After months of trying to find someone to install my furnace/air conditioning unit (I literally had 6-7 local companies set an appointment AND NOT SHOW UP!!! and several others never give me an estimate or return follow up phone calls), my realtor recommended Tony & Jeff. I can't say how pleased I am that 1) they showed up quickly and on time, 2) didn't make me wait weeks for an estimate, 3) were thorough and knowledgeable about their work, and 4) finished quickly. I would not recommend ANYONE ELSE in Grant County. They just installed my system so it's too early to see if any problems arise, but if any do, I'm sure I.G.I.T. will put it right. Highly recommend :)
