,We get physically tired during long days but always do comprehensive furnace check-ups. Why? Because we do it for your safety. We test if the furnace starts up and runs smoothly. Most people don’t realize we spend equal time ensuring the furnace shuts down properly and safely.
During a furnace check-up, it’s essential to ensure that the furnace is operating safely and efficiently. Otherwise your furnace can be a safety and fire hazard. Here are some safety features and components that we check and why we do it.
Furnace check-up list
- Flame Sensor and Burner: The flame sensor or thermocouple is a crucial safety component. If it fails to detect a flame when the burner is on, the furnace should shut down to prevent gas buildup. We ensure the sensor is clean and functioning correctly.
- Gas Valve: Check for any gas leaks or issues with the gas valve. A malfunctioning gas valve can pose a significant safety risk.
- Limit Switch: The limit switch is responsible for turning off the furnace if it gets too hot. A faulty limit switch can cause overheating, which is a safety hazard.
- Pressure Switch: The pressure switch ensures that there is proper airflow. If there’s an issue with the air supply or exhaust, it can shut off the furnace to prevent carbon monoxide buildup.
- Carbon Monoxide (CO) Detector: Many modern commercial furnaces are equipped with CO detectors. We check the CO@ detectors in your home ensuring that it’s operational and it will alert you if it detects high levels of carbon monoxide.
- Venting System: The venting system is inspected for any blockages or damage. Proper venting is essential to prevent the buildup of dangerous gasses like carbon monoxide.
- Air Filters: Clogged air filters can affect the efficiency and safety of the furnace. We check and replace regularly to maintain proper airflow and prevent overheating.
- Electrical Connections: Unfortunately loose or damaged electrical connections can be a fire hazard, therefore, we check for any issues with the wiring and connections.
- Blower Motor and Fan: The blower motor ensures proper airflow through the system. We ensure it’s functioning correctly to prevent overheating.
- Heat Exchanger: Inspect the heat exchanger for any cracks or damage. A compromised heat exchanger can lead to the release of carbon monoxide into the home.
- Thermostat Calibration: We calibrate thermostats and so it accurately communicates with the furnace.
Regular maintenance and safety checks of these components are essential to ensure that your furnace operates safely and efficiently. We recommend having a professional HVAC technician perform an annual furnace inspection and maintenance to address any safety issues and keep your heating system running smoothly.
