How we work in County Londonderry
Measure
We measure the opening and check wind exposure and existing heating.

The right width, air velocity and heat source are chosen.

Set up
Door contacts and controls are set so it runs only when needed.
What to think about in County Londonderry
Heat source
Heat pump air curtains are usually cheaper to run than electric ones.
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.
Exposure
Windy entrances need more powerful units or a lobby.
Working hours
Most County Londonderry businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
