IS IT TIME TO TURN ON YOUR FURNACE? BEST FALL & WINTER HEATING TIPS
January 27, 2025
As the seasons change and the temperature begins to dip, one of the most common questions homeowners ask is when to turn on their furnace.
It’s not always an easy decision. You don’t want to wait too long and risk being cold, but you also don’t want to waste energy running the heat when it’s not needed.
As one of the leading HVAC companies in Seattle, let our experts at Blue Flame Heating, Air & Electric answer that question and give you tips on how to use your furnace to save energy and money efficiently.
CONSIDERATIONS FOR SWITCHING TO HEATING
When deciding when to turn on your furnace, it's important to consider several factors. Ideal temperatures for switching are when indoor temperatures drop below 64°F and outdoor temperatures consistently dip below 60°F.
When to turn your furnace on in winter depends on these key signals, as well as personal comfort preferences and your home’s insulation efficiency.
IDEAL TEMPERATURES FOR KNOWING WHEN TO TURN FURNACE ON IN FALL
When outdoor temperatures consistently dip below 60°F, the chill begins to make indoor spaces uncomfortable, even when bundled up.
The temperature inside your home will often drop when the sun sets, so you may feel the need to turn on your furnace earlier in the evening, especially as fall settles in.
PERSONAL COMFORT PREFERENCES
Some people are more sensitive to the cold, while others may tolerate cooler temperatures longer.
If you start to notice that you’re constantly reaching for a blanket or putting on extra layers indoors, it might be a good sign that it’s time to switch on the furnace.
INSULATION RETENTION
The efficiency of your home’s insulation plays a significant role in determining when to turn on your furnace. Homes with excellent insulation and airtight seals can maintain a comfortable indoor temperature for longer, delaying the need to switch on your furnace.
On the other hand, homes with poor insulation or drafty windows and doors will lose heat much faster, requiring you to turn on your furnace earlier in the season and making it work harder.
ENERGY EFFICIENCY GOALS
For maximum efficiency, it’s advisable to wait until temperatures drop consistently below 60°F outside. Turning on your furnace too early can lead to higher heating costs and overuse.
You should aim to use the furnace in a way that reduces unnecessary operation, such as using it only during the coldest hours of the day.
When you install a heat pump, you can expect to use up to 65% less energy and save an average of $500 per year on your energy costs.
BEST TIME OF YEAR TO SWITCH TO FURNACE IN SEATTLE, WA
In Seattle, the weather can be unpredictable, especially during the fall and winter months. When to turn on your furnace depends on the seasonal weather patterns typical for the region.
Seattle’s mild winters mean you may not need the heat running every day, but the chilly, damp weather often creeps in during mid-to-late fall.
Late October to Early November is generally when you’ll start noticing consistent cold spells that might make it necessary to start running your furnace. However, many homeowners in Seattle can wait until the temperatures are consistently in the low 50s or upper 40s before turning on their furnaces, particularly if their homes are well-insulated.
Seattle residents also need to be aware of the moisture in the air, as the damp conditions can make it feel colder than the actual temperature. Turning on your furnace just before the rainy season (which often starts in late October) can help regulate humidity and maintain a comfortable indoor environment.
TIPS FOR TURNING ON YOUR FURNACE
Once you’ve decided it’s time to turn on your furnace, make sure to take a few steps to ensure it’s running efficiently and safely. Here are some essential tips:
MAINTENANCE
Before you turn on your furnace for the season, it’s important to check that it’s in good working order.
Scheduling a professional furnace inspection and maintenance service, like the ones offered by Blue Flame, can catch potential issues early and prevent breakdowns when you need the heat most.
Regular maintenance helps ensure that your furnace operates efficiently, keeping energy costs low. Schedule your regular maintenance service with Blue Flame today!
TEST THE UNIT
Once the season’s first cold front hits, make sure to test your furnace before relying on it entirely.
Switch it on for a short period to make sure it’s blowing warm air and running smoothly. If the furnace makes strange noises or you notice any strange smells or issues with airflow, it’s best to call a professional before using it regularly.
CHECK INSULATION
As mentioned earlier, proper insulation is key to energy efficiency. Before switching on your furnace, ensure that your home is adequately insulated to keep the heat inside. Inspect your windows, doors, and attic for gaps or leaks, and seal any you find.
A well-insulated home keeps warm air from escaping, allowing your furnace to operate less frequently and more efficiently.
CHECK YOUR THERMOSTAT
Make sure your thermostat is working properly and is set to the temperature you desire. Many modern thermostats are programmable, allowing you to set a schedule that matches your lifestyle.
For example, you can program your thermostat to lower the temperature while you’re away or asleep and then warm the house just before you return home. This will help reduce unnecessary furnace use and save you money.
CHECK FILTERS
Furnace filters trap dust, dirt, and debris, ensuring the air you breathe is clean. Over time, these filters can become clogged and reduce the efficiency of your furnace.
Be sure to check and replace the filters before turning on your furnace for the season. A clean filter improves airflow, helps your furnace run more efficiently, and ensures better indoor air quality.
