What happens on the day
Refrigerant work is done by qualified engineers working for an F-Gas certified company, while the electrical side is covered by our NICEIC approval. So on the day, you do not need a separate electrician for the electrical side. On site, it takes anything from an hour or so to a full day, depending on the fault and the parts. Photos of the existing unit help with repairs and servicing in Nalderswood.
- We start with what the unit is doing, the make and any code.
- On the diagnosis visit, we test the electrics, airflow, drain and refrigerant.
- You get the cause explained and a fixed price for the repair.
- With your go-ahead, we carry out the repair, recording any refrigerant work.
- It’s tested running, and the write-up is left with you.
Preparing for the visit
- Plan for pets to be kept clear during the visit
- Make sure we can reach the outdoor unit, or where it will go
- Mention any roof access, ladders or high-level work

Advice
About our air conditioning repair in Nalderswood
We treat a faulty system the way a doctor treats a patient: find the cause, put it right and check it’s healthy before we leave. Guessing is expensive, and replacing a board when the fault is a sensor leaves the problem in place. The work covers heat pumps, wall-mounted split systems and ceiling cassettes, and common reasons people get in touch are frost on the pipework and a system that won’t switch on.
We plan the trip to Nalderswood so the repair can be finished in one visit where possible, unless a part has to come from the manufacturer.
AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

When to call us in Nalderswood
When the fan runs but the air isn’t cold, there are some common causes: 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. Diagnosis narrows it down.
If any of these sounds familiar, it’s worth a diagnosis:
- Drips from the indoor unit
- Rattling, buzzing or grinding noises
- A unit that barely blows any air
A photo of the error code and the unit’s rating label helps us plan the repair.

Nalderswood questions
Do you cover smaller places like Nalderswood?
Yes, and the size of the place makes no difference to how we work. Send a few details and pictures, and we reply the same working day.
Do you cover Nalderswood for air conditioning repair?
Yes. We work across London and the South East from our base in East Grinstead, and Nalderswood is part of that. Tell us a little about the job and we’ll take it from there.
Which accreditations do you hold?
We are an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We’re members of Checkatrade too.
Will you make a mess?
We start with protection: sheets over the floor and nearby furniture. Holes and fixings are agreed with you, and we clean up afterwards when we finish.
How soon will you get back to me?
The same working day. After that, we agree a survey, diagnosis or installation date that suits you, and you get a fixed price before any work goes ahead.
My system uses R22. Can it be repaired?
R22 is an ozone-depleting refrigerant, and new R22 can’t be used for servicing. Some non-refrigerant faults can be repaired if parts are available, but a leak usually makes replacement the sensible route. We will set out the options and quote for a replacement where it makes sense.
Why use an F-Gas certified company?
Companies working on equipment that contains F gas must be certified by an approved body, and each engineer needs the right qualifications too. It’s how you know the refrigerant is being handled legally and safely.
Looking after your system
Think of this as the after-treatment advice, short and simple:
- Rule out the simple causes first: filter, mode and temperature
- Leave a tripping breaker off and call us
- Stop the unit if water is coming through a ceiling
Where a repair needs parts, we explain what’s been ordered and agree the return visit with you. We don’t promise dates we can’t control and we’ll keep you updated.
Clean the filters regularly. Blocked filters cut airflow, which can lead to poor cooling, ice on the coil and drips and the manual shows how to clean them.
What air conditioning repair can’t fix
We’d rather tell you now than sell you work that will not help, so here are the limits:
- A building problem rather than a system fault
- An old system with obsolete parts
- A refrigerant fault on an R22 system (new R22 cannot be used for servicing, so replacement is usually the answer)
If in doubt, ring 07833 053749 or email us and we will say what we think before you book.

- Multi-split systems

Census 2021 figures found about 72% of households in detached or semi-detached houses. Let us know where the outdoor unit sits and whether a ladder is needed to reach it.

Day-to-day work on an existing system is not affected; a replacement outdoor unit on a protected building might be.
