Air conditioning repair in North Waltham, done properly
When air conditioning stops cooling, leaks water or shows an error code, the symptom rarely tells you the cause. A unit blowing warm air might have a blocked filter, a failed sensor, a fault on the circuit board or a refrigerant leak, so we diagnose before we repair. The work covers VRF systems, wall-mounted split systems and ceiling cassettes, and the jobs we see most are drips from the indoor unit and a suspected refrigerant leak.
Outdoor units in a place like North Waltham can be near hedges and fields, so leaves, seeds and cobwebs on the coil are worth checking first.
Equipment warranty comes from the manufacturer, on its own terms, and we explain those terms on your quote. Terms differ from brand to brand, and we’re happy to talk you through them.

What we’re called out for in North Waltham
A unit that runs but doesn’t cool has a few usual suspects: a blocked filter, the wrong mode or set temperature, an outdoor unit that cannot breathe, a failed sensor or board, or low refrigerant from a leak. Testing tells us which.
Any of these is worth a proper look:
- An error code or flashing light on the unit
- New noises from the system
- A system that needs topping up again
The make, model and error code are the most useful things to tell us.
Before booking anyone
- Whether a new circuit is included and who certifies it
- How VAT is shown, and which rate applies
- Whether the price is fixed or an estimate
What happens on the day
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. At the end, we tidy up and run through the work with you. Photos of the existing unit help with repairs and servicing in North Waltham.
- It starts with the symptoms: what the unit is doing, the make and any code on the display.
- We diagnose on site, checking the codes, electrics, airflow, drain and refrigerant pressures.
- Nothing is repaired until you’ve heard what’s wrong and agreed a fixed price.
- With your agreement the part is replaced or the fault put right, and refrigerant work goes in the F-Gas log.
- Before leaving, we run it through its modes and write up what was found and done.
How to prepare
- Dig out any previous service or F-Gas records
- Arrange for someone to be there to let us in
- Tell us about access, such as roof hatches, high walls or locked plant areas

Photos are the fastest route to a quote: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Add the address and what you’d like done, and simple jobs can often be priced without a visit.

Your questions about air conditioning repair in North Waltham
Do you cover smaller places like North Waltham?
Yes, and the size of the place makes no difference to how we work. Visits to smaller places are planned so the engineer arrives with what the job needs.
Can you do air conditioning repair in North Waltham?
Yes, North Waltham is within the area we cover. Just ring 07833 053749 or send an email with a few details.
Which brands do you work with?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For a new system, we suggest the make and model that suit the property and tell you why.
What causes ice on the indoor coil?
When airflow drops or refrigerant is lost, the coil gets cold enough to ice. A dirty filter is worth checking first, and if it’s clean, the system needs a diagnosis.
My air con is showing an error code. What should I do?
The code is the system’s own clue to the fault, but it is not the whole answer. Note the code and switch the system off if it is not working, then ring 07833 053749 or fill in the contact form.
Will I get records for the system?
Yes, always. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, while repairs and services get a written note of what was found and done.
Do you work for landlords and businesses?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size across London and the South East. Tell us who should receive the paperwork.
Safe owner checks
On air conditioning, the filters in the indoor unit are normally the one part owners can clean where the manufacturer’s manual explains how. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
Refrigerant is off limits for anyone without the right qualifications. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and refrigerant lines can cause cold burns. If you suspect a leak, switch the system off and call us.
