How much carbon monoxide is normal

[ponytug]

Yes, zero is the right number.

Cracks can go from small to large quickly. It doesn't take long to replace a wall furnace, ( a few hours) though there are better efficiency alternatives.

Good luck, and thanks for not ignoring the CO levels.

All the best,

Peter

I have never run it beyond the test so it looks like I'll be getting a new furnace soon.

If they replace the gas furnace, what should be included is a new CO2 detector as well. If there ever is a problem with CO2 in a house and it makes news, the last thing a HVAC contractor wants to do is be put under a spotlight to see if they made any assumptions that could of potentially cost someone their life.

Not certain if this made national news, but it was a 3 ring circus because the state screwed up as well...

I'ts now code in NC for residential applicaitons for a CO2 detector to be in the hallway for each bedroom unless a room has a fuel burning device, then the detector goes in the room. It's always a good idea to have a least a couple for each floor. Generally people buy one, put it in a bedroom where they sleep. Only problem is depending on where the build up of CO2 is, you could be walking into a dangerous level and not even know it because the only alarm installed hasn't detected the build up yet.

CO2 posioning doesn't happen that ofter, but when it does, it's a reminder of why detectors are needed.

CO detectors have been required in California for years as well as smoke in each bedroom and one additional on each level.

As homes become tighter indoor air issues are more pronounced...

That said going to sealed detectors with 10 year batteries is a good thing...so many times I inspected rentals only to find batteries pulled from all detectors.

Recently had my gas forced hot air furnace circa 1983 serviced and the tech ran a carbon monoxide meter on the vent closest to the furnace. We stopped checking after about 30 minutes and PPM was up to 28. He didn't seem too comfortable with that. Just curious, what would you consider safe levels?

getting down to close to zero if it were my home. In the early 1990's we had a gas furnace replaced with a 98% efficient unit.about the only thing out the exhaust (3" plastic) was condensation. The new unit was a smaller btu and ran longer. irculated heat longer and used far less gas. Win Win. From what we saved the furnace paid for itself.

Surprised in the link Sigarms posted at only the $100K settlement. Kid died.

EDIT. I did not read far enough. Separate $12M suit

As I said, the state screwed up as well. That's what the state paid out. I personally knew some of the players in that fiasco. It's amazing how fast the state will cover it's butt when it has a big "uh oh" moment.

It's becoming code for fresh air intake for new homes. Most guys just bypass with using the fart fan in one bathoom and call it day LOL

I'm actually suprised california hasn't gone to requiring ERV's for homes.

I've found the plug in detectors with battery back up work well.

Yes, that is what I have. They do not need to be up high like a smoke detector, CO disperses fairly evenly.

I'm surprised nobody has mentioned the best resource of all. That would be your local fire department/EMS. Call or stop by and they will gladly fill you in on the dangers of CO.

They may even have a program where they will replace your detector for next to nothing.

When California gonna do someting bout all dat outdoor tree & brush burning dey do every year besides send smoke East. Clear violation of CalCARB dat is..
