Controls & automation that think ahead
Well-installed equipment still wastes energy if its controls are wrong. Building automation ties heating, cooling and ventilation together and runs them on schedules, set points and real conditions in the space.
Bharat Mechanical Corp. installs and integrates direct digital controls (DDC), connects new equipment to existing building automation systems, and replaces outdated pneumatic controls with modern digital ones.
We check every point, verify the sequences of operation with the engineer and controls vendor, and train building staff on how to use the system day to day. Good controls are one of the most direct ways to cut energy use under NYC's Local Law 97.
Scope of Work
This service can be contracted on its own or as part of a complete mechanical and construction package.

- Variable frequency drivesVFDs on fans and pumps to match output to demand.
- Sequences of operationImplementing and verifying the engineer's control sequences.
- Trends & alarmsSetting up trending, alarms and graphics so staff can see what is happening.
- Checkout & trainingPoint-to-point checkout, functional testing support and owner training.
Systems & Equipment
How We Deliver
Survey & Scope
We walk the site, review drawings and existing conditions, and confirm exactly what the job includes.
Clear Proposal
An itemized price and schedule, with value-engineering options where they make sense.
Coordinated Install
Submittals approved, trades coordinated and experienced crews on site with a supervisor accountable for the work.
Point checkout & functional testing
Every input and output is checked end to end, then sequences are tested with the commissioning agent.
On the Job
Why Choose Bharat Mechanical
Mechanical and controls together
The team that installs the equipment also understands how it should be controlled.
Energy savings you can see
Schedules, resets and trends that show where energy is going.
Staff who can run it
Clear training and documentation so the system is used, not overridden.
Frequently Asked Questions
Can you add new equipment to our existing building automation system?+
Yes. We integrate new equipment into existing systems where the protocol and platform allow, and advise when an upgrade is the better option.
What is the benefit of replacing pneumatic controls?+
Digital controls are more accurate, easier to adjust and can be monitored remotely. They also allow energy-saving strategies such as scheduling, set-point resets and demand-controlled ventilation.
How do controls help with Local Law 97?+
Controls reduce run time and match equipment output to actual demand, which lowers energy use and emissions. Retro-commissioning under Local Law 87 often identifies control fixes as the quickest savings.
Do you provide training after installation?+
Yes. We walk building staff through the system, the main screens and alarms, and provide documentation at turnover.
