I have just had a Carrier Infinity 96 installed by a heating sub-contractor in Portland Oregon as part of a basement remodel.
They have made a real mess of the job. The first mistake they made was sealing the ducting with Vulcum caulk which stunk the whole house out with a toxic cocktail. I have spoken with other heating contractors who have told me this was a big mistake.
Our general contractor had the heating sub-contractor tear out all the ducting and replace it with new ducting with taped seems. The Vulcum smell has gone away but there is still a burnt plastic/chemical smell that comes from the ducting vents when the heat is on. Is this normal? Is this a new furnace smell that should dissappear after a week or so?
This whole experience has been very stressful and we just want to make sure the installation is now correct. My wife is pregnant and the last thing we need is toxic air in the heating ducts. I'm considerring having an independent heating contractor do an inspection.
Any comments/thoughts will be much appreciated.
