We record what is installed, its condition and refrigerant, and what can be re-used.

Local points to consider
Downtime
We schedule the swap to keep the space usable, often over a weekend.
Conservation areas
Historic streets and listed buildings in and around Watford are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Disposal
Old refrigerant must be recovered by certified engineers and the units disposed of as waste electrical equipment.
Working hours
Most Watford businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.

Can existing pipework be re-used?
Often, if it is the right size, in good condition and compatible with the new refrigerant. We test and flush it before relying on it.
Is it illegal to use R22 air conditioning?
No — you can keep running an R22 system, but it cannot be maintained with virgin or recycled R22, so most repairs involving the refrigerant circuit are no longer possible.
