Kevin Dwyer installed our central heating boiler in 2010. A very good professional job. We call him every year to service the boiler and it has worked splendidly. This year, for the first time, there was a problem. Kevin came promptly. He identified the problem immediately, a valve needed to be replaced. He went out to get the valve, returned quickly and fixed the problem straightaway. In ten years we have always found Kevin to be friendly, reliable and professional. We recommend him highly.
