How we handle air conditioning repair in Hampstead
A sealed system shouldn’t lose refrigerant, so if it’s low, there’s a leak. Simply adding gas means it will leak away again. We find and fix the leak, pressure test, evacuate and recharge to the manufacturer’s charge and write it up in the F-Gas records. If the problem is weak airflow from the indoor unit and rattling, buzzing or grinding noises, we can help.
Many buildings in Hampstead have a managing agent or security desk, so tell us who controls access. Outdoor units on roofs may need a key, a permit or an escort, which is worth sorting before the visit.
Equipment warranty comes from the manufacturer, on its own terms, and we set them out on your quote. Terms differ from brand to brand, and we’re happy to talk you through them.

How the visit works
Each visit follows the same order: check the plan with you, put the dust sheets down, do the work, test what we have done and explain it all to you. On site, the work takes anything from an hour or so to a full day, depending on the fault and the parts. Managed buildings in London often need contractors booked in, and we can deal with the agent for a job in Hampstead.
- Diagnose: test the system until the cause is clear.
- Next, a plain explanation and a fixed price.
- Where a repair doesn’t make sense, you’ll hear it from us, with the alternatives.
- The treatment: the repair itself, with any leak found and fixed before recharging.
- The sign-off: the system tested in operation and the work recorded.
How to prepare
- Let us know if the units are on a roof, a high wall or in a locked area
- Find the manual or the paperwork for the system, if you have it
- Name a contact who can meet us at the agreed time
How to get a quote
VAT is set out clearly on every quote, and the rate that applies to your job is stated. Homes, businesses and different kinds of work can be treated differently for VAT, so we confirm it on the quote. For a fixed-price quote, ring us on 07833 053749 or fill in the contact form.

Air conditioning repair in Hampstead: the local picture
VOA council tax data put about 68% of homes in the Hampstead area before 1919, and the last census (2021) found about 84% of households live in flats. Outdoor units serving flats can be awkward to reach, so let us know where yours is. In London, access to outdoor units on roofs and balconies can need planning, so tell us how to reach yours. Hampstead’s centre falls inside the Redington Frognall Conservation Area. 10 conservation areas lie within a mile of central Hampstead. About 362 listed entries lie within half a mile of central Hampstead, Institute of St Marcellina (grade I) among them. That only matters for replacements, where a new outdoor unit on a protected building can need consent.
If your system near Finchley Road & Frognal station stops in a hot spell, our 24/7 line is open. Schools such as Fitzjohn's Primary School can report a fault on the 24/7 line and have non-urgent work done out of term.

For landlords and property managers
Records are where property maintenance often slips. Every visit is written up, with F-Gas records wherever refrigerant work is involved, so you can show what was done and when.
Where a tenant occupies the property but the landlord owns the system, it’s worth checking the agreement for who looks after the system. We can quote either party and send the records to whoever needs them.

What the work involves, system by system
Circuit boards and sensors
Circuit boards and temperature sensors control how the system runs. Sensor faults can stop the system or confuse it, and boards can fail after a power surge or with age.
Fans and compressors
Fans are the moving parts most likely to wear, often starting with a noise or weaker airflow. A worn fan motor can normally be replaced, depending on parts availability.

Looking after it afterwards
A little care keeps the system in better shape. We recommend:
- Turn the system off if it’s dripping water
- Don’t keep resetting a breaker that trips
- Check the filter, the mode and the set temperature before calling us
Keep the filters clean and the outdoor unit clear after the repair: clean filters every few weeks in heavy use and space around the outdoor unit. An annual service is the best way to catch the next fault before it stops the system.
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.
From one of our customers
“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.”
