Maintaining your system can help improve your unit’s heating efficiency, ensure fewer malfunctions or breakdowns, lengthen the life span of your unit, create a more comfortable environment, and deliver peace of mind when it’s time to heat your home.

Frequently Asked Questions

The average life span of a gas boiler is 10 to 15 years, but it all depends on how well you maintain and care for your unit. If yours has reached its life span or no longer operates efficiently to heat all parts of your home, then it may be time for a replacement.

Tuning up your boiler once a year will help you avoid any issues with the winter season. It’s best to schedule a maintenance visit in the fall so that way, if there are problems, they can be fixed before temperatures drop.
