What else we do in Thorley Street
How the visit works
The first job on site is protection: sheets over the floor and any furniture nearby and nothing is moved without asking you. Then the electrics are made safe and the work begins. The work on site takes anything from an hour or so to a full day, depending on the fault and the parts, and we clear up before we go. Somewhere like Thorley Street, it helps to know about lanes, gates and where to park.
- First, a few questions by phone or email about the brand, the fault and anything shown on the controller.
- The engineer reads the fault codes and checks the electrics, airflow, drain and refrigerant circuit.
- Nothing is repaired until you’ve heard what’s wrong and agreed a fixed price.
- The fix goes in, with any refrigerant work tested and written into the F-Gas records.
- We run the system, check it’s working properly and note anything else that needs attention.
Getting ready for the visit
- Let us know if the units are on a roof, a high wall or in a locked area
- Unlock any gate, garage or side passage we need
- Tell us about parking and loading

Landlords, agents and facilities managers
Under the GB F-gas rules, responsibility for leak checks is shared between whoever operates the equipment and the engineers who work on it. Where a building is let or managed, the lease or contract should make clear who looks after the system and we’re happy to deal with whoever it is.
Larger air conditioning systems in buildings need more than servicing: systems with an effective rated output over 12 kW need a TM44 inspection by an accredited energy assessor at least every 5 years. We arrange the inspection, get the system ready and put right anything it picks up.
When air con fails in Thorley Street
Twyford House, listed at grade II*, is one of roughly 14 protected buildings and structures in the half-mile around Thorley Street’s centre. For most visits that makes no difference. It only comes up when an outdoor unit has to be replaced on a protected building. About 76% of households live in detached or semi-detached houses, according to the last census (2021). Let us know where the outdoor unit sits and whether a ladder is needed to reach it.
A photo of the error code and the unit’s rating label helps us plan the repair.

What the work involves, system by system
Condensate drains and pumps
Most water leaks from indoor units come back to the condensate system. Blockages, kinks and failed pumps are the usual causes, and a unit that isn’t level can spill water too.
Refrigerant leaks
If the charge is low, there’s a leak somewhere. The leak is found and fixed, then the circuit is tested, evacuated and recharged and every step is recorded.
What we are called out for in Thorley Street
When ice forms on the pipes or coil, something else is wrong. It typically points to poor airflow, such as a clogged filter or a fan problem, or to a refrigerant leak. Switch the system off and let it thaw before calling us.
Most people get in touch after spotting one of these:
- Rattling, buzzing or grinding noises
- A unit blowing warm air
- Ice on the pipework or the coil
For a school like Thorley Hill Primary School, urgent repairs can be booked right away and bigger work in the holidays.
