During a combustion appliance zone test, Comfort by Kodiak identified that our furnace had been "back-drafting" poisonous gasses, including carbon monoxide, into the supply ductwork from our furnace and throughout our home since the original installation.  They replaced it with a new 93% efficient model, sealed the ductwork leaks, and added a fresh air ventilation system. It was a first-class installation, including the mechanical room remodeling. I have confidently recommended them to business associates, family and friends.
