Air conditioning repair in Longfield Hill

Older systems raise a fair question: repair or replace?. A system with a failed fan motor may be well worth repairing, while one with a failed compressor might not be. You get an honest view based on the fault, the parts, the refrigerant and the room. If you’re dealing with an error code or flashing light on the unit and water dripping from the indoor unit, we can sort it out.

We plan the trip to Longfield Hill so the repair can be finished in one visit where possible, unless a part has to come from the manufacturer.

We are an F-Gas certified company, NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

Before you call an engineer

For air conditioning, cleaning the indoor unit’s filters is the main job owners can do where the manufacturer’s manual explains how. They come out, get a gentle clean and go back only when they’re dry. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.

Refrigerant is off limits for anyone without the right qualifications. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and escaping refrigerant can cause cold burns. A suspected leak is our job, not yours.

Different systems, different jobs

Ducted and cassette systems

Water through a ceiling below a cassette or ducted unit needs prompt attention. The cause is normally the condensate pump, a blocked drain or a tray that’s overflowing, and we check all three.

Multi-split systems

With several pipe runs, finding a leak on a multi-split takes method. Each run is checked, then repair, pressure test and recharge.

Looking after your system

Aftercare is straightforward, and it helps at the next service:

  • Leave a tripping breaker off and call us
  • Turn the system off if it’s dripping water
  • Keep to the service interval the manufacturer recommends

After a repair, the basics matter: clean filters and a clear outdoor unit help the system run as it should. A yearly service catches problems before they become breakdowns.

Filter cleaning is the simplest prevention there is. Clogged filters starve the unit of air, and that can cause ice, drips and poor performance, so keep them clean as the manual describes.

Common questions in Longfield Hill

Do you cover smaller places like Longfield Hill?

Yes, and the size of the place makes no difference to how we work. Send a few details and pictures, and we reply the same working day.

Is Longfield Hill in your area for air conditioning repair?

Yes. Longfield Hill is one of the places we cover. Get in touch with the details and we reply the same working day.

Is the equipment covered by a warranty?

Warranty is the manufacturer’s own, on its terms. Terms differ by brand, and we set them out on your quote.

Can you come out for an emergency air conditioning repair?

Yes. We have a 24/7 emergency line for urgent breakdowns. Ring 07833 053749 with the make, what’s happening and any code and we’ll talk you through what happens next.

Why does F-Gas certification matter?

Certification shows a business is approved to work on systems that hold F gas refrigerant. In Great Britain, that certification is a legal requirement, not an optional extra, and AirCon Doctor is certified.

Do you work on all makes?

Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For a new system, we suggest the make and model that suit the property and tell you why.

Why is my air conditioning showing a fault code?

Each manufacturer uses its own codes, and one code can have more than one cause. Tell us the code, the make and the model, and we will diagnose the fault on site.

How the visit works

There’s very little for you to do on the day. Someone needs to let us in and show us the units, or where they’re going, and we take it from there. At the end, we tidy up and run through the work with you. Visits to Longfield Hill are agreed with you in advance and planned so the job can be finished in one trip where possible.

  1. First the diagnosis: fault codes read, electrics and airflow checked, drain and refrigerant tested.
  2. Next, a plain explanation and a fixed price.
  3. Where a repair doesn’t make sense, you will hear it from us, with the alternatives.
  4. Then the fix, with leaks repaired before any refrigerant is added.
  5. The sign-off: the system tested in operation and the work recorded.

Before we arrive

  • Give us access to the outside wall, roof or yard where the outdoor unit sits
  • Tell us about parking and loading
  • Keep pets and children away from the work area
