Technician from AA Service and Repair North Florida AC came to our house for central air conditioning "Periodic Maintenance/Seasonal Tune Up" and did nothing! He told us our a/c, that is running fine needed replacement for $4600 at $80/month! HE DID NOTHING...Did not clean or service the unit at all! He collected the $39 "service call" fee and did not take CHECKS! Now we understand why -- He took out a DEBIT card device and had cash instantly! We want our money back and want to warn others....Saw that they have done this sort of thing before to other customers...BUYER BEWARD
