10 Easy Steps to Turn On Your Furnace

Furnace

Feel that chill in the air? The days are getting shorter, and the nights colder. Soon, you’ll need to turn on your furnace to keep your home warm and comfortable. But if you’re not sure how to do it, don’t worry. We’ll walk you through the steps in this article. Turning on your furnace is a simple process that anyone can do, and it only takes a few minutes. So grab a screwdriver and let’s get started!

Before you turn on your furnace, there are a few things you should do first. First, check the air filter. A dirty air filter can restrict airflow, making your furnace work harder and less efficiently. If the filter is dirty, replace it with a new one. Second, make sure there are no obstructions around the furnace. Clear away any furniture, boxes, or other objects that could block the airflow. Third, check the thermostat. Make sure the thermostat is set to “heat” and that the temperature is set to a comfortable level. Once you’ve done these things, you’re ready to turn on your furnace.

To turn on your furnace, simply find the switch or knob that controls the power. It is usually located on the front or side of the furnace. Turn the switch or knob to the “on” position. You should hear the furnace start up. If you don’t hear the furnace start up, check the circuit breaker or fuse box to make sure that the power is on. Once the furnace is on, it will take a few minutes to start heating up your home. You should start to feel warmer within 30 minutes or so. If you don’t feel warmer after 30 minutes, check the thermostat to make sure it is set to the correct temperature. You may also need to adjust the fan speed on the furnace to increase the airflow.

Familiarize Yourself with Your Furnace

Before attempting to turn on your furnace, it is crucial to gain a thorough understanding of the system and its various components. By familiarizing yourself with the furnace, you can operate it safely and efficiently, ensuring optimal performance and longevity.

Locate the furnace unit, which is typically situated in the basement, attic, or a utility closet. The furnace comprises several essential components, including:

Blower: Responsible for circulating warm air throughout the ducts and into the living space.
Burner: Ignites the fuel (gas or oil) to generate heat.
Heat exchanger: Transfers heat from the combustion chamber to the air passing through the furnace.
Thermostat: Senses the room temperature and sends a signal to the furnace to start or stop heating.
Control panel: Provides access to various settings, including temperature adjustment and troubleshooting.
Ductwork: Distributes the heated air throughout the house.
Filter: Removes dust and particles from the air before it is circulated.

Understanding the location and function of each component will enable you to troubleshoot minor issues as they arise and ensure the safe and efficient operation of your furnace.

Adjust the Thermostat Settings

Once you have located your thermostat, it is time to adjust the settings to turn on your furnace. Here’s a step-by-step guide to help you through the process:

1. **Check the Mode:** Ensure that the thermostat is set to “Heat” or “Auto” mode. This will tell the thermostat to start heating your home when the temperature drops below the set point.

2. **Adjust the Temperature:** Use the up and down buttons to set the desired temperature for your home. The ideal temperature range for comfort and energy efficiency is between 18-21 degrees Celsius (64-70 degrees Fahrenheit).

3. **Set the Fan:** Most thermostats have a fan setting that can be adjusted to “On,” “Auto,” or “Circulate.” “On” will keep the fan running continuously, which can help distribute heat evenly but may also increase energy consumption. “Auto” will run the fan only when the furnace is heating, while “Circulate” will run the fan intermittently to help circulate air without heating it.

Fan Setting	Description
On	Fan runs continuously
Auto	Fan runs only when the furnace is heating
Circulate	Fan runs intermittently without heating

Check the Pilot Light (Optional)

If your furnace has a pilot light, it needs to be lit before you can turn on the furnace. To check the pilot light, follow these steps:

Locate the pilot light. It is usually located in a small window on the front of the furnace.
Turn the gas valve to the “Pilot” position. This will allow gas to flow to the pilot light.
Hold a lit match or lighter to the pilot light. The pilot light should ignite and stay lit.

If the pilot light does not ignite, check the following:

Make sure that the gas valve is turned to the “Pilot” position.
Make sure that the thermocouple is clean. The thermocouple is a small metal rod that is located near the pilot light. Its job is to sense the heat of the pilot light and send a signal to the gas valve to keep the gas flowing. If the thermocouple is dirty, it may not be able to sense the heat of the pilot light and the gas valve will shut off the gas flow.

Make sure that the pilot light is not blocked by anything. If the pilot light is blocked, it may not be able to ignite.

If you are unable to light the pilot light, call a qualified HVAC technician for assistance.

Professional Tips

To ensure your furnace operates efficiently and safely, consider these professional tips for turning it on:

1. Safety Checks

Before turning on the furnace, perform the following safety checks:

Inspect the furnace visually and ensure there are no leaks, cracks, or blockages.
Check the gas supply valve to ensure it’s open if applicable.
Clear any obstructions around the air intake and exhaust vents.

2. Locate the Thermostat

Identify the thermostat and set the desired temperature.

3. Power the Furnace

Locate the furnace’s main power switch or circuit breaker and turn it on.

4. Clean the Air Filter

Replace or clean the air filter to ensure optimal airflow.

5. Activate the Furnace

Switch the furnace’s mode to “Heat” and use the thermostat to control the temperature.

6. Monitor the Venting System

Ensure the furnace vents are clear and unobstructed to prevent combustion fumes from accumulating.

7. Test the Safety Features

Operate the furnace for a few minutes and observe if the blower motor, igniter, and other safety features are functioning properly.

8. Adjust the Thermostat

Once the furnace is running, adjust the thermostat to the desired temperature and check the accuracy of the reading.

9. Monitor the Operation

Monitor the furnace’s performance regularly and listen for any unusual noises or odors.

10. Troubleshooting

If the furnace fails to turn on or operates abnormally, follow these troubleshooting steps:

Issue	Possible Cause
No Power	– Blown fuse or tripped circuit breaker – Faulty wiring
No Ignition	– Faulty igniter – Blocked gas supply
No Heat	– Clogged air filter – Malfunctioning blower motor
