HALO HVAC Mechanical and Electrical HVAC Services

HALO HVAC ensure energy efficiency and future adaptability. With seamless integration into Building Management Systems (BMS) our HVAC services provide centralized control guaranteeing a smart, sustainable solution for evolving control needs. 

EC Fan Upgrades 


Switching to EC fan arrays enhances efficiency, resulting in significant energy and CO2 savings. These fans also provide redundancy in multi-fan setups and require easy maintenance without traditional components like belts and pulleys.

Replacing or repairing dampers and actuators in damaged areas ensures the restoration of airflow set-points while minimizing pressure drop.



Replacing worn or damaged coils is essential for restoring optimal performance. Over time, changes in set point parameters may necessitate the installation of new coils that are heat pump ready.

Filters & Air Treatment

HALO HVAC Mechanical and Electrical HVAC Services

Upgrading your filters and housings in line with ISO 16890 can significantly improve IAQ, system pressure drop, and energy consumption, reflecting a commitment to advanced technologies and overall system efficiency.

Clean Room & Labs, Chandlers Ford 

13 Air Handling Units serving a critical manufacturing process and science laboratories, all requiring refurbishments, controls and BMS modifications, delivered in a specific time frame, whilst achieving 26t a year CO2e reduction.

5 Star Hotel, Knightsbridge, London

The belt driven fans within the air handling units at this hotel had failed, resulting in no ventilation to several areas of the building including the toilets and the kitchen. It was imperative that the ventilation was reinstated as a matter of urgency to ensure the Hotel was fully operational & compliant.

Offices. Gracechurch Street, London 

With the building owners advertising for new leases a key objective was to ensure the indoor environment is comfortable and healthy. Over time, the existing AHUs became less efficient, leading to higher energy bills and reduced indoor air quality.
