Air conditioning repair for homes and businesses in High Barnet

Diagnosis call-outs start from £75 + VAT. Once we know the cause, you get a fixed price for the repair before any work goes ahead, so you can decide with the facts in front of you. Common call-outs are for a fault code on the display and water dripping from the indoor unit, across ceiling cassettes, heat pumps and wall-mounted split systems.

London systems in High Barnet often run long hours in summer, and that’s when faults show: weak cooling, water leaks, error codes or a unit that will not start. The error code on the display, the make and the model are the most useful things to send us.

For a fault on a system that may still be under warranty, send us the make, model and installation date. We’ll tell you how the manufacturer’s warranty is likely to apply before any chargeable work goes ahead.

Different systems, different jobs

Circuit boards and sensors

Testing comes before any part is replaced, so you don’t pay for a part that wasn’t the problem. Some parts need ordering from the manufacturer, and we tell you if so.

VRF systems

On larger VRF systems, the refrigerant charge can be big enough to need regular leak checks under the F-gas rules. Leak repairs are written into the F-Gas records for the operator’s records.

Signs you need air conditioning repair in High Barnet

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.

Customers typically contact us after spotting one of these:

  • A system that won’t switch on
  • Rattling, buzzing or grinding noises
  • Water leaking from the unit or through the ceiling

Schools such as Foulds School can report a fault on the 24/7 line and have non-urgent work done out of term.

What your quote should include

  • Whether testing, commissioning and paperwork are included
  • Whether the electrical work is done by a registered contractor, such as NICEIC approved
  • Whose warranty applies, and on what terms

Your questions about air conditioning repair in High Barnet

Is High Barnet in your area for air conditioning repair?

Yes. We work across London and the South East from our base in East Grinstead, and High Barnet is part of that. To start, phone 07833 053749 or drop us a line with a few pictures.

Do you cover High Barnet for emergency air conditioning repairs?

The emergency line is open around the clock, and High Barnet is one of the places it covers. Say what the system is doing and whether it shows a code, and we’ll advise on the next step.

Can you repair an R22 air conditioning system?

R22 is an ozone-depleting refrigerant, and new R22 cannot be used for servicing. Some non-refrigerant faults can be repaired if parts are available, but a leak typically makes replacement the sensible route. We’ll set out the options and quote for a replacement where it makes sense.

Can landlords and managing agents book you?

Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size in High Barnet and across Greater London. Tell us who should receive the paperwork.

What does the error code on my air conditioning mean?

Codes differ by brand, and the same code can cover several faults. Tell us the code, the make and the model, and we’ll diagnose the fault on site.

Can we book visits on a schedule?

Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Each visit is written up and F-Gas records kept where they apply.

Do you survey before quoting?

Yes. Every job is looked at first, either on a site survey or from photos and details for simple jobs. A fixed-price quote follows.

For landlords and property managers

Bigger systems bring extra duties: a TM44 inspection by an accredited energy assessor is required at least every 5 years for systems over 12 kW. We can arrange it, prepare the system for it and fix what it finds.

Managing agents often deal with us directly. Send the address, what’s needed and how access works and we’ll come back with a fixed-price quote.

What we do, step by step

Where something has to be switched off during the work, we agree it with you first, so you can plan around it. In a business, work can often be done one area at a time. The work takes a single visit for many faults, while some repairs need a second visit once parts arrive. Send us a few phone pictures and we can often price a straightforward job in High Barnet before visiting.

  1. You describe the fault, the make and any error code, ideally with a photo.
  2. We diagnose on site, checking the codes, electrics, airflow, drain and refrigerant pressures.
  3. We explain the cause and give you a fixed price for the repair before any work goes ahead.
  4. The repair is carried out, and any refrigerant work is leak tested and recorded.
  5. The system is run and checked in every mode, and we tell you about anything else we noticed.

How to prepare

  • Plan for pets to be kept clear during the visit
  • Have the make and model of any existing unit to hand
  • Tell us about access, such as roof hatches, high walls or locked plant areas

How to get a quote
