How a visit in Stevenage works

  1. Protect

    Floors and furniture are covered and the unit isolated.

  2. Strip down

    Covers, filters and (where practical) the fan are removed for cleaning.

  3. Clean

    Coils, fan, tray and drain are cleaned and rinsed into a collection bag.

  4. Test

    The unit is reassembled and run, with temperatures checked.

Local points to consider

Downtime

Each unit is out of action for about an hour while it is cleaned.

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.

Smells

Musty smells usually mean biological growth in the coil or tray; a deep clean and drain treatment normally cures them.

Leased premises

If your Stevenage premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.

Types of premises we cover in Stevenage

Compliance in England: refrigerant work falls under GB F-gas rules, and buildings with more than 12 kW of air conditioning in total need a periodic energy inspection (often called TM44).
