Seasonal advertising for service businesses: Plan for the peaks and the quiet months
Running the same budget all year means overpaying when demand is low and running out of budget when it is high.
An air conditioning company in Texas and a roofing company in Minnesota have very different calendars. Both have the same problem: a budget set in January rarely fits July.
Know your own curve
Before planning, look at your own history:
- Your lead and job data by month for the past two years, if you have it
- Google Trends for your main services in your region
- Your Google Ads account: impression share and "limited by budget" warnings by month
Most businesses find three kinds of month: peak, shoulder and quiet.
Typical patterns by trade
These are general patterns. Local climate changes them.
- HVAC: peaks at the first heat wave and the first cold snap. Repairs spike with the weather; replacements follow.
- Roofing: peaks after storms and in the months before winter. Storm-driven demand arrives suddenly.
- Solar: often steadier, with interest rising around high electricity bills and changes to incentives.
- Plumbing: fairly steady, with spikes during freezes.
- Landscaping and exterior work: strongly tied to spring and summer.
What search data shows about seasonal demand
Search volume makes the swings easy to see. These are Ubersuggest estimates of monthly US searches for common service searches, retrieved in September 2026.
| Search | Busiest month in the data | Quietest month in the data |
|---|---|---|
| ac repair | 823,000 (July 2025) | 165,000 (December 2025) |
| furnace repair | 450,000 (January 2026) | 60,500 (June 2026) |
| lawn care service | 201,000 (June and July 2025) | 60,500 (December 2025) |
| roof replacement | 74,000 (September 2025) | 18,100 (December 2025) |
Searches for AC repair ran about five times higher at the summer peak than in December, and furnace repair swung the other way by more than seven times. Your market will differ with climate and competition, but a flat monthly budget clearly does not match demand in these trades. Compare like-for-like months, not this month against last month.

Peak months
- Raise budgets before the peak, not after. Campaigns need a little time to adjust.
- Watch "limited by budget". If ads stop showing by midday, you are missing the afternoon.
- Protect capacity. There is no point buying leads you cannot answer. See what missed calls cost.
- Prioritise high-value services if you are fully booked. Pause campaigns for small jobs.
Shoulder months
- Promote maintenance, tune-ups and inspections
- Push services that are not weather-dependent
- Use seasonal offers that are true and time-limited
Quiet months
Quiet months are not wasted months. Use them to:
- Collect reviews from peak-season customers
- Film new creative on the jobs you do have
- Test new landing pages while traffic is lower-stakes
- Build retargeting audiences with lower-cost awareness campaigns. See retargeting for service businesses.
- Keep a baseline Search campaign running for emergency and brand searches
Illustrative example
These numbers are invented to show the approach.
An HVAC company spends $3,000 a month all year. In July, campaigns run out of budget by 1pm. In February, cost per job doubles because demand is low. Shifting to $4,500 in peak months, $3,000 in shoulder months and $1,500 in quiet months keeps annual spend the same, and produces more jobs at a lower average cost.
Use seasonality settings with care
If you use automated bidding in Google Ads, sudden short spikes such as a storm or a sale can confuse it. Google's seasonality adjustments let you tell Smart Bidding to expect a short change in conversion rates. They are for short events of a few days, not whole seasons.
Where to start
Plot your leads by month for last year and mark the peaks. Then set next year's budget by month instead of one flat number.

Questions owners ask
Should I stop advertising in the quiet season?
Usually not entirely. Keep a baseline for emergency and brand searches, and use the time to build reviews, creative and audiences for the next peak.
How early should I raise budgets before peak season?
A week or two before demand usually rises, so campaigns have time to adjust. Watch search trends in your area as a guide.
What are seasonality adjustments in Google Ads?
They are a setting that tells Smart Bidding to expect a short-term change in conversion rates, for example during a sale or storm. They are meant for events of a few days.
When is the busy season for HVAC companies?
In most US markets, cooling demand peaks in mid-summer and heating demand in mid-winter, with quieter spring and autumn months in between. In the search data above, "ac repair" peaked in July and "furnace repair" in January. Your own call history is the best guide for your area.
