A/c systems are normally powered by electricity, which is made from nonrenewable fuel sources. Using electricity requires a large amount of energy, which produces co2. At extreme levels, this greenhouse gas can trap heat near the world’s surface area. This can contribute to such environment damage as global warming. So when you use an a/c unit, you’re contributing to greenhouse gas emissions. Nevertheless, newer models are more energy efficient and use less electricity than older models.
Is an Out-of-date Air Conditioner System Worse for the Environment?
If your HVAC system is outdated and inefficient, it will likely burn more electricity than newer systems. This may be using more energy than needed. This suggests that you’re paying more money on your power bill while producing more greenhouse gas emissions into the atmosphere. And if they have not been maintained properly, they can leak refrigerant into the environment. This is an environmental risk in addition to possibly hazardous to your health if it’s inhaled or touched.
How to Reduce Your Impact on the Environment
A/c units have a considerable impact on the environment and can cost more than other types of cooling systems. The good news is that there are ways to lessen your impact on the environment.
Air conditioners can be recycled and parts can be reused. The EPA approximates that 50 percent of units are still in working order after 10 years. This means they could be recycled instead of disposed. In addition, the majority of air conditioners are energy efficient, so it makes sense to keep them operating as long as possible. When you’re ready to replace your unit, purchase an Energy Star certified unit that complies with strict requirements for energy efficiency, performance and indoor air quality.
Here are some ways to minimize your impact on the environment with your HVAC unit:
- Use a programmable thermostat and set it to 78 degrees or higher when you’re not home. This will allow the air conditioning system to run less frequently, which lowers its energy usage and lowers your utility bills.
- Clean or replace filters routinely because filthy filters restrict airflow and reduce performance.
- Use fans when possible instead of switching on the a/c system. Fans cool people by distributing air around the body, while central air cools entire rooms by removing hot air from inside the house and replacing it with cooler outside air through vents throughout your home. If you use fans during hot weather, turn them off when using your central a/c system to prevent unnecessary energy use when cooling needs are biggest.
New Air Conditioners have Greatly Improved Ecological Ratings
Today’s air conditioners use about 2 percent of all electricity consumed in the United States. They account for about 6 percent of all energy usage in houses, according to Consumer Reports. The magazine states that’s because newer designs use far less energy than older ones did.
The EPA states that new air conditioners have improved ecological ratings. It states that an Energy Star-rated unit uses at least 15 percent less energy than a basic model and has features like timers and remote controls that let you change temperature levels from anywhere in your home– and even when you’re far from home The agency adds that Energy Star-rated units also use less water because they don’t run until they reach their preferred temperatures.

As you shop for a new air conditioning system, you may see that some models have an Energy Star rating and others do not. What’s the difference?
