provided fantastic strategic economic and environmental advice. I have purchased a few Sanden hot water heat pumps, Daikin air conditioners heat pumps and also the low flow shower heads for several properties and have had a great responses from all of the residents and including myself who have all those products in my house too.... very happy to recommend if you need to have a whole house strategy or get bits and pieces done. Its nice to work with Matthew and get advice from someone who knows the products inside out.
