We purchased a new house about 7 months ago, we happened to notice while we were in the basement that the furnace (a Coleman) had a lot of rust on the front face of the unit. We contacted our builder and they placed a work order in for us (which was great). When Prima arrived they looked at the furnace and advised us it was surface rust, they further advised that there is not much they could do, because the rust was surface rust they indicated that the furnace was installed dry and that they builder may not have kept the basement as dry as it should be, they offered to sand off the rust on the furnace and spray paint the area they sanded. We're not too impressed with this company's lack of explanation, because looking at the rust it seemed that there was a leak at some point....avoid this company when possible....but at least they tried to do something...
