What we’re called out for in Charleshill

Some faults stop the unit completely: fan motors, boards, interconnecting cables and tripped breakers. A breaker that trips a second time should be left off and call us.

Reasons to give us a call include:

  • A system that runs but does not cool the room
  • A unit that has lost refrigerant
  • Weak airflow from the indoor unit

If a system fails at a school such as Waverley Abbey CofE Junior School, our 24/7 line takes the call, and planned repairs can wait for the holidays.

Our hiring checklist

Air conditioning repair for homes and businesses in Charleshill

Across Charleshill, every repair begins with a diagnosis: the engineer reads the fault codes and checks the electrics, the airflow, the condensate drain and the refrigerant pressures and temperatures. After that, you get a plain explanation and a fixed price for the repair. The work covers multi-split systems, ceiling cassettes and wall-mounted split systems, and people most often call us about water dripping from the indoor unit and a system that runs but doesn’t cool the room.

A visit to Charleshill is planned so we can usually finish in one go, unless a part has to come from the manufacturer.

Equipment warranty comes from the manufacturer, on its own terms, and we set them out on your quote. Terms differ from brand to brand, so we go through them with you rather than leave you to find the small print.

What the work involves, system by system

Circuit boards and sensors

Testing comes before any part is replaced because swapping parts on a guess wastes money. Parts may need ordering and we’ll explain any wait.

VRF systems

In a VRF system, many indoor units share outdoor plant. Faults are diagnosed through the system’s own fault codes and controls, then confirmed by testing, and repairs are priced before they go ahead.

What happens on the day

You do not need to do much on the day. Just let us in and point us to the units, or to where they’ll be fitted, and we take it from there. Before we leave, the area is tidied and we explain what we have done. If a lane or gateway near Charleshill is tight for a van, let us know and we’ll plan for it.

  1. First the diagnosis: fault codes read, electrics and airflow checked, drain and refrigerant tested.
  2. Prescribe: tell you the cause and the fixed cost of the cure.
  3. If the repair isn’t worth doing, we say so and explain the options.
  4. Treat: carry out the repair, sealing any leak before refrigerant goes back in.
  5. Sign off: prove it works and record the visit.

Preparing for the visit

  • Keep pets and children away from the work area
  • Clear a path to the units and the space around them
  • Give us access to the outside wall, roof or yard where the outdoor unit sits

Ask for a quote

The quickest way to a quote is to send pictures: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Tell us the address and what you need, and simple jobs can often be priced without a visit.

About 80% of households live in detached or semi-detached houses, according to the 2021 Census. If the outdoor unit is high up or behind a locked gate, mention it when you book. About 6 listed entries lie within half a mile of central Charleshill, Firbank House and Hill Cottage (grade II) among them. That only matters for replacements, where a new outdoor unit on a protected building can need consent.

Common questions in Charleshill

Who do I call if my air conditioning fails in Charleshill out of hours?

Yes. Our 24/7 emergency line covers Charleshill. Tell us the make, model and any error code when you call; repair call-outs start from £75 + VAT.

Is Charleshill in your area for air conditioning repair?

Yes. Charleshill is one of the places we cover. Just ring 07833 053749 or write to us at info@aircondoctor.co.uk with a few details.

Who has to arrange F-Gas leak checks?

The F-gas rules share it between the equipment’s operator and the engineers who work on it. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.

Do you work on systems someone else installed?

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

What causes water to leak from an air conditioning unit?

The condensate drain or pump is the usual cause: a blocked pipe, a kinked hose or a failed pump. Switch the unit off to avoid water damage, then call us.

Why isn’t my air con cooling?

There are several possible causes, from simple to serious. Diagnosis confirms the cause and you get a fixed price before the repair.

Can landlords and managing agents book you?

Yes. From a single let flat to offices, shops and public buildings, the approach is the same: a look first, a fixed-price quote and written records.

What air conditioning repair can’t fix

Not every problem is solved by air conditioning repair, and we’d rather say so up front. It doesn’t solve:

  • 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 leak on an old R22 system
  • Cooling that falls short because the system is too small

If you’re not sure, just ring 07833 053749 or fill in the contact form and we will give you a straight answer.
