Every trade business in Los Angeles knows the shape of its year, even if nobody has drawn it. HVAC shops are flat out from the first heat wave until September, then quiet until the first cold snap, and quiet again in spring. Roofers watch the forecast for the first rain. Landscapers are busiest when things grow and when the water bill arrives. Plumbers and electricians have flatter years, but they still have weeks when the board thins out.
The quiet stretches between the busy ones are the shoulder months. They come every year, at roughly the same time. And yet for many shops they arrive as a surprise: the phones slow down, the techs are sent home early or kept busy with shop work, and the owner turns the ads up in a hurry to make the phone ring.
Why a slow month is a leak
A slow month does not look like a leak. Nothing was missed. Nobody hung up on a voicemail. There simply was less work.
But the costs do not slow down. The trucks, the insurance, the office and the techs you want to keep all cost roughly the same in April as in July. A tech who is paid for a full week and runs three calls is capacity you paid for and did not sell. That capacity is the leak: not money that walked out the door, but hours that could have been sold and were not.
The good news is that the shoulder months are the most predictable part of the year. You know they are coming. You can plan work into them months in advance, which you cannot do for a heat wave.
Know your own curve first
Before planning anything, look at your own history. Pull the last two or three years from the field software and chart, by week:
- Jobs completed.
- Inbound calls and forms.
- Revenue.
- Techs on payroll.
The weeks where jobs drop and payroll does not are your shoulder months. They may be narrower than you think: not “spring” but three specific weeks in April, and a stretch from mid-September to the end of October. Knowing the exact weeks makes everything below easier to schedule.
Work you can move into the quiet weeks
The most reliable way to fill a slow month is with work that can be scheduled rather than work that has to be found. Many shops have more of it than they use.
| Trade | Work that can be planned into the shoulder |
|---|---|
| HVAC | Member tune-ups, duct cleaning and sealing, indoor air quality work, replacement estimates for units that struggled in summer |
| Plumbing | Water heater flushes and inspections, camera inspections, fixture upgrades, repipe estimates held from the busy season |
| Electrical | Panel inspections, EV charger installs, lighting upgrades, surge protection, estimates for work customers deferred |
| Roofing | Pre-rain inspections and maintenance in late summer and early fall, gutter work, repair backlogs |
| Landscaping | Irrigation audits and controller upgrades, planting in fall, drought-tolerant conversions, cleanup ahead of the rains |
Three sources of this work are already sitting in your records.
Your members. If you sell maintenance agreements, the visits are the most obvious shoulder-month work there is. Call members in the weeks before the slow season and book them into it. We covered how those plans leak when nobody works the list in HVAC maintenance plans and the renewals that lapse.
Your deferred work. Every busy season produces customers who were told “you’ll need to replace that soon” and said “not now”. Those notes are in the job history. A call in the quiet month, when you have the capacity to do it properly, is a reasonable follow-up, not a cold call.
Your open estimates. Quotes from the summer that were never accepted or declined. Some are dead. Some were simply put off, and the customer would take a date in October.
Advertising in the shoulder months
The instinct in a slow month is to spend more on ads. Sometimes that is right. Often it is the most expensive way to fill the calendar, because in the shoulder months demand for your most common service is genuinely lower, and you are bidding against everyone else who had the same idea.
A few things tend to work better:
- Change what you advertise, not just how much. In spring, an HVAC shop advertising emergency AC repair is paying for a thin market. Ads for tune-ups, system checks or replacement estimates meet the people who are thinking ahead.
- Plan ad changes ahead of the curve. Campaigns take time to settle after changes. Adjust them a few weeks before the slow period, not after it starts.
- Lean on your own list first. An email or text to past customers costs very little compared with paid clicks and reaches people who already know you.
- Pull back where demand has fallen. Keeping emergency-repair budgets at summer levels in a quiet month often means paying more per job, not getting more jobs.
The measure is the same as always: cost per booked job, not cost per click. In our paid ads work, the budget is planned to follow the seasonal curve rather than a flat monthly figure.
A simple calendar
Here is a rough planning rhythm. The months are an example for a Southern California HVAC shop; move them to fit your own curve.
- Six to eight weeks before the slow period: review the curve, set the target number of planned jobs, and pull the lists (members, deferred work, open estimates).
- Four weeks before: start calling members and deferred-work customers; adjust ad campaigns toward shoulder-season services.
- Two weeks before: check how full the quiet weeks are; if there are gaps, send the past-customer email or text.
- During: use any slack for training, truck maintenance and the office projects that never get done in summer. That is not wasted time, but it should be a choice rather than a default.
- After: look at how the planned weeks went, and write down what to start earlier next year.
Landscaping and roofing will have different months. The rhythm is the same: know the weeks, pull the lists early, fill the calendar with work you can schedule, and only then ask the ads to do the rest.
Landscapers often have the most seasonal curve of the five trades we focus on; there is more on that trade on our landscaping page. Wherever you sit, the simplest first step is to chart last year by week and circle the quiet ones.
