National Comfort Institute

This certification was established in 1992. Carbon monoxide is the leading cause of poisonings in the US. Even if you have a UL listed monitoring device consider having your home evaluated. The majority of monitors don’t alarm until CO levels reach 70PPM , OSHA and
WHO guidelines warn that levels of 15-35PPM can be unsafe. There are many sources other than your heater that can contribute to the problem such as your water heater, gas or electric range/oven, gas logs, heaters, boilers or an attached garage. An NCI certified technician will be able to test your heating equipment and other combustion appliances and diagnose potential CO exposure. Find a certified CO Analyst today.
