You saved a family in radcliff Kentucky today! Heard this video a week ago. My mom got a co detector. Today, it went off and she went buy another and batteries to be sure- kept babies out house. It was 200ppm. Unit 40 yrs old. Her landlord just did not know. The exchanger rusted holes and the timing was truly life saving. Fire department airing out their trailer. I thank you so much. My boyfriend is HVAC but doesn’t see many residentials. We just talked about this and how you felt people need to talk about it. I had never thought about it and it’s just amazing how caring this message is. We did research on sudden deaths and you are filling a complex need for people to just understand call someone who knows this for a living to keep you safe. Many people can run things until they don’t run and not think or remember to get a fall inspection is so simple. Thank you! 3 babies we can hug with confidence tonight because we heard you in time. Thank you for thinking of what we needed to hear! Thank you!

Another 33 year HVAC professional here. I have a very dim view of home inspectors. They are a pro in whatever they did before becoming an inspector. Everything else now they’re looking at from 30,000 feet. I wish I had a nickel for every time a homeowner said, through tears, “the home inspector said….” However I found you, and your video, accurate, informative and helpful. It is is my professional opinion that whether it’s a roof, foundation or HVAC system, only a pro in those areas has a pros eyes. Kudos to you for a great video.

I get your concern, but it is not realistic to send a licensed roofer, electrician, plumber, HVAC and foundation guy out to every possible home sale for an inspection. A well trained and conscientious home inspector is likely the general public's best bet at getting someone to catch the most egregious deficiencies in the most expensive purchase of their life. The HI training I am going thru now also repeatedly emphasizes when things look shady or suspect, you absolutely tell the client to get that professional out there for the discipline in question to do a thorough check. Besides all that, the tech from all those disciplines that actually shows up to the house is often ( if not mostly ) NOT the guy the holds the real knowledge and license for the company.

@@davec6016 I might add that there are a few areas that a pro in that area might be a good idea. My experience, like HVAC techs honestly, is that competency, can be hit and miss. So, while I agree with your assessment, because it can cost a fortune to hire specialists, your comment assumes 'a well trained and conscientious home inspector' is a given. IME, it's not. If a home inspector represents himself as all things home, it's a red flag. Home inspectors---done well---are excellent generalists. If their trained eyes see something, they should always recommend a specialist in that discipline. On that we agree.

I'm not an HVAC tech, rather I'm an engineer in another discipline. I thought some might be interested to know the following: The largest combustion products produced when burning natural gas (primarily methane) is CO2 (carbon dioxide) and water. Burning 100,000 BTU worth of natural gas produces about 1.25 gallons (almost 10.5 pounds) of water and 1.7 pounds of CO2. It's the CO2 produced that is of concern related to CO (carbon monoxide). If the natural gas flame is starved for oxygen, less of the carbon content of the methane is transformed into CO2 and more of that carbon is transformed into CO.

13 years with a now 25 year old furnace and never had serviced. What I've learned. The igniter typically fails when it's 10 degrees out due carbon buildup on the flame sensor from turning on and off constantly. To prevent this I take some 320 or 440 grit sandpaper and give the flame sensor a yearly light sanding before it gets really cold and I now don't have to worry about the igniter dying, but I do have a spare. I just replaced the draft inducer blower which wasn't too hard to do or diagnose when it starts making the bearing noise. I do have to give it a good cleaning, but will ride it as long as the flame is blue and it still looks good. Up in New England so it gets a good workout in the winter. Rheem Criterion II. Now that I realize it's close to the end of it's recommended life expectancy I'll keep a closer eye on it.

And to support the video. Remember the average home owner will likely NOT be able to evaluate furnace performance. The pros that are up to date do an exhaust or stack gas analysis that consists of the % of CO2 and the stack temp. Certain temp level not below or too much above must be achieved to assure the furnace is BURNING and VENTING the gas efficiently. The stack temp and draft testing using a draft meter along with a combustion analyzer will help assure the unit is healthy working safely and effectively. Your tech needs to be a pro, trained in gas furnace operations, know how to visually evaluate and then do the combustion gas analysis and draft. The adjustments here if needed will involve the air mixture to the burner, the draft restriction (if a damper is used) and possibly even gas pressure. It's not rocket science but it does require a Pro!

My company performs combustion analysis on every furnace we walk up on. The main issue I’ve found with premature heat exchanger failure is oversized furnace and/or inadequate duct system running too high static pressure. Very common to see furnaces rated at .5” w.c. running .8, .9 and sometimes over 1.00”. Even worse on 90+% furnaces that require 150 cfm per 10,000 btu. On top of that you have customers closing too many vents and using restrictive filters or not replacing filters frequently enough.

Thank you for this very important video. Years ago when we purchased our first house, we did have a house inspection and nothing major showed up. When the winter came we bought a carbon monoxide detector. In fact our friend asked us to buy one for her also. We bought it, plugged it in and it started to scream. We thought oh, this one must be defective, and plugged the second one in to the same result. Called the gas company and they tagged the furnace for carbon monoxide. Funny thing is a couple of days before we bought the detectors, both my wife and I were getting headaches. We consider ourselves lucky and have never been without a carbon monoxide detector since.

Hvac guy here. I'm in the South on natural gas. On the topic of CO in general, I see roofers pull out vents and never reconnect them in the attic, bad vent placement and materials, not double walled. I see it in winterized homes that are brought back online when h2o heater fills back up, sits down and breaks the vent collar at top of the unit. Lots of older hvac units that need adjustments. Big trend here when we had tax rebates to over insulate houses. Locks up all the combustible air. Great video. Those free biannual checks to look over your equipment may be opportunities to upsell by bad companies, but if the tech is good, they will hopefully catch this. Also, make sure your filters aren'tblocked up. Thanks for the video.

Excellent presentation, I remember in the early 70's the furnace in our house had to be replaced. My mother said the "coils" had cracked, which I believe where the heat exchange mentioned in the video. While I do not remember the make of the old furnace, it was a big green monster of sorts. The new one was a General Electric. The one drawback was having to remove the bottom cover to change the filter. Unlike the old one, which the duct work it dropped down between the in-let duct upstairs and the furnace blower.

The first half explaining the error situation is good and thorough. The second half regarding the CO detector is totally correct. But I'm not sure about the advice regarding routine annual check & maintenance by a professional company. What can that accomplish except throwing away hundreds of dollars? My Carrier high efficiency furnace just got a flame rollout error and it turned out the heat exchange had been badly rusted and blocked. The flame hasn't been that blue or straight for a couple of years. But there was not anything a maintenance guy could really do about it. The only solution is to change the whole heat exchange once the error code finally appears. It's basically a design flaw in the furnace itself. You can't do anything about it unless you spend thousands to change the heat exchange (a credit to Carrier - 1st time it’s free for they know it’s their design issue) every few years or change the whole furnace.

As a retired HVAC tech I would like to say this is an excellent video. Modern furnaces have exhaust gas motors which forcefully exhaust combustion gases out of the building. They generally have either a pressure switch or a Hall effect sensor ( to monitor for correct rpm) so a clogged flue will shut down the unit. The older style naturally vented furnaces( non powered exhaust) were the real killers when the flue became blocked. When this happened in older furnaces, the combustion gasses had nowhere to go but back inside the building and because it had no incoming draft of fresh air to support complete combustion the combustion products would contain high levels of carbon monoxide and alot of these older furnaces did not have all the redundant safety switches to detect this. In my long career I only found one furnace malfunctioning badly, and it was a unit that had a forced combustion fan running at less than half speed and the Hall effect sensor failed. This was a unit for a classrooom full of kids but fortunatley all the exhaust gasses were vented to the roof.

It would be kind of hard to do without explaining it in person. Most "old style" furnaces are not even around anymore because like all appliances, they have a lifespan and wear out. The natural draft furnaces (old style) to the best of my knowledge, have not been manufactured for at least 30 years. They were really basic, generally had a standing pilot with a thermocouple and no combustion motor to forcibly drive the exhaust gases out and usually had just one safety limit, the high temperature limit switch. Look at some KZbin videos for more info or, if you live in certain parts of the U.S., the Gas company can inspect you furnace for free and answer all your questions.

@@yurydolinskyNo it's not impossible at all. A hot air furnace would technically run with no heat exchanger at all. The burner doesn't know what's going on. The safety on these is the flame sensor, which is the thing this dumbass mistook for the roll out switch. The only other safety is the proving switch on the power venter that closes when the fan comes up to speed to ensure sufficient draft. If those two conditions are satisfied, the burner will run when the thermostat calls, regardless of the condition of the heat exchanger.

High pressure goes to low pressure. So the air from the blower gets pushed into the heat exchanger, not the other way around. Only way CO would get into the home is if the inducer fan fails or the chimney is clogged. In this case the pressure switch would keep the gas valve from opening. And like you said, roll out switches protect the building and occupants too. Cracked heat exchangers cause lower efficiency. Cracked heat exchanger diagnostics are probably the best way to rip people off.

Agree 100% on getting a pro to check. IMHO, this is one area that is not a DYI job. Hire an experienced HVAC technician or company and (I) opt for an annual service contract with a spring and fall full inspection to make sure heating and air conditioning are working properly. That includes full system mechanical inspection & operation, fuel leak detection (natural gas in my case), pressure testing (airflow operation in and out of the unit - how well it is delivering heat/cold air) and venting operation that is critical to make sure there is no carbon monoxide leaking (especially important to high-efficiency systems). Those tests require special equipment that any average homeowner does not, nor has the experience to use.

I am a 50 yr AC tech and HVAC business owner. You're video was right on. Just 2 points I'd like to make: At 3:40 your speaking of a "roll out sensor" but you're pointing to the flame sensor; the roll out sensor is on the plate above where the pointer is. One more thing, the plate is there so that if any part of the furnace (left or right of the roll-out sensor) rolls out, that one firebox sensor will trigger a lockout. Lastly, the "Roll-out" condition you describe @3:05 most often occurs when there is a cracked or rusted-through heat exchanger. Dirty and plugged systems can also cause this but a failed heat exchanger is more often the diagnosis. Thanks for the video it was very informative.

Hello, My furnace was installed in 1961. I remember when the house was being built. It's an old Lenox with the gas jets made of cast iron. And yes over the course of the last 30 years, i,ve literally taken the furnace apart. Taking out that heat exchanger and shinning a light down each of the sections of heat exchanger for blow holes and or corroded spots. To this date none where found. The three gas jets where taken out and with my garage shop air I blasted those gas jets clean. Even like flausing teath , took some size # 0.023 welding wire and flaused those gas jets. Cleaned also the two limit switches. Made sure there functions work by temporary disconnecting blower fan motor to make sure they would cut out with excess ambient heat. Made sure that blower motor impeller would have required lubrication and belt would be inspected for cracked etc. Plus the seasonal change out of any and all filters. And yes above all, I took out the old fireomatic that is installed above the furnace directly above the flu pipe with a heat/ smoke / carbon monoxide detector, with a reverse acting relay that when it goes into alarm, it also shuts down the furnace as well as the rest of my house attic ventilator gets shut down as well as to not create a draft to accelerate a fire. Old furnaces are not fuel efficient, but they can last along time to this very day keeping me warm, if proper maintenance is performed. And yes, it is an old pilot burning gas valve. And yes, i,ve cleaned out connecting tube's of dirt and made sure thermocouple is still looping the circuit for proper ignitions. My skill sets are derived from working with burner technicians over the years. I,ve wired many such appliances. I currently work at a passenger rail facility in which we have many suspension gas heaters heating up the train shed. Every Oct we do inspections. The units themselves don,t last long due to the corrosive environments of what our train sets bring in.

About 2 years ago,I saw a YT video made by what appeared to be a mom who was cold and desperate. Apparently, she started poking around the inside of the furnace looking for the reason why it wouldn’t turn on. Well, she found the cause, she pushed the “magic button” and all of a sudden, the heat comes on. She was so proud of her success that she felt a need to share it with everyone. Guess what she found ……….. the FLAME ROLLOUT SENSOR!!! In her video, she made no mention of what it was or any mention of getting the unit serviced, just PUSH THAT MAGIC BUTTON. I hope and pray that her and her family are alive today.🙏 This video just gave me a profound enlightenment that when we service a furnace ( either professionally or as a DIY’er), we are responsible for the lives of the people who live there !!

If the majority of the flame is orange, you see roll out or you see yellow then you have a problem.

We manufactured and installed all types of sheet metal from flashings, gutters, chimney sweeping, roof repairs, gutters rain drains and downspouts. Also from water heaters and central heating systems, wall heaters and space heaters. What is very much of a concern is when others replace let’s say a furnace they never go up to the roof and check if it’s properly vented. I had one instance where an old gravity heater was rusted at the unit because a handyman put a bucket over the roof flashing that the chimney had blown off. Also roofers install a standard bonnet top for type B venting instead of a proper metal bestos termination duct with a high wind termination cap and storm collar.

Good info but a lot of people will be turned off by "you cant do this yourself call a professional." Well I was told the same thing when I replaced a single three ton heat pump unit with two two ton units splitting up the floor. I had a couple of HVAC contractors tell me I would go to jail if anyone found out I did it. Total price tag was about $2000 for both not to mention the $400 I made back from selling an HVAC contractor the old condenser unit. Yes I get it that a lot of people can not do it but making stuff up does not help your case. I found one local contractor that was totally supportive. They said they had a ton of work and were more than happy to just do a service call to check up on my install. Going on 12 years both units have only needed occasional checkups. Like when the vinyl siding crew moved the unit about six inches to the right and let all the refrigerant out. Or when the $7 cap crapped out randomly. Easy fix. Now one of the unit has a smaller problem involving a combination of a cap or thermostat. Not a giant deal. I can do a lot of trouble shooting for the $5000 I was quoted to just replace one unit! The end lesson is carbon monoxide detectors. The girl I was dating in college insisted one be installed in her apartment prior to moving in. She was woken up several dozen times by the alarm and twice when I was there. Finally the maintance people replaced the furnace. Were the levels high enough to kill us? Dont know but they didnt want to fix it unless they had to.

As a bit of a cost savings side note, some furnace repair companies will allow you to pay for inspections (and or cleaning) in advance at a discount. The service company we use normally charges $120 for an inspection and cleaning but we were able to pay for 5 years of service in advance at a price of only $75 per year for inspection and cleaning. We have it done every year anyway and we like the service company we use so it was well worth paying up front to get a discount. Plus we get priority scheduling when it gets busy as the season starts.

You make good points, but I would like to vouch for the safety of these modern furnaces a bit. Hypothetically you could have a poorly burning, high co level flame situation alongside a large crack in the heat exchanger, but you have to remember that the flue gasses are being drawn through the exchanger, meaning it is under negative pressure, while the surrounding air is pressurized by the air blower. This will drive extra air into the heat exchanger, confirmed by higher than normal oxygen levels in the combustion analysis readings. You would still need some other mechanism to get co into the living space. I've had service calls where I've measured +10,000 ppm of CO in the exhaust, and during the off cycle I could read 1 ppm around the seams of the furnace cabinet, I assume as residual CO that did not get expelled during the post purge. 0 ppm in the actual air stream of the duct. Long story short, these are extremely safe units with multiple safeties within, and add several CO detectors in the house and the dangers are effectively 0

I expect the backdrafting mentioned in this video requires two conditions. First is insufficient [or no] make up air brought to the burner. Second is the air handler vs. building scenario. If the home is "tight" that leaves conflicting forces: should they become balanced, or the air handler overwhelms the bulk of exhaust trying to escape, that's a major problem. Nature find its ways... rats/mice, mud daubers in the wrong place might overwhelm what was initially a workable install that passed inspection.

One thing you also need to consider is a heat exchanger with holes cannot be guaranteed to be lower pressure to the fresh air side of the furnace in all places … the absence of any wall due to corrosion means it’s impossible for their to be a pressure difference between inside and outside the exchanger.

Some people called because they noticed a funny smell around the furnace, they noticed a yellowish glow by the furnace. They didn't have a CO detector. I would ask them what their life was worth? Is it worth $30 to $50 for a detector? They usually didn't know what to say.

That's why I like my boiler heat. I have a detector just above the furnace in the basement even and one 7 feet above with the furnace and 3.5 feet away from it. That way I can detect any CO2 rapidly building up in the basement. I also have a detector at the lowest outlet in every room (before it can reach the height of the bed where your sleeping and you wouldn't notice the signs/symptoms of CO2, poisoning whole sleeping when most deaths occur from CO2 poisoning) in my home and smoke detector 8 inches from the ceiling since smoke rises and CO2 sinks. I also have one at the base of my basement steps high as it can go and one at the top of the stairs where smoke would bellow around the corner from the natural draft a basement has from lower to higher. People call me crazy for so many, but it's worth keeping my children and grandchildren alive when staying over. Something to think about....

Video calls it a roll out sensor then points to spark igniter electrode or a flame sensor,, some furnaces combine both..this device teels the control board "I indeed do have a lit burner) the twin two wire switches with the black and red wires "above" the burners with the red plunger in the middle are the roll out sensors,, they detect excess heat from a flame roll out where its not supposed to be and trip killing the power to the gas valve .. this was pointed out below as well. always call a gas technician to inspect the furnace for safety issues if you find one tripped, they do not trip without a reason..

Great job! As a former volunteer firefighter I am thankful that you got the word about the dangers of CO. As an electronic engineer I think the arrow in your video was pointing to the spark ignition/conductivity flame sensor... on the surface above I saw 2 thermodisc heat switches. I believe those are primary roll-out protection. But to your credit a partially blocked flue can cause a minor roll-out that would not trip the thermal shutdown, but WOULD produce CO in the living area. Side note: No hot surface ignitor was shown in the video. So I'm guessing the flame conduction sensor and the spark ignition electrode are now combined into One? Clever cost saving for Mfrs?

I was getting bad headaches and fogginess upon waking. Suspected furnace. It would 'pop' sometimes and I noticed fumes when entering apt. when furnace had been running. Landlord's maintenance dude said it was fine. I called Power company. Their inspector found cracks in plenum directly above burn chamber and red tagged the furnace. Said the whole unit was too old and unsafe. Renters should get carbon monoxide detectors if they don't already have them.

Were you able to isolate the root cause? There are a lot of environmental changes when moving to a new house, especially if it's in another state. You can also check for radon, water quality, air quality (especially if near an Interstate or industrial area). A basic radon test is pretty cheap. Sometimes a good furnace filter & HEPA filter can help if it's air pollution or allergy related.

Me and my girlfriend’s condo we were living in for 4 years, we found out after we sold it that during the homeinspection, our furnace actually had about a 4” gap between the exhaust pipe and furnace that the previous inspectors we paid for before purchasing the condo apparently missed. It was spitting out carbon monoxide every time in use, thankfully it was next to a duct/vent and it was being thrown up into the attic the entire time. Still crazy though

Very well done video sir! I have worked in the HVAC field for almost 20 years. Both in service and install. Your information is on point. It cannot be stressed enough how much danger these seemingly small malfunctions pose to homeowners and their families. As well as the importance of having your system evaluated seasonally by a professional. Thank you for putting this out there. I really like that you branch out into other trades as well as carpentry. Keep up the good work.

This video appeared in my KZbin feed because of some searches I'd done due to a carbon monoxide near-miss two days ago. I inherited my mom's house after her passing two years ago but had not spent much time there during cold weather. Just stayed there this past week and woke up one night with severe vertigo that has lasted several days now. Called a technician to check out the downstairs unit and sure enough, the heat exchanger was rusted through in several spots. I thought I had Covid with being out of breath and tired for days, but no...it was carbon monoxide poisoning. I just purchased six CO detectors and will put them all over the house for the future. Also will not stay another cold night there until both units are serviced and checked out. Don't ever want to repeat this. It could have ended much worse, and is certainly not something to dismiss or be cavalier about. Silent killer. You won't have a clue.

My son and I both got carbon monoxide poisoning years ago from our furnace, it almost killed my son because he slept on the top bunk next to the vent, it took about 3 days before we figured out what was happening, we thought we had the flu, until I got a call to get out of the house, I crawled to the door and opened it up and it was like a flash and I was able to stand up and get my son and carry him out, the fire department came in and they where getting sick from the air, boy oh boy never saw our landlord move so fast to fix anything in that house the way he moved that day and he even came to the hospital to check on us, lesson learned our unit is checked yearly and we have detectors now.
