Saving Electricity and Fuel During Warm Months
During the warmer months, it is common for homeowners to turn off their home furnaces in order to save electricity and fuel. Since the furnace is not required to provide heat during this time, shutting it down can help reduce energy consumption and lower utility bills. This practice is particularly beneficial for those living in regions with mild climates, where the need for heating is minimal.
By turning off the furnace, homeowners can ensure that they are not wasting energy and running up unnecessary costs. However, it is important to remember that when the colder months arrive, the furnace will need to be properly turned on again. This process involves:
- Restoring the power supply
- Removing the front access panel
- Adjusting or lighting the pilot light
- Replacing panels
- Setting the thermostat
By following these steps, you can ensure that your furnace is ready to provide reliable and efficient heating when you need it.
Restoring Power Supply and Removing Front Access Panel
Before turning on your furnace, the first step is to restore the power supply and remove the front access panel. Make sure that the power to your furnace is turned off completely in order to avoid any potential accidents or injuries. Once you have done this, locate the front access panel of the furnace. It is usually located near the bottom of the unit and can be removed by unscrewing the fasteners or latches that hold it in place.
Removing the front access panel allows you to access the inner components of the furnace, such as the pilot light and the burner. It is important to exercise caution while handling the panel and ensure that it is properly set aside in a safe place. This will prevent any damage to the panel and allow for easy reinstallation once you have completed the necessary steps to turn on the furnace.
Adjusting or Lighting the Furnace Pilot Light
Once you have removed the front access panel, you may need to adjust or light the furnace pilot light. Some furnaces have a pilot light that needs to be adjusted using a screwdriver, while others require you to manually light the pilot by purging gas before igniting it. Consult your furnace’s user manual or contact a professional if you are unsure about the specific instructions for your furnace model.
To adjust the pilot light, locate the pilot light assembly. This usually consists of a small flame located near the burners. If the flame is not burning steadily or is flickering, you may need to adjust it by turning the pilot light adjustment screw with a screwdriver. Follow the manufacturer’s instructions for your particular furnace model to perform this adjustment correctly.
If your furnace requires you to manually light the pilot, ensure that the gas supply valve located near the furnace is turned on. Hold down the pilot button or control knob, depending on your furnace model, and purge the gas by pressing the reset button or igniting the gas manually. Once the gas is purged and flowing, light the pilot with a long-handled lighter.
Replacing Panels and Setting the Thermostat
After adjusting or lighting the pilot light, it is time to carefully replace the panels and covers that were removed earlier. Take care to align the fasteners or latches properly and secure them tightly to ensure that the furnace is sealed correctly. This will prevent any air leaks and ensure that the furnace operates efficiently.
Once the panels are securely in place, it is time to set the thermostat. Locate your thermostat, which is usually installed on a wall near the furnace or in a central location in your home. Adjust the temperature setting to your desired level, taking into consideration the current weather conditions and your comfort preferences. Make sure the thermostat is set to “heat” mode and that the fan is set to “auto” or “on” depending on your preferences.
Setting the thermostat correctly will ensure that your furnace operates efficiently and provides the desired level of heating. It is important to periodically check and adjust the thermostat settings as needed to maintain a comfortable indoor environment and conserve energy.

Troubleshooting Common Issues
Despite following the necessary steps to turn on your furnace, you may face two common issues that require troubleshooting: dirty filters and blown fuses.
Dirty filters can significantly reduce the efficiency of your furnace by obstructing the airflow. It is important to regularly inspect and clean or replace the filters to ensure proper airflow and optimal performance.
Blown fuses can occur due to electrical issues or power surges. If your furnace is not turning on even after following the proper startup procedure, check the circuit breaker or fuse box to see if a fuse has blown. If necessary, replace the blown fuse or reset the circuit breaker.
If you are unable to resolve these issues yourself, it is advisable to contact a professional HVAC technician who can diagnose and repair any complex problems with your furnace.
Dealing With Dirty Filters and Blown Fuses
Dirty filters can easily be addressed by following a simple maintenance routine. Start by switching off the power supply to your furnace. Locate the air filter, which is typically located near the air handler or within the return air grille. Remove the filter and inspect it for dirt and debris. If the filter is dirty, clean it by gently rinsing it or replace it with a new one if it is heavily soiled or damaged. Once the filter is clean or replaced, reinstall it securely.
Blown fuses can be more complicated to address, especially if you are unfamiliar with electrical systems. In such cases, it is best to seek the assistance of a qualified electrician or HVAC technician who can safely diagnose and rectify the issue. They will have the necessary expertise and tools to replace the blown fuse and investigate any underlying electrical problems that may have caused the issue.
Properly turning on your furnace involves a series of steps that ensure efficient and safe operation. By following the guidelines provided in this article and conducting regular maintenance, you can ensure that your furnace operates optimally, providing you with reliable and comfortable heat during the colder months. Additionally, proper troubleshooting of common issues such as dirty filters and blown fuses can help prevent unexpected breakdowns and prolong the life of your furnace.
Frequently Asked Questions
Where is the switch to turn on the furnace?
The switch to turn on the furnace is typically located within sight of the furnace, as required by most building codes. The switch, also known as a disconnecting means, can usually be found mounted on the side of the furnace or on a nearby wall. This ensures easy access and visibility, allowing users to safely control the furnace’s operation.
How do I know if my furnace is turned on?
When determining if your furnace is turned on, start by locating the power switch near the furnace or on a nearby wall. Ensure that the switch is in the on position to activate the furnace. Additionally, it is advisable to inspect your circuit breaker or fuse box, as a tripped breaker or blown fuse may have caused the furnace to lose power. By checking these components, you can verify if your furnace is turned on and operational.
When should I turn on furnace?
In order to determine when to turn on your furnace, it is recommended to consider the indoor temperature. Experts advise turning on the heat when it falls below 64 degrees Fahrenheit. However, if there are children, seniors, or individuals who are ill in the household, it may be necessary to raise this threshold slightly for their comfort. Moreover, to optimize energy usage, it is recommended to set the thermostat lower when going to bed, ensuring a cozy sleep while being mindful of energy consumption.
1. What are the steps to properly turn on a gas furnace?
To properly turn on a gas furnace, there are a few important steps to follow. First, ensure that the thermostat is set to a temperature higher than the current room temperature. This will signal the furnace to turn on. Next, check that the furnace’s power switch is set to the “on” position. If there is a pilot light, make sure it is lit. If not, follow the manufacturer’s instructions to light it safely. Finally, listen for the sound of the furnace igniting and feel for warm air coming out of the vents. If the furnace does not turn on or you encounter any issues, it is best to call a professional technician for assistance to ensure safety and efficiency.
