I have an old house and vapors are coming up registers! New heat/air cond. system.I have had vents cleaned twice. same thing happened with old furnace! Is it worth the cost to replace vent system when we may sell home in a year or so! And they may tear it down for the property? Is it really expensive! Thank you everyone!
Yes, definitely have it replaced, you need to do this for your own health #1. and also if you sell it , its going to have to be replaced anyway. you did mention that they might tear it down , but you can't play with your health, its totally worth it at any price.
Sorry I am of no help but my goodness it doesn't seem like that long since you had problems with that furnace. Hope you get some good advice.
You should have it inspected anyway for a cracked heat exchanger that can kill everyone in the house. Your utility company (PG E) does it for free. It is not cheap to replace one, but you will have to if you are selling your house. It is something you should never ignore.
