👉 Retrofits are small improvements or modifications to existing systems, appliances, or buildings that enhance their functionality and reduce maintenance costs. These changes can include replacing worn-out components with new ones, upgrading heating, cooling, and lighting systems, or installing new features such as smart home technologies or energy-efficient appliances. For example, a homeowner might consider retrofitting an old, outdated HVAC system to improve its efficiency, install solar panels for renewable energy, or upgrade the insulation on their attic to prevent heat loss.
