Stay Safe this Winter with These 7 Furnace Safety Features

It is hard to imagine winters without furnace installation in Portland. Cold indoor temperatures can even lead to Hypothermia in older people. If the body temperature of a senior citizen is 95° or lower, there are several health risks like a heart attack and kidney or liver damage.

Furnace Mechanism and Safety Features

A furnace is a combustion system that can cause hazards and other dangers. However, we don’t have to worry about these issues because our furnace has many safety features to prevent potential dangers. The seven furnace safety features everyone should be aware of are mentioned below.

1. Install a Surge Protector

A surge protector detects power surges and protects us from many electrical hazards. There can be many issues with the electrical power supply and connections, which can cause a short circuit or fire hazards.

A surge protector senses such conditions beforehand and shuts down the furnace unit. Maintaining the electrical conditions of your furnace system will reduce furnace repairs in Portland by preventing electrical damage to the heating unit.

2. Smoke and Carbon Monoxide Detectors

Smoke and carbon monoxide cause several health issues. An increase in smoke levels can lead to respiratory issues and breathing problems. A carbon monoxide leak can also make you severely ill and even lead to death.

After furnace installation in Portland, you should also install a smoke and carbon monoxide detector alarm in each room.

3. Pressure Switch

An air pressure switch is an essential component of the furnace as it monitors the air pressure of the fan. The fan pulls the flame and pushes the exhaust. This process ensures air quality and safety.

If the fans or the flue pipe gets blocked, there will be an imbalance in the air pressure. The pressure switch detects this imbalance. Then, it trips and shuts down the furnace system. When the pressure switch trips, you should contact one of our experienced technicians to fix the air pressure-related problems.

4. Flame Sensor

As the name suggests, a flame sensor detects the flame ignited through the ignitor. The flame sensor detects an ignition failure and turns off the gas supply. The ignition failure can even result in explosion danger, and the flame sensor prevents this danger.

If your flame sensor often turns off the gas supply, contact an HVAC professional for furnace repair in West Linn, OR.

5. Limit Switch

The limit switch detects the temperature of the heat exchanger and airflow. If it senses overheating of the furnace, it will trip and shut down the system preventing fire risks.

6.Triggered thermocouple

The standing pilot light in older furnace units generates low flame or causes inefficient burning, and the thermocouple detects it. The inefficient burning also causes carbon monoxide leaks.

The thermocouple prevents this leakage by shutting off the gas supply. When the thermocouple shuts off the furnace system, you should immediately schedule a heating repair lake oswego

7. Flame Roll-Out Switch

Another safety feature of the furnace is its flame roll-out switch which ensures that the flame stays within the combustion chamber. Sometimes, improper gas supply can lead to flame entering other parts of the furnace unit.

It can be extremely dangerous for the furnace unit and your house. The flame roll-out switch trips a furnace and prevents the negative consequences of flame from entering other parts of the heating unit.


These seven safety features prevent risky and harmful situations. It’s recommended to also schedule an annual tune-up to maintain the quality of the safety components of the furnace. There will be no benefit if the safety components are not in quality condition.
