Executive summary
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%. Taken together, these numbers give a factual snapshot of the business.
StocksXray gives Comfort Systems Usa Inc an X-Ray Score of 52 out of 100 (high confidence), ahead of 54% of the S&P 500 stocks in its sector. Its strongest lens is financial health (74) and its weakest is valuation (20).
Our fair value blend is $370.40 (range $360.96 to $380.26). At $1,439.07 the stock trades 289% above that blend, so the label is "Overvalued" with high model uncertainty. Fair value is a range, not a price target.

Every number comes from SEC filings, end-of-day prices and the StocksXray models described on the methodology page. The X-Ray Score ranks each metric against the company's own sector. Fair value blends three models and carries a typical error of about 40%, so treat it as a range. Analyst ratings, price targets and earnings-call summaries are not part of this report.
