A room air conditioner has one job, but the wrong format can make summer more frustrating. Portable models need an exhaust hose and floor space, while window units need a compatible opening and a secure installation. Capacity matters too: an undersized unit may run constantly, while an oversized one can cool unevenly.
We compared ten of the best room air conditioners across portable and window-mounted designs, from compact bedroom units to smart models rated for large rooms. The BLACK+DECKER BPACT08WT is our top pick for its useful size, remote thermostat function, and straightforward three-in-one design. The rest of the list covers quieter large-room options, efficient window units, and connected models.

1. BLACK+DECKER BPACT08WT: Best Overall
Pros
- Cooling, fan, and dehumidifier functions in one unit
- Follow Me remote can measure temperature from across the room
- Casters and side handles make repositioning manageable
- Includes a window installation kit
Cons
- Not designed for the largest rooms on this list
- Portable units take up floor space and require hose installation
- The listed dimensions vary across the product information
Best for: someone who wants a practical portable unit for a bedroom or medium-size room.
The BLACK+DECKER BPACT08WT gets the fundamentals right without turning a small room into an appliance showroom. It is a portable unit with cooling, fan, and dehumidifier modes, so it can handle a hot afternoon, a less humid evening, or simple air circulation without needing a separate machine. The casters and side handles are useful when you want to move it between rooms, although its 52.9-pound weight means “portable” still involves some effort.
Its stated cooling capacity is 9, 000 BTU, with a 5, 300 BTU SACC rating, and the manufacturer lists coverage up to 400 square feet. That makes it a sensible match for a bedroom, home office, or medium living area rather than a wide open floor plan. The included window kit provides the exhaust connection needed for portable operation, and the top-mounted controls include an LED display for quick adjustments.
The Follow Me remote is the feature that separates this model from several basic portable air conditioners. Instead of relying only on the temperature near the main chassis, the remote can act as a thermostat, which gives the unit a better chance of responding to the conditions where you are sitting or sleeping. That is a small detail, but it addresses one of the most common annoyances with floor-standing AC units.
The Midea 8, 500 BTU Portable AC is a better fit for a genuinely small room, while the BLACK+DECKER BPACT14WT is the more suitable step up for a large space and connected controls. The weakness here is capacity. Its stated 400-square-foot coverage will not make it the right pick for a large open living room, and the exhaust hose still requires a window arrangement that can accept the kit. Choose this one when you want a balanced, conventional portable AC for a moderate room.
2. TECXERLLON 15, 000 BTU: Best for Large Rooms
Pros
- Rated for spaces from 500 to 800 square feet
- Four operating functions include sleep mode
- Claims operation as low as 48 dB
- Self-evaporating system can reduce manual draining
- Child lock and a three-year compressor warranty
Cons
- Weighs 70.4 pounds
- Large chassis may be difficult to move over thresholds
- The broad coverage claim depends on the room and heat load
Best for: cooling a large bedroom, living room, or home office where quiet operation matters.
The TECXERLLON 15, 000 BTU is built around the problem smaller portable units cannot solve well: cooling a room that has a lot of air to move. It is rated for rooms from 500 to 800 square feet, and its high-efficiency rotary compressor is intended to bring down the temperature quickly. That makes it a more natural choice for a large bedroom or living room than the smaller BLACK+DECKER model above.
The four-in-one layout includes cooling, dehumidifying, fan, and sleep functions. The dehumidifier is rated to remove up to 100 pints of moisture per day, a figure that is most relevant in muggy conditions where the room feels uncomfortable even after the temperature drops. A 35-degree to 80-degree auto-swing range helps spread air across a larger room rather than concentrating it directly in front of the machine.
Noise is one of the more interesting claims here. The unit is listed at as low as 48 dB, and sleep mode changes airflow and compressor activity as the room cools. That does not make a compressor disappear, but it gives this model a stronger bedroom case than a large unit with no nighttime setting. The remote works from up to 23 feet away, while the LED touch panel handles direct control.
The included window kit is designed for most sliding windows, and 360-degree casters help with repositioning. Still, 70.4 pounds is substantial, so this is not the model to buy if you expect to carry it up stairs often. The QZMDSM 16, 000 BTU Smart AC offers Wi-Fi and a lower claimed 45 dB sleep-mode figure, while the TECXERLLON counters with clearer drainage details, a child lock, and a stated compressor warranty. Pick this model for large-room cooling with simpler controls and less dependence on an app.
3. QZMDSM 16, 000 BTU Smart AC: Best Smart Controls
Pros
- Six operating modes cover cooling, fan, dehumidifier, auto, sleep, and energy saving
- Wi-Fi app, remote, and LED touch controls
- Claimed 45 dB operation in quiet mode
- Child lock and 24-hour timer
- Wheels and side handles support room-to-room use
Cons
- Tall 36.1-inch body may be awkward under some windows
- No specific dehumidification capacity is listed
- Smart controls add setup steps compared with a standard remote
Best for: households that want to schedule and control a large portable AC from a phone.
The QZMDSM 16, 000 BTU Smart AC is the most feature-heavy portable model in this group. Its appeal is not only the cooling capacity, but the number of ways to manage it. You can use the Wi-Fi app, included remote, or LED touch panel, and six modes cover cooling, fan, dehumidifier, auto, sleep, and energy saving. That gives it a useful role in a home office or bedroom where schedules matter.
The product is rated for rooms up to 750 square feet. Its 16, 000 BTU capacity is the highest listed among the portable models here, although room layout, sunlight, insulation, and ceiling height will affect the result. At 42 pounds, it is also notably lighter than the TECXERLLON, despite having a taller chassis. The dimensions are 36.1 inches high, 14.2 inches long, and 15.9 inches wide, so check the area around your window before committing to the installation.
The claimed 45 dB quiet operation is intended for sleep use, and the 24-hour timer can keep the unit from running longer than needed. A child lock is another practical touch for family rooms. The window kit is designed for tool-free installation, while 360-degree wheels and side handles make moving it between rooms easier once the hose is disconnected.
The BLACK+DECKER BPACT14WT has a more established control approach with Wi-Fi, Alexa, Google Assistant, and a Follow Me remote, but it offers three primary functions rather than six. The QZMDSM wins on operating modes and quiet-mode claims, yet its tall design and app setup make it less simple than the TECXERLLON 15, 000 BTU. Skip it if you want a basic plug-in-and-use machine. It is the better match for a connected home where remote scheduling is part of the daily routine.
4. BLACK+DECKER BPACT14WT: Best Established Brand
Pros
- 14, 000 BTU ASHRAE capacity with a 10, 200 BTU SACC rating
- Wi-Fi app and voice control through Alexa or Google Assistant
- Follow Me remote adds remote thermostat control
- Cooling, fan, and dehumidifier modes
- Includes a window installation kit
Cons
- Weighs 68.3 pounds
- More cumbersome than smaller portable units
- Three-in-one design lacks the broader mode selection of some rivals
Best for: large-room cooling from a familiar brand with app and voice controls.
The BLACK+DECKER BPACT14WT is the straightforward upgrade from the brand’s smaller portable unit. It is rated at 14, 000 BTU ASHRAE and 10, 200 BTU SACC, with stated coverage up to 700 square feet. That combination places it in the same broad class as the large-room models here, but its controls are especially appealing if you already use Alexa or Google Assistant.
This is a three-in-one machine, with cooling, fan, and dehumidifier modes. Its top-mounted panel includes an LED display, and the full-function remote includes the Follow Me feature. Having the remote act as a thermostat can help when the air near the unit is cooler or warmer than the rest of the room. It is a more targeted convenience than simply adding another control method.
The smart functions let you connect through an app and use voice commands, while the included window kit handles the exhaust installation. The listed dimensions are 16.5 inches by 14.06 inches by 27.09 inches, and the product weighs 68.3 pounds. Casters are not specifically listed in the supplied features, so expect this to be a machine you position carefully rather than casually move every day.
Compared with the QZMDSM 16, 000 BTU Smart AC, this BLACK+DECKER gives up the extra operating modes and lower claimed sleep-mode noise, but it offers a more familiar control ecosystem and a useful Follow Me remote. The TECXERLLON 15, 000 BTU has more detailed humidity and drainage claims. This model is not the one for shoppers who want the lightest unit or the quietest specification. It is a strong fit for a large room when brand familiarity and voice control matter more than a long list of modes.
5. Frigidaire 5, 000 BTU Window AC: Best for Small Rooms
Pros
- Compact window-mounted design for rooms up to 150 square feet
- Two fan speeds and adjustable temperature control
- Listed 52 dBA operation
- Auto restart restores previous settings after an outage
- Washable filter and long three-prong power cord
Cons
- Not suitable for medium or large rooms
- No remote or Wi-Fi control is listed
- Window installation is less flexible than a portable design
Best for: a small bedroom, dorm room, or home office with a compatible window.
The Frigidaire 5, 000 BTU Window AC is refreshingly focused. It is made for spaces up to 150 square feet, so it does not pretend to cool an entire apartment. In a small bedroom or office, that narrower target is an advantage because the unit can be selected around the actual room rather than oversized for a space it cannot efficiently serve.
Two fan speeds and Effortless Temperature Control keep operation simple. The listed sound level is 52 dBA, which is not silent but is reasonable for a small window unit. Auto restart remembers the previous settings after power returns, a useful feature in areas where brief outages are common. There is no supplied information about Wi-Fi or a remote, so this is a physical-control appliance rather than a smart-home product.
Maintenance is also uncomplicated. The washable filter can be removed and cleaned, helping keep dust and pet hair from building up in the air path. Adjustable side panels help the unit fit the window, and the extra-long three-prong cord is intended to avoid the need for an extension cord. Those details matter more than a long feature list when the goal is dependable cooling in one small room.
The GE 6, 000 BTU Window AC covers up to 250 square feet and adds a remote, digital thermostat, timer, and energy-saver mode. That makes GE the more versatile choice for a larger small room. The Frigidaire remains the better fit when 150 square feet is the honest target and you prefer a less complicated window unit. Do not choose it for a living room, open-plan space, or any room that regularly receives heavy afternoon sun unless the sizing is carefully checked.
6. KoolSiln 14, 000 BTU AC: Best Drainage-Free Design
Pros
- Rated for rooms up to 700 square feet
- Wi-Fi, voice commands, and remote control
- Sleep mode reduces fan noise and dims the display
- Auto-evaporation system is designed to reduce draining
- Includes a window kit for vertical and horizontal sliding windows
Cons
- Weighs 66.6 pounds
- The supplied feature claims are broad and should be read carefully
- Large portable units still require floor space and an exhaust hose
Best for: large-room cooling where minimizing routine water drainage is a priority.
The KoolSiln 14, 000 BTU AC puts drainage near the center of its design. Its 360-degree auto-evaporation system is claimed to convert 80 percent of excess water into cool air, with up to 72 hours of drainage-free cooling under the stated conditions. That is the kind of feature that can make a portable unit less demanding in a humid room, though very humid conditions can still require use of the drain system.
The unit is rated for spaces up to 700 square feet and uses a 77-degree air outlet to distribute airflow. It also lists a temperature range from 61 to 90 degrees, cooling, fan, and dehumidifier modes, and an 8-hour sleep timer. The product information identifies a 14, 000 BTU size, but does not provide a separate SACC figure, so comparisons with units that list both ratings should be made cautiously.
Smart control is well covered. The app can manage temperature, fan speed, modes, and schedules, while voice commands and the included remote offer alternatives. Sleep mode dims the display and reduces fan noise, with operation claimed as low as 48 dB. Installation is designed around three steps and window openings from 20.39 to 67 inches, with the product stating compatibility with most vertical and horizontal sliding windows.
The BLACK+DECKER BPACT14WT offers a stronger named-brand option with a Follow Me remote, while the VACOOR 14, 000 BTU AC emphasizes upward airflow and reports a 235 CFM airflow figure. KoolSiln’s advantage is its focus on moisture handling and control flexibility. Its disadvantage is the same physical burden common to this category: 66.6 pounds and a substantial footprint. It suits a large room that needs extended cooling with fewer interruptions for drainage.
7. GE 6, 000 BTU Window AC: Best Electronic Window Unit
Pros
- Digital thermostat with remote control
- Energy Saver mode and a 24-hour timer
- Auto restart after a power outage
- Washable filter with a reminder indicator
- Covers rooms up to 250 square feet
Cons
- Not Wi-Fi compatible
- Fixed-chassis installation requires a suitable double-hung window
- Louder on high than on low
Best for: small rooms that need digital control and scheduling without a portable exhaust hose.
The GE 6, 000 BTU Window AC is a good middle ground between the basic Frigidaire and the much larger units in this roundup. Its stated coverage reaches 250 square feet, which suits a bedroom, home office, dorm room, or small apartment area. Because it sits in the window, it preserves floor space and avoids the exhaust hose that comes with portable air conditioners.
Electronic controls make this more convenient than a mechanical dial unit. The thermostat can be set from 64 to 86 degrees, and the remote lets you change settings across the room. Energy Saver mode cycles the compressor to maintain the target temperature rather than running continuously, while the 24-hour timer supports scheduled operation. Auto restart returns the unit to its previous settings after an outage.
The supplied noise figures are 52 dBA on low and 56 dBA on high. That makes low-speed operation the better choice for sleeping, while high speed is available when the room needs faster circulation. The washable filter has a reminder indicator, a useful prompt for maintenance rather than a feature that disappears after installation.
The window requirements are more specific than the portable models. This fixed-chassis unit is designed for double-hung windows from 27.125 to 36 inches wide and at least 13.375 inches high, and it includes an EZ Mount kit with expandable side panels. The Frigidaire 5, 000 BTU Window AC is better for a smaller 150-square-foot room, while the Midea 12, 000 BTU U-Shaped AC is the superior quiet large-room option. Choose GE when digital control and a timer matter, but Wi-Fi does not.
8. Midea 8, 500 BTU Portable AC: Best Compact Smart Portable
Pros
- Smart app control with Alexa and Google Assistant support
- Cooling, dehumidification, and fan-only modes
- Covers spaces up to 150 square feet
- Includes a remote and 24-hour timer
- Washable, reusable filter
Cons
- Coverage is limited to small rooms
- Portable design still needs a window hose
- Filter cleaning is recommended weekly during operation
Best for: a small room where portable placement and smart scheduling are more useful than window installation.
The Midea 8, 500 BTU Portable AC is aimed at the same small-room territory as the Frigidaire, but it takes a different route. Its 8, 500 BTU ASHRAE rating and 5, 000 BTU SACC rating are paired with stated coverage up to 150 square feet. Instead of occupying a window, it rolls across the floor and vents through the included hose and adjustable brackets.
There are three operating modes: cooling, dehumidification, and fan only. The temperature range runs from 62 to 90 degrees, and the 24-hour timer gives it a useful schedule for a bedroom or office. The compact remote handles everyday adjustments, while the SmartHome app can change modes and set schedules from a phone. Alexa and Google Assistant support adds voice control for compatible homes.
The dimensions are 27.76 inches high, 11.54 inches long, and 11.61 inches wide, with a listed weight of 47.18 pounds. That is not featherlight, but the narrow footprint should be easier to place than the large-room machines. The supplied window kit fits openings from 26.5 to 48 inches, so window compatibility still needs checking before purchase.
The Frigidaire 5, 000 BTU Window AC is quieter on paper at 52 dBA and avoids floor space, but it cannot move between rooms without reinstalling. The BLACK+DECKER BPACT08WT covers more space and adds the Follow Me remote, while the Midea brings more connected control to a small-room format. Its main limitation is capacity, and the manufacturer recommends cleaning the filter every week of operation. If you are choosing among portable units for a genuinely small room, this is one of the more flexible options here.
9. VACOOR 14, 000 BTU AC: Best Upward Airflow
Pros
- Upward full-width vent is designed to spread air through the room
- Lists 235 CFM airflow
- Cooling, fan, and dehumidifier modes
- Sleep mode and remote control
- Water-full alert and washable filter
Cons
- Weighs 70.55 pounds
- No Wi-Fi control is listed
- The broad 700-square-foot claim depends heavily on room conditions
Best for: large rooms where air direction and circulation are more important than app control.
The VACOOR 14, 000 BTU AC takes a different approach to portable cooling by directing air upward through a full-width vent. The product lists 235 CFM airflow and says the design is intended to circulate cool air more effectively than a conventional front-vent arrangement. In a living room or apartment, that upward direction may help prevent the coldest air from pooling directly in front of the chassis.
It is rated for large rooms up to 700 square feet, with a temperature range from 61 to 90 degrees. The machine has cooling, fan, and dehumidifier modes, and the dehumidification function is listed at up to 50 liters per day. That figure speaks to humid conditions, where reducing moisture can make a room feel more comfortable even before the thermostat changes significantly.
Sleep mode is designed to reduce operating noise to as low as 50 dB. The remote is specified for a range of 20 to 26 feet, and the airflow angle can be adjusted from 45 to 90 degrees. Those controls make the vent design more useful because you can aim the air toward the center of the room or upward away from the bed.
The installation kit is intended for horizontal and vertical sliding windows, and the unit includes wheels, side handles, a drain hose, a water-full alert, and a washable filter. At 70.55 pounds, it is one of the heavier products here. The KoolSiln 14, 000 BTU AC is the better alternative if app and voice control are essential, while the TECXERLLON 15, 000 BTU claims quieter operation and covers up to 800 square feet. Choose VACOOR for its airflow layout and simple remote-driven operation, not for smart-home integration.
10. Midea 12, 000 BTU U-Shaped AC: Best Quiet Window Unit
Pros
- U-shaped design separates much of the compressor noise from the room
- Listed operation as low as 32 dBA
- Inverter system and 15.0 CEER rating
- Wi-Fi and voice control
- Window can open when the unit is installed
Cons
- Requires a sturdy, compatible window installation
- Heavier than smaller window units
- The U-shaped bracket needs careful installation
Best for: quiet cooling in a larger room when a window-mounted design is practical.
The Midea 12, 000 BTU U-Shaped AC is the standout choice for anyone who dislikes the sound of a conventional window compressor. Its U-shaped design places part of the unit outside the window, using the opening to separate indoor and outdoor noise. Midea lists operation as low as 32 dBA, which is substantially quieter on paper than the 52 dBA low setting specified for the GE.
Its 12, 000 BTU capacity is intended for rooms up to 550 square feet. The inverter system adjusts its output instead of relying only on repeated full-power cycles, and the listed energy efficiency rating is 15.0 CEER. That combination is aimed at steady cooling rather than abrupt swings. The product also states that it was the first window AC of its kind to obtain ENERGY STAR certification.
Smart control is included through the Midea SmartHome app, with Alexa and Google Assistant support. The flexible window design can leave the window partially open for fresh air and preserve more of the view than a conventional box-style window unit. When the window is closed, an anti-theft mechanism locks it in place.
Installation requires the supplied quick-snap bracket, sidearms, and a single-hung or double-hung window from 22 to 36 inches wide with a minimum height of 13.75 inches. That is more involved than rolling a portable unit into position, and the 56.88-pound weight means the bracket must be installed carefully. The GE 6, 000 BTU Window AC is easier to match to a smaller room, while portable models are better when the window cannot support a permanent unit. If quiet operation is your first concern and the window fits, Midea is the strongest choice here.
How to choose best room air conditioners
Start with the room, the window, and the installation format. A powerful machine cannot compensate for a poor fit, a blocked exhaust hose, or a window that cannot safely support the unit.
Cooling capacity and room size
BTU indicates cooling capacity, but the coverage figure gives a more useful first filter. The list ranges from the Frigidaire’s 5, 000 BTU rating for spaces up to 150 square feet to large portable units rated for 700 or 800 square feet.
Treat coverage as a starting point rather than a guarantee. Direct sun, high ceilings, poor insulation, cooking heat, and an open floor plan all increase the cooling load. For a small enclosed bedroom, a compact unit may be enough. A large living area needs more capacity and better air circulation.
Portable or window-mounted design
Portable air conditioners sit inside the room and vent warm air through a window kit. They are useful for renters, rooms without a suitable permanent installation, and households that need to move cooling between spaces. The trade-off is floor space, hose management, and the need to roll a heavy machine into position.
Window units leave more floor area available and usually keep the compressor outside the room. They require a compatible window and a secure installation, but they can be the cleaner choice for a room that needs cooling every day. For a deeper look at the installation and sizing trade-off, the differences between floor-standing and window cooling can help clarify the choice.
Noise and sleep operation
Noise figures are useful when comparing models, but they describe a particular operating condition rather than every sound you will hear. Portable units have compressors and fans inside the room, while window units can place more of the mechanical noise outside.
Look for a sleep mode, a low fan setting, and a timer if the unit will run overnight. The Midea U-shaped model lists operation as low as 32 dBA, while the QZMDSM lists 45 dB in quiet mode and the Frigidaire lists 52 dBA. Those numbers are not perfectly interchangeable, but they show the broad difference between designs.
For a bedroom, a smaller correctly sized unit running quietly is often more comfortable than a powerful machine that cycles loudly beside the bed.
Controls and scheduling
A remote is useful when the unit is across the room, but smart controls add scheduling and away-from-home adjustments. The GE includes a remote, digital thermostat, energy-saver mode, and 24-hour timer. Midea, BLACK+DECKER, KoolSiln, and QZMDSM models add app control, with some also supporting Alexa or Google Assistant.
Do not choose Wi-Fi merely because it is available. App setup is another step, and a reliable physical panel still matters when the network is unavailable. A Follow Me remote can be more useful than voice commands if the unit is cooling a bedroom or home office.
Moisture handling and maintenance
Cooling pulls moisture from the air, and portable units need some way to manage that water. Self-evaporating systems can reduce manual draining, but humid conditions may still require a hose or tank maintenance. The TECXERLLON and KoolSiln models make especially strong drainage-free claims, while the VACOOR includes a water-full alert and drain hose.
Filters need regular attention. Washable filters appear on the BLACK+DECKER, Frigidaire, GE, Midea, and VACOOR models in this list. A filter that is easy to remove and clean is more likely to be maintained, which helps airflow and cooling performance over time. If dust reduction is also a priority, how cooling and air cleaning serve different jobs is useful context.
Frequently asked questions
What size air conditioner do I need for a bedroom?
Match the unit to the room’s square footage first, then account for sunlight, insulation, ceiling height, and heat from electronics. The Frigidaire 5, 000 BTU model is listed for up to 150 square feet, while the Midea 8, 500 BTU portable model has the same stated coverage but adds floor placement and smart controls. Larger spaces need a model with a higher capacity and broader airflow.
Are portable air conditioners better than window units?
Neither format is universally better. Portable models are easier to use in rental homes and can move between rooms, but they occupy floor space and need an exhaust hose. Window units preserve floor area and can be quieter indoors, though they require a compatible window and a secure installation.
Can a portable air conditioner cool a large living room?
Several models here are listed for large rooms, including the TECXERLLON 15, 000 BTU, QZMDSM 16, 000 BTU, and multiple 14, 000 BTU units. Actual results depend on room layout, sunlight, insulation, and whether the space is open to other rooms. Measure the area and pay attention to the manufacturer’s coverage claim before choosing.
Do portable air conditioners need to be drained?
Some portable units evaporate much of the collected moisture through the exhaust system, reducing how often they need manual draining. High humidity can still produce more water than the system can evaporate. Models with a drain hose, water-full alert, or specific drainage guidance are easier to manage in muggy climates.
Is a higher BTU rating always better?
No. A higher capacity can cool a larger space, but an oversized unit may cool the air quickly without distributing comfort evenly. It also may not be the right physical fit for the room or window. Select capacity based on room size and conditions rather than choosing the largest number available.
Are window air conditioners quieter than portable models?
They often can be, because a window unit places more of its compressor outside the room. The Midea 12, 000 BTU U-shaped model specifically lists operation as low as 32 dBA, while portable units in this roundup list quiet-mode figures from 45 to 50 dB. Actual sound depends on the fan setting, compressor cycling, and installation.
How often should I clean an air conditioner filter?
Follow the product’s instructions, but inspect the filter regularly during the cooling season. The Midea 8, 500 BTU portable model recommends weekly cleaning during operation, and washable filters are included with several models here. A clogged filter can restrict airflow and make the unit work harder.
The bottom line
The BLACK+DECKER BPACT08WT is our leading pick among the best room air conditioners because it covers a useful range of rooms without chasing every possible feature. Its three-in-one operation, Follow Me remote, casters, and included window kit make it a practical choice for bedrooms and medium-size spaces. For large rooms, the TECXERLLON 15, 000 BTU is the stronger recommendation, with higher capacity, sleep mode, wide-angle airflow, and detailed moisture-management features.
Choose the Midea 12, 000 BTU U-Shaped AC instead when quiet window-mounted cooling is more important than portability. Small-room shoppers should look first at the Frigidaire 5, 000 BTU Window AC or GE 6, 000 BTU Window AC, depending on whether simple operation or digital scheduling matters more.
If you are undecided, measure the room and window first, then choose the quietest correctly sized unit that fits the installation you can actually use.
