Deciding whether to repair or replace your HVAC system can be challenging. In general, if your system is less than 10 years old and the repairs are minor, repairing it is likely the more cost-effective option. However, if your system is over 10 years old, requires frequent repairs, and is no longer energy-efficient, it may be time to replace it. Consulting with a reputable HVAC technician can help you make an informed decision based on your specific needs and budget.
