I own a condo in Rolling Meadows, Illinois. It has a Triad Model TFS300 ductless combo heating/ac unit. The unit was installed in the 1970s. The blower motor bearings are starting to wear out and the motor is making noise. I have had three hvac contractors out to remove the blower motor and find a replacement. All three contractors don't want to work on it. They also don't want to quote me a replacement unit. The last contractor said, "I don't want to touch that unit with a 10 foot pole" Is there anyone out there who can work on this unit, replace the blower motor and/or quote me on a replacement unit.? Or recommend anyone who can?
