With the onset of colder months, ensuring your home remains warm and comfortable becomes a top priority. Among the essential home appliances that keep you cozy during winter is your furnace. However, if you’re new to operating a furnace or haven’t used it in a while, turning it on for the first time can be daunting. To simplify this task, we’ve compiled a comprehensive guide to help you navigate the process of turning on your furnace safely and efficiently.
Before you proceed with turning on your furnace, it’s crucial to conduct a thorough inspection to ensure its readiness for operation. Begin by confirming that the gas or electricity supply to your furnace is active and unobstructed. Inspect the furnace’s air filter to determine if it needs replacing. A dirty or clogged filter can impede airflow and reduce the furnace’s efficiency. If necessary, replace the filter with a new one to optimize airflow and protect your furnace from potential damage.
Once your furnace has passed the preliminary inspection, you’re ready to initiate the power-up process. Locate the furnace’s thermostat and set it to a temperature higher than the current room temperature. This will signal the furnace to begin heating the air. Depending on the type of furnace you have, there may be additional switches or buttons that need to be activated. Consult your furnace’s user manual for specific instructions and safety guidelines.
Engaging the Gas Supply Valve
The route to a cozy home during the cold season can be found in a functional furnace. Yet, if you’ve recently moved into a house or are puzzled by a cold house despite a turned-on furnace, checking the gas supply valve is a crucial step.
Here’s a step-by-step guide to engaging the gas supply valve:
1. Identify the valve: Locate the gas supply valve near your furnace or water heater. It’s typically a yellow handle that runs perpendicular to the gas pipe.
2. Determine the valve’s position: The valve can be in one of two positions: parallel to the pipe (closed) or perpendicular to the pipe (open).
3. Open the valve: If the valve is closed, carefully turn the handle a quarter turn counterclockwise. This should align the handle perpendicular to the pipe, indicating an open gas supply.
| Valve Position | Gas Supply Status |
|---|---|
| Parallel to pipe | Closed |
| Perpendicular to pipe | Open |
Operating the Furnace Fan Switch
The furnace fan switch controls the operation of the furnace’s fan, which circulates air throughout the home. There are typically three fan settings: “Auto,” “On,” and “Circulate.”
Setting the fan switch to “Auto” allows the furnace to automatically turn the fan on and off as needed to maintain the desired temperature in the home. Setting the fan switch to “On” keeps the fan running constantly, regardless of the temperature. Setting the fan switch to “Circulate” keeps the fan running continuously, even when the furnace is not heating the home. This setting is useful for circulating air and improving air quality.
Here are some additional details about the fan switch settings:
Auto Setting
- The furnace fan will only run when the furnace is heating the home.
- This setting is the most energy-efficient, as it only runs the fan when it is needed.
On Setting
- The furnace fan will run continuously, regardless of whether the furnace is heating the home.
- This setting can be useful for circulating air and improving air quality.
Circulate Setting
- The furnace fan will run continuously, even when the furnace is not heating the home.
- This setting can be useful for circulating air and improving air quality.
- This setting is not as energy-efficient as the “Auto” setting.
| Setting | Operation | Energy Efficiency |
|---|---|---|
| Auto | Furnace fan runs only when heating | Most energy-efficient |
| On | Furnace fan runs continuously | Less energy-efficient than “Auto” |
| Circulate | Furnace fan runs continuously, even when not heating | Least energy-efficient |
| Time of Day | Recommended Temperature |
|---|---|
| When you’re home and awake | 68-72°F (20-22°C) |
| When you’re home and asleep | 62-65°F (17-18°C) |
| When you’re away from home | 58-60°F (14-16°C) |
Remember that these are just guidelines, and you should adjust the temperature based on your personal comfort level. Using a programmable thermostat to automate these temperature changes can save you up to 10% on your energy bills.
