I've had several issues with my oil furnance over the years and Sean has rescued us every time! Sean is an expert heating and cooling systems guy and simply the best ive experienced. Prompt, knowledgeable, professional and goes to any length needed to get your system working again, truly cares about fixing your issue and doesnt leave you hanging. Ive dealt with several horizons guys who didn't know how to fix my furnance only to have Sean come out and fix it within a half an hour. I would reccomend Summit to anyone.
