    Incorrect installation of Trane furnace

    Hi all,

    Just looking for perspective on how to handle a situation.

    Im a homeowner who purchased a high efficiency (says 97% on the furnace) Trane furnace in 2014. Last couple years, my furnace was struggling to light due to lack of air intake. Which I paid to address a couple times in the last few years.

    The company that originally installed my unit (and serviced the last 5 years) was acquired by another company recently. Long story short, the new acquiring company came out to address the issue (their first time) and told me the unit was incorrectly installed from the beginning.

    The diagnosis is that a 3 termination kit was used outside where the intake and exhaust terminate, while my unit is built with 2 PVC pipes. This created a situation where the exhaust was being sucked back in through the intake, and choking the unit. In addition, rust has formed on the burners and need to be replaced.

    The company recommends installing the proper 2 kit and replacing the burners.

    Im concerned this undiagnosed issue over the last 5 years may have shortened my furnaces lifespan.

    My questions for the forum is if you were in my shoes, would you feel satisfied with the remediation? What else would you want inspected? Would you request a brand new furnace given the situation? Anything else?

    Thanks for the advice greatly appreciate your time!

    The venting requirements are pretty straight forward in the manual. Do a search for and get a copy.

    I would still get a second opinion, the new tech may be a salesman!

    The remediation should resolve the issue of any further re-ingestion as long as the "fix" takes into account any other reason this might have been happening. There are also specifications and good practices that want the exhaust exiting the home in an area that won't be subjected to swirling wind patterns and snow drifts.

    A through clean and service performed on the furnace should identify any thing else that might need attention.

    As far as a new furnace I don't think it's really warranted because the burners are rusted.
    Use the biggest hammer you like, pounding a square peg into a round hole does not equal a proper fit.

    It is common for a furnace to require 3" pipes but have 2" openings. Redo the termination so the exhaust isn't picked up by the intake.

    We must have the furnace model number to know if 2” or 3” pipes are needed. Please provide the model number. Some pictures of the installation would be helpful.

    And how long the venting is.

    What type of termination is on the outside. I have used 3" terminations on 2" pipe for years and never had a problem. IN fact up till the last few years that is all the distributor carried. I just put a reducing bushing into the termination to fill the space and have never had a recirculation problem with the BAYVENT 200 (looks like a oval plate with a hole with bars across it towards one side).
