How often should you service your furnace?
Have the furnace or heating system serviced once a year, in fall before you need it. That is the interval the HomeAlmanac app schedules for this job, adjusted for the systems your home actually has.

Why it matters
A fall heating check prevents a no-heat emergency on the coldest night and catches cracked heat exchangers that leak carbon monoxide.
How to do it
Replace the filter, test the thermostat, clear vents, and schedule a professional inspection of the burner and heat exchanger.
When to do it
Best done in fall, and the app schedules it for that season automatically.
HomeAlmanac schedules this one for you, works out the next due date each time you mark it done, and reminds you before it is late.
