Air conditioning repair in Dunsden Green

Keeping the system healthy

Once we’ve finished, these simple steps help:

  • Rule out the simple causes first: filter, mode and temperature
  • Leave a tripping breaker off and call us
  • Turn the system off if it’s dripping water

Once the fault is fixed, we test the system in operation. We confirm it’s working properly and look for anything else that needs attention, and we tell you about anything we noticed.

Use the system sensibly. Choose the right mode and a moderate set temperature, and keep doors and windows closed while it runs and the system doesn’t have to work as hard.

Landlords, agents and facilities managers

Under the GB F-gas rules, responsibility for leak checks is shared between whoever operates the equipment and the engineers who work on it. Where a building is let or managed, the lease or contract should make clear who looks after the system and we are happy to deal with whoever it is.

Bigger systems bring extra duties: systems with an effective rated output over 12 kW need a TM44 inspection by an accredited energy assessor at least every 5 years. We arrange the inspection, get the system ready and put right anything it picks up.

Common questions in Dunsden Green

Is there an emergency air con repair line for Dunsden Green?

Yes: ring the emergency line, day or night, from anywhere in Dunsden Green. Say what the system is doing and whether it shows a code, and we will advise on the next step.

Is Dunsden Green within the area you cover?

Yes. Dunsden Green is within the area we cover across London and the South East. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.

Why is my air conditioning blowing warm air?

Common causes are a blocked filter, the wrong mode or set temperature, an outdoor unit that cannot breathe, a failed sensor or board, or low refrigerant from a leak. Check the filter and the settings first, then ring us on 07833 053749 or fill in the contact form if it’s still not cooling.

Do you look at the job first?

Yes, always. We diagnose before we treat: the survey shows what’s needed, where things go and what access we need and the fixed price is built on it.

Whose job is it to check the system for leaks?

Whoever operates the equipment, together with the technicians who service it. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We can tell you which band your system falls into.

How long does the work take?

We’ll confirm the time with your quote. As a guide, the work takes as long as the fault needs, from a quick fix to a return visit for parts.

What does F-Gas certified mean?

Anyone installing, repairing or servicing the refrigerant side must be qualified, and their company certified. Ask to see proof before you book anyone and we will gladly show you ours.

Before you call an engineer

Some faults have simple causes you can check first: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If the breaker trips a second time, leave it off and call us on 07833 053749 or fill in the contact form.

Good habits make our visits easier, not unnecessary. Simple care keeps the air moving through the system, but the refrigerant circuit, the electrics and the parts you can’t see still need an engineer at the interval the manufacturer recommends.

When air con fails in Dunsden Green

Valuation Office Agency council tax records date about 61% of homes in Dunsden Green and the neighbourhoods around it to the post-war years, 1945 to 1972, and about 79% of households live in detached or semi-detached houses, according to the 2021 Census. Tell us where your outdoor unit is and how to reach it, so we can plan the visit. Row Lane Farmhouse, listed at grade II*, is one of roughly 7 protected buildings and structures in the half-mile around Dunsden Green’s centre. Swapping an outdoor unit on a listed building or in a conservation area may need consent, so we’ll flag it if a replacement is needed.

The rating label on the unit gives the model number, which helps us bring the right parts. Schools such as St Martin's Catholic Primary School can report a fault on the 24/7 line and have non-urgent work done out of term.

What we do, step by step

The visit has three parts, a bit like a doctor’s appointment: look, put right and sign off. First we check the system or the space against the plan, then the work itself, and finally everything is tested, recorded and explained. Most of the time goes on the middle part, which takes as long as the fault needs, from a quick fix to a return visit for parts. If a lane or gateway near Dunsden Green is tight for a van, let us know and we will plan for it.

  1. Diagnose: test the system until the cause is clear.
  2. Next, a plain explanation and a fixed price.
  3. If the repair isn’t worth doing, we say so and explain the options.
  4. The treatment: the repair itself, with any leak found and fixed before recharging.
  5. Finally, a check that it’s working and a record of what we did.

Getting ready for the visit

  • Arrange for someone to be there to let us in
  • Mention any parking restrictions near the property
  • Find the manual or the paperwork for the system, if you have it
