We had this company install a boiler system in 2014. There were problems with the initial installation and we have nothing but difficulties since. 15 service calls,six failed parts and inefficient heat for four winters. Efforts to resolve these difficulties have been increasingly difficult with both the service technicians and Service Manager so we changed companies in December 2017 and our system is working efficiently and all of the problems have been resolved. I don't recommend Captial plumbing and heating at all for major work in your home.
