The answer to 'which is better replacement or' is that in most cases, replacing an older HVAC system is better than repairing it. Replacement offers several key benefits, including improved energy efficiency, better indoor air quality, and more reliable performance.
While repairs can temporarily fix an issue, they don't address the underlying age and wear of the system. Newer HVAC units are designed to be much more energy-efficient, which can lead to significant long-term savings on utility bills. They also incorporate advanced features for better temperature control and air filtration. Plus, a full replacement typically comes with a manufacturer's warranty, giving you peace of mind.
