Montes de Energia - Energias Naturais

i put a one star because there is no option of a no star.The management of this company we feel is hell bent on extracting as much money as it can from anyone unlucky enough to have had any sort of installation and unfortunately that installation showing faults. Any guarantee you get from this company is written on dissolving paper because if anything goes wrong with your system either that part wont be covered under the guarantee ( not found any that are). Or the labour which is not part of the guarantee is extortionatly expensive! We have had two problems with our system, both of them costing us a great deal of money whilst still in the warranty period. Plus the workmanship of the technicians" is left under the heading of questionable!! Both times they left us with major leaks and refused to come back!!"
