While summers are just around the corner, you better be prepared for it ahead of time. By preparation, we don’t mean cool clothes, sunblock’s and all (well, that is important obviously) but we here mean you should get a window air conditioner to keep you cool in that hot and warm weather. A window air conditioner relaxes and cools you off and can help you control or manage energy costs. This very guide will assist you to learn a little about window air conditioners and also how to choose the best window air conditioner for 1000 sq. ft, for your home, office, mighty kitchen and halls. If, you are looking for window air conditioners for bedroom check this list.

A window air conditioner, which is also known as a window AC or a room air conditioner, is manufactured to cool a room and can be a decent, good, and an easy-to-install option if a central air conditioning system is not so practical or if you prefer to cool a single room rather than cooling the whole house. Using the quietest window air conditioner can boost the quality of your life. People approximately spend a third of their life at their homes, sleeping. So, what’s the point of spending that time in discomfort? If you do not use an air conditioner during the warm season, you cannot sleep well. And if you use a loud air conditioner, you cannot sleep at all. The best window AC unit is the one which can cool down your room without being so loud.

What is the best way to beat the heat of Summers?

Indoor air conditioning is probably one of the best ways to beat that summer heat. For many people, the convenience of the central air remains out of reach or they don’t want to have it, which leaves the window Air Conditioner window unit as the next big thing. Today’s window models are way better than what you might be used to previously, and not like the massive energy hogs they once were. The modern AC window units provide relief from the searing temperatures, use less electricity than ever before and removes humidity.


Relying upon the model, a window air conditioner can operate in various modes. The ‘cooling mode’ takes in the room air, cools it and then directs it back into the room. Some models permits you to select from various preset cooling levels; the air conditioner cools at the selected level unless you change the setting or turn it off. Other models let you set the desired temperature for the unit to maintain. The air conditioner operates unless it senses that the air is at the desired or required temperature and then cycles off, cycling back on when the temperature rises above that specified setting. A ‘fan-only mode’ uses relatively less energy as it does not provide cooling. The appliance then simply circulates and filters the room air. Some of the window air conditioners also have a ‘heating mode’. As with the cooling function, you simply set the desired temperature and the heating system cycles on and off to properly maintain it.


1.Measure your windows

Normally, window-mounted air conditioners units are exactly that. The body of the unit sits partially inside and partially outside of your room’s window pane. A bracket or a brace of some sort holds the air conditioner in its place. This bracket also divides the inside from the outside, and the hot air from the cool air. Since there is no particular universal standard for the window size, measuring your window dimensions is obligatory. Once you have that information, you can then easily compare it against the specifications of any potential new unit. This way you will hopefully avoid any nasty surprises when it is time to install.

2.Permanent or temporary use

First off, you need to consider if you need the window air conditioner for permanent use or temporary use. Determine if you plan to remove your air conditioner at the end of summers or leave it in the window whole year round. There are tradeoffs to both approaches. With the permanent setup, you do not have to reinstall your air conditioner every year. Even if your permanent air conditioner mount is well insulated, though, it obviously won’t be as draft free as the quality window which is completely shut. This can be a little problem if you live in a place with near or below freezing temperatures in winters. But if you live somewhere with the mild winters, you should probably be just fine.

The portable air conditioner represents the third option. These free standing units cost more than their window-style cousins, but these move easily from the room to room as they come with wheels. You just need to mount an exhaust hose assembly inside the window, but the hose hardware is light weight and it installs much more easily than the whole in-window AC unit.

3.Think about condensation

One downside to the air conditioned comfort is the condensation. Similar to the dehumidifiers, Air Conditioner units pull moisture from air as they run. That collected water needs to go somewhere, normally pooling in an internal drip tray. Some Air Conditioner models advises you to drill the small hole in them for easy drainage. You can then also hook a drain hose there, to channel an excess water toward wherever you want the water to go.

4.Electricity and power

Decades ago, it was definitely not uncommon for the old air conditioners to need high-voltage (240V) of electrical outlets. The current models are a lot more efficient and better. They can operate at the 120 voltage, the default voltage for the US home appliances. It’s a nice idea to check the situation in your individual home. A legacy, defunct Air Conditioner unit may only have a 240V outlet nearby. Here is another problem you might possibly run into. The closest outlet is 120 voltage, but it shares a circuit with the other power-hungry electronics or appliances. In either case, you may have to have an electrician make some repairs or add extra circuits.

5.Sweat the small stuff

The features beyond the size and the cooling power might seem minor, but they can actually have a meaningful impact on how you use a window Air Conditioner unit. Many Air Conditioners units can make unholy racket when they are running, so make sure to check the noise rating of whatever models you are considering. Decent and innovative features have started to appear on some of the window air conditioners.


If purchasing a new or first window air conditioner seems easier to you, trust us, it’s not. It’s not that hard either, but if you don’t do your homework, it is very easy to end up with the wrong machine. You might get stuck with something too small, too big, or which simply does not fit where you want it to. Read on to learn how to avoid the risks. Deciding on a window air conditioner depends on few key factors. Here is a list of the details you should figure out before you pick.

  • Target coverage area in square feet (which is 1000 square feet in this very article).
  • Shape and size of your windows.
  • Where to channel the water from the condensation.
  • Position and voltage of the nearby electrical outlets.

We compiled some of the best window air conditioner for 1000 square feet and mentioned each one’s pros and cons along with their description. So, let’s get into the window AC’s.

Window air conditioners normally have a cooling capacity ranging from 5,000 to 12,500 British thermal units (Btu/hr.). According to the rule of thumb, an air conditioner needs 20 Btu for every square foot of living space. But don’t only buy by Btu. Other several considerations, such as the size of your windows and doorways, and the ceiling height, might require more cooling power.

To measure your room efficiently, just multiply the length of the room by its width. Add together the size of rooms that are not separated by doors as the air conditioner will need to cool both of the spaces. It’s recommended to adjust for the following circumstances:

  • If room is heavily shaded, reduce the capacity by 10 percent.
  • If room is very sunny, increase the capacity by 10 percent.
  • If more than two people occupy the room regularly, add 600 Btu for every additional person.
  • If unit is used in a kitchen, increase the capacity by 4,000 Btu.

Window air conditioners are manufactured to cool one or multiple rooms which don’t have access to the adequate cooling.  There are a lot of things to consider when shopping for a window air conditioner, like maintenance and size.


Here we are listing few things you should consider when you are shopping for a window air conditioner.

  • Cooling Capacity/Size Considerations.
  • Electric Requirements.
  • Energy Efficiency.

Cooling Capacity

Cooling capacity should be your very first consideration before buying a window AC obviously. Cooling power is always measured in British Thermal Units, or BTUs, per hour–the basic measure of the thermal energy. For the best effectiveness and efficiency, opt with a unit which has a BTU level manufactured to fit your space. A window AC with little BTU power will run continuously to try to cool the large space and, in the process, will definitely eat up your energy budget. A window AC which is too large for your space won’t really cool but dehumidify your space evenly, leaving your room’s air susceptible to uncomfortable hot and cold pockets.

To find the perfect cooling capacity, calculate the size of the space you want cooled in the square feet. Then find the right number of BTUs.

  • Area to Be Cooled (Sq. Ft.)
  • Capacity Needed (BTUs Per Hour)
  • 18,000 BTUs to 21,000 BTUs would be perfect for a 1,000 square feet.

In addition, take these factors into consideration, if you want a more accurate size:

  1. Ceiling Height — The estimates above assume traditional 8 foot ceiling heights. You may need to increase your BTU level if your ceilings are higher than 8 foot.
  2. Sunlight — If sunlight comes directly into your room, increase your BTU power by 10 percent.
  3. Number of People — If more than 2 people regularly occupy the room? For each additional person, you will need 600 BTUs of cooling capacity.
  4. Kitchen — If you are going to install your window AC in a kitchen? you need to increase the capacity by 4,000 BTUs.


Most window AC models are manufactured to fit inside the standard double-hung windows. For step by step directions on how to install it through a window, check out videos and articles on How to Install a Window AC. Nonetheless, many models available out there can also be installed inside a custom created wall space with the special mounting hardware. This is a very useful alternative if your window’s dimensions are too small or too big or if you do not have a vertical sash windows.


Measure the exact dimensions inside the window frame, paying special attention to its width. Then, look for the maximum and minimum window width dimensions listed in the Air Conditioner’s specifications. Do not worry if your model exactly doesn’t extend to fit your window frame. Almost all window air conditioners come with installation kits, which includes side curtains to seal off the extra space which is left on every side of a window or the wall opening.


For wall installations, always make sure the model you want can accommodate this type of installation and that you have the suitable installation kit. Then, make exact note of the dimensions of the finished wall opening, which is listed in the product’s specifications. Use those dimensions for the wall opening. If required consult a professional. You can check available window Air Conditioners that can also be installed through a wall here.


When you air conditioner is completely installed, whether in a window or even through a wall, the window air conditioner will sit level inside that opening, with the warm air exhaust system on the outside and the cooling system facing inside, obviously. In addition, a lot window air conditioners feature a slide out chassis and also a rugged mounting sleeve that stabilizes and secures the unit, while giving you easy and convenient access to it for maintenance. All of the window air conditioners come with the detailed, easy-to-follow instructions for quick installation.

Electrical Requirements

Window air conditioners are more powerful than the other common household electronic appliances, make sure that your existing electrical system meets the requirements of the unit’s electrical needs. Most of the room air conditioners operate on 115-, 125- or 220- voltage circuits. Air Conditioners with the cooling capacities below 15,000 BTUs normally run on the standard residential (115- to 125-voltage) circuits. Window Air Conditioners with cooling capacities above 15,000 BTUs which normally run on the 220-volt circuits. With these particular models, you may require installing special electrical wiring or also seek out an electrician to help you.

Electrical requirements including amps, voltage, and watts will be listed in the specifications. Furthermore, the correct plug face type may be pictured or sometimes listed by its NEMA (National Electrical Manufacturers Association) classification.

Energy Efficiency

Energy star in general, the best window air conditioners are more economical choice than the central air conditioners. They usually cost less to purchase and if the size is correct, they are cheaper to operate over the long-term. To gauge the unit’s energy efficiency, look for the two things in the product’s specifications: Energy Star rating and EER number.

The energy star rated room air conditioners use nearly 10 percent less energy than the comparable models and save you some money on operating costs. These efficient Air Conditioners also have features which give you better control over the operation and the energy output. These includes the programmable timers, digital thermostats, and the multiple cooling speeds. Most of the states also offer rebates for the customers who buy an Energy Star model.

An EER (Energy Efficiency Ratio) measurement tells you how many BTUs the unit benefits for each watt of the power. Use this as a rule of the thumb, the higher the EER is, the more efficient the air conditioner is. According to the U.S. Department of Energy, you should also shop for the room air conditioner which has an EER of at least 10.0 for the best energy and the cost savings. Friedrich window air conditioners are als0 known for both their high EERs and the Energy Star-qualified operation.


Window air conditioners need periodic maintenance to keep them in the top condition. They can be accessible to outside the dirt and debris, which can acquire inside or on the back. Furthermore, the dust and particles will build up on air conditioner’s air filter added. If it’s left untreated, all of these things will eventually combine to shorten the effectiveness of your air conditioner.

To assure long lasting operation, clean it at least once per year thoroughly. A window Air Conditioner with a slide-out chassis make it convenient because all you have to do is to slide the unit out to access it. Most of the air filters are washable with the mild soap and water. For particular maintenance tips for your particular model, refer to your owner’s manual. For protection from the pests, some room Air Conditioners, like the Friedrich Kuhl Series, they are equipped with the mosquito traps which permit condensation to flow outside without letting the insects inside. So, you need to always look out for the window air conditioners which are easy and convenient to maintain.


As you have already seen the window air conditioner we mentioned in this article and all of that information you need to know beforehand. The best window Air Conditioner unit is the one which can cover the room you install without overdoing it. Even though it can be a little time-consuming it’s always better to measure the room and its overall temperature leaks twice before deciding on any model.

Besides being just silent, the quietest window air conditioners are also super-efficient. These models can cool down a room in a very quick succession, without making it so cold that you will shiver. And the best thing with this is that, some yearly maintenance, these appliances can last for years if not decades. All in all, every product is great and unique in its own and comes with amazing specifications. We hope you find the best window air conditioner for 1000 sq. feet.
