Local points to consider
Hygiene
Drip trays and coils must be kept clean to avoid biological growth.
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.
Energy
Fan upgrades and better controls can cut energy use significantly on older units.
Conservation areas
Historic streets and listed buildings in and around Blackburn are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Typical premises in Blackburn
- Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.
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).
