Chiller Plants & Central Cooling
Water-cooled centrifugal chiller installation and service, plus shell-and-tube tube cleaning that keeps central plants running efficiently.
Water-Cooled Centrifugal Chiller Installation
- Challenge
- A central plant needed dependable, high-capacity cooling sized for South Florida's year-round latent loads.
- Solution
- Set and connected a Trane water-cooled centrifugal chiller with new front piping, then verified flow and operating conditions.
- Outcome
- A clean, serviceable mechanical-room layout built for long-term reliability and straightforward future maintenance.
Centrifugal Chiller Service & Mechanical-Room Access
- Challenge
- An operating chiller required service access and a thorough operational review to protect plant uptime.
- Solution
- Performed side-access service and inspection on the centrifugal chiller, confirming controls, piping and operation.
- Outcome
- Documented, well-organized equipment that supports planned maintenance and reduces avoidable breakdowns.
Shell-and-Tube Heat Exchanger Tube Cleaning
- Challenge
- Fouled condenser tubes were reducing heat-transfer efficiency on a shell-and-tube heat exchanger.
- Solution
- Mechanically cleaned the shell-and-tube bundle as part of scheduled chiller maintenance to restore heat-rejection performance.
- Outcome
- Restored heat transfer and a cleaner running plant - captured on video below as part of our maintenance workflow.
VRF / VRV Systems
Our signature specialty - factory-certified VRF outdoor banks, ceiling cassettes and ducted indoor units installed for efficient, zoned comfort.
Mitsubishi CITY MULTI VRF Outdoor Bank
- Challenge
- A building needed efficient zoned cooling with room for technicians to commission and service the system.
- Solution
- Installed and arranged a bank of Mitsubishi CITY MULTI VRF outdoor units with proper clearances for commissioning access.
- Outcome
- Right-sized, factory-certified VRF capacity laid out for safe, repeatable service throughout the equipment's life.
Ceiling-Cassette VRF Indoor Unit
- Challenge
- Occupied interior space called for discreet, even air distribution without disrupting the existing ceiling.
- Solution
- Integrated a Trane ceiling-cassette VRF indoor unit cleanly into the T-bar ceiling grid.
- Outcome
- Quiet, evenly distributed comfort with a finished look that blends into the occupied space.
Ducted VRF Indoor Unit
- Challenge
- A zone required concealed ducted distribution tied into the building's VRF system.
- Solution
- Configured a Mitsubishi CITY MULTI PEFY ducted indoor unit for concealed, ducted air delivery.
- Outcome
- Flexible, concealed comfort delivery that keeps finished spaces clean while staying fully serviceable.
Controls, Commissioning & Diagnostics
Touchscreen controllers, live commissioning with manufacturer software, and calibrated field diagnostics that prove performance.
VRF Touchscreen Controller Setup
- Challenge
- Building staff needed clear, central control and visibility over a multi-zone VRF system.
- Solution
- Configured a TE200 VRF touchscreen controller for centralized scheduling and zone management.
- Outcome
- Intuitive day-to-day control that helps staff manage comfort and operation without a service call.
Live Commissioning & Refrigerant Charge
- Challenge
- A new VRF system needed verified refrigerant charge and confirmed operating parameters before handover.
- Solution
- Commissioned the system live using manufacturer software and gauges to verify charge and operating data.
- Outcome
- A system handed over with documented commissioning data - supporting warranty and reliable performance.
Evaporator Temperature Diagnostics
- Challenge
- Confirming real-world cooling performance required precise field measurement, not assumptions.
- Solution
- Took evaporator temperature readings with calibrated instruments to validate system operation.
- Outcome
- Measured, data-backed verification that the equipment is performing as designed in the field.
Air Handling & Mechanical Rooms
Air handlers, fan-coil electrical integration and insulated ductwork - the mechanical-room work that ties a commercial building together.
Air Handler & Fan-Coil Electrical Integration
- Challenge
- An above-ceiling air handler required clean, code-conscious electrical integration in tight space.
- Solution
- Installed the fan-coil air handler with an organized electrical box and connections above the ceiling.
- Outcome
- A tidy, accessible above-ceiling install that keeps wiring serviceable and the occupied space clean.
Insulated Ductwork & Mechanical-Room Buildout
- Challenge
- A mechanical room under construction needed coordinated overhead ductwork and supporting infrastructure.
- Solution
- Routed insulated overhead ductwork alongside cable tray with careful trade coordination during the buildout.
- Outcome
- An organized, well-coordinated mechanical room ready for reliable long-term operation.
Why These Projects Look Different
