How we handle air conditioning repair in Mildmay
Our emergency line runs 24/7 for urgent breakdowns, from an overheating comms room to water leaking from a unit. Ring 07833 053749 with the make, what’s happening and any code and we will talk you through what happens next. If the problem is ice forming on the indoor unit or pipes and new noises from the system, we can sort it out.
Many buildings in Mildmay have a managing agent or security desk, so let us know who needs to know we’re coming. Outdoor units on roofs may need a key, a permit or an escort, and we plan for that before we arrive.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. Where yours does, a regular service with us keeps that side in order, and every service is written up.

When air con fails in Mildmay
The middle of Mildmay is part of a conservation area. 13 conservation areas lie within a mile of central Mildmay. Church of St Matthias, listed at grade I, is one of roughly 110 protected buildings and structures in the half-mile around Mildmay’s centre. For most visits that makes no difference. It only comes up when an outdoor unit has to be replaced on a protected building. About 48% of homes in the Mildmay area were built before 1919, according to VOA council tax data, and about 81% of households live in flats, according to the 2021 Census. In flats, outdoor units are often on balconies, roofs or high walls, so tell us how we reach yours. In London, access to outdoor units on roofs and balconies can need planning, so tell us how to reach yours.
Schools such as Newington Green Primary School can report a fault on the 24/7 line and have non-urgent work done out of term.

Questions from Mildmay
Do you cover Mildmay for emergency air conditioning repairs?
Yes: ring the emergency line, day or night, from anywhere in Mildmay. Say what the system is doing and whether it shows a code, and we’ll advise on the next step.
What’s the best way to get a price for air conditioning repair in Mildmay?
Send us pictures 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 look at a system you didn’t fit?
Yes. Systems fitted by other companies are fine from all the leading brands. Send us the make and model, and any records you have.
Why is my air conditioning icing up?
The coil gets too cold when air cannot move across it or when the refrigerant charge is low. Check the filter first, and if it’s clean, the system needs a diagnosis.
Do you look at the job first?
Yes. For simple jobs, pictures and a few details can be enough, while bigger systems and repairs that need testing get a visit.
What warranty do I get?
It’s the manufacturer’s, and the terms are theirs. Some brands make regular servicing a condition so it’s worth keeping the service records.
Why isn’t my air con cooling?
It could be a dirty filter, the wrong settings, a blocked outdoor unit, a sensor or board fault, or a refrigerant leak. Check the filter and the settings first, and if that does not fix it, give us a ring on 07833 053749 or fill in the contact form.
What we are called out for in Mildmay
An error code is the unit’s own diagnosis, in shorthand. 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.
Look out for any of the following:
- Ice on the pipework or the coil
- A system that keeps cutting out
- New noises from the system
For a home or office near Dalston Kingsland station, tell us the make, model and error code when you call, so we can plan the repair.
What your quote should include
- Whether the price is fixed or an estimate
- What happens if the job turns out to be different on the day
- Whether a new circuit is included and who certifies it
Landlords, agents and facilities managers
Records are where property maintenance often slips. Each visit produces a dated record, with F-Gas records wherever refrigerant work is involved, ready for a tenant, a buyer or an inspection.
From a single flat to a whole estate, you get the same standard: diagnosis, a fixed price, access agreed with the people on site and paperwork at the end.
Why it’s worth doing now in Mildmay
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, so for older systems we compare the cost of a repair with a replacement. Hot weather is when everyone in London wants air conditioning, so it’s easier to plan the work in Mildmay early.
One room or a whole building, the quote is built the same way: what needs doing, how we get to it and what it needs. You’ll have a fixed price before any work starts, and the quote sets out the VAT.

“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.”
