Cash-flow seasonality is the predictable rise and fall of the cash in your bank account across a heating and cooling year. Most HVAC companies collect heavily in late fall, deep winter and the first hot weeks of summer, then pay the same wages, truck leases and rent through the quiet shoulder months. The plan is simply to see that pattern in advance.
We are not accountants and we are not an HVAC contractor. We do not prepare forecasts for lenders, file anything, or give tax advice. This is operating coaching built on your own bank history.
What a seasonal cash map shows
A cash map plots your month-end balance against your fixed monthly costs for the last two years, then projects the next twelve months from the same pattern. The point that matters is the lowest one.
Here is an example for a company with $96,000 a month in fixed costs (wages, leases, rent, insurance, software):
| Month | Cash in | Cash out | Month-end balance | Weeks of fixed cost |
|---|---|---|---|---|
| January | $340,000 | $290,000 | $210,000 | 9.5 |
| March | $205,000 | $235,000 | $150,000 | 6.8 |
| April | $160,000 | $215,000 | $95,000 | 4.3 |
| May | $175,000 | $205,000 | $65,000 | 2.9 |
| July | $310,000 | $255,000 | $140,000 | 6.3 |
The April and May dip is not a surprise; it happens every year. What changes outcomes is knowing in January that May will bottom out near three weeks of fixed cost, and choosing what to do about it while cash is still plentiful.
The levers inside your business
When the map shows a tight month ahead, a few operating levers usually do most of the work. Each one is your decision; our role is to show its likely effect on the map.
- Agreement visit timing. Booking tune-ups in April and May keeps technicians billing in the quietest weeks.
- Deposits on replacements. Collecting a deposit when the contract is signed, not on install day, pulls cash forward.
- Receivables discipline. Commercial and property-manager accounts paid at 45 or 60 days can hold a month of cash. We track days outstanding on the dashboard.
- Program payment lag. Some utility and government programs pay the installer after paperwork is approved. Know the typical wait and plan for it.
- Equipment buying. Large pre-season orders tie up cash early. Supplier terms are a conversation for you and your distributor.
- Marketing timing. Shoulder-season campaigns for agreements and indoor air quality can smooth the dip, if the cost per booked job holds up.
What is included
- A two-year cash history by month, built from your bank and accounting exports.
- A twelve-month cash map with the lean weeks marked.
- A cash floor agreed with you, in weeks of fixed cost.
- A weekly cash line during the lean season and a monthly one the rest of the year, on your owner dashboard.
- A one-page lever list with the estimated effect of each on the map.
Who it is for
Any HVAC company with a visible winter or summer peak, which is nearly all of them. It is most useful for owners who have had a tight spring before, who are adding install crews, or who are moving into heat pumps and finding the seasonal pattern changing.
Timeline
Two to three weeks from receiving the exports to a first cash map, then monthly updates. The schedule is confirmed in writing.
How results are measured
Success is never being surprised by the low point. We report the projected low, the actual low, and the weeks of fixed cost each month, and we review the map every quarter.
Common mistakes
- Planning from revenue instead of cash. A strong March invoice paid in May is May's cash.
- Forgetting annual bills. Insurance renewals, vehicle registrations and software licences cluster; put them on the map.
- Treating a good winter as spare cash. January's surplus is what carries May.
- Leaving tax instalments off. Ask your CPA for the dates and amounts, and we add them to the map as fixed outflows.

Frequently asked questions
Is this a cash-flow forecast for my bank?
No. It is an operating plan for you. If a lender asks for formal projections or financial statements, your own CPA should prepare or review them. Our map often makes that conversation easier because the seasonal pattern is already understood.
What data do you need?
Two years of monthly bank balances, monthly revenue, payroll totals, equipment purchases and any loan payments. Exports from your accounting software are ideal, but bank statements alone are enough to start.
What is a cash floor?
The minimum balance you agree never to go below, usually expressed as weeks of fixed costs. It turns a vague worry into a number you can watch on the dashboard each week in the lean season.
Do you give tax or financing advice?
No. Tax instalments, remittances and borrowing decisions stay with your CPA and your lender. We show the operating cash pattern and the levers inside your business.
