In 2025, new HVAC regulations will come into effect specifically targeting the use of certain refrigerants that are deemed harmful to the environment. These new rules are expected to drive up the cost of HVAC systems that rely on more eco-friendly refrigerants, as manufacturers adjust to the stricter standards. As a result, replacing your existing system now with a current reliable model could save you significant money and hassle. Older systems that use current refrigerants may provide better efficiency at a lower upfront cost before the new regulations make newer systems more expensive. Acting now allows you to avoid the estimated 15-30% higher cost and complexity of upgrading later under the 2025 regulations.
