National Grid Electric and Gas, Mass Save Energy Program, Home Works Energy, Adobe Energy review: Fujitsu split system

In 2016, through National Grid we were referred to Mass Save for an energy audit. Homeworks responded and we were thrilled with the education and service they performed to help two elderly and disabled seniors save money. We have central air throughout the house with the exception of one room added on afterwards. This 10X12 room required a separate unit which we purchased through Homeworks. Homeworks installed a "Fujitsu" split system. We live on the coast and according to other heating/cooling companies "Fujitsu" is not recommended for coastal homes because they rust out and become inoperable in a relatively short period of time. We are proof of this as our unit has had numerous service calls and each one we were told to replace the unit because it is inadaquate and runs poorly. The person from Homeworks who initially sold us the unit has been fired from Homeworks curiously and Homeworks no longer installs "Fujitsu" units. Interestingly after all this time going back and forth with all companies (National Grid, Mass Save, Homeworks Energy, Abode Energy and others) we have been offered a 10% DISCOUNT off a $199 contract going forward for them to maintain a unit which neither heats nor cools. This ridiculous offer ($19.90) did nothing but make a bad situation worse. We are elderly and on a fixed income and after 6 years we have been told there is nothing more anyone can do for us.
