Air conditioning repair in Twickenham, done properly
A diagnosis call-out is from £75 + VAT. When the cause is found, the repair is priced before anything else is done and nothing goes ahead without your say-so. The work covers ceiling cassettes, multi-split systems and VRF systems, and common reasons people get in touch are water dripping from the indoor unit and a suspected refrigerant leak.
In a London area like Twickenham, 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.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. Where yours does, a regular service with us keeps that side in order, and every service is written up.

Why deal with it now?
Refrigerant supply is changing. Repairing and recharging existing R410A systems is still legal, but R410A is getting scarcer and dearer to buy as the GB phase-down tightens and we weigh that up when we advise you. Planning ahead in Twickenham means you choose the date, not the weather.
Height, access and the distance between the indoor and outdoor units can all change the price. We take each of them into account, and the price is fixed before any work starts.

Looking after it afterwards
Aftercare is straightforward, and it makes the next visit easier:
- Leave a tripping breaker off and call us
- Only let an F-Gas qualified engineer work on the refrigerant
- Let any ice thaw before the engineer arrives
A returning symptom is worth reporting quickly. Let us know what the system is doing and any code on the display and we’ll come back to it.
Sensible use helps. Choose the right mode and a moderate set temperature, and keep doors and windows closed while it runs and the system does not have to work as hard.
How the visit works
Where something has to be switched off during the work, we agree it with you first so it does not catch you out. For businesses, we can normally work room by room or zone by zone. The work takes a single visit for many faults, while some repairs need a second visit once parts arrive. Parking bays, permits and roof or balcony access are the first things we ask about in Twickenham.
- 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.
- 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
- Name a contact who can meet us at the agreed time
- Keep pets out of the rooms we’re working in
- Clear access to the fuse board

Twickenham questions
Can you do air conditioning repair in Twickenham?
We do: Twickenham falls inside our working area. Get in touch with the details and we reply the same working day.
Who do I call if my air conditioning fails in Twickenham out of hours?
The emergency line is open around the clock, and Twickenham is one of the places it covers. Say what the system is doing and whether it shows a code, and we will advise on the next step.
Which accreditations do you hold?
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.
What does F-Gas certified mean?
The law says any company working on equipment containing F gas has to be certified, and each engineer needs the right qualifications too. It means the refrigerant in your system is handled legally.
Do you look at the job first?
Yes. For simple jobs, pictures and a few details can be enough, while larger systems and faults that need testing are seen on site.
What causes water to leak from an air conditioning unit?
Typically a blocked or kinked condensate drain, a failed condensate pump or a unit that is not level. Ice on the coil from low airflow or low refrigerant can also melt and drip. Switch the unit off and call 07833 053749 or email us.
Which manufacturers do you install and repair?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For a new system, we suggest the make and model that suit the property and tell you why.

Air conditioning repair in Twickenham: the local picture
Twickenham’s centre is no more than about a third of a mile from the Hamilton Road Conservation Area. 14 conservation areas lie within a mile of central Twickenham. Listed buildings are part of the picture here: about 22 within half a mile of the centre, such as Church of All Hallows (grade I). Day-to-day work on an existing system is not affected; a replacement outdoor unit on a protected building might be. Valuation Office Agency council tax records put about 39% of homes in Twickenham and the neighbourhoods around it before 1919. If the outdoor unit is high up or behind a locked gate, mention it when you book. 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 St Richard Reynolds Catholic Primary School, we can time non-urgent repair work around lessons.

What a customer said
“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.”
