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.
