A furnace is one of the most important parts of a home heating system, especially in colder areas like Rhode Island where reliable winter warmth is essential.
Whether you own a gas, electric, or oil furnace, understanding how the system works can help you maintain it better, avoid breakdowns, and make informed decisions about repairs or replacements.
In this guide, we explain everything from how a furnace operates to common issues and maintenance tips, so you can keep your home comfortable through the heating season.
