"Fantastic advice environmentally and economically in a very strategic whole of house approach. I have done a few Sanden heat pumps, Daikin air conditioning units, and Methven satin jets low flow shower heads with Matthew. I am very grateful for his advice and help in delivering great outcomes in all the properties I worked with him on so far. He even went further and fixed other problems on things that weren't working and supplied by other trades at the house, he is a great person to work with and highly recommend."
