Commercial HVAC Maintenance, Repair & Installation Services

Large commercial buildings rely on complex mechanical systems that must run reliably every day. Commercial Tech, Inc. installs, repairs, and maintains commercial HVAC systems for office buildings, schools, hospitals, government facilities, data centers, and multi-tenant properties throughout Northern Virginia, Maryland, and Washington, D.C.

Central Plants and Large Systems

• Air-cooled and water-cooled chillers, including centrifugal and screw chillers
• Cooling towers and condenser water systems
• Commercial boilers and hydronic heating plants
• Air handling units and VAV systems
• Packaged rooftop units for large buildings
• Data center and computer room cooling

We service chillers and large equipment from Carrier, Trane, Daikin, and York, along with other major manufacturers.

Building Automation and Controls

A building automation system (BAS) ties chillers, boilers, air handlers, and terminal units together. We troubleshoot controls, replace sensors and actuators, adjust sequences, and help building engineers get more out of existing systems. Optimized schedules and setpoints can noticeably reduce energy use.

• Planned preventive maintenance programs with written reports
• Emergency repair service
• Chiller and cooling tower startups and seasonal changeovers

Frequently Asked Questions

Do you work in occupied buildings?

Yes. We schedule work to minimize disruption, including after-hours and weekend shifts when needed.

Can you take over maintenance from another contractor?

Yes. We start with an inspection of your equipment, document its condition, and build a maintenance schedule from there.

How often should a chiller be serviced?

Chillers should have routine operating checks throughout the season and a full annual inspection, which includes oil and refrigerant analysis, tube inspection, and controls checks. Cooling towers need regular cleaning and water treatment.
