They Should Have Been Dead

By
Home Inspector with Complete Home Inspections, Inc. TN Lic#050

    I am always leery of some of the older forced-air gas package units as there are some that are notorious for having cracked heat exchangers. According to the Fuel Gas Codes, if a heat exchanger is cracked, it must be replaced or a new furnace has to be installed. This is a requirement, not an option. If a company considers the heating equipment to present an imminent danger to the occupants, they might disable it, red tag the unit or turn the gas off but this policy varies from company to company. There are some companies that are scamming homeowners by telling them that the heat exchanger is cracked. This is a blog of another color tho.
    On a recent inspection, an HVAC contractor that I know was servicing a suspect package unit. Normally, on their inspection, they do not pull the heat exchanger, they look for evidence of cracking or burn-out. In all his years of working on furnaces, he had never seen one this bad. All four tubes were completely blown out and all the safety devices had been bypassed or disabled. By all rights, the occupants of the home should have been dead due to CO poisoning. 
    The average life expectancy of heat exchangers in gas package units is about 10 years. This will vary depending upon the manufacturer and the usage of the unit. Semi-annual tune-ups is a good way to keep your unit working safely.

Sally, there is a difference between a CO detector and a CO monitor. I am amazed that no one died.

I don't know Michael noting that a little Duct tape couldn't cure.  Of course I wouldn't want to live there...

I was called once to inspect a house before the children who inherited it from their recently passed mother put it on the market.  She died in January, over the course of a few months, with an undiagnosed illness beginning in October.  During my inspection I found the back side of the furnace rusted open and holes clearly visible.  It was against the wall and hard to see, but I wanted a look anyway.

Turns out that had they called me in September to do an inspection I might have found that and saved the lady's life.

Her bedroom, and bed, were directly over that furnace.

Nuff said.

Oh, and many combo smoke/CO detectors have been recalled.  The first was System Sensor, recalled by CPSC in February 2015, and then most, if not all, of the other manufacturers voluntarily recalled theirs. 

Watch out for what the Nannies mandate!  In addition to Big Brother, we have Big Nanny.

I don't pretend to understand all this technical stuff about HVAC systems, but this sounded very scary!

Scary looking!  I have run across several cracked heat exchangers in the last several years, including one in the house we were buying last year. The furnace was not working and we negotiated a credit for replacing the furnace before moving in

California mandates CO detectors and smoke detectors, thank goodness.

Regular checkups are important for this reason and to make sure that they units are working at their top efficiency. Our new units are operating just like they should.

Wow!

That is far beyond a cracked heat exchanger, it is good that it is being repaired now before someone does die.
