Most homeowners in America depend on their air conditioning system or a heat pump to keep them cool and comfortable through the different seasons. Since these two play similar roles in the home, most people struggle when making the decision of which to go for between them, especially when considering energy efficiency.
Suppose you are thinking of buying any of the two and you need help deciding, then this post is for you. Here we will take a look at the energy efficiency of heat pump vs an air conditioner. So keep reading.
What Are Heat Pumps?
Heat pumps are a type of central HVAC system that channels hot air out of your home in order to keep it cool. It can also reverse the flow by pumping hot air into your home to keep it warm.
Basically, heat pumps transfer heat from one place to another place where it is needed.
Heat pump systems can operate either as an outdoor unit or as an indoor air unit. They come in three main types,, which are air-source heat pumps, geothermal heat pumps, and water-source heat pumps.
What Are Air Conditioners?
Air conditioners are systems that cool an enclosed space by drawing hot air outside while returning cool air inside through the vents in your home. This creates a comfortable atmosphere in living spaces and improves the quality of indoor air as well.
Unlike heat pumps, there’s no reverse flow in air conditioners. That means they can not be used in heating the home. With air conditioners, you will need a different heat source, like a furnace,s to provide a warm atmosphere in your home.
Heat Pump vs. Air Conditioner: Which is Better?
Air conditioners can be very beneficial during hot seasons when you only need to regulate your indoor temperature. But the downside is they can only provide cooling to your home and may not be relevant when you need to keep your home warm. So during cold winter months, when outdoor temperature drops and you will need warmer air in your home, your air conditioners will be of no use to you. At the same time, the reverse flow function of heat pumps allows them to provide both heating and cooling, which makes them beneficial through different seasons of the year.
Heat Pump vs. Air Conditioner: Which Is More Energy Efficient?
Energy efficiency is a vital factor to consider when making a choice between an air conditioner and a heat pump. That is because the more energy efficient the system is, the less energy consumed, which also means lesser energy bills. So, it’s always best to go for the more efficient option when buying a cooling system.
You can know the efficiency of your cooling system by checking the seasonal energy efficiency ratio (SEER). This is simply calculated by noting down the total amount of heat removed from your home and then dividing it by the total amount of energy that is consumed by the system. Cooling systems with a higher SEER rating are usually more efficient.
Generally, heat pumps are a more efficient option than air conditioners when it comes to cooling your home, as they consume less electricity. They also function better than standard air conditioners in dehumidifying the air, resulting in lesser use of energy.
Why Are Heat Pumps More Energy Efficient Than Air Conditioners?
Under ideal conditions, heat pumps and air conditioners with the same SEER rating can keep your home cool using equal amounts of energy. However, air conditioners would have an efficiency problem under extremely hot temperatures.
An air conditioner is designed to cool your home effectively when there is not much difference between outdoor and indoor temperatures. But during hot seasons of the year, when outdoor temperatures exceed indoor temperatures by about 20 degrees, your air conditioner would be unable to function efficiently while cooling your home as they would consume more energy.
On the other hand, heat pumps are not affected by extreme outdoor temperatures. They can efficiently cool your home regardless of the differences in outdoor and indoor temperatures without consuming more energy.
Choosing between a heat pump or air conditioner depends majorly on what you need, where you live, and how much you’re willing to spend. If energy efficiency is what you’re looking for, heat pumps are the most ideal and energy-efficient option for cooling and heating your home. However, they cost more than air conditioners and may require more maintenance. Alternatively, while air conditioners are more affordable, they are not as energy-efficient as heat pumps. However, they are also effective and great for cooling your home with high outdoor temperatures.
