Best Tips for Choosing the Most Efficient Cooling System

While it’s wonderful to keep your home cool while the weather is sweltering, it isn’t nice to get your power bill at the end of the month and see how much it costs you and the environment. Air conditioners are a marvel of contemporary technology. They do, however, have a cost per kWh. 

Tips on Choosing Efficient Cooling Systems

So how do you go about choosing the most efficient cooling system for your home or office? Here are a few factors the ac tune-up professionals say you should consider.

Smart Thermostats

Today, most air conditioners allow you to customize your temperature preferences. Setting your air conditioner to 78 degrees Fahrenheit, as recommended by Energy Star, a program administered by the US Environmental Protection Agency and the US Department of Energy to encourage energy efficiency, is the best way to cool down without increasing your energy bill. 

When you use a smart thermostat, you can not only choose the appropriate temperature, but you can also control when the air conditioner goes on and off based on when you are at home.

Energy-Saving Settings

An energy-saving mode is included in the most energy-efficient air conditioning equipment. This option will switch off both the compressor and fan once the temperature in your room reaches the temperature you’ve specified. Don’t hesitate if you can get a smart air conditioner with a voice assistant like Google or Alexa. You may always turn it off or modify the settings remotely if you fail to do so before leaving the house.

Make and Model

Even the most energy-efficient air conditioners used up to 50% more electricity than air conditioners manufactured today only 40 years ago. Purchasing a more contemporary model can help you save up to 40% on energy. So, do you have to update your air conditioner regularly to ensure that you have the most energy-efficient unit? 

Of course not; if you want to keep your power use low at all times, a portable evaporative air cooler is the way to go. These devices provide the best value for money. Furthermore, the cartridges only need to be replaced every few months and are as good as new!


The acronyms EER and SEER stand for ‘energy efficiency rating’ and ‘seasonal energy efficiency rating,’ respectively. EER stands for energy efficiency with 100% cooling load, 50% humidity, and a temperature differential between 85 and 90 degrees Fahrenheit all year. The SEER is a metric that assesses energy efficiency in the summer months from June to August. 


You should choose the equipment with the best energy efficiency rating to save the most energy. For instance, an air conditioner with a 12 EER rating is extremely energy efficient.

Calculate Cooling Capacity

Even the most energy-efficient air conditioner might start squandering electricity when utilized in the incorrect room. BTUs (British Thermal Units) measure cooling capability. If you use powerful equipment in a small room, it will consume energy unnecessarily. 

For larger rooms, a less efficient device will take far too long to reach the necessary temperature and need far too much energy to maintain it. Multiply the room’s square footage by 25 to get the needed BTUs for your perfect air conditioner. You may also use this BTU calculator online.

Stay Clever to Stay Cool

While air conditioning may be your first choice for cooling, numerous other options consume less energy. In all but the harshest regions, good insulation, energy-efficient windows and doors, daylighting, shading, and ventilation will typically keep dwellings cool with minimal energy consumption. You should learn about the basics of heating and cooling before deciding on a cooling system. 

Any discussion of air conditioner ‘efficiency’ and how different types compare is difficult, mostly because different cooling technologies offer very different types of ‘cool,’ but also because efficiency levels – particularly of refrigerative air conditioners – can vary significantly even between brands and models. Similarly, where they’re situated and how they’re utilized might have a significant impact.
