HVAC · Michigan
Your busy season pays for your slow season. You should know by how much.
HVAC money moves in a rhythm most bookkeepers have never had to account for. Books that ignore that rhythm tell you nothing useful in February.

HVAC bookkeeping for Michigan contractors
We provide monthly HVAC bookkeeping for heating and air conditioning contractors across the United States — everything from a single-truck operation to a shop running fifteen techs. Every set of books is reconciled, closed monthly, and reviewed and signed off by a US CPA before it reaches you.
HVAC accounting has requirements a general bookkeeper will not account for: revenue that swings hard between cooling and heating season, maintenance agreements that need their own margin tracking, and install work that has to be separated from service work before job costing means anything. That is what an HVAC bookkeeper who knows the trade builds in from the first month.
What is different in Michigan
Michigan makes this trade harder than average.
Season and demand
Long, severe winters make heating the dominant load, and the cooling season is short. Freeze-thaw cycles drive burst pipes and emergency call volume that arrives all at once rather than steadily.
The market
A repair and replacement market with older housing stock and a substantial industrial base. Seasonality is sharp enough that shoulder-season cash planning matters more here than in warmer states.
Tax and entity context
Michigan applies a flat personal income tax rate. Several cities levy their own local income tax on top, so businesses operating across municipal lines have an extra layer to handle correctly.
We work with hvac contractors throughout Michigan, including Detroit, Grand Rapids, Warren, Ann Arbor and Lansing.
What we build into your books
The three things that change first.
Seasonality that shows up in the numbers
Summer surplus and winter shortfall separated out, so you can see what a slow month actually costs and plan for it instead of absorbing it.
Maintenance agreement margins
Recurring agreement revenue tracked against what it costs to service. Most owners find they have been underpricing for years.
Install versus service
The two sides of the business carry very different margins. Split apart, they change how you quote.
HVAC clients
In their words.

I was doing books at the kitchen table at 11 at night after a full day of service calls. My wife finally told me it wasn't sustainable. First month ADB took over, they found $12,000 in expenses I'd never categorized right — parts, fuel, the works. I got my evenings back and I found out I'd been underpricing my maintenance agreements for two years.

In summer we're drowning, in winter we're wondering where the money went. Nobody I'd worked with before understood that rhythm. These guys built the books so I can actually see what my slow months cost me, and now I plan for them instead of panicking in February.

Honestly I said yes because the first month was free and I figured I'd get what I paid for. Then I got the report back and it was cleaner than anything my last bookkeeper sent me in 5 years. I signed on the same week.
