Your Equipment May Not Be the Problem. Your Controls May Be.

MODERNIZE YOUR SYSTEM WITHOUT AUTOMATICALLY REPLACING EVERYTHING

Repair & Upgrade

Many commercial buildings rely on HVAC and mechanical systems that are still capable of doing their job but are being managed by outdated, limited or poorly functioning controls.

IDM also provides commercial plumbing repair, retrofitting and system upgrades.

Our commercial plumbing capabilities allow clients to work with one contractor for both building controls and the mechanical equipment those controls may monitor or operate.

Commercial HVAC Repair and Retrofitting

IDM diagnoses and repairs commercial heating, cooling and ventilation systems with a repair-first approach. When equipment remains serviceable, we look for opportunities to restore performance or improve how it is controlled before recommending complete replacement.

BAS Controls Retrofitting and Upgrades

An aging BAS does not always require a complete tear-out.

IDM can evaluate existing controllers, wiring, sensors, equipment and network infrastructure to determine which components may be retained and which should be upgraded.

BUILDING AUTOMATION SYSTEM SERVICES

A Building Automation System, commonly called a BAS, provides centralized monitoring and control of compatible building equipment.

Instead of relying entirely on individual thermostats, disconnected controllers or manual adjustments, a properly designed BAS can give building operators a clearer view of how their systems are performing.

BAS Installation

For buildings without centralized controls, IDM can design and install a BAS solution based on the property’s equipment, operating requirements and budget.

A new BAS can bring compatible systems into a more organized interface, giving authorized personnel improved visibility into building conditions and equipment operation.

Open-Protocol and Open-Source Control Options

Some building-control systems are built around proprietary software, hardware or service tools that can make future changes difficult or expensive.

Where appropriate for the application, IDM can explore open-protocol, open-platform and open-source control options that provide greater flexibility in how your building systems are connected, monitored and maintained.

KEEP THE EQUIPMENT. UPGRADE THE INTELLIGENCE.

Replacing an entire commercial HVAC system can require a major capital investment. In some buildings, the better solution is to improve how the existing equipment is controlled.

Modern controls may allow compatible equipment to operate according to actual occupancy, demand, schedules and building conditions.

Results depend on the condition, design and operation of each building. IDM begins with an evaluation so you can understand the available options before making a major investment.
