The company offers heating, ventilation, and air conditioning systems, as well as plumbing, electrical, piping and controls, off-site construction, monitoring, and fire protection. It also involved in the design, engineering, integration, installation, and start-up of mechanical, electrical, and plumbing (MEP) and related systems in new buildings; and renovation, expansion, maintenance, monitoring, repair, and replacement of MEP systems in existing buildings. In addition, the company provides remote monitoring of power usage, temperature, pressure, humidity and air flow for MEP and other building systems.

Comfort Systems USA, Inc. was founded in 1917 and is headquartered in Houston, Texas.
Comfort Systems installs, repairs, and maintains HVAC, plumbing, and electrical systems in commercial and industrial buildings, earning project and service fees across the US. The business blends lumpy new-construction revenue with a growing recurring service-and-maintenance base, and is now adding modular manufacturing to reinforce its cost position.
Operating margin of 17% is earned by bidding and delivering complex mechanical and electrical projects with skilled crews, while the service-and-maintenance base adds a recurring, higher-visibility revenue layer that steadies earnings between construction peaks.
Business quality (Mixed): Solid 17% operating margin and a visible service-and-maintenance annuity give the business more predictability than a pure contractor, but the 48x P/E prices in sustained outperformance that the lumpy construction cycle does not guarantee.
Valuation: At 48× earnings, FIX trades 104% above the Construction average (23×).
