When choosing an AC unit, you should have a basic understanding of how air conditioners work. No matter what 
type of AC you purchase, they both take in gas, convert to liquid and then convert it back to gas again. The unit uses chemicals called refrigerants. Window units funnel this air out of the window and simply expunges hot air out of the way.
Window air condition units are stored outside of your living space, which is a great way to reduce clutter. They are also energy efficient, which means you get more cooling power per BTU. Window air conditions can also be installed through the wall which doesn’t really need an actual window space. Purchasing one is a great way of reducing your energy bills in warmer months yet efficiently cooling your home.
If you want to beat the heat and avoid your energy bills, skyrocketing, look no further!

Benefits of using a Window Air Conditioner
- Low cost
They are affordable not only to purchase but also to operate on a monthly basis. The overall cost of the unit depends
on the brand of choice, the features it has as well as its BTU capacity. To understand how much an air conditioner is going to cost, you should figure out the square footage of your room. The bigger the square footage, the more BTU capacity you need. The two factors that factor into the cost are:
Brands
While there are many manufacturers out there offering the same products, some do the job better than others. We have carefully curated a list which will help you choose from the best models out there.
Features
Some features are a necessity and some are frivolous. Based on your needs, you will choose the ones that work best for you. We have also included essential features for all air conditioners.
- Energy Efficient
Most window air conditions have an excellent energy efficiency ratio (EER) which helps give people an understanding of how much they are capable of cooling versus the amount of energy they consume. In order to maximize your energy savings, you should look for a window unit with a high EER rating. Ideally, you should consider an A/C unit that is Energy-Star Certified – this is a program established by the U.S. Environmental Protection Agency.
- Easy to Install
The installation process is easier than most. The process may differ depending on the model you purchase, but it is still quite straight forward. All parts and instructions are a part of the purchase and after that, the consumer just needs to follow a step by step process. While it is possible to install on your own, it helps to have one other person to assist.
- It does not occupy much space
Since it is designed to fit windows, it does not use up any square footage at home. It does unnoticed and doesn’t interfere with the interior aesthetic.
- This is great for supplemental use
This is a strategy employed by consumers looking to save money on their energy bills. Instead of using an air conditioner to cool the entire home, including those that no one is using, you can instead use a supplemental air conditioner to cool the room that you are sitting in.
- It has multi-functional use throughout the year
These window units can provide both heating and cooling for the home. This dual function makes them an excellent addition of one’s home. Some units also double as air purifiers. These units have anti-microbial or HEPA filters which help reduce allergens, other airborne particles and odours. This allows users to breathe in pure air.
- They are relatively portable
Since they are easy to install they can easily be transported from one room to another. The units can be transported even if you shift homes.

Features of a Window Air Conditioner
It is a good idea to keep in mind features that should be typically available in a window A/C.
- Thermostat
This is what allows you to control the cooling output. Higher-end models feature digital thermostats that read selected and actual temperatures. Basic models include a mechanical thermostat that uses a dial to select temperatures depending on the direction in which you turn it.
- Adjustable Fan Speed
Being able to adjust your fan speed affects the rate at which your space cools down. You can select a couple of fan speeds. That, in turn, affects the amount of noise created by the unit.
- Remote
A remote control allows the user to operate the unit without using the controls that are mounted on the AC. A remote
should be able to let you control the temperature while others also show temperature control on the remote. Other units also include a magnetic hold on the side so that the remote is not misplaced.
- Programmable Timer
This timer allows you to set a delayed start and stop time. This manages energy consumption and can be set in one-hour intervals. They can go up to either 12 or 24 hours.
- Air direction control
The vents allow you to manipulate the direction the air is blown from the unit. That way you can optimize the airflow of the space.
- Filter Type:
Standard
This is the most common type of filter that needs to be replaced periodically in order to ensure proper airflow and filtration.
Washable
These can be cleaned in a kitchen or bathroom sink in order to avoid replacement. They are durable and can be washed many times.
- Energy Star Rating
Units with this rating can operate 15% more efficiently compared to units that aren’t.
Things to consider when purchasing
- Cooling Capacity
This will be measured in BTUs (British Thermal Units), per hour i.e. the basic measure of thermal energy. Stick to a unit that is designed to fit your space. Calculate the size of the space you want to be cooled in square feet.
- Installation
Most window AC models are designed in order to fit standard double-hung windows. However, many models can be
installed inside a custom created by measuring window dimensions or dimensions of finished wall openings.
- Electrical Requirements
Make sure that your existing electrical system meets yours unites electrical requirements. Most room air conditioners operate on 115,125 or 220-volt circuits. Electrical requirements include voltage, amps and watts in the specifications.
- Energy Efficiency
They cost less to purchase and are cheaper to operate in the long term. Look at the Energy Star Rating or the EER number before your purchase. These air conditions use 10% less energy compared to other models and therefore save your operating costs. They also give you better control over operations and energy output. The EER tells you how many BTUs the unit uses for each watt of power. The higher the EER, the more efficient the air conditioner.
- Maintenance
These units need to be maintained periodically in order to remain in top condition. To make sure that you can use them long term, clean the unit at least once per year. Most air filters are washable with soap and water. For specific maintenance tips, refer to the instruction manual.
