Sure, you recycle your paper and always sort your plastics into the right container. But global warming isn’t just about what you throw away.

One of the biggest contributors to this phenomenon is the way we heat and cool our homes and offices.

In order to reduce the greenhouse gases that are affecting the Earth, we should look at our HVAC or heating and air conditioning systems. They are necessary to keep us comfortable. But these systems don’t need to hurt the planet.

One of the most important things you can do today is to research green heating and cooling systems. This article will show ten of the best heating and cooling systems that don’t add to global warming.

1. Passive Solar Energy Systems

To see the biggest source of green energy we have, all you need to do is look up. The sun is a constant and renewable source of energy for the planet. You can take advantage of it by using passive solar technology.

This is a simple technology that uses principles of heat transfer to power your home. The way it works is by collecting and storing the sun’s energy in a building’s walls, floors, and windows.

An easy way to implement passive solar is by using direct gain systems. The light streaming through a window will be converted into thermal energy.

Then the interior of the home stores the heat. At night, the stored heat is used to warm up the space.

2. Active Solar Energy Systems

If you want to make an even more sophisticated solar system, you can fit your roof with solar cells. These cells convert sunlight into energy. In turn, that energy is used to light the home, or heat and cool it.

These are a pricier option but over a longer time period, you will recoup your investment. Many places also have tax rebates and incentives in place to make it economically attractive to install these systems.

3. Biomass

You’ve probably already come across this next form of energy. Ever burned a wood fire to keep yourself warm? Biomass is an affordable green heating and cooling solution. It’s energy from trees, plants, and other living things.

Biomass heating systems work with the stored energy that plants and other organisms contain. They turn it into heat energy, while not having a detrimental effect on the planet.

4. Biodiesel

Biofuels are also a naturally-derived form of powering homes. While many people have used biodiesel for vehicles, it’s becoming more well-known for its clean-burning ability to heat homes.

Among its many advantages is the cost of biodiesel compared to oil. Oil prices are notoriously changeable, so using biodiesel could save on your energy bills.

Not only is it good for your wallet, it’s good for the atmosphere. This type of fuel releases fewer pollutants like carbon dioxide. It’s also sustainable since it comes from crops we grow anyway, like corn and soybeans.

5. Air Source Heat Pumps

Heat pumps are a great option for efficient cooling and heating. This is because they work by moving heat, not by using costly, polluting fuel.

The heat pump works by using a compressor and two coils. One coil is indoors and the other is outside. To heat the home, a liquid refrigerant from the outside pulls heat, which evaporates into a gas.

The indoor coil then condenses the heat back into a liquid. In winter a reversing valve can change the direction of the flow of the refrigerant to defrost the outdoor coils.

6. Geothermal Heat Pumps

Geothermal heat pumps work similarly to air source ones. The difference is that the geothermal pumps get heat from the ground.

These type of pumps have a number of advantages, including being quieter than a furnace and more affordable. You can read more about these two options to decide which is right for your home.

7. Radiant Floor Heating

Out of all the modern heating and cooling systems, we have now, there’s one you can get installed in your home right away. An invisible energy supply called radiant floor heating can reduce the amount of energy used to heat your home.

It’s powered by tubes or wires that run through the house’s floors. Since it’s evenly distributed, there’s a gentle and stable heat that’s also great to walk on.

You can choose from either electric or hot water as the heat source. In general, hot water is the most efficient but more expensive option.

8. Ice-Powered Air Conditioners

On the other side of the temperature spectrum are green cooling solutions.

The Ice Energy company has developed a device that can change water into ice. The unit makes the ice during the night and then stores it until the next day. It works with existing air conditioners, efficiently cooling the units’ refrigerant.

That stored ice is then used to cool the building. Using technology like this, electricity costs and overall energy consumption both go down.

9. Green Roofs

Green roofs are a popular eco-friendly option in Europe, and they are now becoming popular in the United States.

They work by putting a natural growing system on rooftops, a traditionally underused space. These benefit the building and environment in a number of ways. They include retaining stormwater, reducing flooding, and cleaning the air.

10. Hydronic Heating

One of the oldest ways to warm a house is with hydronic heating systems.

Modern ones use hot water that is run through pipes under floors or along baseboards. If you’ve ever seen an old radiator, you already know about at least one form of hydronic heating.

The Best Heating and Cooling Systems for Your Needs

The best heating and cooling systems for each household will vary. For you, it will be the option that’s most affordable which also maximize the weather you get in your location.
