Because it’s the heating season, potential winter HVAC safety hazards are a timely topic to keep in mind as your furnace keeps you comfortable. Natural gas is the most common heating fuel utilized in our region. Even though gas furnaces have an excellent record for safe operation, it’s a good idea to be aware of potential winter HVAC safety hazards at this time of year.
First things first: The best preventive measure for safe heating begins by scheduling annual furnace maintenance with a qualified HVAC contractor. This not only ensures that your furnace meets energy-efficiency and heating-performance standards; it also involves a list of critical inspections and tests that ensure safe operation for the winter ahead.
Here are two winter HVAC safety hazards that every homeowner should be aware of during the heating season.
- Carbon monoxide. A colorless, odorless gas that is a byproduct of combustion with gas-fired furnaces, carbon monoxide can be dangerous and even deadly if it infiltrates a home. Possible heating-related causes of excess carbon monoxide include a cracked furnace heat exchanger or a defective or obstructed furnace vent. Inadequate airflow due to a clogged air filter can also result in carbon monoxide leakage. Every home should have carbon monoxide detectors on every floor and outside sleeping areas. Test the detectors monthly.
- Obstructed airflow. If the furnace cannot bring in sufficient airflow because the air filter is clogged, the unit may overheat and create a potential fire hazard. In most cases, a furnace temperature sensor will sense the overheated condition and automatically shut down the furnace. However, to be certain, it’s best to prevent the fire potential by replacing the system air filter at least every other month. Obstructed airflow into the furnace can inhibit proper combustion, causing a “flame rollout” where flames extend outside the furnace when it cycles on, potentially igniting a fire.
