I bought my 60 year old house 3 years ago and before I moved in I had the electrical "updated." The electrician pulled the existing fuse box supporting the electricity to the house and the breaker box supporting the central HVAC system and combined them into one larger breaker box with a 200 amp capacity. He also worked in the attic for about a day and said that he was correcting a possible problem. But since I don't know anything about electrical work, I didn't ask what that problem was. I recently replaced the old central heat/air with a new unit and the company who installed the new unit has recommended I add additional insulation in the attic. But in doing some research on insulation, I have found that it is unsafe to add additional insulation with knob and tube wiring so I looked in the attic and it appears that I still have knob and tube wiring. Is it even possible to have knob & tube wiring with a recently installed breaker box? Is it a major cost to have the knob & tube wiring replaced? Any information that anyone can give me is greatly appreciated!

Just because you had your sertvice equipment upgraded does not mean ther K&T wiring has been eleiminated.

First off, have an electrician (or call the previous one) come by and determine if the wiring is still in use. Many electricians do not remove the old wiring when it has been abandoned..

If the wiring is still in use, ask for a quote to have it replaced, get prices from several contractors. Since prices vary considerably from one area to another, on line cost estimates are usually useless.

If it is still in use, and depending how the K&T is run, you could add a good bit of insulation as long as the K&T is not covered over. This would be a tempoarary measure until you can eliminate the K&T wiring.
