Don has helped me with numerous leaks and other plumbing problems when it's an emergency, he works hard to get us on his schedule promptly we really appreciate his great work ethic and honesty! We don't have that problem with our combo boiler. Getting an energy-efficient boiler is a great start to saving on heating, but what's the purpose of heating your home if the heat is escaping? Our engineers are always on hand for you. Serving bristol, southington,.
