For many households and businesses in Ghana, the real cost of owning an AC is not the amount paid at the showroom or the installation fee. It is the electricity bill that follows every month for the entire life span of the unit’s operation. As temperatures continue to rise and air conditioning becomes increasingly necessary, many consumers believe that owning an AC is an unavoidable cost of staying cool in a hot environment. But a significant part of that bill is not the cost of cooling your room alone. It is the cost of a unit that does not know when to stop wasting electricity, running on technology that is decades old and built around chemical refrigerants, which the world is now moving away from.
A conventional split AC commonly found in homes and offices often uses cooling technologies and refrigerants like R22, R410A, and R32, which usually consume high amounts of electricity. Most of these units rely on a fixed-speed compressor that can only operate at full power or switch off completely and then turn on again. This constant switching on and off draws a surge of electricity each time the compressor kicks back in, making the system inherently inefficient and keeping energy consumption high throughout operation.
A split inverter AC is built differently with inverter compressor, which is “smart” and speeds up when cooling is needed and slows down once the room reaches a comfortable temperature. The result is that the AC uses only as much electricity as the situation requires. That efficiency alone can make a significant difference to how much you pay for your electricity bill every month.
Combining an inverter AC with the superior performance of the R290 refrigerant, you have an AC that delivers significantly higher energy efficiency than 98% of the conventional units Ghanaians are running today. Moreover, R290 is a natural refrigerant with no negative impact on the environment, the ozone layer, and almost zero climate impact. Therefore, R290 ACs come with an eco-refrigerant label of EPA.
According to performance assessment and comparisons conducted by participating importers, 3-star R290 split-inverter AC, rated under Ghana’s Energy Efficiency Standards and Labelling framework (L.I 2458) can save consumers up to 67% on electricity costs per year, compared to running a standard conventional R410A or R32 AC unit. EPA Ghana’s published data shows average electricity cost savings of between GH¢2,000 and GH¢4,000 per unit per year based on approximately 4,000 running hours per year and electricity savings ranging from about 1,470 kWh up to 2,256 kWh annually when compared to standard conventional inverter split AC units. For households and businesses that rely heavily on AC throughout the year, these savings can accumulate significantly over the operational lifetime of the unit.
For businesses, and offices running multiple split AC units, the combined savings across an entire facility can make a material difference to monthly operating costs. For example, if a company has 10 split-inverter ACs, the savings can be up to GH¢ 20,000 and GH¢40,000 per year on electricity costs alone. Improving cooling efficiency is becoming increasingly important as energy demand continues to grow alongside rising temperatures and urban expansion.
Complementing the electricity savings, the 3-star R290 split-inverter AC has a financial incentive mechanism designed to lower the upfront cost of purchase. The Ghana Green Cooling Programme, supported by the Swiss KliK Foundation and implemented by EPA and GIZ is incentivising a minimum of GH¢ 1100 per AC unit and is actively encouraging both households and businesses to make the switch. The R290 split-inverter ACs are available in showrooms across Ghana, through importers who have partnered with the Ghana Green Cooling Programme. These include Hisense, Midea (Electroland), GREE (Unique-Home-Appliances), and in the near future, Haier (Electromat/Somotex). Think of it this way, an R290 split-inverter AC bought today starts saving you money every month. The lower electricity bill will not be a one-time bonus; it will be a recurring return for the life span of the unit, while also contributing to Ghana’s broader commitment to cleaner, more climate and environmentally responsible cooling.
Consumers should also be aware that the R290 refrigerant, like other refrigerants including, R32 requires proper technical handling during installation, servicing, and decommissioning. Refrigerants contained in ACs like R22, R410A and R32, when leaked into the environment, can contribute significantly to global warming. To address this, certified technicians are being trained to safely recover refrigerants before old units are dismantled. Therefore, it is important that consumers give their old AC to the trained technician so it can be recycled accordingly.
Now, as demand for cooling continues to grow in Ghana, due to rising temperatures, the transition toward more energy-efficient, climate and environmentally friendly technologies would play an increasingly important role in the country’s future cooling sector.
