CONS
  • Short-range remote
  • Needs a separate drain bucket    

I can confidently say that SLACHT108 SLPAC is one of the best portable air conditioner and heater combos I’ve come across.

With a 10,000 BTU (British Thermal Units) rating, SLACHT108 efficiently lowers the temperature in medium-sized rooms to the low 70s.

More impressively, it heats the same space less than 30 minutes to 80-82 degrees.

(And it's 12,000 BTU big brother does an even better job.)

Also, the SLACHT108 is energy-efficient. Its EER isn't the highest I've seen, but it's more than good enough for regular use, and it shouldn't add more than $12-15 to your monthly electricity bill.

It's better than models like the Black+Decker BPACT14HWT portable air conditioner but lags slightly behind the Vremi VRM050520N.

Now, the built-in dehumidifier function is a game-changer for me.

I cook at least twice a day, and SereneLife air conditioner removes excess moisture as quickly as any air conditioner I've ever tested.

To be fair, I don't have a drain to connect the AC unit to, so I have to use a bucket, which can be annoying if you live in a humid environment.

SereneLife SLACHT108 SLPAC dimensions
After reading countless reviews, I noticed many people complaining about the noise levels, but in my experience, when running the fans on low, this portable AC won’t exceed the manufacturer's noise levels of 52-56 dB.

Another great feature of the SereneLife air conditioner is its compact design.

This thin unit has solid design features, such as cable hooks on the back, for seamless cable management.

Setting the whole thing up takes less than 5 minutes, including unpacking.

You'll get a window kit you can mount both vertically and horizontally, which means it will fit essentially every window.

Also, the hose is excellent. It'll keep its shape no matter how many times you extend it and put it back.

Also, I can't tell you how happy I was that I got batteries for my remote, even though the remote control doesn't have the best range.

Finally, you can rest assured that you'll be covered with a 1-year warranty.

I've read about a few instances in which people got their unit replaced within two weeks, even if it was just slightly nicked during delivery.

Overall, I really can't say I dislike anything about this product in any way, shape, or form - especially at this price point.

CONS
  • Oddly positioned thermostat
  • Not the best option for heating
  • It can be a bit loud at night

My runner-up is the Vremi VRM050520N, with 12,000 BTUs of cooling ability.

This means that Vremi can cool spaces larger than SereneLife portable air conditioner can, and it can do it slightly faster - despite the Amazon listing stating otherwise.

I tested Vremi in a 400 sq. ft. room, and the temperature drop was immediately noticeable. My thermostat would show low 70s in about 20 minutes of running the Vremi at 67 degrees.

One thing I noticed is that the heating mode output isn’t as efficient.

While it will blow hot air into the room, I haven't been able to warm up my room to 80 degrees, so it would struggle to keep a larger apartment sufficiently warm during harsh winters.

My guess is that since this one has vents and the thermostat on top, they kind of interfere with one another, which makes the AC “think” that the temperature is higher than it actually is, so it will pause earlier than it should.

So, running it on "Auto" is probably not the best if you plan on warming yourself up.

On a more positive note, the timer, remote controller, and all the adjustable settings and modes (cool, fan, dry, and sleep) work great.
Vremi VRM050520N dry mode

The remote is good, and you won’t have to come close to the unit to turn it on or change the temperature.

Another thing I love is you can easily remove and wash the air filter. 

While this won’t save much money in the long run, it will do a lot for air quality, which is more important if you ask me.

Once again, the installation process is quick and hassle-free, and you can set this one up in any room with a horizontally accessible window in less than 5 minutes.

The built-in casters allow you to move the portable air conditioner unit from the living room to the bedrooms (although even in "Sleep" mode, I couldn't entirely phase out the sound during the night).

Finally, this one has a "Dry" mode, a dehumidifier feature, but it isn't as good as the one on SereneLife or Whynther ARC portable air conditioner.

Who is Vremi VRM050520N best for?

Vremi VRM050520N is ideal for those looking for a cost-efficient year-round AC/heater combo.

CONS
  • Misleading marketing
  • Much louder than advertised
  • Not the most effective heating option

First things first, the Black + Decker BPACT12HWT portable air conditioner, with its 12,000 BTU capacity, won't effectively cool up to 500 sq. ft. - despite what the listings say.

Instead, I found Black + Decker BPACT12HWT more efficient for 350-400 sq. ft. spaces.
Black + Decker BPACT12HWT 400 sq ft

To be fair, it heats and cools more effectively than the SereneLife SLACHT108.

From my measurements, it will spew out 43-44 degrees air when you put it on high, so it will be at most 20 minutes before the room is nice and cool.

On the other hand, heating isn't as impressive, but it will warm up your space to 75-76 degrees in most cases. I just wouldn't rely on it during really cold months.

For those freezing months, I'd probably have you go with a 14,000 BTU version of this Black + Decker or pick the TURBRO Greenland, which may be the best portable air conditioner with heater.

What I'll sometimes do with portable air conditioners is set a two-hour timer to fall asleep in a chilly room, but I honestly couldn't do it this time.

I don't mind white noise, but this was just a bit too loud.

While this one is supposedly running at 52 dB, that is untrue. I found it to be significantly louder, and many have claimed it goes over 70 dB on occasion.

On the bright side - the dehumidifier on this model is very good.

Not only will it handle the moisture in the air, but it auto-evaporates the liquid it pools from the room, so you don't have to drain it or empty the tank, which is pretty neat if you live someplace humid, such as Florida.

Finally, the Black + Decker portable air conditioner is not the most energy-efficient in its price bracket, drawing 1.4 kWh at max.

However, that still shouldn't affect your electric bill much. On average, that'll be like $15-20 per month, depending on usage.

Who is Black + Decker BPACT12HWT best for?

Black + Decker BPACT12HWT is one of the best portable air conditioners for everyone looking for a reliable, long-lasting portable air conditioner with heater.

Pros
  • Efficient both cooling and heating
  • Quieter than most units this size/capacity
  • Long-lasting and reliable
  • More powerful than advertised
  • Recycles condensation
CONS
  • Heavier than average dual hose models
  • Preferably run continuously

Unlike the single-hose portable units I've covered so far (like the Vremi), the Whynter ARC-14SH is a dual-hose AC and heater.

In other words, Whyther ARC is a solid choice if you plan on heating or cooling your whole apartment (up to 550 sq. ft.).

In the real world, the Whynter ARC-14SH dual hose system will heat the space in as little as 10-12 minutes.

Useful Note:

Dual hose portable ACs are more efficient at cooling as compared to single hose ACs, but they are more expensive and are difficult to setup.

Cooling is even faster. The ARC takes about 5 minutes to refresh the space and about 15-20 minutes to reach the desired room temperature.

From my experience and what I’ve seen other people say, you can expect up to a 10-degree difference in cooling and an 8-degree difference in heating when using this portable air conditioner.

ARC also features a neat feature that recycles the condensation from the drip tray to help produce cool air faster. In other words, you won't have to empty the drip tray or a bucket like with SereneLife.

On a similar note, you must remove the intake hose once the heating season comes along.

Whynter ARC-14S dual hose

If you don’t, you’ll have to empty the water a few times a day because the temperature difference between indoor and outdoor air is too large and will cause condensation.

Now, I didn't expect such a powerful air conditioning unit to be quiet, but I was pleasantly surprised.

While the start-up noise levels can reach over 60 dB, the noise drops off significantly after a bit.

According to my measurements, once the ARC settles down and, even with the fan on the high setting - the unit resides well below 60 dB.

Still, this air conditioner isn't quiet-as-a-mouse, and you will hear the portable air conditioner running in the room, but you shouldn't need to make your TV louder or shout to be heard.

I suspect this is the case because when the Whyther achieves the "perfect" temperature, it turns off the compressor (which lowers the noise) and just leaves the fan on to circulate cooled air.

This dual hose system only has a 1-year warranty (with a 3-year compressor coverage), but I've used it for years without incident, so rest assured you won't be spending money on repairs.

Who is Whynter ARC – 14SH best for?

Whynter ARC – 14SH air conditioner is ideal for everyone looking for a dual-hose design for an entire apartment or small home.

  • More power than advertised
  • Compact for such a powerful unit
  • The best option for heating on this list
  • Energy-efficient while being budget-friendly
CONS
  • Auto mode could be better
  • A heavy machine

With its 14,000 BTU of cooling power and impressive 13,300 BTU heating output, I witnessed a product that can definitely keep you both cool and warm year-round.

I have had my apartment as chilly as 69 degrees with TURBRO Greenland after running it for an hour, with my room temperature dropping to 72-73 from the low 80s in about 20 minutes.

The same thing goes for heating.

As long as your insulation is on point, the TURBRO Greenland will heat up your apartment to comfy 75 degrees by the time you’re done with your morning routine.

All this can be achieved in spaces anywhere from 400 to 600 sq. ft.

However, I'm confident this portable air conditioner could handle even larger spaces, provided they're open-floor.

Now, like with SereneLife, I was delighted when I received the batteries for the remote.

I also received two foam seals in the box, which came in handy when I had to fill up the gaps between the window and the unit’s window kit.

One thing I must say is I was quite pleasantly surprised with the efficiency of this one, especially at this price point and for such a high BTU model. It still rates low for overall efficiency but its not terrible in any way.

This one draws 1380 kW per hour when running at max, making it objectively budget-friendly for an air conditioner this powerful.

Another thing that took me by surprise was the noise, or better yet, lack thereof.

I kept my TURBRO unit around 6 feet from where my head rests when I sleep, and it didn’t bother me in the slightest. If I had to guess, it was 50 dB at most.

I must say that I'm not a fan of the Auto mode.

This Auto mode switches between heating and cooling, depending on the room temperature, to keep it "where you want it," which I don't necessarily like.

TURBRO Greenland ‎GLP10AC-HU auto mode

Some of you might enjoy this, and it is supposed to be more "energy efficient."

Still, honestly, I'd rather it just shut off the compressor and keep the fan on to circulate air when the space gets "too cold" - so I just used other operating modes.

The only other thing that bothered me is that this one has no WiFi controls, while a cheaper, cooling-only black model has them.

Who is TURBRO Greenland ‎GLP10AC-HU best for?

What i Look For When Buying a Portable AC & Heater Combo

What is the Size of the Space That Needs Cooling or Heating?

The room size you're looking to cool down or heat up should be the starting point when shopping for the best portable air conditioners.

Choosing the "right" BTU rating ensures efficient heating and cooling capabilities without overburdening the unit or spiking your energy bills.[1]

In most cases, you'll want to start by figuring out the exact square footage.

Once you do, you can pick an appropriate portable air conditioner and heater combo based on the following data.

  • For <200 sq ft - Choose units with 5,000 to 8,000 BTUs.
  • For 200-400 sq ft - Choose units with 8,000 to 12,000 BTUs.
  • For 400-600 sq ft - Choose units with 12,000 to 14,000 BTUs.

However, these are just "rough" numbers, and even though they are pretty accurate in most climates and living conditions, ceiling height, insulation, and window size can affect the unit's performance.


What is the Cooling or Heating Capacity of Your Portable AC Unit?

As the mentioned above, a higher BTU means more cooling power and greater cooling area, and vice versa, so matching the two in either direction is more than fine.

However, portable air conditioner and heater combos don't carry the same BTU rating for cooling and heating.

For example, the Whynter ARC portable air conditioner has a 14,000 BTU cooling capacity and 13,000 BTU heating capacity.

You can see a similar difference with every other model I reviewed here or any other portable air conditioner out there.

It varies, but on average, you can see a 5-15% difference between the two.


Is the Unit Energy Efficient?

I wouldn't call energy efficiency a critical aspect when choosing a portable air conditioner heater combo, but still, it doesn't hurt to shop smart.

how much electricity does a portable AC use

In a nutshell, an energy-efficient unit reduces your carbon footprint and cuts down on electricity bills.

To find energy-efficient portable air conditioners, check for:

Energy Efficiency Ratio (EER): Unit's cooling capacity (in BTU) per hour relative to the power input (in watts).[2]
Seasonal Energy Efficiency Ratio (SEER): The unit's total cooling/heat output (in BTU) during the typical cooling/heating season divided by the total energy used.

A higher (S)EER indicates greater efficiency, but I wouldn't go overboard. Ideally, look for:

  • EER: 10-12
  • SEER: 14-15

Anything above that will provide excellent efficiency, but it's an overkill, which is why the top-rated energy-efficient product on my list is Whynter, with an EER of just above 11.

Useful Tip:

Unless you live in an area where you use your portable air conditioner and heater combo 8-12 hours per day, almost year-round, the cost difference isn't justifiable.


Does It Have Single or Dual Hose Drainage?

Choosing between single or dual hose systems in portable air conditioner heater combos is more than just a technical detail.

dual hose vs single hose portable AC

Objectively speaking, dual-house units are usually better, but I wouldn't call them necessary in most cases.

From my experience, single-hose units work perfectly in spaces smaller than 350 sq. ft. - like studio apartments.

On the other hand, if your goal is to quickly warm up or cool down the space, say, 500+ square feet - go with a dual-hose.

That said, here are the differences:

Single Hose Units

Single-hose models pull air from the room, cool it, and then expel the warm air outside through a single exhaust hose.

They're best suited for smaller spaces, as they are generally more compact and easier to install.

However, they can create negative pressure, drawing warm air into the room from other areas.

Dual Hose Units

One of the two hoses draws air from outside to cool the unit's compressor, and the other expels the warm exhaust air outside.

Dual-hose models are better for larger rooms or areas, as they are more efficient and faster in cooling/heating and do not create negative pressure.

Also, its filters last a bit longer. I also tell homeowners to think about these ACs like so, dual hose units are better at cooling, but are larger and have a higher initial cost. Single hose units are great for smaller rooms.


What is the Physical Size of The Unit?

The physical dimensions of portable models are crucial to ensure the unit fits comfortably in your space without obstructing movement or other functionalities.

Useful Tip:

Before you buy, check out the portable air conditioner’s footprint (width and depth) and height, particularly if you plan to place it in a confined area or near a window.

Also, check the unit's weight. Heavier models aren’t necessarily easily moved (especially if you try to move them with water in the drain tank), even if they have wheels.

Finally, I often see people forgetting about this, but you won't need your AC during some seasons, so consider where you'll store the unit when it's not in use.

A compact model like Vremi is easier to store in a closet or corner.


Can You Tolerate Some Level of Noise?

If you're like me and you often keep your portable air conditioner in the bedroom while sleeping, you have to think about the noise levels.

Unlike mini splits, whose compressors are in the outside unit, portable air conditioners keep everything in them, so naturally, they’re louder.

Many portable air conditioners create noise from 55 to 65 decibels (dB), but they could be both louder and quieter.

For context, 60 dB is comparable to a normal conversation, so you'll probably want to go lower than that, as noise could impact your life in more ways than one.[3]

The noise level can vary based on the unit's size, design, and operating mode, but in general, units with higher BTU ratings or faster fan speeds will produce more noise.

I often see that you can't entirely trust what the manufacturers say about their unit's dB levels.

For example, the Vremi unit I tested is supposedly only 52 dB, but I often found it clashing with my TV or conversation, especially later at night when things quiet down.

how to make portable AC quieter

Does the Unit Fit Your Budget?

Generally speaking, a portable air conditioner heater combo won't burn a hole in your wallet, as you can see from my picks.

Then again, if you go up by 2000 BTU, you could be looking at a 40% price increase, like with the BLACK+DECKER portable AC unit I reviewed.

Sure, higher-priced models may offer more features or efficiency, but I wouldn't always call these benefits worth the extra cost.

Energy-efficient models are significantly more expensive upfront, and while they do lower your energy bill, it's doubtful you'll ever break even.

Consider maintenance costs, too. A more expensive unit is usually more costly to maintain. I'm not just talking about filter replacements but repairs, too.

And yes, a warranty can save money on repairs and give you peace of mind for the time being, but I rarely encountered these portable air conditioner units breaking during the warranty period.

That said, I suggest you shop for mid-range units, like SereneLife SLACHT108.

Cheaper models are often low-quality and short-lived, and the high-end range isn't worth the extra cost, as it is with central air conditioning units.

ACLAB Note:

When budgeting, consider both the upfront as well as the running costs.


Additional Features To Look Out For?

I thoroughly enjoy a portable air conditioner with extra features for two reasons: they make me happy and make my life easier.

At this point, a remote control option is a must for a portable air conditioner. It allows you to adjust settings from your couch, which is where you’ll likely be when cooling down.

Also, I'd always look for a timer. It helps consume less energy and ensures the air conditioner unit runs only when needed.

I would also suggest looking for a dehumidifier (like SereneLife SLACHT108 offers) and an air filtration system, especially if you live in an open-plan apartment where the kitchen is part of your living space.

That way, you don't have to worry about smell or heavy, damp air.

Finally, for tech-savvy users, some more expensive units offer connectivity to smart home systems, giving you complete control via smartphone apps, Amazon Alexa, Google Assistant, or home pods, in which case you won't need a remote.

Portable ACs Vs Ductless Mini Splits – Which is the Right Choice?

While ductless mini splits are arguably better, longer-lasting, and more efficient, choosing between portable air conditioner and heater units and ductless mini splits entirely depends on your needs.

Portable air conditioners are ideal for temporary, flexible cooling solutions, especially in rented spaces.

They're less expensive upfront, easy to install, and you can take them with you in a second if you need to move.

However, ductless mini splits are more efficient, quieter, and offer better long-term savings on energy bills, so if you own a house or an apartment, the mini split would be the best air conditioner.

ACLAB Note:

Portable ACs offer the convenience of mobility. Mini-ductless, however, offer better efficiency and performance. 


FAQs

What Uses More Electricity, Heaters or Portable AC Units?

Space heaters usually use more electricity than portable air conditioner units. You can see this in combo units if you have the means to compare the energy consumption in both cool and heat modes.

Is Buying a Heater and Portable AC Separately More Expensive Than a Combo Unit?

Buying a heater and portable air conditioner separately is often more expensive than purchasing a quality air conditioner and heater unit. The standalone AC will be slightly cheaper but heaters vary and to get a similar output will be 50-75% on top of the combo units price.

Do I Need to Vent a Portable Air Conditioner Heater That is in Heat Mode?

You need to vent a portable air conditioner heater in heat mode. However, you may/should remove the intake hose from a double-hose unit during wintertime to avoid unnecessary water condensation in the drainage tank.

What Happens if You Don't Vent a Portable Air Conditioner?

If you don't vent a portable air conditioner, it will keep recirculating hot air back into the room, reducing its effectiveness to that of a mere fan.

So, Which is the Best Option For You?

In all honesty, all five of these best portable air conditioner and heater combo units could be the best AC unit for you.

While SereneLife SLACHT108 is my top pick as it best fits my space and is objectively a good choice, it makes sense to go with the Whynther or TURBRO unit if your condo is bigger than mine and you want to stay cool.

My #1 Recommendation
SereneLife SLACHT108 SLPAC

  • Fast and efficient cooling and heating
  • Very effective dehumidifier
  • More affordable than similar models
  • Two-way window kit
  • Has a safety breaker
