Carbon Monoxide Alarm Problem
I' m really not sure this is the forum for this but I know there are plenty of home builders on this forum who have had experience installing alarm systems and could direct me to the right kind of expert for advice/ service. You've been patient with my dumb questions before so I hope you can indulge me one more time.
Our house is two years old and we have been having problems with our carbon monoxide alarm going off. We have geothermal heating and only use gas for cooking and our fp. The first time it happened we did the prudent thing and called 911 and left the house. We also opened the up windows and doors on the way out. A battalion of emergency responders showed up and after two hours were not able to find any indication of elevated co levels. They suggested we might be experiencing a false positive. These are hardwired units with battery back up. We replaced all the batteries and called it good.
That was two weeks ago and since then we have had the alarm go off two more times. The second time we threw open a few windows ( just in case) and took one of the units outside to see if it continued to go off. It did for awhile but eventually stopped.
The third time was last night during the night and in this case I had done some thing really stupid. I left some thing on the stove on a very low simmer.
So ...I know I have a problem or multiple problems. I'm just not sure what it is or who I should be working with.
Do I have a faulty alarm that some times gives a false positive and coincidentally was triggered appropriately last night?
Has the alarm been working all along and the problem might be a problem with the range. I don't cook a lot so I typically don't have a burner on for any length of time. However, I had been using the range more then normal in each incident where the alarm was triggered.
Is it possible that a house could be too energy efficient and would allow low amounts of co to accumulate?
From what I've read, both the alarm system and the range should be new enough that they should still be in good working condition. I need to fix something ( including my cooking habits) but I would like to hone in on the most likely source of the problem before I start calling in service people. If the range is the problem than why would the technician who came to our house the first night not have detected elevated levels?
The fire department told us that every time the alarm goes off we should call 911 to be on the safe side but the service guy from the utility company didn't seem quite as concerned. I just know that the alarm will drive us crazy if we don't fix something and I can't see having the fire department come to my house every time the alarm goes off. I don't want to be the boy the cries wolf all the time.
If anyone has any experience with hard wired units such as ours I sure would appreciate your thoughts.
