Failure to inspect and maintain electrical connections and wiring in HVAC systems can lead to equipment failure, increased energy consumption, and safety hazards. Neglected connections can cause overheating, arcing, and even electrical fires, resulting in costly repairs, downtime, and potential harm to people and property. Moreover, neglected wiring can lead to reduced system efficiency, increased energy bills, and shortened equipment lifespan. Regular maintenance helps prevent these issues and ensures safe, efficient, and reliable HVAC system operation.
