3 best energy efficient window air conditioner

Energy-efficient window air conditioners are cooling units designed to provide effective cooling while minimizing electricity consumption. These appliances are suitable for cooling individual rooms or spaces, offering a cost-effective and energy-saving solution for staying comfortable during hot weather. Here are some key features and aspects related to energy-efficient window air conditioners:

  1. Energy Efficiency Rating (EER): Look for window air conditioners with a high Energy Efficiency Rating (EER). This rating indicates how efficiently the unit can cool a space while using a minimal amount of electricity. Higher EER values mean better energy efficiency.

  2. Energy Star Certification: Energy-efficient window air conditioners often bear the Energy Star certification. This label signifies that the appliance meets or exceeds energy efficiency standards set by the Environmental Protection Agency (EPA).

  3. Size and Cooling Capacity: Choose an air conditioner with an appropriate cooling capacity (measured in BTUs) for the size of the room you want to cool. An oversized unit can lead to inefficient cooling and excessive energy consumption, while an undersized unit may struggle to cool the space effectively.

  4. Variable Speed Fans: Many energy-efficient window air conditioners come with variable speed fans, allowing you to adjust the cooling output to match your comfort level. Lower fan speeds can save energy while maintaining a comfortable temperature.

  5. Programmable Thermostats and Timers: These features allow you to set specific temperature and operation schedules, ensuring that the air conditioner operates only when needed. This can help reduce energy consumption.

  6. Filter Maintenance: Regularly cleaning or replacing the air filter is essential for maintaining energy efficiency and air quality. A clogged filter can reduce the unit's efficiency and cooling capacity.

  7. Sleep Mode: Some models have a sleep mode that gradually adjusts the temperature and fan speed during the night to provide comfortable cooling without excessive energy usage.

  8. Directional Airflow: Adjustable louvers or vents allow you to direct cool air where it's needed most, preventing overcooling and increasing overall efficiency.

  9. Quiet Operation: Energy-efficient window air conditioners are often designed to operate quietly, minimizing noise disruptions in your living space.

  10. Installation: Proper installation is crucial for energy efficiency. Ensure that the unit is sealed properly in the window opening to prevent air leaks.

  11. Remote Control: Remote control capabilities allow you to adjust settings without having to manually operate the unit, enhancing convenience and energy efficiency.

  12. Cost Savings: Investing in an energy-efficient window air conditioner can result in long-term cost savings on your electricity bill, especially during hot summer months.

When selecting an energy-efficient window air conditioner, consider the size of the room, the specific features that meet your needs, and your budget. Reading user reviews and checking product specifications can help you identify a model that provides both efficient cooling and energy savings for your home.

What size Window Air Conditioner do I need?

Choosing the correct size of Window Air Conditioner for your home can be a tough decision. A BTU output that is too low will leave you feeling like your air conditioner is barely working. Buying a unit that is too large can cause you to spend more than necessary on your monthly utility bill. The chart on the left will give you a rough idea of the Window AC you need based on the size of your space.

Installing Your Window AC

If you have installed a Window AC before, the installation steps for this unit should be about the same. If this is your first time, we include step-by-step instructions in our user manual and have created a video guide to better help you out. You can also reach out to us directly so a member of our team can help guide you through the installation process.

Sleep Mode

Choosing between cool comfort and high-quality sleep is not a problem you want to deal with.

We have engineered our unit to be as quiet as possible while cooling down your room. In addition, you can use the Sleep Mode function on your remote. This feature adjusts the temperature of the unit throughout the night to an optimal sleeping temperature, giving you a head start to the day when you rise in the morning.

Smart Remote Control

A common problem with Window Air Conditioners is that the set temperature is never the same as the temperature where you are at. Your AC might say that it is set to 65° but it feels like the Sahara Desert on your couch!

By using the iFeel function on the remote, your Air Conditioner will use a sensor on the remote to determine how long the AC unit operates. Every 10 minutes the remote will send a reading back to your Air Conditioner to let it know how hard to continue running.

Stylish, Modern Design

The first thing that comes to mind when you think of “Window Air Conditioner” is probably not very pretty. We wanted to have a Window AC unit which not only cooled our space but also looked good while doing it! We hid those ugly exhaust grilles on the front and hid it behind a flat, sleek panel and replaced the faded yellow color with a vivid, brilliant white color. It may not be the Mona Lisa, but that doesn’t mean you can’t show off to all your friends.

Multiple Wind Directions

TOSOT Window Air Conditioners come with two separate horizontal louvers so that you can blow cool air in two different directions. If automatic is more of your thing, with one press of a button your TOSTO Window AC will also swing up and down to blow cold air at different angles in your room.

Safe and Efficient

Since it is Energy-Star rated your TOSOT Window Air Conditioner is not only effective at cooling your space, it also helps you save money on your utility bill. TOSOT Window Air Conditioners are also UL-approved, meaning they meet the highest safety standards for use in your home and around your family.

Three Products, One Box

What if I told you that by purchasing one Window Air Conditioner, you could get two other products for free? TOSOT Window Air Conditioners also comes with a dehumidifier and a fan mode, so you can create even more comfort in your home by using some of the additional product features. Look at you, you savvy shopper.
