Air conditioning servicing in South Hampstead

Keeping the system healthy

Aftercare is straightforward, and it helps at the next service:

  • Shut doors to the room so the system is not cooling the whole house
  • Check the condensate pipe outside isn’t blocked or crushed
  • Book the service at least once a year

If we find a fault, we explain it and give you a price to put it right. We don’t carry out extra work until you’ve agreed it and the decision is always yours.

Make sure condensate pipes outside are not crushed, blocked or buried. If the outlet is blocked, the water has to go somewhere, and that is usually back towards the indoor unit.

Air conditioning servicing for homes and businesses in South Hampstead

Every hour, an indoor unit draws the room’s air through its filter and over its coil again and again. Whatever is in the air, from dust to pet hair, collects on the filter and coil. Servicing removes it, so the system can move air properly and the drain can do its job. The work covers ducted systems, air-to-air heat pumps and multi-split systems, and people most often call us about weaker cooling than last year and condensate leaking into the room.

In a London area like South Hampstead, many systems run hard in summer and for heating in winter, so a yearly service keeps them efficient. Outdoor units on balconies and roofs pick up city dust and debris, and a clean coil cools better.

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, as a manufacturer or a future engineer may ask to see them.

Keeping systems in South Hampstead running

About 47% of homes across South Hampstead and its surrounding area were built before 1919, according to Valuation Office Agency council tax records, and about 90% of households live in flats, according to Census 2021 figures. Balcony, roof or high wall? Knowing where a flat’s outdoor unit is helps us bring the right access kit. London outdoor units collect city dust and grime, so the outdoor coil gets particular attention on a service. Roughly a third of a mile or less from central South Hampstead, you reach the Belsize Park Conservation Area. Draw a one-mile circle round the middle of South Hampstead and it takes in 12 conservation areas. Belsize Fire Station, listed at grade II*, is one of roughly 123 protected buildings and structures in the half-mile around South Hampstead’s centre. Should a unit ever need replacing on a listed building or in a conservation area, ask us about consent first.

If you look after a school such as The UCL Academy, servicing is easiest in the holidays.

The process

The work area is kept tidy throughout, with sheets down and mess cleared as we go. If we need to drill through a wall, we agree the spot with you first. On site, it takes an hour or so for a single wall-mounted unit, longer for a multi-split system. In a London area like South Hampstead, parking and access are worth sorting out before the day.

  1. We ask about the system: the make, the number of indoor units and any problems you’ve noticed.
  2. We run the system first and see how it’s performing.
  3. Dust and grime come off the filters and coils, and the drain is flushed so water runs away properly.
  4. Electrical connections, controls and refrigerant performance are checked, with an F-gas leak check where the system requires one.
  5. You get a service record, with anything that needs attention explained.

Getting ready for the visit

  • Unlock any gate, garage or side passage we need
  • Let us know where we can park and unload
  • Clear the space around the indoor unit, or where it will go

Getting a price

Common questions in South Hampstead

Does my air con in South Hampstead need a yearly service?

Usually once a year for homes, more often for busy business systems. Business systems may also need F-gas leak checks, at least every 12 months from 5 tonnes CO2 equivalent.

Is South Hampstead in your area for air conditioning servicing?

We do: South Hampstead falls inside our working area. To start, call us on 07833 053749 or drop us a line with a few photos.

Can you look at a system you didn’t fit?

Yes. We start with a proper look and tell you honestly what we find, including any issues with how it was fitted. You get a fixed price before any work goes ahead.

Do you offer maintenance contracts?

Yes. Tell us what you have and how it’s used, and we will suggest a schedule with a fixed price. Leak checks required by the F-gas rules can be built in for larger systems.

Do you provide F-Gas records?

Yes. It’s your proof of what was done: a dated note of the work, with refrigerant details where they apply.

Do you top up refrigerant during a service?

Not as a routine part of the service. If a system has lost refrigerant, it has leaked from somewhere. Where the checks point to a leak, we explain the options for finding and fixing it.

Which accreditations do you hold?

F-Gas certified, NICEIC approved and MCS certified for heat pumps, plus Checkatrade membership. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.

When to call us in South Hampstead

Filters clog gradually, a little more every day the system runs. Clogged filters choke the airflow, the coil can get too cold and the room takes longer to cool or warm.

If any of these sounds familiar, it’s worth a diagnosis:

  • Humming, rattling or squealing from the system
  • Ice forming on the pipework or outdoor unit
  • Weaker cooling than last year

For an office near South Hampstead station, servicing can be booked before or after working hours.

Before you book anyone

  • What’s in the price and what is not
  • Whether extra work needs your approval first
  • Proof of F-Gas company certification

Questions to ask before you book

Rented and managed buildings

We regularly work with managing agents. Send the address, what’s needed and how access works and we’ll come back with a fixed-price quote.

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.

A customer’s words

“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.”
