“Vermont Gas came out this week for a gas leak outside and they fixed it and checked inside too. They said there is no charge to come because they want people to call for leaks! They were super nice and showed me an alert signal code on my heater and explained how I could monitor the problem to determine the type of error my heater is having. Then I was told about a service I can pay that covers repairs for labor and many parts, as well as an annual inspection during off season months for $140 annually. I signed up for it.
