About TDC
Thermal Distribution and Control, done properly
TDC is a commercial HVAC and mechanical services contractor working nationwide from operating centres in Chester and Leeds, across installation, maintenance and 24/7 response.
Engineering first
Our advice comes from engineers who work on plant, not from a sales script. If replacing is cheaper than repairing, we'll say so.
Compliance as standard
F-Gas, CDM, HS&E and statutory testing are built into how we deliver work — with the paperwork to prove it.
Long-term relationships
Named account managers and consistent engineering teams mean the people attending your site already know it.
How we're structured
Two divisions, one accountable team
Our projects division handles design and installation; our service division handles maintenance and reactive works. Both share the same engineers, systems and site knowledge.
- In-house design and project management
- Directly employed engineering teams
- Nationwide coverage from Chester and Leeds
- Manufacturer-approved installation, including Samsung
