Air Conditioning Repair in Lewknor
Air conditioning repair in and around Lewknor, from the first look to the final check and a fixed price agreed before any work starts.
- Poor airflow even with clean filters
- A system that will not switch on
- Ice on the pipework or the coil
Aftercare tips
How well a system lasts depends on use and care. We suggest:
- Keep the outdoor unit clear of leaves and clutter
- Stop the unit if water is coming through a ceiling
- Only let an F-Gas qualified engineer work on the refrigerant
You get a note of the fault and what we did: what was wrong, what was replaced and any refrigerant work. Any refrigerant work is recorded in the F-Gas records and it belongs with the system’s paperwork.
Small changes are worth acting on. A drip, a new noise, a weaker airflow or an occasional error code is often the first sign of a fault, and early diagnosis typically means a smaller repair.
How we handle air conditioning repair in Lewknor
A sealed system shouldn’t lose refrigerant, so a low charge means a leak somewhere. Simply adding gas means it will leak away again. We find and fix the leak, pressure test, evacuate and recharge to the manufacturer’s charge, then record it in the F-Gas records. The work covers VRF systems, ducted systems and multi-split systems, and common reasons people get in touch are a unit that barely blows any air and water dripping from the indoor unit.
A visit to Lewknor is planned so we can usually finish in one go, unless a part has to come from the manufacturer.
Whatever the visit, you get a written record: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. File it with the manual, because it helps with any later warranty question.

Lewknor questions
Do you cover Lewknor for emergency air conditioning repairs?
Yes. Our 24/7 emergency line covers Lewknor. Say what the system is doing and whether it shows a code, and we will advise on the next step.
Do you cover smaller places like Lewknor?
Yes. Lewknor is within the area we cover across London and the South East. Visits to smaller places are planned so the engineer arrives with what the job needs.
Can we book visits on a schedule?
Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Each visit is written up and F-Gas records kept where they apply.
What causes water to leak from an air conditioning unit?
Most leaks come from a blocked drain, a failed pump or a unit that has dropped out of level. Ice on the coil from low airflow or low refrigerant can also melt and drip. Turn it off and phone 07833 053749 or drop us a line.
What can I do with an old R22 system?
Replacement is normally the better answer. New R22 can’t be used to service systems, and parts for older units are getting harder to find, so a new system on a modern refrigerant is usually the better investment.
Do I get paperwork after the visit?
Yes. It’s your proof of what was done: a dated note of the work, with refrigerant details where they apply.
Who has to arrange F-Gas leak checks?
Responsibility is shared between the operator, normally whoever owns or controls the equipment, and the service technicians. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Owner checks or an engineer?
Keep a note of anything odd: error codes, noises, drips, smells or a drop in performance. It makes our diagnosis quicker, and a photo of the display helps even more.
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do where the manufacturer’s manual explains how. They come out, get a gentle clean and go back only when they’re dry. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
What happens if it’s left?
For a newer system, a fault may be covered on the manufacturer’s terms. Send us the make, model and installation date, and we’ll explain how the manufacturer’s warranty is likely to apply before any chargeable work. Getting the date in early helps for a place like Lewknor.
The pipe route, the height of the units and how we reach them all affect the cost. Each of those is built into the quote, and the price is fixed before work begins.
