What could be a serious consequence of ignoring appliance performance issues?

Ignoring appliance performance issues can lead to serious safety hazards, one of which is the potential for gas leaks. Gas appliances that are not functioning correctly may not burn fuel efficiently, which can lead to incomplete combustion, increased carbon monoxide production, and ultimately, hazardous leaks. These leaks can pose significant risks including fires, explosions, or exposure to toxic gases which can be harmful or even fatal to occupants.

In contrast, increased appliance efficiency is not a possible consequence of neglecting performance issues; typically, such neglect would result in decreased efficiency. Higher monthly utility bills may indeed occur as performance issues usually lead to appliances using more energy. However, the critical safety issues arising from potential gas leaks far outweigh these financial consequences. Minor inconveniences, while potentially disruptive, do not carry the same severity in terms of health and safety risks. Thus, acknowledging and addressing appliance performance issues is crucial to prevent serious consequences.
