Ideal Air Services Ghana Ltd experts says leaving the air conditioner on when you're away actually saves energy and money

As temperatures rise outside, many Africans rely on their air conditioners at home or their apartment to keep life from boiling them indoors. While air conditioners are great at cooling down homes, they simultaneously heat up electricity bills. This leaves many to wonder whether they should turn off their air conditioner when they leave home in order to save money. Basic logic would suggest a person should, but an expert says the opposite.

Mr. Nurudeen Ali Issaka, an HVAC specialist from Ideal Air Services Ghana Ltd, explains that while turning off the A/C when leaving your home sounds logical, the reality is that the home will heat back up as you’re gone and your A/C will end up using more energy trying to get your home back to the desired temperature compared to keeping it on to maintain its current state. He suggests that before you leave, you can adjust the temperature of the air conditioning unit to a slightly warmer temperature to help offset power costs while you’re away and then return it to the desired temperature when you return.

As the world gets warmer, air conditioning is seen more and more as a necessity by some cultures. The United States is home to 374 million A/C units, second only to China 569 million and Ghana with 1,030,255 million. Air conditioners are typically used in hot or humid climates, as expected, but are usually more common in areas with denser urban populations that have more people, asphalt, and cars which generate heat. Air conditioners are also more common in more affluent nations, too.

While Ghanaians are rising in air conditioner usage, most African countries have shied away from A/C. In fact, only one in ten European households have an air conditioner. The reluctance to embrace A/C has much to do with reducing energy costs, not taxing older electrical grids, and environmental impact. While it provides relief from heat, air conditioners typically contribute to climate change by being responsible for about three percent of greenhouse gas emissions. So, while air conditioners cool down our home, they warm up our planet, causing further need for them.

Fortunately, there are people trying to make air conditioners that are both more affordable and environmentally friendly. Ideal Air Services Ghana Ltd is developing A/C unit that cools the home with less carbon emissions. Depending on your climate, a heat pump might be a better, less costly alternative to air conditioning. Since 2022, scientists have been working on a new form of A/C unit that relies on a solid refrigerant which could significantly reduce energy consumption and lower environmental impact while still being effective at cooling your home.
