Air conditioning servicing for homes and businesses in Park Street
A service is not the same as a regas. Refrigerant runs in a sealed circuit and shouldn’t need adding to. Where the checks suggest gas has been lost, the right step is to find the leak, and we will set out how. We’re often asked to deal with a system that struggles to cool on warm days and condensate leaking into the room, across ducted systems, wall-mounted split systems and ceiling cassettes.
We plan the trip to Park Street and can service more than one unit in one visit, which keeps it simple.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we explain those terms on your quote. Each brand sets its own conditions, so we go through them with you rather than leave you to find the small print.

What we do, step by step
There’s very little for you to do on the day. Just let us in and point us to the units, or to where they’ll be fitted, and the rest is down to us. Before we leave, the area is tidied and we explain what we have done. Visits to Park Street are agreed with you in advance and planned so the job can be finished in one trip where possible.
- We ask about the system: the make, the number of indoor units and any problems you’ve noticed.
- On arrival, a quick performance check shows how well it’s working before the clean.
- Dust and grime come off the filters and coils, and the drain is flushed so water runs away properly.
- Next come the terminals, the controller and the refrigerant side, with a leak check if the system’s size makes one a legal duty.
- A service record follows, with any faults and the options for fixing them.
How to prepare
- Make sure we can reach the outdoor unit, or where it will go
- Clear access to the fuse board
- Let us know if the units are on a roof, a high wall or in a locked area

Common questions in Park Street
How often should air conditioning in Park Street be serviced?
Once a year suits most home systems. Larger systems holding 5 tonnes CO2 equivalent or more also need a leak check at least every 12 months under the F-gas rules.
Do you cover Park Street for air conditioning servicing?
We do: Park Street falls inside our working area. Get in touch with the details and we reply the same working day.
Which accreditations do you hold?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, plus Checkatrade membership. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
What’s included in an air conditioning service?
The service covers the indoor units and the outdoor unit: filters, coils, drains and fans, then the electrics, the controls and how the refrigerant circuit is performing. A service record follows.
Can you set up regular servicing?
Yes. Send details of the systems and how they’re used and we will propose a schedule and quote for it. Leak checks required by the F-gas rules can be built in for larger systems.
When is an F-gas leak check required?
Only if the system is at or above the threshold of 5 tCO2e. Plenty of small splits sit under it, as 3 kg of R32 works out at about 2.0 tCO2e. We check the label and tell you whether your system needs checks and how often.
Is there a survey before the work?
Yes. We always look before we price, either on a site survey or from pictures and details for simple jobs. A fixed-price quote follows.

What a service looks like in Park Street
About 40% of homes in Park Street and the neighbourhoods around it date from 1945 to 1972, according to Valuation Office Agency council tax records, and about 62% of households live in detached or semi-detached houses, according to the last census (2021). Wall bracket, ground pad or flat roof: knowing where the outdoor unit is saves time on the day. The centre of Park Street lies within 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. Swapping an outdoor unit on a listed building or in a conservation area may need consent, so we’ll flag it if a replacement is needed.
If you look after a school such as Park Street Church of England Voluntary Aided Primary School, servicing is easiest in the holidays.

What affects the quote in Park Street
The quote reflects the job in front of us. We take into account:
- Whether it’s a one-off job or part of a maintenance contract
- How far the pipework has to run, and where
- The brand, model and parts involved
A single unit or a whole estate, the quote is built the same way: the work involved, the access and the equipment. The price is fixed before we start, with VAT shown clearly.
Before you get in touch
Simple jobs can often be priced from photos and some basics. Send what you can of the following:
- The address and the type of property
- A few photos of the room and the wall the unit is on, or will go on
- The rating plate or label on any existing unit
VAT is set out clearly on every quote, and the rate that applies to your job is stated. Homes, businesses and different kinds of work can be treated differently for VAT, so we confirm it in writing rather than guess. To get one, phone us on 07833 053749 or write to us at info@aircondoctor.co.uk.
When to call us in Park Street
When the system cools, water condenses on the indoor coil. Dust sticks to a wet surface, and over time the coil and drain tray can get dirty enough to smell.
Customers normally contact us after spotting one of these:
- Condensate leaking into the room
- Noisy fans or rattling from the outdoor unit
- Systems that need a 6 or 12-monthly leak check
If you run premises near Park Street station, ask about servicing several units in one visit.
What to look for in a quote
- Whether the price is fixed or an estimate
- Whether you get F-Gas records where refrigerant is involved
- Whether the manufacturer’s warranty depends on regular servicing
