Practical steps you can do today. If a MiHT visit would help, it will say so. If not, it will say that too.

Made by an Auckland team that looks after home energy systems.

MiHT cleans, maintains and checks the ventilation, heat pump and solar systems already in Auckland homes. MiHT never installs or sells new units, so your result only points to work that is worth doing.
