Control Service Center

What Control Service Center does

Control Service Center, Inc. (CSC) is a family-owned commercial HVAC service company founded in 1981 in Boulder, Colorado and headquartered at 826 South Sherman Street, Longmont, CO. The company provides heating, ventilation, and air conditioning maintenance, repair, replacement, and installation services to commercial property owners, property managers, and general contractors in Boulder County and surrounding Colorado areas. Service coverage spans HVAC repair, preventive maintenance, building automation controls (notably Carrier Open and Carrier VVT Generation II/III), controls retrofits, ductwork fabrication, hydronic and boiler systems, zoning controls, air purification, and commercial tenant finish work.

The technical core of the business is building automation controls integration, anchored by CSC's status as the only local contractor certified on the Carrier Open format at both the CS (hardware) and IS (software) levels, and as a Carrier Commercial Expert since 2019. CSC supplies, installs, and services equipment across multiple OEMs including Carrier, Trane, Lennox, York, Rheem, Mitsubishi, Johnson Controls, and Honeywell, and operates 24-hour emergency dispatch with sub-two-hour response times. The company also offers remote monitoring capabilities for commercial properties and preventive maintenance programs with discounted labor rates.

CSC's commercial model is a direct field-service operation: hourly-billed repair and installation work with transparent invoicing (no trip charges, fuel surcharges, or markups) layered with annual preventive maintenance subscriptions and free estimates. There are no commissioned sales staff; client engagement is owner-operated, primarily by the Strouse family (Jim Strouse, President Brandon Strouse, and Vice President Kyle Strouse). Customer acquisition is largely referral- and reputation-driven, supported by long-tenured enterprise relationships — several anchor clients, including W.W. Reynolds Companies, have relied on CSC for two to three decades. CSC reports 11–50 employees and does not disclose revenue.
