Things to check in Portsmouth
R22
Since 1 January 2015, R22 systems cannot be maintained using virgin or recycled R22. If one leaks, the practical fix is usually replacement.
Access and parking
Town-centre jobs in Portsmouth 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.
Pipe re-use
Re-use depends on pipe size, condition, cleanliness and the new refrigerant. We test before relying on it.
Working hours
Most Portsmouth businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.

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.
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.
