The furnace parts that fail on the coldest night of the year, such as the igniter, the flame sensor, the inducer motor and the pressure switch, almost always show warning signs weeks or months earlier. A fall furnace tune-up is how you find them in September, on a calm afternoon, at regular rates, instead of at 3am in January when it's 25 below and every heating company between Fargo and Bemidji is running behind.
Waubun HVAC Pros provides furnace maintenance, combined heating-and-cooling maintenance, and an annual maintenance plan for homes across Waubun, Ogema, Mahnomen and the surrounding area.
The fall furnace tune-up
Ignition and flame. We inspect and test the hot-surface igniter, clean the flame sensor, and check the flame signal. A weak flame signal is the number-one predictor of a furnace that will start shutting itself off once cold weather hits.
Combustion and safety. We check gas or propane pressure, burner condition and flame pattern, inspect the heat exchanger for visible cracks or corrosion, and test for carbon monoxide at the appliance. We test the limit, rollout and pressure switches to confirm the furnace will shut down safely if something goes wrong.
Draft and venting. On high-efficiency furnaces we inspect the PVC intake and exhaust from the furnace to where they leave the house, check the condensate trap and drain, and make sure the terminations sit high enough to clear typical snow drifts. On older furnaces with metal flues, we check for proper draft and corrosion in the vent connector.
Airflow. We measure temperature rise and check the blower motor, capacitor and blower wheel. A restricted system with a dirty filter, a caked blower wheel or closed-off returns overheats the heat exchanger and shortens the furnace's life.
Why maintenance matters more in northwest Minnesota
A furnace in Waubun can run thousands of hours between October and April, far more than one in a milder climate. Many homes here heat with propane, where a lockout on a cold night means an expensive emergency call and possibly frozen pipes. And for homes on Wild Rice Electric's off-peak program, the backup furnace may sit idle for weeks and then be called on suddenly during a control period, which is exactly when a weak igniter or dirty sensor reveals itself. Regular maintenance is cheap insurance against all of that.
Heating and cooling in one visit
If you have central air or a heat pump, we can service it in the same visit. The AC coil usually sits right on top of the furnace, so checking both at once makes sense. For cooling-specific spring service, see AC Maintenance. For heat pumps, which work in both seasons, see Heat Pump Services.
The annual HVAC maintenance plan
If you'd rather not remember to call every year, our annual plan covers one fall heating tune-up and one spring cooling tune-up at a fixed yearly price. Plan members get priority scheduling. When a cold snap brings a wave of no-heat calls, plan customers go to the front of the line. We'll call you when your tune-up is due so you don't have to keep track.
Between visits: what homeowners can do
- Change the furnace filter every one to three months during heating season, and more often with pets, a woodstove or a dusty gravel road nearby.
- Keep the PVC vent pipes outside clear of snow all winter, especially after a storm.
- Don't close off more than a couple of supply registers, and keep return grilles clear of furniture and storage boxes.
- Test your carbon monoxide alarms monthly and replace them per the manufacturer's date (usually 7 to 10 years).
- If your propane tank gauge drops near 20%, call for delivery. Running out means a leak check and a relight before the furnace can run.
Schedule your furnace tune-up
September and October are the ideal months. Call (218) 227-4357 or book around your schedule: Mon–Fri 8am–10pm, Sat–Sun 9am–8pm.
Technician insight
The flame signal reading tells me more about how a furnace will behave in January than anything else. If it's marginal in September, it'll start shutting off on cold nights. A two-minute cleaning now saves you a 2am call later.
What a Fall Tune-Up Usually Catches
A common fall tune-up finding around Waubun: a 12-year-old high-efficiency propane furnace that ran fine last winter shows a weak flame signal, a hairline crack starting in the igniter, and a condensate trap half full of sludge. Cleaning the sensor, replacing the igniter before it fails and flushing the trap costs a fraction of an emergency visit and keeps the furnace running through the winter.
