Fixed-price quotes for air conditioning repair in City of Westminster

The survey or diagnosis tells us what the work involves. We look at:

  • How many units are involved
  • The electrical supply and whether a new circuit is needed
  • The brand, model and parts involved

Homes, offices, shops and public buildings are all priced the same way: what’s needed, how we reach it, the parts and the labour. Call for a fixed-price quote and we’ll explain each part.

What we need to know

What to send for a quote:

  • A few pictures of the room and the wall the unit is on, or will go on
  • Any previous service or F-Gas records
  • A short video of any fault, such as a noise or a flashing light

Published ranges are a starting point; the quote is built on your property, because no two buildings, rooms or systems are the same. Once we have looked at the job, from pictures or on a survey, you get a fixed price. To start, phone us on 07833 053749.

What air conditioning repair can’t fix

In fairness, some problems need a different answer:

  • A room that overheats because of the building, such as a lack of shading or ventilation (the system may need help, not a repair)
  • A refrigerant fault on an R22 system (new R22 can’t be used for servicing, so replacement is normally the answer)
  • An old system with obsolete parts

If you’re not sure, just give us a ring on 07833 053749 or email us and we’ll give you a straight answer.

What the work covers

  • Wall-mounted split systems
  • Heat pumps
  • VRF systems
  • Multi-split systems
  • Ducted systems

City of Westminster questions

What’s the best way to get a price for air conditioning repair in City of Westminster?

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 City of Westminster out of hours?

City of Westminster is within our area, and the emergency line is open 24/7. Say what the system is doing and whether it shows a code, and we will advise on the next step.

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 a legal requirement, and manufacturers expect it for their warranty too. We’re happy to quote for the full job, supply to commissioning.

How quickly will you reply?

On the same working day you contact us. After that, we agree a survey, diagnosis or installation date that suits you, with a fixed price before work starts.

Is there a survey before the work?

Yes. Every job is looked at first, either on a site survey or from pictures and details for simple jobs. Then you get a fixed-price quote.

Why is my air conditioning blowing warm air?

It can be anything from a dirty filter to a refrigerant leak. We read any fault code and test the system to find which and you get a fixed price before the repair.

How long does the work take?

We will confirm the time with your quote. Most of the time, it takes anything from an hour or so to a full day, depending on the fault and the parts.

What happens on the day

Think of the visit in three stages: diagnose, treat and sign off. First we check the system or the space against the plan, then the work itself, and finally we test, record and explain. The middle part takes longest, and that takes a single visit for many faults, while some repairs need a second visit once parts arrive. Some blocks in City of Westminster need contractor details in advance, so tell us what your building needs.

  1. It starts with the symptoms: what the unit is doing, the make and any code on the display.
  2. The engineer reads the fault codes and checks the electrics, airflow, drain and refrigerant circuit.
  3. You get a plain explanation of the fault and a fixed price for putting it right.
  4. With your agreement the part is replaced or the fault put right, and refrigerant work goes in the F-Gas log.
  5. We run the system, check it’s working properly and note anything else that needs attention.

Before we arrive

  • Tell us about parking and loading
  • Dig out any previous service or F-Gas records
  • Arrange for someone to be there to let us in

Getting a quote

Every quote starts with a look at the job, either on a site survey or, for simple jobs, from your pictures and details. After that, we send a fixed price so you know the cost before we begin.

Rented and managed buildings

If you look after several properties, we can plan visits across the portfolio and price them together. Each property gets its own records, so the files stay tidy.

Records are where property maintenance often slips. Each visit produces a dated record, plus the F-Gas records where refrigerant is involved, ready for a tenant, a buyer or an inspection.
