Winters around Tacoma and Seattle can get chilly fast, and they don’t always follow the same pattern year to year. Some days bring heavy rain, others drop into freezing temps overnight. One thing’s for sure: you don’t want to find out your furnace isn’t working right when it’s already cold outside. Furnace winter readiness means giving your system a look now so it won’t let you down later. This quick guide runs through ten simple things you can check before that cold weather really settles in.
Give the Thermostat a Quick Check
Start with the device that controls it all. Set your thermostat a few degrees higher than the current room temperature and switch it to heating mode. You should hear the furnace start shortly after. Feel around your vents to make sure warm air is flowing.
If nothing happens, there might be an issue with the settings, wiring, or power source. While you’re at it, check if the batteries need replacing. If your model is older or hard to use, think about moving to a programmable thermostat, which can make day-to-day comfort easier year-round.
Replace or Check the Air Filter
A clean filter helps your furnace breathe and heat more easily. During heating season, we recommend checking the filter once a month. If it looks gray or dusty, it’s time to change it out. A clogged filter makes your furnace work too hard, which can raise your energy bills and shorten the system’s lifespan.
Swapping in a fresh filter takes just a minute, but adds real comfort and helps keep your air cleaner too.
Look and Listen Around Your Furnace
Take a few minutes to glance around your furnace and listen while it’s running. If you spot boxes, furniture, or storage bins nearby, move them so there’s nothing blocking airflow or access.
As the system warms up, listen for any sounds that don’t seem right. Banging, rattling, screeching, or grinding are all signs something might be loose or off balance. Any strong odors could also mean a part isn’t working the way it’s supposed to. If anything feels off, now’s the time to schedule a heating system inspection.
Inspect the Vents and Air Registers
Walk through your home and make sure each vent is open and free from anything blocking it. Look out for rugs, curtains, or furniture that might be blocking airflow. Even something small can slow down how air moves from one room to another.
Use a vacuum or duster to clear away dust around each register. You might also notice that some rooms feel cooler than others. If that’s the case, it could be a sign of low airflow, closed vents, or leaky ducts.
Check the Furnace Flame (If Visible)
If you have an older gas furnace, there may be a small window where you can view the burner flame. A clear blue, steady flame is what you want to see. If it’s yellow, flickering, or looks weak in any way, that could point to a burner or airflow issue.
Do not try to fix this yourself. Strange flames mean it’s time for a closer look from someone trained to work on gas systems.
Make Sure Carbon Monoxide Detectors are Working
When the furnace runs more often in winter, the risk of carbon monoxide exposure can go up. That’s why checking your detectors is just as important as checking the heating equipment. You should have one on every level of your home.
Push the test button on each unit and swap the batteries if needed. If a detector ever sounds an alert, leave your home immediately and call for help.
Plan for a Professional Heating System Inspection
Even if your system seems to be running fine, an annual heating system inspection still makes sense. It helps us catch small problems early, long before they turn into larger repairs. We’ll clean internal parts, check safety switches, and make sure the overall system is working the way it should.
Booking this before winter gets worse helps avoid mid-season breakdowns when you need heat most. Home Comfort Alliance offers professional maintenance checks and priority scheduling for emergency repairs in the Puget Sound area. All furnace tune-ups are conducted by certified technicians with decades of hands-on experience in both gas and electric heating systems.
Watch for Signs of Short Cycling
If your furnace turns on and off quickly over and over again, that could be a sign of short cycling. This isn’t just annoying; it’s hard on the system. It can mean your furnace is too large for the space, something’s overheating, or airflow is being restricted.
Short cycling can lead to higher utility bills, more wear on parts, and uneven heat throughout the house. Left unchecked, it might even shorten the life of your system.
Keep an Eye on Energy Bills
Your furnace may be working, but is it working harder than it should? A good way to tell is by looking at your utility bills. If this month’s total is much higher than the same time last year, your furnace might be running longer or less efficiently than it used to.
Dirty filters, faulty thermostats, or worn-out components could be to blame. Whatever the reason, a big change in your bill is a red flag that shouldn’t be ignored. Comparing past seasons can give you a clear sense of how things are trending.
Stay Ready for the Cold: Your Furnace, Your Peace of Mind
