Heat recovery ventilation (MVHR) supplies fresh air and extracts stale air through a unit with a heat exchanger, which transfers much of the heat from the outgoing air to the incoming air.
Our coverage in Cardiff
In Cardiff, commercial premises range from city-centre office blocks and shopping streets to restaurants, hotels and industrial estates.

Things to check in Cardiff
Filters
Filters must be changed regularly to keep air flow and air quality up.
Roof and height work
Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.
Summer bypass
A bypass avoids warming incoming air in summer.
Neighbours and noise
Outdoor units near flats — common above shops — need careful siting so noise at neighbours' windows stays low. We choose positions and quieter units with that in mind.
Premises we work in around Cardiff
- Gyms and leisure: high-capacity cooling and fresh air for gym floors, studios and changing rooms.
- Hotels and hospitality: quiet bedroom units, public-area cooling and heat recovery for hotels.
- Schools and education: classroom cooling, ventilation and IT room cooling, installed in the holidays.
In Wales, systems holding 5 tonnes CO2 equivalent of refrigerant or more fall under GB F-gas rules, with regular leak checks and records; buildings with more than 12 kW of air conditioning in total also need a periodic energy inspection.
