Air conditioning chart of accounts

Air conditioning and heating work mixes costly installs with ongoing service work, and each runs through the books in its own way. This chart adds accounts for install deposits, service agreements paid ahead, refrigerant and the other costs of the trade to the general chart.

What this industry adds

  • When a homeowner pays a deposit before a split or ducted system goes in, Installation deposits received holds it against that install.
  • When a client pays for scheduled maintenance visits before they are made, Service agreement payments in advance holds that money against the visits still due.
  • Units and parts for jobs holds the equipment bought for a particular install or repair. Refrigerant purchases has a line of its own, since gas goes into new installs, services and regas jobs alike.
  • Some jobs need help from outside the trade: Electrical subcontractors for new circuits and power connections, and Crane and lifting hire for getting heavy or rooftop units into place.
  • Refrigerant and electrical licence fees records what the business pays for its technicians' refrigerant handling and electrical licences.

What goes in each column

  • Code: A number that sorts the account into its group: 1 for assets, 2 for liabilities, 3 for equity, 4 for income, and 5 and 6 for expenses.
  • Account name: The name that appears in your books and reports.
  • Type: Asset, Liability, Equity, Income or Expense, which decides whether the account appears on the balance sheet or the profit and loss statement.
  • What goes in it: The transactions to record against the account.

How to use it

  1. Record each install deposit in Installation deposits received with the customer's quote number, so it can be matched to the final invoice. Ask your accountant how deposits should move into income.
  2. If service clients pay ahead, keep a list of what each has paid and the visits still due, and check it against Service agreement payments in advance when you reconcile.
  3. Charge units, parts and refrigerant to the install or service job they went into, so each job's materials can be read against its quote.
  4. Refrigerant purchases is for the gas alone: recovery units, vacuum pumps and gauges stay in the general Equipment account.
  5. Use these accounts for the firm's own money from installs and servicing. Your accountant can tell you if the way the business is structured needs others.
