How we handle air conditioning repair in Millbank
Faults on all the leading makes are part of our everyday work, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. It does not matter who installed it and the make and model help us prepare. We’re often asked to deal with air conditioning running but not cooling and a unit that won’t start, on wall-mounted split systems, ducted systems and heat pumps.
London systems in Millbank often run long hours in summer, which is when weak cooling, leaks and error codes tend to appear. The error code on the display, the make and the model are the most useful things to send us.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we explain those terms on your quote. Terms differ from brand to brand, so we go through them with you rather than leave you to find the small print.

Your questions about air conditioning repair in Millbank
What’s the best way to get a price for air conditioning repair in Millbank?
Start with a short message: the address, what you need and a picture or two. We reply the same working day, and the quote is fixed before any work starts.
Who do I call if my air conditioning fails in Millbank out of hours?
Yes. Our 24/7 emergency line covers Millbank. Say what the system is doing and whether it shows a code, and we will advise on the next step.
Who has to arrange F-Gas leak checks?
The operator of the equipment, working with qualified engineers. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We will work out which band applies to yours.
What causes ice on the indoor coil?
The coil gets too cold when air can’t move across it or when the refrigerant charge is low. Check the filter first, and if it’s clean, the system needs a diagnosis.
Can you look at a system you didn’t fit?
Yes. Systems fitted by other companies are fine, on all the main brands. Tell us the make and model and send any paperwork you have.
Does servicing affect my warranty?
Check the manufacturer’s terms. Some warranty terms require the system to be serviced regularly by a qualified engineer, so check the terms or ask us. Keep every service record either way.
Can I fit air conditioning or a heat pump myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That is the law, not just our preference, and it also matters for the manufacturer’s warranty. We can quote for the whole job, from supply to commissioning.
What air conditioning repair can’t fix
A few issues sit outside what this work can do:
- No power to the building at all
- Cooling that falls short because the system is too small
- A building problem rather than a system fault
If in doubt, call 07833 053749 or use the quote form and we’ll say what we think.
Where we work
- Wall-mounted split systems
- Ducted systems
- Ceiling cassettes
- Heat pumps
- Multi-split systems
- VRF systems
After we’ve gone
Simple habits make a real difference. Our advice:
- Check the settings and the remote’s batteries first
- Have the system serviced once a year
- Turn the system off if it’s dripping water
Once the fault is fixed, we test the system in operation. We confirm it’s working properly and look for anything else that needs attention, and we tell you about anything we noticed.
Small changes are worth acting on. A drip, a new noise, a weaker airflow or an occasional error code is often the first sign of a fault and catching it early keeps the repair simpler.
Leave it or put it right?
For a newer system, a fault may be covered on the manufacturer’s terms. Send us the make, model and installation date, and we’ll explain how the manufacturer’s warranty is likely to apply before any chargeable work. In London, hot spells can bring a rush of calls, so planning the work in Millbank before summer avoids the wait.
What you pay depends on the system and the number of rooms or units, how easy the units are to reach and what the work involves. We give you a fixed price before we start, so there are no surprises.

What a repair looks like in Millbank
About 47% of homes in Millbank and the neighbourhoods around it were built before 1919, according to the Valuation Office Agency’s council tax figures, and Census 2021 figures found about 94% of households live in flats. Balcony, roof or high wall? Knowing where a flat’s outdoor unit is helps us bring the right access kit. In London buildings, outdoor units can be on roofs or in light wells, so let us know where yours is. The centre of Millbank lies within the Broadway and Christchurch Gardens Conservation Area. There are 33 conservation areas within a mile of the centre of Millbank. Listed buildings are part of the picture here: about 415 within half a mile of the centre, such as The Great Cloisters (grade I). Swapping an outdoor unit on a listed building or in a conservation area may need consent, so we will flag it if a replacement is needed.
