How it works in Walthamstow

Local points to consider
Summer bypass
A bypass avoids warming incoming air in summer.
Working hours
Most Walthamstow businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Integration
Heat recovery pairs well with air conditioning, which handles the room heating and cooling.
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 Walthamstow
- Schools and education: classroom cooling, ventilation and IT room cooling, installed in the holidays.
- Hotels and hospitality: quiet bedroom units, public-area cooling and heat recovery for hotels.

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).
