Where Should I Install CO Monitors?

The CO (Carbon Monoxide) detectors are among the essential safety devices in every home. CO monitors detect the presence of CO in the air and can sound an alarm if excessive levels are found. If you’re reading this, I assume you already know what COs are and why you need them.

While CO monitors themselves are relatively easy and inexpensive to install and configure, you need to determine where you should position them in your home and how to connect them to your existing HVAC system. In this article, we will discuss the various places you can position CO monitors and how to choose the right one for your needs and location.


One of the first places you should install a CO monitor is in your basement. Basements are a natural habitat for rodents such as mice and rats, which can harbor the bacteria that causes CO poisoning. It’s also the place where you store a lot of your valuables, so it’s a frequent target for burglars. If you have a large basement, it’s a safe bet that you have a lot of space for equipment, so consider expanding your search to other parts of the house.

You should also check for CO detectors that have been built into the electrical system, since most homes have wiring that was laid down during the construction process. These detectors are usually hidden behind panels and are very hard to locate if you don’t know where to look. They can also be a bit pricy, so if you can find a working manual for your HVAC system online, it might be worth your time to take a look at how to properly install one.


If your garage is adjacent to your house, it’s a popular place for rodents to build their nests, so having CO monitors there won’t be a bad idea. Like the basement, the garage is also a place where you store a lot of your valuables, which means it’s a frequent target for burglars. You can also position the monitors above ground in a place where they’ll be visible to passing people or animals and give you an early warning of intruders. This is often the case for garages attached to homes whose inhabitants don’t want prowlers seeing their expensive cars inside.

You also need to think about where you’ll position the CO monitors in terms of the size of the area you have and whether you’ll have access to electricity or natural gas if you decide to go this route. Smaller garages often don’t have the room for an air pump or other equipment necessary to get the air circulating, which means you’ll need to install an in-floor air pump or look for other solutions. If you have a lot of space, you can always install an air pump.


The attic is another place you should inspect for CO monitors. This is where a lot of the wiring is located, which means it’s a perfect place for an electrical short or other types of damage that could lead to an accidental fire. If you have a lot of space up there, you can fit a lot of heat generating equipment, which means further increasing the chances of an electrical fire. This is why the CO monitors are usually positioned on the ground near the exits in case of such a disaster.

There are also a lot of pests that live in attics, including mice, rats, and sometimes even bats. These are all creatures that can carry nasty diseases, so having CO monitors up there will be beneficial in case one of them bites someone while they’re asleep or invades the home without your knowledge.

On Roof

If you live in a warmer climate, you can always install the CO monitors on the roof. This is a great place for them because it’s always warm up there, so there’s no danger of freezing, and the air is fresh and moves around a lot, which makes it ideal for animals and plants. On the other hand, if you live in a cold climate, it’s best to keep the CO monitors off of the roof and buried in the ground where they’ll stay at the right temperature.

No matter where you decide to mount your CO monitors, make sure that the area is well-ventilated and has enough space for you to move around without any trouble. Remember: you’re looking for the safest place you can find for your family and belongings. Make sure whoever you hire understands this and takes it seriously.
