If you are in the market or are scouring the online store for purchasing an energy efficient air conditioner, you may be overwhelmed by the options available. The air conditioners available today are different and more efficient than the ones available a decade ago. Nearly every air conditioner these days comes with the claim of being “the best energy efficient air conditioner”, making it hard to choose the right one.
Fortunately,there are some features that an air conditioner must have for being energy efficient. Make sure you look for these features while buying a new AC unit for your home or office.
No size fits all when it comes to choosing an AC unit. It depends on the size of the room and the cooling needs that will be the appropriate for your home. A too small or too large unit will not only reduce the efficiency but will also shorten the life of the unit and will increase the utility bills.
High SEER rating
SEER (Seasonal Energy Efficiency Rating) is calculated by dividing AC unit’s cooling output for a particular season by the total amount of electricity consumed during the same season. The higher the SEER rating, the better will be the energy efficiency and lower the operating cost.
It is one of the most powerful features that every so-called “best energy efficient air conditioner” must have. Though it does not have a direct effect on the mechanical efficiency of the unit, it allows you to program the thermostat to maintain different temperatures as per your needs. This reduces the overall energy consumption.
Compressors use the maximum electricity as they need to work hard for squeezing out the heated vapors. The benefit of having a two-stage compressor is that it automatically compresses more when it is hot and less when it is cool. This results in increased energy saving.
Geothermal heat pump
Geothermal heat pumps are the ones which use earth as a heat sink. They send heat from a warm area to a cooler one. Though they can cost you more for the initial installation, they are 40% more efficient than the traditional air conditioners and let you save on monthly electricity bills.
Automatic fan delay
If your air conditioner is one that features the air handler and compressor turning off at the same time, there are good chances that some air is left in the ducts. However, an AC unit with an automatic fan delay switch will keep the air handler running for a specific amount of time after every cooling cycle. This results in pushing the remaining air into the living space.
As technology keeps on advancing, new features are being introduced to make the air conditioners energy efficient. Consider the above-given features while buying an air conditioner unit and try to remain aware of the latest features so that you can update your air conditioner to ensure enhanced efficiency and lower electricity bills.
