Ventilation Systems
Ventilation and air conditioning keep the air in a building fresh, comfortable and safe. Mechanical ventilation supplies outdoor air and removes stale air, smoke, fumes and moisture; extract systems serve kitchens, toilets, car parks and plant rooms; and air conditioning controls temperature and humidity in offices, wards, hotel rooms and server rooms.
Trident Plumbers Limited offers services related to climate control and indoor air quality, from air conditioning installation to the design and installation of ventilation systems and their maintenance. We install these systems alongside plumbing, drainage and fire fighting, so ductwork and pipework are coordinated in the ceiling void. See examples of our mechanical ventilation and air conditioning work on our projects page.

Typical buildings
Standards and good practice
We install to the project specification and the codes it calls up. On ventilation and air conditioning work these commonly include:
- ASHRAE 62.1
- Ventilation and acceptable indoor air quality
- CIBSE Guide B
- Heating, ventilating, air conditioning and refrigeration
- SMACNA
- HVAC duct construction standards (metal and flexible)
- Manufacturer requirements
- Installation, refrigerant charging and commissioning instructions for the equipment supplied
The governing standards are set by the project’s mechanical consultant and the local authority; we install to them and provide the commissioning records.
How we work
A clear process, start to finish
Brief and site visit
We review your drawings, specification or bill of quantities and, where needed, visit the site to understand the building and how it will be used.
Design and proposal
We size the system, select equipment to the specification and give you a clear, itemised quotation.
Approvals and procurement
Shop drawings and material submittals go to the consultant for approval before materials are ordered.
Installation
Our own crews install the works, coordinated with the main contractor and the other trades on site.
Testing and commissioning
Every system is tested and commissioned, with results recorded and witnessed by the client or consultant.
Handover and aftercare
As-built drawings, operation and maintenance information and training for your team, followed by maintenance when you need it.

FAQ
Ventilation Systems: common questions
Yes. We install mechanical ventilation, extract systems and air conditioning, and coordinate them with the plumbing, drainage and fire fighting services in the same building.
Yes. We install kitchen extract canopies, ductwork and fans to the specification, with access for cleaning and the make-up air the kitchen needs.
Without balancing, some rooms get too much air and others too little. Measuring and adjusting airflows at each grille and diffuser makes the system deliver what it was designed for.
Yes. We service filters, coils, drains, fans and refrigerant circuits and repair faults, for systems we installed and for existing systems.
