow pattern. Make sure the unit you purchase will effectively cool and heat the desired area.
How Do I Choose a Wall Mounted Air Conditioner/Heater?
The most important thing to be aware of are measurements. Not only do you need to be sure that the wall-mounted air conditioner and heater unit will fit in the allotted space where you plan to install it, but it also needs to be able to deliver enough cooling or heating to make the entire room comfortable.
Air conditioner and heater strength is measured in BTU or British Thermal Units. The higher the BTU, the higher the heat or cooling output. Models with a higher BTU will typically provide heating and cooling for larger spaces and can maintain a greater range of temperatures. Check that the wall-mounted ac heater’s heating and cooling BTU is adequate for your space.
Frequently Asked Questions
What are some reasons I might wish to use a wall-mounted air conditioner heater combo?
There are many scenarios in which an AC/Heater combo machine might be a great choice:
- For older homes or apartments without ductwork for central air or heating
- In rooms that don’t receive as much circulation from central air or heating units
- When wishing to keep a different temperature in just one room of the house (such as a nursery or study)
Do wall-mounted air conditioner heater combo units use a lot of energy?
Depending on how frequently you run your ac heater combo unit, and the temperature you select, you may notice a change in your energy bill. Fortunately, most current air conditioner and heater combos include efficiency settings that can reduce this impact, such as timers, sleep and energy saving modes, and more.
What does the timer feature on an air conditioner and heater combo do?
Much like a thermostat can be programmed to control levels of heating and cooling through a centralized unit, these wall-mounted units can also be programmed with a timer. This allows you to maintain temperatures at the desired level all day and night, without manual adjustments. You can save on energy by running it less when you’re not home, or at a different temperature during the night.
You may wish to invest in a wall-mounted air conditioner heater combination to improve the air circulation and temperature in a single room. These ac heater combo units offer a variety of features, including efficiency settings, and programmable timers to allow you to only use as much- or as little- heating and cooling power as needed. Make sure the combo you choose will fit both in the mounting and in the space in which you plan to use it by checking its specifications for measurements as well as BTU.
