Renewable Energy HVAC and Its Environmental Impact

As the surge of COVID-19 continues, it’s expected that carbon dioxide emissions will remain lower than normal due to the recession in global energy use. Energy and electrical consumption are reduced because of lesser commercial and industrial demand. Residential energy will increase, however, especially in summer when homes turn their air conditioning on for a more extended period.

In 2020, 15.7 percent of overall residential electricity consumption came from space cooling in the United States. From that, it can be concluded that HVAC plays an essential role in determining the environmental impact of our homes.

Get To Know the New Renewable Energy HVAC Technologies


Continuous studies in science and technology have led humanity to more discoveries and inventions that promote improving our environment. With the damaging effects of climate change starting to be felt around the world, HVAC manufacturers today are more committed to providing people with environmentally-friendly products.

Heating and cooling systems are now often designed for renewable energy use. Here are some new HVAC technologies that harness renewable energy.

Geothermal Heat Pump

The geothermal heat pump is not really a newly invented technology, since it has already been in the industry for a while. However, the population using geothermal HVAC has been growing across the country, especially today, when people are looking for more efficient ways to heat and cool their homes.

This geothermal heating and cooling system utilizes natural energy directly from the earth to make your home either warm or cool. It pumps hot air into your home during cold times and removes it during hot days. It does not produce carbon dioxide and other harmful gases, which is perfectly healthy for the environment.

Ice-Powered Air Conditioning

Ice has a bright future in air conditioning. This new kind of air conditioning is a type of thermal energy storage system. How does it work? These systems have a tank of water that freezes at night. When day comes, that ice cools the existing air in the conditioning unit, lowering the amount of power required to cool the refrigerant.

By doing this, they cut down on the use of energy during times of peak electrical demand and store it for future cooling. Ice-powered air conditioning can reduce the power required for cooling by 30 percent. Hence, this process can significantly reduce electricity costs when the time of billing arrives.

Solar HVAC

For the past number of years, solar energy has grown, and is now widely used in commercial and residential spaces. Even heating and cooling systems can be utilized with solar energy, as well. This is an excellent way of controlling your home’s carbon dioxide emissions.

However, there are some drawbacks when you have solar HVAC. The light and energy from the sun only shines during the day. This poses limitations for the household in using their solar HVAC unless they have a storage system or tie it into the grid. Otherwise, the solar unit will not be able to operate at night.

All of these renewable energy HVAC technologies are already available in the market. In terms of maintenance, you can contact providers of HVAC services for professional maintenance and routine checks to keep your HVAC working efficiently.

Renewable Energy HVAC’s Significance in Lowering Environmental Impact

Technologies today can add up to a high cost for the environment, from our small appliances to the big ones like HVACs. They all typically run on energy sources that produce harmful emissions that can contribute to worsening environmental issues. Renewable energy HVAC can make a meaningful impact and improve our carbon footprints.

Instead of fossil fuel, renewable energy sources can significantly decrease carbon dioxide emissions and other greenhouse gases that cause global warming today. Heating and cooling systems today can now be low-emission, or even emission-free, with those renewables.

Refrigerants are required for traditional ACs to work. However, they contain hydrochlorofluorocarbons (HCFCs) that can deplete the ozone layer, leading to a rise in global temperatures. With the use of upgraded green HVAC, we can hugely reduce the use of refrigerants.

Green HVAC can be beneficial to our health as well. Emissions that degrade air quality will be reduced. It can also decrease the number of allergens in the house through recycling air. This means it can improve overall air quality on both a small and a large scale.

In Conclusion


The continuous production of renewable energy HVAC is extremely helpful in improving our environment. Installing these units in your house is already a big help to reduce the adverse effects of energy consumption on nature. Go green now with this green HVAC technology.
