Air conditioning repair in Forest Hill
Think of it as a doctor’s appointment for your air conditioning: diagnose the cause, treat it properly and sign it off when it’s working. Guesswork costs money, and replacing a board when the fault is a sensor leaves the problem in place. If the problem is water dripping from the indoor unit and a system that runs but doesn’t cool the room, we can help.
Many buildings in Forest Hill have a managing agent or security desk, so let us know who needs to know we are coming. Roof access can need keys or permits, and we plan for that before we arrive.
Nothing is signed off by word of mouth: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. File it with the manual so it’s to hand next time.

Looking after it afterwards
Simple habits make a real difference. Our advice:
- Ask for the leak to be found, not just a top-up
- Check the settings and the remote’s batteries first
- Leave space around the outdoor unit
Where a repair needs parts, we explain what’s been ordered and agree the return visit with you. Parts lead times depend on the supplier, so we keep you posted.
Clean the filters regularly. Clogged filters starve the unit of air, and that can cause ice, drips and poor performance and the manual shows how to clean them.

When air con fails in Forest Hill
The Forest Hill Conservation Area lies close to the centre of Forest Hill, within about a third of a mile. In the mile around Forest Hill’s centre, 7 conservation areas have been designated. Fairlawn School, listed at grade II, is one of roughly 26 protected buildings and structures in the half-mile around Forest Hill’s centre. Should a unit ever need replacing on a listed building or in a conservation area, ask us about consent first. The Valuation Office Agency’s council tax figures put about 57% of homes across Forest Hill and its surrounding area before 1919, and about 58% of households live in flats, according to the last census (2021). If you live in a flat, mention any roof hatch, balcony or managing agent we will need to get to the outdoor unit. In London buildings, outdoor units can be on roofs or in light wells, so let us know where yours is.
When cooling fails at a school like Fairlawn Primary School, we can time non-urgent repair work around lessons.

Common problems we fix in Forest Hill
Error codes are the system telling you it has found a fault. Codes differ by brand, and one code can cover several faults, so we read the code and then test to confirm. Sensors, communication faults between the units and circuit boards are frequent culprits.
Reasons to give us a call include:
- Air conditioning running but not cooling
- Drips from the indoor unit
- Poor airflow even with clean filters
Near Honor Oak Park station, as anywhere, a photo of the error code on the controller is the quickest way to start a repair.

FAQs for Forest Hill
Can I get a fixed-price quote for air conditioning repair in Forest Hill?
Send us photos of the room or the system and a few details about the property. We reply the same working day, and the quote is fixed before any work starts.
Can you do air conditioning repair in Forest Hill?
Yes, Forest Hill is within the area we cover. Get in touch with the details and we reply the same working day.
What can I do with an old R22 system?
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 refrigerant leak normally means replacement. We’ll set out the options and quote for a replacement where it makes sense.
Will you work on another installer’s system?
Yes. We start with a proper look and tell you honestly what we find, including anything about the original installation that needs putting right. You get a fixed price before any work goes ahead.
What causes ice on the indoor coil?
Ice is a symptom of low airflow or low refrigerant. Blocked filters, a failing fan or a leak are the common causes. Turn it off, let the ice melt and ring us on 07833 053749 or email us.
What accreditations do you have?
AirCon Doctor is an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We’re also Checkatrade members.
Why is my air conditioning showing a fault code?
The code is the system’s own clue to the fault, but it is not the whole answer. Write down the code and turn the unit off if it has stopped, and call us on 07833 053749 or use the quote form.
The process
Our engineers arrive at the time agreed with you and check the plan with you first. Dust sheets go down over floors and anything close to the work, and the electrics are made safe before any panel comes off. On site, it takes as long as the fault needs, from a quick fix to a return visit for parts. Photos of the room and where the outdoor unit could go let us plan most of a visit to Forest Hill in advance.
- We start with what the unit is doing, the make and any code.
- The engineer diagnoses the fault on site, testing rather than guessing.
- The fault is explained simply and the repair priced up front.
- Once agreed, the repair goes ahead.
- We test the system in operation and leave you a note of the fault and the fix.
Preparing for the visit
- Clear the space around the indoor unit, or where it will go
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Mention any parking restrictions near the property
Getting a quote
Quoting starts with a diagnosis, either on a site survey or, for simple jobs, from your pictures and details. After that, we send a fixed price so you know the cost before we begin.
Related advice
Owner checks or an engineer?
Refrigerant is off limits for anyone without the right qualifications. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and escaping refrigerant can cause cold burns. A suspected leak is our job, not yours.
There are a few things you can safely do yourself: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Anything inside the units, the electrics and the refrigerant is engineer’s work.
