Air conditioning servicing in Colney Street
Servicing covers both halves of the system: the indoor units in the rooms and the outdoor unit outside. Filters and coils are cleaned, the drain is cleared, and the electrics, controls and refrigerant performance are all checked. We service systems in Colney Street and across Hertfordshire, whatever the make. If you are dealing with condensate leaking into the room and systems that haven’t been serviced for a while, we can sort it out.
We plan the trip to Colney Street and can service more than one unit in one visit.
Think of the paperwork as the system’s health record: what was fitted or found, what was done and when. It makes the next visit quicker and any warranty question simpler, so keep it safe.

Landlords, agents and facilities managers
Landlords, letting agents and managing agents book us, not only the people who live or work in the property. Let us know who will give us access and who the records should go to, and we’ll keep everyone informed.
Running several properties is easier with one contractor. Our area covers Greater London and the South East, so a run of properties can go into one programme and kept on a regular cycle.
What we do, step by step
The first job on site is protection: sheets over the floor and any furniture nearby, and we ask before moving anything. Then the electrics are made safe and the work begins. The work on site takes an hour or two for most homes, and longer where there are several indoor units or a ducted system, and we tidy up before we leave. For a village like Colney Street, tell us about narrow lanes, gates and parking when you book.
- We start with the basics, such as the brand, the number of indoor units and any symptoms.
- On arrival, a quick performance check shows how well it’s working before the clean.
- Filters are cleaned, coils treated and the drain tray and pipe cleared.
- Electrical connections, controls and refrigerant performance are checked, with an F-gas leak check where the system requires one.
- A service record follows, with any faults and the options for fixing them.
Preparing for the visit
- Have the make and model of any existing unit to hand
- Tell us about parking and loading
- Clear the space around the indoor unit, or where it will go
Getting a quote
Some jobs can be priced from pictures, while others need a survey. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, the quote is fixed before anything goes ahead.

What you can do yourself, and what needs us
Never try to top up, release or handle refrigerant yourself. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and refrigerant lines can cause cold burns. A suspected leak is our job, not yours.
There are a few things you can safely do yourself: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Anything inside the units, the electrics and the refrigerant is engineer’s work.
Why it’s worth doing now in Colney Street
A service can find a worn part or a loose connection while the system is still running. Waiting until the unit stops means dealing with it on the hottest day of the year. Planning ahead for a job in Colney Street means we can bring everything needed.
Putting several jobs into one visit can make for a more efficient booking. Tell us about everything you’d like looked at, and you’ll get one fixed price.

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 work on systems someone else installed?
Yes. We start with a proper look and tell you honestly what we find, including anything about the original installation that needs putting right. You get a fixed price before any work goes ahead.
What do you check on an air conditioning service?
We clean the filters and coils, clear the condensate drain and check the fans. The electrics, controls and refrigerant circuit are tested too, with an F-gas leak check where the system requires one.
Do you work on all makes?
We work with the leading brands, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
Can you set up regular servicing?
Yes. Send details of the systems and how they’re used and we’ll propose a schedule and quote for it. Leak checks required by the F-gas rules can be built in for larger systems.

Servicing in Colney Street: local notes
Listed buildings are part of the picture here: about 6 within half a mile of the centre, such as The George and Dragon Public House (grade II). We keep it in mind in case a new outdoor unit is ever needed, as protected buildings can need consent for that. The Valuation Office Agency’s council tax figures date about 40% of homes in the Colney Street area to the post-war years, 1945 to 1972, and about 62% of households live in detached or semi-detached houses, according to the last census (2021). A photo of the outdoor unit and its surroundings tells us what access the visit needs.
Spring is a good time for a service, before the system is needed for cooling. Schools such as Park Street Church of England Voluntary Aided Primary School can book servicing for half term or the summer break, when rooms are empty.
