I have a Generac Generator installed by Alternate Power Solutions in W. Palm Beach, Florida.  I am very pleased with the whole house generator and also had one installed at my country club.  The service contract through Alternate Power Solutions is excellent.  They are available 24/7, reasonably priced and dependable.  When a hurricane is a threat they make sure I am up and running and handle customers even if they need to work at night or weekends.
