I had another “larger” company come out and they said I needed a new system for $5,000 plus and that the system was dead. Went to Hamilton and the service technician was very professional, examined the system said that the motor was not working, that the system was old but that the only thing that wasn’t working was the motor. The technician replaced the motor and it has been working ever since. SUGGEST YOU GET HAMILTON OUT TO SERVICE YOUR SYSTEM FIRST BEFORE YOU ARE CONNED INTO BUYING A NEW SYSTEM FOR THOUSANDS MORE.
