Combustion appliances or mechanical systems, including fireplaces, gas stoves and gas heating systems, produce by-products that need to be removed using a system of vents or flues known as an exhaust system.
To function properly, exhaust systems must be free of holes, cracks or rust.
Exhaust systems should be installed so combustion products are carried out of the house before cooling and condensation occurs.
High air pressure outside the house, low air pressure inside the house or improper appliance operation can sometimes impact the effectiveness of vent systems.
An NPI professional will evaluate the condition of the heating system, the location of master switches, functionality, the type of energy source used and the method of conducting heat throughout the home or business.
