Quick Summary

Yes, you can run a window air conditioner indoors without having a window. There is no professional conversion kit available for purchase, but there are some reliable DIY options. Window air conditioners work by pulling in outside air, cooling it, and then pushing it back into the room. To effectively use an air conditioner indoors, you must make sure to seal off your area to prevent warm air from entering and cool air from leaving. Additionally, you must ensure your air conditioning unit is properly vented and has enough clearance from walls and furniture to avoid overheating. With careful planning, a window air conditioner can successfully be used indoors.

Guide to Running Window Air Conditioner Indoors: Can You Run A/C Inside?

Have you ever wondered if you can run a window air conditioner inside a room without a window? We have some good news: The answer is yes! While there is no easy, pre-made conversion kit available, there are indeed several DIY options to get the job done. Before considering a DIY setup, however, it’s important to understand the basics of how a window air conditioner works.

What is a Window Air Conditioner?

Window air conditioners are a great choice for cooling a single room within a home or a small apartment. Unlike a whole house system, a window unit does not require installation in a central unit and is easy enough for anyone to install in the window of a room. The window AC unit cools the space by circulating cooled air from a blower fan. The fan draws in the air from the indoor area and exhausts it outdoors, helping to keep temperatures cool inside.

Running a Window Air Conditioner Indoors

The key to running a window air conditioner without a window is to create a setup that is able to both draw in the room air and safely vent it outdoors. To do this, you will need to build a venting system. There are a few different things to consider when building your setup:

  • You will need an opening to draw in the cooler outdoor air.
  • You will need an exhaust vent so the hot air can be safely vented outside.
  • Ventilation is important; ensure the area where you place the window AC unit is not a closed-off space.
  • For larger spaces, you may need to purchase multiple window air conditioners.

DIY Venting Options

When it comes to venting, there are two main options for a DIY setup:

  1. Create a custom vent box – This is a great option for those who have some handyman skills, as it involves cutting and building your own vent box using Plexiglas and insulation.
  2. Install an air duct vent system – This option is a bit more complicated, as it involves routing the air in and out via nearby ducts.

Whether you choose to create a custom vent box or go with an air duct system, it’s important to ensure that everything is securely mounted and sealed for optimum performance. As always, if you don’t feel comfortable with this type of DIY project, it’s best to hire a professional to help you get the job done right.

Personal Experience

  Guide to Running Window Air Conditioner Indoors: Can You Run A/C Inside?

Having been an HVAC contractor for several years, I have a lot of personal experience installing and maintaining window air conditioners. Typically, these AC units are designed to be mounted in windows and draw in outside air to cool a room. But this isn’t always possible and some have asked if a window air conditioner can be used without a window. The answer is yes, you can. Although there are no commercially available conversion kits that can make a window air conditioner work without a window, some excellent DIY options are available.

If you would like to use your window air conditioner inside without a window, you first need to understand how these units work. Window air conditioners usually consist of an exterior unit and an interior one. The exterior one takes in outdoor air, cools it, and expels it into the room through the interior unit. To run the AC without a window, you can make a makeshift “window” for the exterior unit.

By cutting a suitable opening into an external wall and adding an appropriate exterior cover and seal, you can create a simulated window. Good insulation and weather-proofing is also important to prevent energy losses and rainwater from seeping inside. If done correctly, you can use the exterior unit for air intake and the interior one for air expel. That’s how you can use your window air conditioner without a traditional window.

Frequently Asked Questions

Does a window AC unit have to be outside?

Yes, a portable air conditioner should be vented outside in most cases for optimal results. Venting it outside allows the heat produced by the exhaust fan to be released, eliminating the possibility of it being drawn back in and wasting energy. It is strongly recommended that portable AC units are ventilated outdoors.

What happens if you run a window AC unit without a window?

If you run a window AC unit without a window, it won’t be able to operate properly and the warm air and water produced as byproducts of the cooling process will not be able to be expelled. This can cause damage to the unit and other parts of your home, so it’s important to ensure that your window AC unit is properly mounted in a window for it to work properly.

Why can’t you use a window AC inside?

Window AC units take heat from the indoors and pump it outdoors. If the entire AC unit is located inside the room, it will be pumping heat from one side to the other and dissipating more energy, leading to the room being even warmer. Therefore, a window AC unit cannot be used inside the room.

How much of a window AC needs to be outside?

When installing a window air conditioner unit, it needs at least 1 foot of clearance space on all sides for adequate ventilation. This includes the space between the sides of the unit and the alcove or adjacent wall (1.5 feet), and the sides of unit and any dense shrubs or solid fences (2 feet). For leafy plants, you should leave 6 to 8 inches of space. This ensures the unit will safely and properly function.

Do window AC units need a mounting bracket?

Yes, window AC units do need a mounting bracket in some cases. Very heavy units, those more than 100 pounds, require additional support, and in some locations, such as New York City, all window AC units need a mounting bracket regardless of their weight. As of Jun 29, 2021, mounting brackets are required for all window air conditioners in New York City.

What’s the best window air conditioner on the market?

The LG 8,000 BTU Window Air Conditioner is the best overall window air conditioner on the market. It is feature-packed, efficient, and effectively cools rooms of up to 340 square feet. It is also Energy Star rated and easy to install, making it a great choice for homeowners looking for an affordable, reliable air conditioning solution.

Are window mounted AC units safe?

The short answer to the question: “Are window mounted AC units safe?” is yes, but with greater caution. Window AC units have higher fire risk than central AC systems. However, with proper installation, operation, and maintenance, users can reduce the risk of fire and enjoy the cooling benefits of a window unit.

Do all AC window units have drain holes?

No, all AC window units do not have drain holes. Older style window AC units used to have drain holes or plugs used to remove the built-up water, but most modern window air conditioners do not. Instead, the water builds up and is distributed by a fan sling and thrown up against the condenser.

Can you put a window AC in a door?

No, you cannot put a window AC in a door. Window ACs require an outside wall and ventilation system to transfer heat outside, or the unit will simply heat the interior. Without an outside wall, this type of air conditioner will not function properly and will prove to be inefficient. Therefore, window ACs are not suitable for door installation.

Can you use a window AC without putting it in a window?

No, you cannot use a window AC unless you place it in a window. Window units are designed to be mounted in a window and expel warm air and water as byproducts of the cooling process, which cannot be redirected to any other location. Without mounting it in the window, the unit won’t work correctly.

Do window air conditioners have to be vented outside?

Yes, window air conditioners need to be vented outside in order to work optimally. A vent hose is used to redirect the hot air from the air conditioner out of the window, releasing the hot air outside. Not venting the air conditioner outside means that the hot air from the exhaust could enter back through the intake of the air conditioner, resulting in inefficiency and wasted money.

Can you run a window AC unit inside?

No, a window AC unit cannot be run inside. It is not designed for inside use, and installing it in an insulated tube to the outside may still not be effective. Additionally, prolonged exposure to the constant noise of a window AC unit can damage hearing.

How does a window air conditioner work?

A window air conditioner works by cooling and reducing humidity in a room. It uses an evaporator and fan inside to cool down the air and a compressor and condenser outside to release hot air. When used inside a room the machine releases both cold air and hot air which can challenge the desired temperature of the room.

What happens if you don’t set your window air conditioner in the window?

Without setting a window air conditioner in the window, the hot air from the air conditioner will be released inside the room. This causes the room to become even hotter. Consequently, setting a window air conditioner in the window is essential to ensure the air conditioner is effective and cooling your room.

What happens if you run AC inside a room?

Running an AC inside a room causes the existing air to be taken in and filtered by the AC, which then releases the air back into the room. Alternately, the AC can also pull air from outside the room, filter it, and then release it into the room. The hot air and cool air do not become separated during this process.

Final Thoughts

In conclusion, a window air conditioner can be used inside a room without a window if the user understands how to use the appliance correctly and safely. Although no professional conversion kit exists, there are several DIY options available that can create a secure and efficient setup. Individuals considering an air conditioning solution in a room without a window should research what option is best for their needs and skillset.
