Valuation

How Commercial HVAC Businesses Are Valued

A clear explanation of how multiples work and what drives your number.

The SDE Method

Most Commercial HVAC businesses under $5M in revenue are valued using Seller's Discretionary Earnings (SDE). SDE represents the total financial benefit to a single working owner - essentially, net profit plus owner salary, personal expenses run through the business, depreciation, and one-time costs.

Once SDE is calculated, it's multiplied by an industry-specific multiple (typically 3.0x to 5.0x for Commercial HVAC) to arrive at an estimated business value.

What About EBITDA?

EBITDA is typically used for larger businesses ($5M+ revenue) with absentee ownership. Unlike SDE, it does not add back the owner's salary.

Example Valuation

Annual Revenue$3,000,000
Net Profit (tax return)$350,000
+ Owner Salary$180,000
+ Personal Expenses$50,000
+ Depreciation$70,000
= Adjusted SDE$650,000
