What can be a consequence of using an improperly tuned gas appliance?

Using an improperly tuned gas appliance can lead to increased energy costs due to inefficient operation. When appliances are not properly adjusted or maintained, they may consume more gas than necessary to perform a given task, such as heating water or space. This inefficiency results in higher utility bills because the appliance is working harder and using more fuel to achieve the desired results.

Improper tuning can also lead to incomplete combustion, which not only wastes gas but can lead to dangerous situations, such as carbon monoxide production. Regular maintenance and correct tuning help ensure that gas appliances operate at optimal efficiency, minimizing energy consumption and costs. Therefore, the link between improper tuning and higher energy costs is clear in the context of appliance performance and economic usage.

In comparison, better air quality, longer appliance lifespan, and reduced noise levels are not directly connected to the effects of improper tuning; in fact, these aspects can often be negatively impacted if an appliance is poorly maintained.
