What happens on the day
Every visit follows the same order: agree the plan on site, put the dust sheets down, carry out the job, check the system and talk you through it. The visit itself takes a short visit for one split system, longer for multi-split, ducted or commercial plant. Seeing the property in pictures first helps us plan the trip to Harefield.
- First we take the details: brand, model if you have it, how many indoor units and anything that’s been bothering you.
- We run the system first and see how it’s performing.
- Filters are cleaned, coils treated and the drain tray and pipe cleared.
- Temperatures and pressures tell us how the refrigerant circuit is doing, alongside checks on the wiring and controls.
- We leave you a record of the service and explain anything we found.
Before we arrive
- Mention any roof access, ladders or high-level work
- Move furniture away from the wall where we’ll be working
- Clear access to the fuse board

About our air conditioning servicing in Harefield
A service is not the same as a regas. The refrigerant circuit is sealed, so a system that is short of gas has a leak somewhere. Where the checks suggest gas has been lost, the right step is to find the leak, and we’ll set out how. Common call-outs are for ice forming on the pipework or outdoor unit and a system that struggles to cool on warm days, across ducted systems, VRF systems and wall-mounted split systems.
In a place like Harefield, the outdoor unit often sits near a garden, hedge or trees, so the outdoor coil can clog with leaves and seeds. Cleaning it is part of every service.
The records are your 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.

Why deal with it now?
Smells from an indoor unit tend to come back each time it runs. Cleaning the coil, the fan and the drain tray deals with the cause instead of covering it up. For a place like Harefield, booking ahead lets us plan the visit properly.
Leaving a fault or an overdue service rarely makes the work cheaper. Small problems, from blocked filters to slow leaks, tend to get worse, and a struggling system uses more electricity to do less. If you’re unsure, ring us on 07833 053749 or fill in the contact form and we’ll give you an honest view and a fixed price.

Questions from Harefield
Do you cover Harefield for air conditioning servicing?
We do: Harefield falls inside our working area. Get in touch with the details and we reply the same working day.
Does my air con in Harefield need a yearly service?
For most homes, once a year. Some manufacturers’ warranty terms ask for regular servicing, so it’s worth keeping the records.
Do you survey before quoting?
Yes, always. Diagnosis comes before treatment: the survey tells us what the job needs and how to do it and the fixed price is built on it.
Will servicing keep my manufacturer’s warranty valid?
The answer is in your manufacturer’s warranty conditions. Where servicing is a condition, keeping an annual service record helps show the terms were followed and we’ll help you check what applies.
Does my air conditioning need an F-gas leak check?
The requirement starts at 5 tCO2e. Many small split systems fall below it: 3 kg of R32, for instance, is about 2.0 tCO2e. We check the label and tell you whether your system needs checks and how often.
Why does F-Gas certification matter?
The law says any company working on equipment containing F gas has to be certified, and each engineer needs the right qualifications too. It’s how you know the refrigerant is being handled legally and safely.
What’s included in an air conditioning service?
Filters, coils, fans and the condensate drain are all cleaned and checked. We also check the electrical connections, the controls and the refrigerant performance plus a leak check on systems that need one.
When to call us in Harefield
A slow leak can go unnoticed for a long time. Performance drops slowly, until it can’t keep up on the hottest or coldest days.
These are the situations we see most often:
- A unit showing a fault code
- Water dripping from the indoor unit
- Air conditioning that is not cooling as well as it did
Site managers at schools like Harefield Infant School can have the site’s units serviced during a holiday.

Honest limits
Not every problem is solved by air conditioning servicing, and we’d rather say so up front. It doesn’t solve:
- A failed compressor, fan motor or circuit board, which needs a repair
- Heat gains the system was never sized for
- Pipework or drainage that was badly installed in the first place
If in doubt, phone us on 07833 053749 or send an email and we’ll say what we think.

Keeping systems in Harefield running
Central Harefield is inside the Harefield Village Conservation Area. There are 2 conservation areas within a mile of the centre of Harefield. Listed buildings are part of the picture here: about 15 within half a mile of the centre, such as Harefield House (grade II). That only matters for replacements, where a new outdoor unit on a protected building can need consent. About 42% of homes in the Harefield area date from 1945 to 1972, according to the Valuation Office Agency’s council tax figures. 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.
