Look for Energy Star certification

One of the most important factors to consider when searching for an energy efficient air conditioner is the Energy Star certification. This label, developed by the U.S. Environmental Protection Agency (EPA) and the Department of Energy, signifies that a product meets strict standards in terms of energy efficiency and environmental impact.

For example, let’s say you are considering two similar air conditioning units – one with an Energy Star certification and another without it. By opting for the Energy Star certified unit, you could save significantly per year on your cooling costs as compared to using a non-certified model.

Over the lifespan of your air conditioner, these savings can add up considerably – not to mention the added benefit of reducing greenhouse gas emissions associated with excessive energy consumption.

Consider the SEER rating

When shopping for an energy efficient air conditioner, one of the key factors to consider is the SEER rating. The Seasonal Energy Efficiency Ratio (SEER) measures an AC unit’s cooling output per watt of electricity used.

A higher SEER rating indicates a more efficient and cost-effective system.

It’s important to keep in mind that higher SEER ratings typically come with a higher price tag upfront. However, investing in a more efficient air conditioner now can pay off in the long run through lower monthly energy bills.

Additionally, some states offer rebates or incentives for purchasing high-efficiency units, which can offset some of the initial cost.

Properly size the unit

Properly sizing your air conditioning unit is critical to maximizing energy efficiency and minimizing cooling costs. An oversized unit will cycle on and off frequently, wasting energy and failing to effectively dehumidify your home.

Conversely, an undersized unit will struggle to maintain a comfortable temperature, resulting in excessive wear and tear on the compressor. To determine the appropriate size of your AC unit, you must consider factors such as the climate where you live, the size of your home, insulation levels, the number of occupants, and windows.

For example, if you live in a hot southern region with high humidity levels like Florida or Texas but have good insulation throughout your home and only use it during peak periods where several people are present inside at once, then sizing for 1 ton per 500 square feet should be sufficient.

Types of energy efficient air conditioners

There are several types of energy efficient air conditioners to consider when choosing the best option for your home. Window units are a cost-effective and efficient choice for smaller spaces, while portable air conditioners offer flexibility in terms of placement.

Split-system units provide excellent cooling and come equipped with an outdoor unit and an indoor evaporator coil. If you’re looking for whole-house cooling, consider residential central air systems, which can keep all rooms at a consistent temperature while improving indoor air quality.

Finally, inverter technology offers a more eco-friendly option as it adjusts its speed according to the room’s needs rather than continually cycling on and off like traditional ACs.


In conclusion, purchasing an energy efficient air conditioner is a smart decision for homeowners looking to save money and reduce their carbon footprint.

By following this buyer’s guide, you can make an informed decision that benefits both your wallet and the environment.
