How it works in Hounslow
Survey
We record what is installed, its condition and refrigerant, and what can be re-used.
Plan the swap
Removal and installation are scheduled to keep downtime short.
Recover and remove

Install and commission
New units are fitted, tested and commissioned with fresh records.
Local points to consider
Disposal
Old refrigerant must be recovered by certified engineers and the units disposed of as waste electrical equipment.
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.
Downtime
We schedule the swap to keep the space usable, often over a weekend.
Access and parking
Town-centre jobs in Hounslow often come down to access — loading restrictions, parking for the van and getting equipment onto a roof. We check this at survey and plan deliveries around it.
