The Annual Rhythm
Once a year is the standard for a reason. Twelve months of sitting idle followed by four months of hard running is exactly the cycle that kills weak components. An annual visit resets the clock: cleaning, testing, measuring, and catching wear before it becomes failure.
What Skipping Costs
Skipped maintenance does not usually cause instant disaster. It causes slow decline: dirtier sensors, weaker capacitors, looser connections, each adding strain until something gives on the coldest night. The repair bill for a January emergency dwarfs the cost of a fall tune-up.
Filters: Your Monthly Job
Between professional visits, the filter is yours. Check it monthly during heating season and replace when dirty. A clogged filter is the single most common cause of preventable furnace problems, and it is the easiest thing a homeowner can control.
New Systems Need It Too
Manufacturer warranties typically require annual professional maintenance. Skipping it can void coverage exactly when you need it. New equipment also benefits from early visits that catch installation quirks while they are simple to correct.
