- Pipework or drainage that was badly installed in the first place
- A unit that was undersized when it was chosen

How we handle air conditioning servicing in Northfleet
Whether a leak check is required depends on how much refrigerant the system holds and which refrigerant it is. Under the GOV.UK rules, 5 to under 50 tCO2e means a leak check at least every 12 months, and 50 to under 500 tCO2e means every 6 months. We work out where your system sits and check it accordingly. The work covers ducted systems, VRF systems and ceiling cassettes, and people most often call us about error codes or flashing lights on the indoor unit and systems that need a 6 or 12-monthly leak check.
A service in Northfleet normally starts with the filters and the indoor coil, then the drain, the outdoor unit and the electrics, before testing the system and checking for refrigerant leaks.
Refrigerant work is written up in the F-Gas records: the work carried out, the refrigerant involved and the quantities. File them with the system’s paperwork, ready for the next service or a warranty query.

Owner checks or an engineer?
Owner care supports servicing; it does not replace it. Clean filters and a clear outdoor unit help the system run as it should, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
Some faults have simple causes you can check first: check the mode, the set temperature, the remote’s batteries and the breaker. If the breaker trips a second time, leave it off and call 07833 053749 or use the quote form.
Why act early in Northfleet
Some manufacturers may set conditions on their warranties, and servicing may be among them. If servicing is one of the terms, a missing service record could matter if you ever need to make a claim. We can go through the terms with you. A dirty or faulty system works harder and costs more to run.
No two properties are the same, so each one gets its own fixed-price quote. The system, the access, the pipe routes and the parts involved all play a part.

Can you do air conditioning servicing in Northfleet?
Yes. We work across London and the South East from our base in East Grinstead, and Northfleet is part of that. To start, phone us on 07833 053749, or email if that’s easier with a few photos.
How often do you service systems in Northfleet?
Typically once a year for homes, more often for busy business systems. Check your manufacturer’s warranty terms too, as some of them make regular servicing a condition.

Yes. We look at it first and tell you what we find, including any issues with how it was fitted. You get a fixed price before any work goes ahead.

The process
Each visit runs to the same pattern: agree the plan on site, protect the area, 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. Access to the outdoor unit position is the main thing to tell us about in Northfleet.
- A date is fixed and the service price confirmed in advance.
- The engineer runs the system and checks how it’s performing.
- Then the cleaning: filters, coils, fan and the drain line.
- Electrical and refrigerant checks follow, including a leak check if the rules require one.
- It’s run once more to confirm all is well, and the record is left with you.
Preparing for the visit
- Let us know where the consumer unit is
- Mention any managing agent or landlord rules we need to follow
- Clear a path to the units and the space around them

Advice
Air conditioning servicing around Northfleet
The coast is only about 3 miles from Northfleet. Coastal outdoor units are worth checking for corrosion at every service. About 37% of households live in terraced houses, according to the 2021 Census. With a terrace, access to the rear for the outdoor unit is the main thing to tell us. In the mile around Northfleet’s centre, 5 conservation areas have been designated. Listed buildings are part of the picture here: about 9 within half a mile of the centre, such as Church of All Saints (grade II*). Day-to-day work on an existing system isn’t affected; a replacement outdoor unit on a protected building might be.
If you can’t remember the last service, it’s probably due. For a school like Northfleet Technology College, maintenance visits can be booked out of term.
