When to Replace Your HVAC System
Your HVAC system may need replacement if it’s over 15 years old, even if it’s still running. Older cooling systems typically consume 20-40% more energy than modern systems, leading to higher energy costs. Units manufactured before 2010 using R-22 refrigerant require updating due to environmental regulations.
Watch for performance issues like uneven heating and cooling between rooms, unusual noises, or frequent cycling. Whether you have a traditional system or ductless mini-split, weak airflow and poor humidity control often signal declining system health. If your monthly energy bills have increased significantly despite similar usage patterns, your system’s energy efficiency may be compromised.
Consider replacement when air conditioning repair becomes frequent or expensive. Multiple maintenance services within six months, repairs exceeding 50% of replacement cost, or difficulty finding replacement parts all indicate it’s time for a new system. Major heat pump failures, especially in the compressor or heat exchanger, often make replacement more cost-effective than repairs.
