For example swapping R-12 for R-134a in a chiller is compatible with an approved lower-GWP refrigerant, which can reduce upgrade costs. You can sell your old refrigerant to help cover the cost of new bearings, oil, and replacement refrigerant.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"%C2%B7_When_Replacement_Delivers_Long-Term_Value\"><\/span>\u00b7 When Replacement Delivers Long-Term Value<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Replacing a chiller offers long-term value if your chiller breaks down more often, runs less efficiently, or relies on a high-GWP refrigerant. When you start seeing frequent alarms, oil contamination, or unstable cooling, it means the system is aging. Replace it with a new low-GWP chiller to improve energy efficiency, reduce maintenance costs, ensure regulatory compliance, and provide more reliable performance.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"FAQs\"><\/span>FAQs<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-29553\" src=\"https:\/\/chillerone.com\/wp-content\/uploads\/2026\/07\/FAQs-2-1.jpg\" alt=\"FAQs\" width=\"1280\" height=\"720\" srcset=\"https:\/\/chillerone.com\/wp-content\/uploads\/2026\/07\/FAQs-2-1.jpg 1280w, https:\/\/chillerone.com\/wp-content\/uploads\/2026\/07\/FAQs-2-1-768x432.jpg 768w\" sizes=\"auto, (max-width: 1280px) 100vw, 1280px\" \/><\/p>\n<h4><span class=\"ez-toc-section\" id=\"What_are_low_GWP_chiller_refrigerants\"><\/span>What are low GWP chiller refrigerants?<span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p><a href=\"https:\/\/chillerone.com\/use-of-low-gwp-refrigerants-in-chillers\/\">Low GWP chiller refrigerants<\/a> are known for their low global warming potential, which reduces the environmental impact of chiller systems while providing reliable cooling.<\/p>\n<h4><span class=\"ez-toc-section\" id=\"Can_I_continue_using_chillers_even_with_the_phased-down_refrigerant\"><\/span>Can I continue using chillers even with the phased-down refrigerant?<span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p>Yes, if they are properly maintained and comply with local regulations.
