Comfort Systems USA provides mechanical, electrical and plumbing contracting services, including the installation and maintenance of heating, cooling, ventilation and related systems. Its subsidiaries work on commercial, industrial and institutional buildings such as data centres, hospitals, factories and offices. Revenue comes from construction projects, which are recorded as work progresses, and from recurring service contracts, so backlog and project timing affect reported results.
Trailing twelve-month revenue stands at $4.0 billion, while revenue fell by 23.8% a year over the past three years. Return on invested capital is 30%, alongside an operating margin of 18.8%. Net debt to EBITDA sits at -2.0 times, a sign of more cash than debt. The company pays a dividend, and the yield is 0.2%. On the X-Ray Score, it is rated 52 out of 100. Taken together, these numbers give a factual snapshot of the business.

Debt = borrowings plus lease liabilities. Cash & securities = cash, equivalents and short-term marketable securities (long-term securities are not counted, so net cash can be understated for companies that hold large long-term investments). Net debt = debt minus cash & securities. Source: latest SEC 10-Q/10-K. EBIT / EV yield = operating profit divided by market cap plus net debt.
Fair value estimate
$800middle half of models $651 – $843
Overvalued−37.4% to fair value
Average of the 10 valuation models that pass our checks: multiples, discounted cash flow, dividend discount and earnings power value. A model more than 100% above or 60% below the price is left out as unrealistic. Model uncertainty is High, based on how far apart the models are. Undervalued or Overvalued means the gap to fair value is more than 17.5%.
Peak-cycle earnings: the current operating margin is more than 1.5x its 7-year average, so multiples applied to today's profit may overstate value; model uncertainty is set to High
A model estimate, not a price target or recommendation. Inputs: risk-free 5.13%, equity risk premium 4.30% (Damodaran). How it works.
What this means
Average business, priced high
Our models put fair value below today's price, so a lot of good news may already be in the price. A high score does not guarantee a good outcome; it shifts the odds a little. Use the checklist as a prompt for your own research.

Sector leaders: highest X-Ray Score in Industrials
FIX ranks #37 of 81 in Industrials and #2 of 4 in Construction & Engineering by X-Ray Score. A higher score is stronger on our five pillars; it is a ranking of facts, not a forecast.
Green means better than the peer median, red worse (only where a higher or lower figure is clearly better). A dash means too few companies report the figure. P/E, EV/EBITDA and price changes are not graded: a different level is not good or bad by itself.

These ratings compare companies with each other and describe the past; they are not a forecast, a recommendation or part of the X-Ray Score. A factor is left out when its data is missing or meaningless (for example a P/E on negative earnings). A dash in the history columns means fewer than three usable years.

Signals describe what the chart is doing, not what to do. Moving averages: price above the average is bullish. Oscillators use the usual thresholds (RSI 30/70, Stochastic 20/80, CCI ±100, Williams %R −80/−20; MACD and momentum above zero are bullish). Weekly and monthly views use closing prices only.
