Air conditioning repair in Mottingham: the local picture
Valuation Office Agency council tax records show about 48% of homes across Mottingham and its surrounding area date from 1919 to 1939, and about 41% of households live in terraced houses, according to the last census (2021). Terraced homes rarely have side access, so say whether we reach the back through the house, a garage or a rear lane. In London, access to outdoor units on roofs and balconies can need planning, so tell us how to reach yours. Listed buildings are part of the picture here: about 3 within half a mile of the centre, such as The Grange Eltham College Junior School (grade II). That only matters for replacements, where a new outdoor unit on a protected building can need consent.

Air conditioning repair in Mottingham
Refrigerant doesn’t get used up, so if it’s low, there’s a leak. Topping up without a repair only delays the next breakdown. We locate the leak, repair it, test, evacuate and recharge, then record it in the F-Gas records. The work covers ceiling cassettes, heat pumps and multi-split systems, and people most often call us about poor airflow even with clean filters and new noises from the system.
In Mottingham, as across London, air conditioning works hard in hot spells, which is when weak cooling, leaks and error codes tend to appear. A photo of the error code and the unit’s label helps us arrive with the right parts in mind.
Looking after a system is mostly common sense: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. That also helps where the warranty terms ask for regular servicing.

Do you need air conditioning repair in Mottingham?
A unit that runs but does not cool has a few usual suspects: dirty filters, wrong settings, a blocked outdoor unit, a sensor or board fault, or a refrigerant leak. Diagnosis narrows it down.
Look out for any of the following:
- A suspected refrigerant leak
- Air conditioning running but not cooling
- A system that will not switch on
If a system fails at a school such as Marvels Lane Primary School, our 24/7 line takes the call, and planned repairs can wait for the holidays.
Questions to ask before booking
- What the manufacturer’s warranty covers and for how long
- Whether the price is fixed or an estimate
- Whether they hold F-Gas company certification, not just individual qualifications
What we do, step by step
There’s very little for you to do 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’ve done. In a London area like Mottingham, parking and access are worth sorting out before the day.
- Diagnose: test the system until the cause is clear.
- Then the prescription: what’s wrong and what it will cost to put right.
- Where a repair doesn’t make sense, you will hear it from us, with the alternatives.
- The treatment: the repair itself, with any leak found and fixed before recharging.
- Sign off: prove it works and record the visit.
Getting ready for the visit
- Let us know where the consumer unit is
- Let us know if the units are on a roof, a high wall or in a locked area
- Tell us about parking and loading
Getting a price
Some jobs can be priced from pictures, while others need a survey. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, the quote is fixed before anything goes ahead.

Mottingham: your questions answered
What’s the best way to get a price for air conditioning repair in Mottingham?
The easiest way is to ring us on 07833 053749 or drop us a line with a few details and photos. Simple jobs can be priced from photos; otherwise we arrange a site survey and then give you a fixed-price quote.
Is there an emergency air con repair line for Mottingham?
Mottingham is within our area, and the emergency line is open 24/7. Say what the system is doing and whether it shows a code, and we’ll advise on the next step.
How long does the visit take?
That depends on what’s involved, but as a guide it takes a single visit for many faults, while some repairs need a second visit once parts arrive. We’ll confirm it with the quote.
Do you protect the property while you work?
Protection goes down first: sheets over the floor and nearby furniture. Holes and fixings are agreed with you, and we clean up afterwards when we finish.
Who has to arrange F-Gas leak checks?
The operator of the equipment, working with qualified engineers. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We’ll work out which band applies to yours.
My system uses R22. Can it be repaired?
Replacement is typically the better answer. R22 can’t be topped up with new gas, and parts for old models are scarce, so we’ll quote for a modern replacement and explain why.
Do you work on systems someone else installed?
Yes. We work on systems fitted by other installers as well as our own, on all the main brands. Tell us the make and model and send any paperwork you have.
Rented and managed buildings
Facilities teams in offices, schools and public buildings book us too in Mottingham and across Greater London. Work can be phased by floor, zone or building to keep disruption down.
Larger air conditioning systems in buildings need more than servicing: 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.

Safe owner checks
Never try to top up, release or handle refrigerant yourself. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and refrigerant lines can cause cold burns. A suspected leak is our job, not yours.
Owner care supports servicing; it does not replace it. Simple care keeps the air moving through the system, but the refrigerant circuit, the electrics and the parts you cannot see still need an engineer at the interval the manufacturer recommends.
What a customer said
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
