I live in an 8-year old townhouse and had a routine (my first) maintenance visit. The supposedly reputable plumbing technician seemed very thorough, but I wanted to be sure I'm not being taken for a ride. He put on a rubber glove, felt the blower motor & when he pulled his hand back, it was full of grease. He says this means it needs to be replaced. Is this true? I have had no problems whatsoever with my heat or A/C, but since this is also a year-round piece of equipment, I thought I'd check before telling them to replace it. My furnace is a Ruud Silhouette II gas furnace. Thanks for any help you can provide.
