What is the primary advantage of using recovery machines?

The primary advantage of using recovery machines is that they significantly reduce the environmental impact from refrigerants. Recovery machines are designed to safely remove refrigerants from cooling systems without releasing them into the atmosphere. This is crucial in preserving the environment, as many common refrigerants have been identified as ozone-depleting substances or potent greenhouse gases. By capturing these refrigerants, recovery machines help prevent harmful emissions and contribute to compliance with environmental regulations aimed at protecting the ozone layer and mitigating climate change.

Addressing the context of the other options, while improved energy efficiency, lower installation costs, and increased cooling capacity may be important aspects of HVAC systems and practices, they are not the primary focus of recovery machines. The main purpose of these machines is about handling refrigerants responsibly to minimize environmental harm.
