How we chose portable air conditioners with heat

We compared cooling capacity, heating output, hose design, controls and installation needs. Models with a clear heating figure are easier to recommend for buyers who need more than occasional warmth.

The order reflects the whole package, so a lower-ranked model can still suit a specific room better. An inverter and dual hoses, for example, may matter more to a frequent cooling user than voice control.

Some capacity and coverage figures conflict, which we flag where they affect the choice. For room measurements and load factors, read what size air conditioner you need.

Which portable air conditioner with heat fits your room?

The larger Black+Decker is the strongest starting point for mixed heating and cooling needs. Choose among the others by your room's cooling load, available floor space and preferred controls.

Black+Decker 14,000 BTU smart portable air conditioner with heat: Best for connected living rooms

8.3/10Our score

• 14,000 BTU ASHRAE cooling
• 10,200 BTU SACC
• 10,000 BTU heating
• Wi-Fi, Alexa and Google Assistant

A Follow Me remote lets you place the temperature sensor near your seat, while app and voice controls make adjustments convenient. Choose it when both cooling capacity and a stated heating output matter.

See it on Amazon

Pros

• App and voice control
• Follow Me temperature sensing
• Window kit and drain hose included

Cons

• No inverter compressor
• Conflicting room coverage figures

Choose this Black+Decker for a living room where you want temperature control near the sofa and several ways to change settings. Its Follow Me remote acts as a thermostat, helping you base adjustments on the area you occupy.

Place that remote away from direct sun, a warm lamp or the outlet air stream. Those locations can distort the temperature it senses and lead to settings that feel wrong elsewhere in the room.

Cooling capacity is 14,000 BTU ASHRAE and 10,200 BTU SACC, with 10,000 BTU heating. Wi-Fi, Alexa and Google Assistant add convenient control when you're across the room.

Skip it if inverter operation is a priority or the room needs a smaller cooling unit. Black+Decker gives conflicting coverage figures, so match capacity to your room rather than choosing from the largest advertised area.

Black+Decker 12,000 BTU smart portable air conditioner with heat: Best for voice-controlled home offices

7.8/10Our score

• 12,000 BTU ASHRAE cooling
• 10,500 BTU heating
• Follow Me remote
• Wi-Fi, Alexa and Google Assistant

This model keeps the larger Black+Decker's control options while reducing cooling capacity. Its body is the same size, so choose it for the room's needs rather than a smaller footprint.

See it on Amazon

Pros

• App and voice control
• Follow Me temperature sensing
• Window kit included

Cons

• No inverter compressor
• Conflicting SACC and coverage figures

Choose the smaller Black+Decker for an office or bedroom that needs less cooling while keeping the same control options. It offers 12,000 BTU ASHRAE cooling and 10,500 BTU heating, so the smaller cooling number does not mean less heat.

The Follow Me remote can sit near your desk, and app or voice control lets you change settings without interrupting work. Keep the remote in a representative spot rather than beside a computer that releases warm air.

This model occupies the same floor space as the larger Black+Decker. Buying the lower-capacity version will not solve a tight placement problem, and the hose still needs room behind the cabinet.

Skip it if you need a smaller body or an inverter compressor. Its SACC and coverage figures conflict, so get the exact model's current capacity details from Black+Decker before deciding between these two sizes.

SereneLife 12,000 BTU portable air conditioner with heat: Best for remote-only households

7.4/10Our score

• 12,000 BTU ASHRAE cooling
• 7,000 BTU SACC
• 10,500 BTU heating
• Four operating modes

Remote and panel controls suit households that prefer adjusting comfort without an app. A timer, sleep mode and automatic swing cover common daily adjustments.

See it on Amazon

Pros

• Stated heating output
• Remote and 24-hour timer
• Removable washable filter

Cons

• No inverter compressor
• 70.3 lb weight

Choose the standard SereneLife if you prefer remote and panel controls and want a clear heat-output figure. Its 12,000 BTU ASHRAE cooling rating becomes 7,000 BTU under SACC, alongside 10,500 BTU heating.

That difference makes it a useful reminder to compare the same cooling measurement across models. SereneLife claims coverage up to 550 sq. ft., but a sunny room or open doorway can make that area harder to condition.

Automatic swing, 2 fan speeds, sleep mode and a 24-hour timer cover routine adjustments. SereneLife gives a noise range of 48–51 dBA; the sound still needs to suit how close you'll sit or sleep.

Skip this model if you'll regularly carry the unit upstairs. At 70.3 lb, it is better suited to rolling across a level floor and staying near a prepared window connection.

SereneLife 12,000 BTU inverter portable air conditioner with heat and dual hose: Best for long cooling sessions

7.2/10Our score

• 12,000 BTU ASHRAE cooling
• Inverter compressor
• Dual-hose system
• Wi-Fi control

Dual hoses and an inverter compressor make this a cooling-focused choice for a room used for long stretches. Check its heating output and cold-weather operating limits before relying on winter use.

See it on Amazon

Pros

• Dual-hose design
• Inverter compressor
• App and remote controls

Cons

• Heating output needs confirmation
• SACC needed for cooling comparison

Choose this SereneLife for long cooling sessions when you want dual hoses and inverter operation. The inverter can adjust compressor output as demand changes, while the two-hose arrangement separates the outdoor air paths used to shed heat.

Its 12,000 BTU ASHRAE cooling figure needs a SACC counterpart for a fair capacity comparison with the leading Black+Decker. App, remote and touch controls give you several ways to manage the room.

The package includes 2 hoses, connectors, a window plate and foam seals. Plan the window opening around both connections rather than assuming your old single-hose panel will work.

At 49 lb, it is lighter than the standard SereneLife above, though stairs still require care. Skip it as a winter-first choice until you confirm heating output and outdoor operating limits, since heat mode alone cannot tell you whether it will meet your needs.

5

SereneLife 14,000 BTU smart inverter portable air conditioner with heat: Best for open living spaces

7.1/10Our score

• 14,000 BTU cooling
• Inverter compressor
• Wi-Fi control
• SereneLife claims coverage up to 650 sq. ft.

Consider this inverter model for an open room where app control is useful. Its cooling coverage claim does not guarantee the area it can heat.

See it on Amazon

Pros

• Inverter compressor
• Wi-Fi and remote control
• Washable filter

Cons

• Heating output needs confirmation
• Cooling figures need clarification

Consider this SereneLife for an open living space where inverter operation and app control matter. SereneLife markets it with 14,000 BTU cooling and coverage up to 650 sq. ft., rather than as a solution for separate closed rooms.

Its model information also includes a 10,300 BTU description without a clear rating-method comparison. Clarify those cooling figures before choosing it over another unit based on capacity alone.

The cabinet weighs 47 lb and includes casters, a remote and a washable filter. SereneLife gives a 43–53 dBA operating range, so the quietest figure should not set your expectation for every setting.

Skip it if you need a fully defined winter heating plan before ordering. Its heating output needs confirmation, and the cooling coverage claim should not be reused as a heating-area figure.

6

SereneLife 8,000 BTU portable air conditioner with heat: Best for tight room layouts

7.0/10Our score

• 8,000 BTU ASHRAE cooling
• 5,000 BTU DOE cooling
• Four operating modes
• Window mount kit

The narrow body suits rooms where floor space limits your choices. Allow extra space for the hose, airflow and drainage rather than measuring only the cabinet.

See it on Amazon

Pros

• Narrow cabinet
• Remote and sleep mode
• Window kit included

Cons

• Heating output needs confirmation
• Single-duct design

Choose this compact SereneLife when a narrow cabinet is the deciding factor. Its 13 x 11 in footprint can be easier to place beside furniture, although airflow clearances and the hose increase the space it actually needs.

Cooling capacity is 8,000 BTU ASHRAE and 5,000 BTU DOE. That makes it the lower-capacity choice here, suited to evaluating for a smaller enclosed room rather than stretching across an open living area.

Remote control, 3 fan speeds, sleep mode and power failure memory make daily adjustments straightforward. A washable filter and included drain pipe also cover basic upkeep needs.

Skip it if you're trying to solve a large room's cooling problem with the smallest cabinet available. SereneLife's coverage figures vary between 300 and 350 sq. ft., and heating output needs confirmation before winter use drives the choice.

7

Whynter 14,000 BTU inverter portable air conditioner with heat: Best for humid living spaces

7.0/10Our score

• 14,000 BTU cooling
• Inverter compressor
• Dual hose-in-hose design
• Wi-Fi and voice control

A continuous-drain option and dehumidifier mode suit a room with a practical drain location. The larger cabinet makes it better suited to staying in one prepared spot.

See it on Amazon

Pros

• Inverter and dual hose-in-hose design
• App and voice control
• Upper gravity drain port

Cons

• Heating output needs confirmation
• Large cabinet and 77.3 lb weight

Choose the Whynter for a room where humidity control and a permanent drain location are part of the plan. Its dehumidifier removes up to 87 pints per day under suitable conditions, and an upper gravity drain port supports continuous drainage.

The inverter compressor and dual hose-in-hose design are useful reasons to shortlist it for frequent cooling. Whynter pairs 14,000 BTU cooling with a coverage claim up to 600 sq. ft., plus app and voice controls.

This is the largest cabinet here at 16.7 D x 19.5 W x 32.5 H in, weighing 77.3 lb. Measure the space around it, including access to filters, the drain and hose connections.

Skip it if easy carrying or a narrow floor space matters most. Also confirm heating output before choosing it for winter, and remember that a gravity drain needs a downhill route to a suitable outlet.

How do you size a portable AC for cooling and heating?

Size cooling and heating separately, using the room's conditions as well as its floor area. A cooling coverage claim is not a promise that the same unit can heat that area through winter.

Compare cooling capacity using the same method

Use SACC or DOE figures where available to compare portable cooling performance more meaningfully. ASHRAE numbers are generally higher, so comparing one unit's ASHRAE figure with another's SACC figure can point you toward the wrong size.

Measure length and width, then account for high ceilings, strong afternoon sun, poor insulation and connected spaces. A room with several warm windows can demand more cooling than a shaded room of the same area.

Avoid automatically buying the largest unit. Oversizing can lead to short cooling cycles and uneven comfort, while an undersized unit may run for long periods without reaching the set temperature.

Our portable AC sizing and hose guide explains how these measurements fit together. Close doors to spaces you do not intend to condition before judging how much room the unit must serve.

Check the portable air conditioner with heat for winter use

Check heating BTU, operating temperatures and drainage requirements before making a portable air conditioner with heat your main room heater. Cooling capacity and heating capacity are separate numbers.

If a model uses a heat pump, its ability to deliver heat depends partly on outdoor conditions. Other heating designs have different limits, so use the exact model's manual to establish how it works.

A stated heating output helps you compare models, but insulation and heat loss still determine room comfort. A drafty converted space needs a different plan from a well-insulated bedroom.

Keep reliable backup heat if the room must remain warm during freezing weather. Do not retire an existing heating source until you know the portable unit's operating range meets the local climate.

Does a portable air conditioner with heat need dual hoses?

Dual hoses are useful, but they are not required for every room. The main cooling benefit is reducing the indoor air a unit exhausts and the replacement air that can enter through gaps.

A single-hose unit uses room air to carry heat outdoors. As that air leaves, warmer air can enter through leaks, making window sealing and closing nearby doors especially useful.

A dual-hose unit separates intake and exhaust paths for the heat-rejection side. That arrangement can reduce pressure imbalance, but it still needs the correct panel, secure connections and clear outdoor openings.

Choose hose design alongside capacity and installation fit. Our dual-hose portable air conditioner guide explains the tradeoffs if this is your deciding feature.

How should you set up a heat-and-cool portable unit?

Set up the window connection, power supply and drainage before switching the unit on. A good location must support all three, rather than simply leave room for the cabinet.

Measure the window and floor space first

Check the window's opening direction, opening size and the kit's adjustment range. A sliding or double-hung window may accept a panel more easily than a hinged casement window, which can need a different sealing solution.

Mark the cabinet footprint on the floor, then add the manual's required clearances. Leave access to filters and drain ports, and avoid blocking the path past a bed or desk.

Renters should also check building rules before altering a window or fitting anything outside it. Our air conditioners for apartments guide helps compare options around those limits.

Keep the hose route short and clear

Use the hose within its permitted length and avoid sharp bends, crushed sections or unnecessary loops. Do not add an improvised extension unless the manufacturer approves it.

Seal gaps around the window panel so conditioned air stays indoors. Keep curtains clear of the unit's intake and outlet, and check that the outdoor vent opening remains unobstructed.

Follow the heat-mode instructions when the season changes. Do not assume that switching from cooling to heating means removing the hose or leaving the drainage arrangement unchanged.

Plan power and water together

Use a suitable wall outlet and follow the model's circuit requirements. Avoid power strips and extension cords, and keep the plug accessible rather than trapping it behind heavy furniture.

Position drainage so water cannot reach electrical connections. A gravity hose needs a steady downhill path without kinks, and its outlet must lead somewhere that can safely receive water.

Self-evaporation can reduce routine draining during some cooling conditions. It does not remove the need to follow the manual's tank, drain and mode-specific instructions.

Is a portable heat-and-cool unit suitable for a bedroom?

Yes, if the operating sound, airflow and window seal suit the room. The compressor sits indoors, so placement matters even when a unit offers sleep mode.

Noise figures are useful for screening options, but brands may measure them under different conditions. Fan speed, compressor activity and the distance from your pillow all affect what you hear.

Keep the cabinet level and away from loose furniture that could rattle. Direct airflow across the room rather than straight at your face, and avoid putting the unit where bedding can cover an intake.

An inverter may reduce repeated full-output starts as demand changes, but it does not guarantee silence. Sleep mode can also change temperature or fan behavior, so check what that setting actually does.

For a room where nighttime sound drives the choice, compare our best portable air conditioners for bedrooms. Use a timer around your routine rather than expecting the lowest possible thermostat setting to cool faster.

How do you care for a portable AC with heat?

Keep filters, airflow paths and drainage clear to support steady operation. A heat-and-cool unit used across seasons needs attention throughout the year, rather than only at summer startup.

Check the washable filter at the interval in the manual, sooner if dust or pet hair builds up. Switch the unit off, clean the filter as directed and let it dry fully before reinstalling it.

Inspect hose connections and window seals after moving the cabinet. A connection that has loosened behind the unit can spill warm exhaust indoors during cooling.

Check drains whenever you change modes, and respond to water-full alerts promptly. Never assume a drain arrangement that worked in cooling is automatically correct for heating or dehumidifying.

Before seasonal storage, drain and dry the unit according to its instructions. Keep the hose, adapters, panel pieces and remote together so next season's setup does not start with missing parts.

Which common buying mistakes should you avoid?

Avoid choosing by headline BTU, the smallest cabinet or the word “portable” alone. Each can hide a practical mismatch that becomes clear only after installation.

• Treating coverage as a heating figure: Check winter output separately, especially if the room will depend on the unit for warmth.
• Expecting whole-home comfort: Closed doors, corners and hallways restrict airflow even when the combined area appears to fit a coverage claim.
• Ignoring drainage: Decide where water will go before choosing the unit's position.
• Planning frequent stair moves: Casters help on level floors, but they do not make a heavy cabinet easy to carry.
• Buying for Wi-Fi first: Capacity, vent fit and power access determine whether the unit can do the job.
• Expecting dehumidifier mode to cool: Moisture removal is a separate task and may not provide the temperature control you need.

If the cabinet and hose would crowd the room, compare portable versus window air conditioners. A portable design makes sense only when its installation and floor-space needs suit your home.

Which portable air conditioner with heat should you choose?

Choose your portable air conditioner with heat by the room's hardest requirement. Start with capacity and winter suitability, then use hose design, controls and cabinet size to narrow the choice.

Pick the Black+Decker 14,000 BTU for a balanced mix of cooling capacity, connected controls and a clear heating figure. Choose the smaller Black+Decker when the cooling load is lower and you still want voice control.

Pick the standard SereneLife 12,000 BTU for remote operation and a stated heat output. Favor the SereneLife dual-hose inverter for frequent cooling, or consider its larger inverter sibling for an open room after clarifying capacity.

Choose the compact SereneLife when floor space is the main constraint. Pick the Whynter when its drainage options and humidity control suit a prepared location with room for the larger cabinet.

Before ordering, write down your window measurements, outlet location and drain route. If hose design still separates your finalists, use our dual-hose portable air conditioner guide to make that final choice.

Frequently asked questions

Do portable air conditioners with heat work as well as a furnace?

A portable air conditioner with heat is best planned around one room, while a central furnace distributes heat through a home; for regular winter heating, check heating output, permitted outdoor temperatures and drainage requirements. Keep reliable backup heat where freezing weather could exceed the portable unit's operating limits.

Do portable air conditioners with heat need a window hose?

Yes, these units need outdoor venting for cooling, and each includes a window kit; heat-mode venting and drainage depend on the model's design, so follow its manual rather than removing the hose by habit. Seal the window opening and keep the hose within the permitted length and bend limits.

How do I choose the right size portable air conditioner with heat?

Measure the room, compare cooling capacities using the same rating method, and check heating output separately; sunlight, ceiling height, insulation and open doorways change the load. Our air conditioner sizing guide explains the main fit factors, but cooling coverage alone should never decide your winter heating plan.

Can one portable unit cool and heat a whole home?

Plan on conditioning the room where the unit is installed, rather than several rooms behind closed doors; air needs a clear path to carry heating or cooling into another space. A large coverage claim does not guarantee even temperatures throughout a home, especially across hallways, floors or separate bedrooms.
