Air conditioning repair for homes and businesses in Northmoor
A symptom is only a clue: warm air, drips and error codes can each have several causes. 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, ducted systems and heat pumps, and people most often call us about an error code or flashing light on the unit and a unit that has lost refrigerant.
We plan the trip to Northmoor 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.

What happens if it’s left?
Leaving a fault seldom makes it go away. A blocked drain becomes water damage, and a slow leak drains the refrigerant until the compressor is working far harder than it should, so getting it looked at early typically means a simpler repair. Getting the date in early helps for a place like Northmoor.
Leaving a fault or an overdue service rarely makes the work cheaper. Faults and wear in a system tend to grow, and a struggling system uses more electricity to do less. If you’re unsure, phone us on 07833 053749 or use the quote form for straight advice and a fixed price.

What a repair looks like in Northmoor
The centre of Northmoor lies within the Northmoor Conservation Area. Listed buildings are part of the picture here: about 17 within half a mile of the centre, such as Church of St Denys (grade I). Day-to-day work on an existing system is not affected; a replacement outdoor unit on a protected building might be. About 37% of homes in the Northmoor area have been built since 2000, according to VOA council tax data, and Census 2021 figures found about 86% 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.
A photo of the error code and the unit’s rating label helps us plan the repair. Weak cooling, water dripping from the indoor unit and error codes are the faults we are called about most.

Safe owner checks
Before you call us about a fault, a few checks can save a visit: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If the breaker trips a second time, leave it off and phone us on 07833 053749 or fill in the contact form.
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do, if the manual says so. 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 on the day
Each visit runs to the same pattern: agree the plan on site, protect the area, carry out the job, test what we’ve done and talk you through it. The visit itself takes as long as the fault needs, from a quick fix to a return visit for parts. Work in Northmoor is booked in advance at a time that suits you.
- First the diagnosis: fault codes read, electrics and airflow checked, drain and refrigerant tested.
- Prescribe: tell you the cause and the fixed cost of the cure.
- Where a repair doesn’t make sense, you will hear it from us, with the alternatives.
- Treat: carry out the repair, sealing any leak before refrigerant goes back in.
- The sign-off: the system tested in operation and the work recorded.
How to prepare
- Let us know if the units are on a roof, a high wall or in a locked area
- Let us know where we can park and unload
- Move furniture away from the wall where we will be working

Northmoor questions
Who do I call if my air conditioning fails in Northmoor out of hours?
The emergency line is open around the clock, and Northmoor is one of the places it covers. A diagnosis call-out starts from £75 + VAT, and knowing the brand and the symptoms helps us plan it.
Do you cover Northmoor for air conditioning repair?
Yes. We work across London and the South East from our base in East Grinstead, and Northmoor is part of that. To start, ring us on 07833 053749 or drop us a line with a few photos.
How much is an air conditioning call-out?
It starts with a diagnosis call-out from £75 + VAT, followed by a fixed price for the repair. Nothing goes ahead without your agreement.
Will you make a mess?
We start with protection: dust sheets over floors and anything close to the work. Holes and fixings are agreed with you, and we clean up afterwards before we leave.
Whose job is it to check the system for leaks?
The operator of the equipment, working with qualified engineers. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We’ll work out which band applies to yours.
What warranty do I get?
The manufacturer provides it, on its own terms. Some terms depend on regular servicing by a qualified engineer so it’s worth keeping the service records.
Will I get records for the system?
Yes. It’s your proof of what was done: the date, the work, and any refrigerant added or recovered.
From one of our customers
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
