Air conditioning repair in Waltham

A diagnosis call-out is from £75 + VAT. Once we know the cause, you get a fixed price for the repair before any work goes ahead and nothing goes ahead without your say-so. The work covers VRF systems, ducted systems and heat pumps, and people most often call us about rattling, buzzing or grinding noises and frost on the pipework.

We plan the trip to Waltham so the repair can be finished in one visit where possible, though some parts have to be ordered from the manufacturer.

Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we explain those terms on your quote. Terms differ from brand to brand, and we are happy to talk you through them.

Let and managed properties

Running several properties is easier with one contractor. Our area covers Greater London and the South East, so a run of properties can go into one programme and kept to a regular schedule.

The F-gas rules share responsibility for leak checking between the equipment’s operator and the service technicians. In a let or managed building, it’s worth agreeing who that operator is, and we can work for either side.

Air conditioning repair around Waltham

The last census (2021) found about 71% of households in detached or semi-detached houses. Access to the outdoor unit is the one detail that most changes how a visit is planned. Waltham’s centre is no more than about a third of a mile from the Waltham Conservation Area. In the mile around Waltham’s centre, 3 conservation areas have been designated. About 10 listed entries lie within half a mile of central Waltham, Church of St Bartholomew (grade I) among them. Day-to-day work on an existing system is not affected; a replacement outdoor unit on a protected building might be.

A unit that keeps tripping or showing the same code is worth a proper diagnosis. If the display shows a code, write it down: it helps narrow down the fault.

After we have gone

Here’s the after-treatment advice, in brief:

  • Check the settings and the remote’s batteries first
  • Send us a photo of any code on the display
  • Keep to the service interval the manufacturer recommends

If a repair doesn’t make sense, you will hear it from us, with the reasons. If replacement is the better option, we can quote for it on the same visit.

Clean the filters regularly. Blocked filters cut airflow, which can lead to poor cooling, ice on the coil and drips, so keep them clean as the manual describes.

System by system

Wall-mounted split systems

Wall-mounted splits are the systems we repair most often. Typical faults include blocked drains, dirty coils and filters, failed fan motors, sensor faults and refrigerant leaks, and most are diagnosed on the first visit.

Circuit boards and sensors

Boards and sensors are the system’s nervous system. Sensor faults can stop the system or confuse it and boards can fail with age or after electrical problems.

How it works

We book the visit for a day and time that suit you, and we let you know if plans need to move. When we arrive, we check the job against the survey or the photos you sent. If something is different, we talk it through with you before carrying on. From there, the work takes as long as the fault needs, from a quick fix to a return visit for parts. Photos of the existing unit help with repairs and servicing in Waltham.

  1. Tell us the make, the symptoms and any error code, and send a photo of the display if you can.
  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. 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.

Getting ready for the visit

  • Find the manual or the paperwork for the system, if you have it
  • Let us know if the units are on a roof, a high wall or in a locked area
  • Keep pets out of the rooms we’re working in

Getting a price

The quickest way to a quote is to send photos: 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. Add the address and what you’d like done, and many jobs can be priced from that.

Common questions in Waltham

Is Waltham within the area you cover?

Yes, smaller places are covered as well as towns. Send a few details and pictures, and we reply the same working day.

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

The emergency line is open around the clock, and Waltham is one of the places it covers. Have the make, model and error code ready, and we’ll talk you through what happens next.

What does F-Gas certified mean?

F-Gas certification shows a company is approved to work on equipment containing fluorinated gases, such as the refrigerant in air conditioning and heat pumps. In Great Britain, that certification is a legal requirement, not an optional extra, and AirCon Doctor is certified.

Which brands do you work with?

We install and work on the leading makes, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we’ll take it from there.

Can I do the refrigerant work myself?

Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That is the law, not just our preference, and it also matters for the manufacturer’s warranty. We can quote for the whole job, from supply to commissioning.

When will I hear back?

You’ll hear from us the same working day. For a breakdown that cannot wait, call our 24/7 emergency line.

Do you work on systems someone else installed?

Yes. Systems fitted by other companies are fine, on all the main brands. Send us the make and model, and any records you have.

A customer’s words

“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
