Combustion Appliance Testing

Combustion appliance testing is a service that helps eliminate any future issues with your gas or oil systems. When you have combustion appliances in your home, they require yearly inspection and maintenance to keep them running efficiently. When this service is completed, it verifies all safety devices are operational and unit heat exchangers are sound. We also cleaned and adjusted pilot light systems during the test to keep them working in top condition.

Why Is It Important?

Combustion appliance testing is important in residential homes because it can help identify potential safety hazards related to carbon monoxide (CO) poisoning. Combustion appliances, such as gas furnaces, water heaters, and stoves, can produce CO if they are not functioning properly or if there is inadequate ventilation. CO is a colorless, odorless gas that can be deadly in high concentrations, and symptoms of CO poisoning can be easily mistaken for other illnesses.

Carbon Monoxide Testing

Measure the amount of carbon monoxide poison in the heating system.

Flue Draft Testing

Ensures proper draft to remove flue gasses from the heating system.

Spillage Testing

Checks if CO or other harmful flue gasses are spilling or entering the home.

Gas Leak Testing

Checks to ensure gas lines are not leaking causing a health & safety issue.
By conducting combustion appliance testing, technicians can measure the levels of CO produced by these appliances and determine whether they are operating safely. If high levels of CO are detected, the technician can recommend repairs or replacement of the appliance to prevent potential health hazards to the residents. This can help ensure the safety of the occupants of the home and provide peace of mind
