Need air conditioning repair in Clapham Junction?

Landlords, agents and facilities managers

Landlords, letting agents and managing agents book us, not only the people who live or work in the property. Tell us who the contact on site is and who should receive the paperwork, and we’ll keep everyone informed.

Larger air conditioning systems in buildings need more than servicing: 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.

Air conditioning repair for homes and businesses in Clapham Junction

We treat a faulty system the way a doctor treats a patient: diagnose the cause, treat it properly and sign it off when it’s working. Guesswork costs money, and topping up refrigerant on a system with a blocked filter fixes nothing. The work covers wall-mounted split systems, ceiling cassettes and heat pumps, and common reasons people get in touch are a system that needs topping up again and a system that won’t switch on.

In a London area like Clapham Junction, a lot of the systems we repair serve flats and small offices, where the outdoor unit may be on a balcony, a rear wall or the roof. Knowing where the outdoor unit sits, and how to get to it, helps us plan the repair.

Whatever the visit, you get a written record: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. File it with the manual, because it helps with any later warranty question.

Fixed-price quotes for air conditioning repair in Clapham Junction

The diagnosis comes before the price. We look at:

  • The electrical supply and whether a new circuit is needed
  • Whether it’s a simple split or a larger system
  • A single visit or a regular plan

Leaving a fault or an overdue service rarely makes the work cheaper. Faults and wear in a system tend to grow, and a struggling system uses more electricity to do less. If you’re unsure, ring us on 07833 053749 or write to us at info@aircondoctor.co.uk for straight advice and a fixed price.

Helping us quote

A few details help us quote accurately. With your enquiry, please include:

  • Where the outdoor unit is, or where you’d like it
  • Any error code or flashing light on the display
  • Your installation or service records

Photos are enough for some jobs; others need a visit first. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, you get a fixed price before any work is booked.

Clapham Junction: your questions answered

Can I get a fixed-price quote for air conditioning repair in Clapham Junction?

Start with a short message: the address, what you need and a picture or two. We reply the same working day, and the quote is fixed before any work starts.

Do you cover Clapham Junction for emergency air conditioning repairs?

Yes. Our 24/7 emergency line covers Clapham Junction. Have the make, model and error code ready, and we’ll talk you through what happens next.

My system uses R410A. Can it still be repaired?

Yes. We find and fix the leak, then recharge with R410A and record it in the F-Gas records, and we tell you honestly whether a repair is worth it on an older system.

What causes ice on the indoor coil?

The coil gets too cold when air cannot move across it or when the refrigerant charge is low. Check the filter first and if that isn’t it, we’ll find the cause.

Do you work on commercial properties?

Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size across London and the South East. Let us know who the records should go to.

What can I do with an old R22 system?

R22 is an ozone-depleting refrigerant, and new R22 cannot be used for servicing. A fault that doesn’t involve the refrigerant may still be repairable, depending on parts, but a refrigerant leak typically means replacement. We explain the options and quote for a new system if that is the answer.

Do you work on systems someone else installed?

Yes. Systems fitted by other companies are fine from all the leading brands. Tell us the make and model and send any paperwork you have.

How it works

Think of the visit in three stages: diagnose, treat 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. The middle part takes longest, and that takes an hour or two to diagnose most faults, with the repair time depending on what we find. Send us a few phone pictures and we can often price a straightforward job in Clapham Junction before visiting.

  1. Describe the problem and the brand, and mention any code on the display.
  2. The engineer diagnoses the fault on site, testing rather than guessing.
  3. We explain the cause in plain English and give you a fixed price.
  4. Once agreed, the repair goes ahead.
  5. The system is run and checked, and you get a written note of the repair.

Getting ready for the visit

  • Tell us about any building rules, permits or sign-in
  • Arrange for someone to be there to let us in
  • 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 inside and outside of the property where the work is, plus the rating plate of any unit already there. Tell us the address and what you need, and many jobs can be priced from that.
