Combustion Safety Check

Fuel-burning systems such as furnaces, boilers, and water heaters are essential - but when combustion, venting, or airflow conditions aren’t right, they can introduce serious and often invisible safety risks, including carbon monoxide (CO) exposure.

Our Combustion Safety Check (CSC) is a focused safety screening that includes real-time carbon monoxide measurements taken near fuel-burning appliances and within the home, along with a visual review of combustion-related components and venting conditions. Because CO is colorless and odorless, these risks frequently go undetected without direct monitoring.

This add-on service provides meaningful safety insight and documentation, helping homeowners and buyers identify potential red flags and better understand when further evaluation by a licensed professional may be warranted. The CSC is a limited, non-invasive screening intended to enhance safety awareness - it is not a full diagnostic or performance test.


As part of the Combustion Safety Check, our inspectors will perform:

  • Spot ambient carbon monoxide measurements near fuel-burning appliances during operation and in representative living areas of the home

  • Visual review for common combustion-related concerns, such as signs of back-drafting or ventilation issues

  • Observation and documentation of carbon monoxide detector presence in recommended locations at the time of inspection

Fuel-burning sources may include furnaces, boilers, water heaters, fireplaces, gas stoves or ovens, and attached garages, when present and safely accessible.

Carbon monoxide (CO) is an invisible, odorless gas that can cause serious illness or death if undetected. Our Combustion Safety Check helps protect your household - especially in homes with older systems or limited ventilation.
