Your heating system is one of the most important parts of your home. Having a warm house is easy to take for granted when it "just works". Unfortunately heating units tend to break on the coldest days of the year, when they are working the hardest. There might be an easy fix for this issue or it could be something more serious. This is one of the benefits of doing preventative maintenance on your boiler. There are a lot of safety issues and costly repairs that can be avoided by doing so. Annual service of your boiler can increase its lifespan and ensure it is operating safely.
