Some homeowners do with a kit if service valves are installed. Diagnosing error codes and replacing sensors, igniters or gas components should be left to a pro.
Common causes of failure include mineral buildup from hard water, ignition problems, faulty flow sensors, clogged air filters, exhaust venting issues and electrical component failures. Regular maintenance, including descaling, can prevent most of these problems.
Regular professional maintenance, including descaling and checking all connections, is the best defense. Installing a whole-home water softener can also significantly reduce mineral buildup in areas with very hard water.
In homes with hard water and no softener, once a year is a good rule. Homes with a softener may go longer, but annual inspection is still smart.
