Air conditioning servicing in Belsize

A manufacturer’s warranty can come with conditions, and regular servicing may be one of them. The terms differ from brand to brand, so it’s worth reading yours and we’re happy to go through them with you. You get a record of each service to keep with the warranty paperwork. We’re often asked to deal with ice forming on the pipework or outdoor unit and air conditioning that isn’t cooling as well as it did, on VRF systems, air-to-air heat pumps and wall-mounted split systems.

We plan the trip to Belsize and can service more than one unit in one visit.

Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. If that applies to your system, booking the service on time keeps the record straight and each visit is recorded.

What you can do yourself, and what needs us

Some faults have simple causes you can check first: check the mode, the set temperature, the remote’s batteries and the breaker. If a breaker trips again after you reset it, leave it off and call us on 07833 053749 or write to us at info@aircondoctor.co.uk.

Never try to top up, release or handle refrigerant yourself. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and refrigerant lines can cause cold burns. A suspected leak is our job, not yours.

Do you need air conditioning servicing in Belsize?

Each indoor unit makes water when it cools, and that water needs a clear route out. Sludge and debris can block the tray, the pipe or the pump and the result is drips from the indoor unit.

Most people get in touch after spotting something like this:

  • Noisy fans or rattling from the outdoor unit
  • Leak check records that need bringing up to date
  • Water dripping from the indoor unit

Most homes book one service a year; busy offices and shops may want more.

Questions to ask before you book

  • What paperwork you’ll receive afterwards
  • Whether the quote is a fixed price
  • Exactly what the price includes, from supply and fitting to commissioning

Choosing an air con installer

What we do, step by step

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 around an hour for one indoor and one outdoor unit, with extra time for each additional indoor unit. Photos of the existing unit help with repairs and servicing in Belsize.

  1. A date is fixed and the service price confirmed in advance.
  2. Before any cleaning, the system is run so we can see how it behaves.
  3. Filters, coils, fans and drains are cleaned and cleared.
  4. The electrics, controls and refrigerant performance are checked, with a leak check where required.
  5. A final test run follows, then you get the service record.

Before we arrive

  • Let us know where we can park and unload
  • Clear access to the fuse board
  • Have the make and model of any existing unit to hand

Questions from Belsize

How often should air conditioning in Belsize be serviced?

For most homes, once a year. Some manufacturers’ warranty terms ask for regular servicing, so it’s worth keeping the records.

Is Belsize in your area for air conditioning servicing?

We do: Belsize falls inside our working area. Tell us a little about the job and we’ll take it from there.

Do you work on systems someone else installed?

Yes. We look at it first and tell you what we find, including anything about the original installation that needs putting right. Any work is priced before it goes ahead.

Is an F-gas leak check a legal requirement for my system?

Under GOV.UK guidance, systems of 5 to under 50 tCO2e need a check at least every 12 months, and 50 to under 500 tCO2e every 6 months. Fitting leak detection lets you double the interval and we’ll confirm which band applies.

What do you check on an air conditioning service?

Filters, coils, fans and the condensate drain are all cleaned and checked. The electrics, controls and refrigerant circuit are tested too, with an F-gas leak check where the system requires one.

Why use an F-Gas certified company?

Companies working on equipment that contains F gas must be certified by an approved body, and each engineer needs the right qualifications too. It’s how you know the refrigerant is being handled legally and safely.

Can I have a maintenance contract for my air conditioning?

We do. With a contract, the frequency and the scope of each visit are written down, at a fixed price agreed with your quote. It takes the scheduling off your plate.

On the National Heritage List, around 21 entries fall within 0.5 miles of the middle of Belsize; Belsize House (grade II) is one.

Keeping the system healthy

Looking after the system is mostly common sense. A few tips:

  • Check the condensate pipe outside is not blocked or crushed
  • Know your manufacturer’s servicing conditions
  • Keep plants, bins and stored items away from the outdoor unit

Run the system for a while after the visit and check it feels right. If you notice anything unusual, ring us on 07833 053749 or write to us at info@aircondoctor.co.uk and we’ll look into it.

Keep the area around the outdoor unit clear. Plants, bins and stored items piled around it get in the way of the air it needs and should be moved away.

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.”
