The Best Time of Year to Tune a Piano in Ontario

Every fall the phone lights up the week the furnace comes on — and every fall we gently explain why that's the one week we'd rather not tune your piano. The best time to tune isn't a date; it's a condition: after the indoor climate has settled into a season, not while it's changing. In Ontario that gives two ideal windows, two transitional stretches to avoid, and a couple of calendar events worth planning around. Here's the technician's calendar.

Why timing matters at all

A piano's pitch follows its soundboard, and the soundboard follows indoor humidity. When the furnace starts in October, the house dries out over two to four weeks and the piano drifts flat as it does; when windows open and humid air arrives in May, the reverse. A tuning done during those transitions is chasing a moving target — the fine edge of the work is gone within days, through no fault of the tuner. A tuning done once the house has reached its seasonal baseline sits stably for months.

The two ideal windows

Late fall to mid-winter (mid-November through February). The furnace has been running for weeks, the house has reached its dry-season baseline, and the piano has finished its autumn sag. A tuning now holds through the rest of the heating season. This is the single most popular — and sensible — time for an annual tuning: it also puts the piano in shape for the holidays, when it gets played most. Pair it with the winter care routine.

Early to mid-summer (mid-June through August). The humid season has arrived and settled, the piano has finished its spring rise, and a tuning holds through to fall. The natural second window for grands and serious players on a twice-yearly rhythm, and a good single-tuning choice for households that play most in summer. Pair it with summer humidity care.

The two stretches to avoid

The furnace fortnight (roughly early to mid-October, depending on the weather). The house is drying fast; the piano is mid-sag. If you tune now, expect it to sound slightly off by November.

The window-opening weeks (late April to May). Humidity climbing, piano rising. Same problem in reverse.

If you're already booked in one of these — don't cancel; a tuning is never wasted, and the guarantee covers anything that genuinely slips. Just know that the ideal is a few weeks either side.

Timing for events

• Holidays: tune in late November or early December — settled into the dry season, fresh for the busiest playing weeks of the year. Book early; December fills.
• Exams, recitals, festivals: two to four weeks before the date, whatever the season — settled but still true.
• A move: two to four weeks after the piano arrives in the new room, never on moving day.
• A new piano: first tuning two to four weeks after delivery, then a first-year schedule of three or four.

One tuning a year? Pick the season you play most

Most home pianos do well on one annual tuning (why once a year is the right floor). Choose the window that precedes the months the piano actually gets used — for most families, that's the late-fall tuning ahead of winter evenings and the holidays. Then hold that date every year; a piano tuned at the same point in each seasonal cycle drifts the least between visits.

Twice a year? Mid-winter and mid-summer, one in each window. That's the grand-piano and serious-student rhythm, and it's what studios and churches should run on.

Whenever you land: keep the room steady between tunings — a humidifier in winter, AC or a dehumidifier in summer — and every tuning lasts closer to its full potential. Book yours here.

Common questions

What month is best to tune a piano in Ontario?
Late November through February, once the furnace has dried the house to its winter baseline — or June through August, once summer humidity has settled. Avoid the transition weeks in October and May.

Should I tune my piano before winter or after it starts?
After the heating season has settled in — a few weeks after the furnace begins running regularly. Tuning right before or right as it starts means the piano drifts within days as the house dries.

Is it bad to tune a piano in the fall?
Not bad — just less ideal during the two or three weeks the house is actively drying out. Late fall, once things have settled, is one of the best times of the year.
