Air con repairs in Teddington
Our engineers work in Teddington on fault finding and repair for split, multi-split, ducted, cassette and VRF air conditioning, whatever the brand. Diagnosis first, a fixed price and proper paperwork when we finish.
- Ice forming on the indoor unit or pipes
- A fault code on the display
- Water dripping from the indoor unit
What we do, step by step
Where something has to be switched off during the work, we agree it with you first so it doesn’t catch you out. In a business, work can often be done one area at a time. The work takes a single visit for many faults, while some repairs need a second visit once parts arrive. Managed buildings in London often need contractors booked in, and we can deal with the agent for a job in Teddington.
- You tell us the symptoms, the make and any error 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.
- The system is run and checked, and you get a written note of the repair.
Preparing for the visit
- Clear a path to the units and the space around them
- Make sure we can reach the outdoor unit, or where it will go
- Arrange for someone to be there to let us in

Advice
Air conditioning repair in Teddington, done properly
Diagnosis call-outs start from £75 + VAT. When the cause is found, the repair is priced before anything else is done, so you can decide with the facts in front of you. The work covers multi-split systems, VRF systems and ceiling cassettes, and common reasons people get in touch are a suspected refrigerant leak and air conditioning running but not cooling.
In a London area like Teddington, a lot of the systems we repair serve flats and small offices, where the outdoor unit may be on a balcony, a rear wall or the roof. Knowing where the outdoor unit sits, and how to get to it, helps us plan the repair.
Refrigerant work is written up in the F-Gas records: what was done, the refrigerant type and any amount added or recovered. Keep the records with the manual and the warranty documents, ready for the next service or a warranty query.

What the work involves, system by system
Refrigerant leaks
Adding refrigerant without a repair isn’t a fix and the gas simply leaks out again. That is why we repair the leak first.
Ducted and cassette systems
Water through a ceiling below a cassette or ducted unit needs prompt attention. A failed pump, a blocked drain or an overflowing tray is normally behind it and the diagnosis covers each of them.
Questions from Teddington
Do you cover Teddington for air conditioning repair?
Yes. Teddington is one of the places we cover. To start, give us a ring on 07833 053749 or email us with a few pictures.
Can I get a fixed-price quote for air conditioning repair in Teddington?
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.
What accreditations do you have?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, and we’re Checkatrade members. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
Whose job is it to check the system for leaks?
Whoever operates the equipment, together with the technicians who service it. 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 will work out which band applies to yours.
Can landlords and managing agents book you?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size in Teddington and across Greater London. Let us know who the records should go to.
My air con is showing an error code. What should I do?
An error code points us in the right direction, but testing confirms the cause. Write down the code and turn the unit off if it has stopped, then give us a ring on 07833 053749 or email us.
Can I fit air conditioning or a heat pump myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That is the law, not just our preference, and manufacturers expect it for their warranty too. We’re happy to quote for the full job, supply to commissioning.

What air conditioning repair cannot fix
To be straight with you, some problems need a different answer:
- Cooling that falls short because the system is too small
- A refrigerant fault on an R22 system (new R22 cannot be used for servicing, so replacement is typically the answer)
- Heat gains the system was never designed for
If you are not sure, just give us a ring on 07833 053749 or email us and we will give you a straight answer.
Where we work
- Wall-mounted split systems
- Heat pumps
- Ceiling cassettes
- VRF systems
- Multi-split systems
- Ducted systems
Keeping the system healthy
Looking after the system is mostly common sense. A few tips:
- Switch the unit off if water is leaking from it
- Write down the fault code if there is one
- Only let an F-Gas qualified engineer work on the refrigerant
If the same symptom comes back, tell us straight away. Let us know what the system is doing and any code on the display and we’ll come back to it.
Give the outdoor unit space. Leaves, plants and stored items around it restrict airflow and make the system work harder and debris drawn into the fan can cause noise and damage.
