Ignoring ice buildup in an HVAC system can lead to severe consequences, including reduced system efficiency, increased energy consumption, and even complete system failure. Ice buildup can also cause water damage, corrosion, and rust, leading to costly repairs or replacement of system components. Furthermore, ignoring ice buildup can compromise indoor air quality and pose health risks to building occupants. It’s essential to address ice buildup issues promptly to prevent these consequences and maintain a safe and healthy indoor environment.
