Air conditioning repair in Park Street
A sealed system shouldn’t lose refrigerant, so a low charge means a leak somewhere. Simply adding gas means it will leak away again. We locate the leak, repair it, test, evacuate and recharge and write it up in the F-Gas records. The work covers multi-split systems, ducted systems and wall-mounted split systems, and people most often call us about ice forming on the indoor unit or pipes and water dripping from the indoor unit.
In a village like Park Street, most air conditioning we repair is in homes, garden rooms and the occasional pub or village business. Describe the fault and send a photo of the unit’s label so we can plan the visit.
The records are your system’s health record: what was fitted or found, what was done and when. If anything goes wrong later, it helps the next engineer and the manufacturer and it’s worth keeping safe.

Air conditioning repair in Park Street: the local picture
Park Street’s centre falls inside the Park Street and Frogmore Conservation Area. On the National Heritage List, around 18 entries fall within 0.5 miles of the middle of Park Street; Toll Cottage (grade II) is one. We keep it in mind in case a new outdoor unit is ever needed, as protected buildings can need consent for that. About 40% of homes across Park Street and its surrounding area date from 1945 to 1972, according to VOA council tax data, and about 62% 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.
If a system fails at a school such as Park Street Church of England Voluntary Aided Primary School, our 24/7 line takes the call, and planned repairs can wait for the holidays.

Common reasons people call us are:
- A system that keeps cutting out
- Weak airflow from the indoor unit

Questions to ask before booking
- Whether the electrical work is done by a registered contractor, such as NICEIC approved
- Which brand and model they’re proposing, and why
- What records you get at the end
What happens on the day
Think of the visit in three stages: look, put right and sign off. First we check the system or the space against the plan, then we do the work, and finally we test, record and explain. Most of the time goes on the middle part, and that takes a single visit for many faults, while some repairs need a second visit once parts arrive. A note on how to find the property and where to park makes a visit to Park Street easier.
- Describe the problem and the brand, and mention any code on the display.
- On the diagnosis visit, we test the electrics, airflow, drain and refrigerant.
- We explain the cause in plain English and give you a fixed price.
- Once you’re happy, the repair is done and any refrigerant work recorded.
- The system is run and checked, and you get a written note of the repair.
Before we arrive
- Name a contact who can meet us at the agreed time
- Make sure we can reach the consumer unit or fuse board
- Unlock any gate, garage or side passage we need
Getting a price
Quoting starts with a diagnosis, either on a site survey or, for simple jobs, from your photos and details. Then you get a fixed price so you know the cost before we begin.

What the work involves, system by system
Refrigerant leaks
A low refrigerant charge always means a leak. We find it, repair it, pressure test the circuit, evacuate it and recharge to the manufacturer’s charge, and the work is recorded in the F-Gas records.
Fans and compressors
Fans are the moving parts most likely to wear, and the first sign is often noise or weak airflow. Indoor and outdoor fan motors can usually be replaced, depending on parts availability.
Why deal with it now?
Refrigerant supply is changing. Repairing and recharging existing R410A systems is still legal, but R410A is getting scarcer and dearer to buy as the GB phase-down tightens, so for older systems we compare the cost of a repair with a replacement. An early booking makes the visit to Park Street easier to arrange.
What you pay depends on the system and the number of rooms or units, how easy the units are to reach and the parts and time the job needs. We give you a fixed price before we start, so you know where you stand.
