What type of maintenance should be regularly performed on gas appliances?

Regular visual inspections are essential for maintaining gas appliances because they help identify potential issues before they become serious problems. During these inspections, technicians can look for signs of wear and tear, gas leaks, corrosion, and other factors that could affect the appliance's safety and efficiency. Visual checks can include examining connections, vents, and the overall condition of the appliance.

While full energy audits may be necessary in certain situations to assess the overall energy efficiency of a building or system, they are not a routine maintenance task specifically for individual gas appliances. Scheduled pump replacements and water filter changes pertain to specific systems (like heating systems with pumps or water treatment systems) and would not apply broadly to all gas appliances. Thus, routine visual inspections are the most universally applicable form of regular maintenance for gas appliances, ensuring their proper function and safety.
