Points to plan for in Harrow
R22
Since 1 January 2015, R22 systems cannot be maintained using virgin or recycled R22. If one leaks, the practical fix is usually replacement.
Working hours
Most Harrow businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Downtime
We schedule the swap to keep the space usable, often over a weekend.
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.
