Enercare Home Services

I currently rent my AC unit from Enercare and have been trying to get the unit serviced for weeks. They take so long to schedule a service technician - 2 weeks or more - and the unit has not been working for a month now. Still paying a rental fee, though. Also, their customer service department is unorganized and offers so little support or information. If I was ever asked to provide a recommendation, it would not be a positive one. Right now I'm trying to understand how renting is a benefit if it takes them over a month to service their equipment.
