Analysis
Comfort Systems USA, Inc (FIX) currently trades at $1,728, while our model-based Fair Value estimate is $519.97, implying the stock looks roughly 69.9% overvalued today. The Quality Score stands at 71/100 (solid quality), in the Industrials sector. Bear case: priced above our estimate, the market already discounts strong expectations. Bull case: above-average quality can justify a premium, the entry price still matters most (evidence: high).
Over the trailing twelve months, Comfort Systems USA, Inc generated revenue of $10.1B at a net margin of 12.1%. Revenue grew 1.0% year over year. It earns a return on equity of 53.3%. The balance sheet holds a net cash position of $196M. Fundamentals as of Aug 13, 2026
Our scenario range runs from $358.49 (bear case) to $765.61 (bull case); at $1,728, the current price sits above that range. Bear and bull are the same models run on conservative and optimistic assumptions (margins, growth, valuation multiples), so a plausible valuation range, not a price target. The share trades about 17% below its 52-week high and 269% above its 52-week low, currently above its 200-day average. For context, the median of 10 Industrials peers we cover trades at -34% fair-value upside, at -70%, FIX screens richer than that median.
Fair Value models
Each model estimates fair value its own way; the Fair Value above is the evidence-weighted blend. Evidence (0–100) measures how completely this model’s inputs are available: well-fed models carry more weight in the blend. The spread across models is intentional, each one stresses a different value driver; dividend models, for instance, come out structurally low when payout is small.
All 26 models by family
Widest divergence: DCF Models ($694.72) versus Dividend Discount ($31.49). Highest evidence: Growth DCF (80).
