Bunch of Thieves run this place. " Replace Freon in thermostat" $195. There is no such thing as Freon in thermostat. these devices are all electrical and there is no refrigerant in the thermostat. besides the upkeep of the air conditioning is the responsibility of the landlord. Beware when you move out they will charge you for things they don't perform. Complained to their corporate office and they were also useless. Stay away there are other places that look the same and are run professionally.
