Complaint Review: ARS Rescue Rooter

I was looking at hybrid water heaters at a big box store.  I was asked by a guy with a clipboard if I wanted a free estimate on having a hybrid water heater installed.  I agreed.  A rep from ARS Rescue Rooter came to my house and presented me with a estimate of $3900.00 to install a hybrid water heater.  I laughed and invited him to leave immediately.  he then tried to charge me for the estimate.  Good luck with that!!  I called a friend who does handy work.  he installed the hybrid water heater for $350 parts and labor.  How many people deos this company ripoff?  I was amazed.
