The Best Portable Air Conditioner Heater Combo

Choosing the best air conditioner is usually all about making the right calculations based upon the amount of space that you need to cool. Then, you will also need to consider the other factors that affect the quality of an air conditioner, such as its noise levels, its power draw, its moisture disposal systems, etc.

Many apartments and condos do not permit you to have a window air conditioner so portable units are a great option.  They do not need to be permanently installed and the setup is fairly quick and easy. Also, if you’re living in a small space, it’s not ideal to block the natural light that comes in with a window air conditioner.

Take a look at these 4 portable air conditioners that we have listed below, and choose one that fits your needs.  See the one we’ve selected as the best portable air conditioner with heater.

You can’t really go wrong with 14,000 BTU’s of cooling power and 13,000 BTU’s of heat pump prowess, especially when the unit features auto-evaporation. So no more messy bucket runs from the cooler to the sink, neither do you have to attach lengthy pipes to your cooler – instead your air conditioning system will dehumidify the air, and dispose the moisture for free via automatic evaporation through the hot air pipe. You will also get a full-function remote control and an intuitive digital LCD display on the front that clearly shows temperatures, and operating modes.

Speaking of operating modes, the Honeywell MM14CHCS can function as an amazing 14,000 BTU air cooler, a powerful 13,000 room heater, a dehumidifier capable of draining 79.2 pints of humidity daily, or even a standalone fan that can blow air at three different speeds. There is also an automatic on-off timer that can operate within a time range of 24 hours. The machine is extremely quiet despite its size, in fact it is just as silent as the fans on your computer CPU, at just 55 dB-A.

SPT WA-1420H Portable Air Conditioner with Heater

SPT WA-1420H: 14,000BTU Portable Air Conditioner with Heater
View on Amazon

The SPT WA-1420H is a great choice when it comes to portable home and home-office air conditioning, along with heating. The large 14,000 BTU cooling capacity means that this beast can handle areas up to 500 square feet in size, and it comes with 11,000 BTU of heating power to keep you warm even in the coldest winters. It is basically an AC and electronic fireplace rolled up into a single easy to manage, highly compact, and super-efficient unit.

Even though it is rated to perform in areas of around 500-550 square feet, you can stretch that number to around 700 if you don’t really need instantaneous cooling since the machine comes with 3 different fan speeds (low, medium, high) to effectively maintain airflow and noise across areas larger than its stipulated capacity. It has 4 different operational modes – cooling, heating, dehumidifying, and fan. The refrigerant used in this air conditioner is the R410 which happens to be totally eco-friendly. The washable air filter captures dust particles and keeps your air clean, and the built-in water tank lets you attach a hose for continuous moisture drainage.

Choosing the Best Portable Air Conditioner Heater Combo

When selecting the best portable air conditioner with heater, it comes down to three things:

1. They either cool, or heat the air in your room

2. In cooling mode, an air conditioner also sucks away moisture from the air, which may be released back through self-evaporation, or disposed via pipes/trays.

3. It also purifies the air, not as thoroughly as a dedicated air purifier though.

The first function is the most important one – in order to get the right cooler & heater for your room, you absolutely need to evaluate the BTU rating of your future air conditioner. That’s because a lack of cooling power will mean longer cooling times and inadequate performance during the summer, whereas an excess of BTU’s will make the air dry and unhealthy. BTU stands for British Thermal Units, and it is a measurement unit for thermal energy. If you remove thermal energy from the air, your room becomes cooler, while if you add thermal energy it becomes hotter.

Portable Air Conditioner - Summertime

Normally, when an air conditioner plus heater unit is rated at say, “X” BTU’s, it refers to the capacity of the cooling system. The heating system may have a different BTU rating. Many air conditioners with heaters carry a similar cooling as well as heating BTU rating. So here are the approximate BTU recommendations according to room size:

200 square feet: 8000 BTU’s

250 square feet: 9000 BTU’s

300 square feet: 10,000 BTU’s

350 square feet: 11,000 BTU’s

…and so on, adding 1000 BTU’s per 50 square feet of area. For rooms that are shaded, you can subtract 10% from the cooling requirements, and for rooms that receive full sunlight, you may need to add up to 10% in the cooling requirements.

After deciding on the BTU rating for your upcoming air conditioner with heater, you’ll need to look at other factors such as how it disperses the hot air (window pipe, drop through ceiling, wall duct, etc.) and how the condensed moisture is dealt with. A tray or bucket system is common in older or cheaper models, and you should always look for a unit with either a pump based moisture dispenser or a self-evaporating type.

The self-evaporating types release moisture back into the air through an evaporation process and maintain a constant humidity level, and need zero maintenance. The final thing you’ll need to check is the noise levels and the size, i.e., is it compact enough to fit into your dorm room or apartment? Is the noise too loud, or does it interfere with your sleep or other activities? Once these questions are answered, you can go on to select the appropriate model based on your needs.


Portable AC systems vent hot air as a component of the cooling procedure. This hot air is commonly vented out of the space that is being cooled utilizing a hose and can be vented out of a window, roof, sliding glass entryway, or through a divider. Most compact ACs come with a window package that incorporate the required hose and parts.

Windows & Doors
Setting up your hose to work with a window or door is contingent upon the particular model. Keep in mind, a window kit may not cover the full length of the sliding glass door. If required, the crevice should be filled with other material like Plexiglas.

Window Screens
Many people worry about window screens when they think about acquiring a portable AC. Even though hot air will be ventalated out the window, most screens are unaffected due to the hose not extending out from the window.

Single or Double Exhaust Hose
They can be single or double hose for pushing out hot air and drawing air in for cooling. A few models have both choices. Here is some more information on both options:

Single-Hose: Single-hose air conditioners work by taking in air from the room, cooling it, and pushing the majority of the air back into the area. A tiny amount of this air will be utalized to cool the machine and will be pushed out of the exhaust hose. It will create a small amount of negative air pressure as it utilzies air from inside the space to cool the compressor.

Dual-Hose: A dual-hose air conditioner draws in room air, then cools it, and then lets it back into your room. As the unit warms up during this procedure, the intake hose draws in air from the outdoors to cool down the machine. Next, this air is pushed out through another exhaust hose. Because of this, a dual-hose AC unit does not require negative pressure within the area being cooled like single hose units.

Benefits of a Portable Air Conditioner

When the temperature heats up outside, people will do whatever they can to stay cool inside. For most people, this means installing an air conditioner. While a fan works well on cooler days, on hot days, all that a fan will do is circulate the hot air throughout the room. An air conditioner is the only effective way to cool down the house on a hot day.

For years, many people have been using central air conditioning and window units to cool down their homes. There were people who were using portable air conditioners back then and today, more and more people are using them. This is because there are so many advantages and benefits of owning a portable air conditioner.

#1 They Don’t Cost Too Much
Many people are buying portable air conditioners due to the cost. These air conditioners cost much less than having a central air conditioning system installed in the home. Many models can even cost less than window units. There are high-end portable air conditioners that can be very expensive, however, if you shop for lower end models, you should be able to find one that costs less many window units.

#2 There is No Installation Required
If you are going to go with central air, the installation process is very time consuming and very expensive. If you are going to be using a window unit, you would need to lift it into the window, pull the window down, and then crew the necessary parts into the windowsill. If you are doing this in multiple rooms, it can be exhausting. Portable air conditioners don’t need to be installed. All you need to do is find a place for the exit hose to drain and you’re done. Since portable air conditioners are on wheels and they are lightweight, you don’t need to worry about any heavy lifting.

#3 They Are Portable and Convenient
If you are in your bedroom on a hot day, you can use your portable air conditioner in there. If you decide to get up and watch television in the living room, you can simply roll your portable air conditioner out and use it in there. As long as there is a window for the exit hose, you can use your portable air conditioner in any room that you want. Also, you can easily move it from room to room. Most portable air conditioners are on wheels and they are lightweight and easy to carry.

#4 They Are Energy Efficient
When you compare the energy efficiency of a central air conditioning unit and a portable air conditioner, it is no contest. A portable air conditioner uses much less energy. Also, a portable air conditioner allows you to move the unit to the area that you need to have cooled down. This is not an option with central air. If you are only cooling down a small space rather than the entire home, you can save a great deal of money on your energy bills. Since portable air conditioners use less BTU’s than central air, they are the most inexpensive way to cool down your home.

#5 Portable Air Conditioners Dehumidify the Air
When the weather in the summer heats up, the air is often humid. This humidity can make it feel even hotter than it actually is. The good thing about portable air conditioners is that they not only cool the air down, they also dehumidify the air. This is great on humid days. There are also some models that have a setting which will dehumidify the air without cooling it down. This allows you to use the unit all year long to keep the moisture out of your basement.

#6 A Great Option For Basements and Attics
If you have turned your basement into a rec room, a gym, a playroom for the kids, an office, or a spare bedroom, you will need an air conditioner. While the basement is the coolest area of the home, on a hot day, it can still get warm down there. Since most basements have small windows near the ceiling, a window air conditioning unit would not be an option. The same is true if you need to cool down your attic. Most attic windows are much smaller than the average size window and a window unit won’t fit. Also, because heat rises, the attic is going to be the hottest room in the home. If you are planning to spend any time in your attic you will need air conditioning. In this case, the only option would be a portable air conditioner. When you have one, you can make use of the attic regardless of the high temperature outside.

#7 Keep Cool While Camping
There are plenty of great things about camping with friends and family. You can go swimming and fishing in the lake, have a cookout for every meal, and you can roast marshmallows by the fire at night. While there are great things about camping, there are also a few downsides. One of these is the heat. If you are sleeping in a pop-up camper and you cannot sleep in the heat, it can make for a miserable time. If you have a portable air conditioner, it will make sleeping much more comfortable. All you need to do is put the exit house out the window of the camper and you will be sleeping like a baby. If you are handy, you might even be able to rig one up in a tent. After camping with a portable air conditioner once, you will never want to go camping without one again.

It can be impossible to keep cool during the summer if you don’t have an air conditioner. If you are considering buying a window unit or installing a central air conditioning system, you should first consider all of the benefits of buying a portable air conditioner. Not only are they energy efficient and portable, they are also great for rooms where it isn’t possible to use a window unit.
