HVAC business due diligence guide

Financial records that tell one consistent story.

• Annual tax returns and financial statements, current year-to-date results, and monthly comparisons.
• Balance sheet, debt schedule, accounts receivable and payable aging, and bank reconciliations.
• Support for owner compensation, related-party transactions and each proposed earnings adjustment.
• Revenue and margins by service line, location and customer segment.
• Project accounting, work in progress, deposits and deferred maintenance-plan obligations.

Discrepancies between tax returns, internal statements and your marketing summary need explanation before a buyer discovers them. Your CPA can help reconcile the records.

Customers, maintenance agreements and projects.

• Largest customer concentrations and contract terms.
• Maintenance agreement roster, renewals, cancellations and required services.
• Backlog, estimates, open projects and job-level profitability.
• Warranty commitments, callbacks and material disputes.
• Marketing spend, referral sources and ownership of customer records.

Aggregate or anonymize records early where possible. Customer-level disclosure should follow an agreed confidentiality and diligence plan.

People and the work the owner does.

• Organization chart, management roles and the owner’s actual responsibilities.
• Employee roster, compensation, benefits and contractor arrangements.
• Relevant technical qualifications and applicable licenses.
• Employment agreements, restrictive covenants and key-person retention considerations.
• Dispatch, estimating, purchasing, safety and service procedures.

Identify who holds each license and what the transaction may require in the relevant jurisdiction. Do not assume a license transfers with the company. Verify the facts with the appropriate regulator and counsel.

Fleet, equipment, property and obligations.

• Truck and equipment schedules, condition, ownership, financing and liens.
• Inventory lists and obsolete or slow-moving items.
• Facility leases, owned real estate and assignment provisions.
• Insurance, claims, disputes and material contracts.
• Software subscriptions, data access and vendor relationships.

The sale agreement needs to specify what transfers and what remains. Ask how tools, vehicles, inventory, receivables and working capital are treated. Real estate may need a separate agreement or lease.

Share information in stages.

Discuss buyer qualification and confidentiality agreements before giving access to identifying or sensitive records. Use appropriate access controls and keep track of what has been shared. Avoid uploading customer lists, employee details or tax returns into an initial website inquiry.

For a competitor, discuss additional safeguards with your attorney. A confidentiality agreement alone does not eliminate every risk.

Plan the transition while diligence is underway.

Clarify communications, employee onboarding, systems, customer service, license requirements and the owner’s agreed support. Distinguish the purchase conditions from the practical work that happens on day one.

Taxes and allocation should be reviewed before documents are final. Form 8594 can apply to qualifying business asset transfers; it is not a filing required for every type of sale. IRS Form 8594 guidance
