Why maintenance is important

During maintenance, we check for carbon monoxide and safe combustion, clean the boiler and adjust it for optimal performance. A well-maintained boiler uses less gas and is less likely to break down at the worst possible moment.

How often is it needed?

For most boilers, a maintenance service is sufficient once every one to two years. Manufacturers often set this as a condition for the warranty. With a maintenance contract, we schedule it automatically.
