Energy Efficiency Ratio (EER): The Ultimate Guide

The Energy Efficiency Ratio (EER) is a key indicator of the efficiency of a given appliance. It provides consumers with the ability to compare the energy efficiency of different types of air conditioning and heating systems, as well as other appliances. Knowing the EER of an appliance can help determine what product is best suited to meet their needs. In this guide, we will explore the Energy Efficiency Ratio and explain how it can help you determine the most efficient product for your home or office.

What is the Energy Efficiency Ratio (EER)

The Energy Efficiency Ratio (EER) is a measure of the efficiency of a given appliance or system. It is calculated by dividing the cooling energy output of the appliance by the energy input needed to run it, both of which are expressed in British Thermal Units (BTUs). The higher the EER, the more efficient the appliance or system is. The higher the value, the more energy or electricity the appliance or system uses to do the same amount of work. In other words, if two products have the same BTU output, the one with the higher EER will be more efficient.

How to Calculate EER

The EER of an appliance or system can be calculated using the following formula:

EER = Capacity (BTUs) / Input (BTUs)

The capacity is the BTU output of the appliance or system, while the input is the amount of energy (usually measured in BTUs) it needs to operate. Generally speaking, the higher the EER, the more efficient the product will be.

Factors that Impact EER

The EER of an appliance or system is affected by several factors. Room size, climate conditions, type of insulation, and air leakage all play a role in determining the efficiency of a given product. Additionally, the type of system can have an effect on the EER rating. For example, heat pumps are typically more efficient than air conditioners or furnaces, and include their own EER rating. It is essential to factor in all of these variables when making decisions about the best energy-efficient appliance or system for your home or office.

Why is EER Important?

The Energy Efficiency Ratio (EER) is a valuable tool for consumers as it shows the relative efficiency of different products. Knowing the EER rating of an appliance or system can help you decide if the product is a suitable option for your home or office. Additionally, an efficient system with a high EER can save homeowners money in the long term.

Finally, understanding the Energy Efficiency Ratio can help consumers select the appliance or system that best meets their needs. They can quickly compare the efficiency of different products and make an informed decision about which one is right for their home or office.

Common Questions About EER

What is a Good EER Rating?

A good EER rating is a value of 10 or higher. This indicates that the appliance or system uses 10 btu of energy to provide 1 btu of cooling output. Energy-efficient systems typically have a higher EER rating than their less efficient counterparts.

Will a Higher EER Rating Increase My Energy Bills?

Efficiency is key when it comes to saving energy and money on energy bills. An efficient system can save consumers money in the long run by using less energy to provide the same amount of cooling output. Therefore, a higher EER rating does not necessarily equate to higher energy costs, in fact often the opposite is true.

Are Heat Pumps More Efficient Than Air Conditioners?

Yes, heat pumps typically have higher EER ratings than air conditioners. Heat pumps are able to move heat from one place to another, rather than generate heat themselves. This means they use less energy, resulting in a higher EER rating.

What Other Factors Should I Consider When Choosing an Appliance or System?

In addition to the Energy Efficiency Ratio, there are a few other factors to consider when selecting a product. Noise levels, ease of maintenance, availability of repair services, and the size of the unit are all important considerations. Additionally, it is important to research any potential product before making a purchase to ensure that it is the best option for your home.


The Energy Efficiency Ratio (EER) is an essential tool for anyone looking for a product or system to keep their home comfortable and energy-efficient. Knowing the EER rating of a product can provide insight into the efficiency of the system and help homeowners make an informed decision about the best option for their home or office. Additionally, energy-efficient systems have the potential to save money in the long term and selecting one with a high EER can help ensure an efficient choice is made. If you are looking for an appliance or system to keep your home or office cool, considering its EER is a great way to make sure you select the right product for you.

Tips For Achieving Better Energy Efficiency Ratings

Maintaining energy efficiency in your household appliances and HVAC systems is essential for controlling your energy costs and minimizing your environmental impact. Fortunately, there are several manufacturer, local appliance companies, and HVAC technician recommendations that can help you manage and improve your Energy Efficiency Ratio (EER). Here are some of the best practices for maximizing efficiency in your home.

Change the Filters

One of the simplest yet most effective ways to increase the efficiency of your HVAC system is to change the filters regularly. Changing your filters at least once every 3 months ensures that your system is running with as close to maximum efficiency as possible. This will also help to reduce the dust and debris in your home, leading to better air quality and a more comfortable living environment.

Upgrade to a High-Efficiency Model

If you have an older HVAC system, it may not be running optimally. Consider upgrading to a high-efficiency model, which can lead to energy savings of up to 30 percent. High-efficiency models with the latest features will help to minimize energy use and reduce your overall energy costs.

Check for Leaks

Any kind of leaky ductwork or piping can lead to an inefficient HVAC system. Make sure that any gaps or cracks in the piping are properly sealed, and be sure to install insulation if necessary. Leaks cause a drop in efficiency that can’t be easily reversed, so make sure that your ducts are completely sealed before you run your system.
