Mike’s Hello 🧰
Hey there, Mike Sanders here. Winter can be brutal if your furnace decides to throw in the towel when you need it most. But guess what? Most furnace breakdowns are totally preventable with a little prep.
I’m talking about a simple, straightforward checklist you can follow yourself—no rocket science, no fancy tools (well, maybe a few basic ones). So let’s get your electric furnace winter-ready and keep that warm air flowing when it counts.
1. Change or Clean Your Air Filters Regularly 🌀
Dirty filters are the #1 culprit behind furnace problems. They choke airflow, force the blower motor to work harder, and can cause overheating or tripped breakers.
Swap or clean filters every 1–3 months, depending on usage and dust load. If you have pets or allergies, lean toward monthly.
The EPA has a great guide on why clean filters matter to your furnace and your health.
2. Inspect Electrical Connections and Wiring ⚡
Loose or corroded wiring can cause intermittent furnace failures or unsafe conditions. Before winter hits, check all visible connections for wear or looseness.
If you’re not comfortable doing this, hire a pro. Electrical issues are no joke.

3. Test Your Thermostat Settings and Batteries 🎛️
Thermostat glitches are a sneaky reason your furnace might not run when you want it to. Make sure your thermostat is set to “Heat” and the temperature is above room temp.
If it runs on batteries, swap them out annually. Smart thermostats may need firmware updates or a quick reset.
4. Clean the Blower Assembly and Motor 🧼🌀
Dust and debris build-up on the blower wheel or motor can cause noisy operation or reduced airflow.
Turn off power, open the furnace panel, and use a vacuum or compressed air to clean the blower area.

5. Check Heating Elements for Damage or Wear 🔥
Heating elements wear out over time. Look for visible cracks, breaks, or scorching on the coils.
If you spot any damage, it’s time for a replacement to avoid furnace failure mid-winter.

6. Verify Proper Airflow and Ductwork Condition 🌬️
Inspect your ductwork for leaks, loose connections, or blockages. Proper airflow keeps your furnace efficient and prevents overheating.
Seal leaks with mastic and insulate ducts in unconditioned spaces.
Energy Star has a great overview on duct sealing benefits.
7. Schedule Professional Inspection and Tune-Up 🛠️
Even if you’re a DIY champ, an annual pro inspection is worth it. Technicians can spot hidden issues, test safety controls, and tune your system for maximum efficiency.
Look for contractors certified by ACCA or NATE for peace of mind.
